summary	For a long time the Architecture-Engineering-Construction (AEC) community has had difficulty in communicating the content of their work, not only the various specialties involved, but also to their clients. Studies (Doorst and Cross 2001; Bakhtin 1994) suggest the importance of multi-role collaborative environments in supporting design processes. We are developing a Multi Level Design Review Tool for the AEC industry which allows multiple actors to congregate and interact as agents around a central Building Model. It merges real-time virtual 3D visualization technologies with Industry Foundation Classes (IFC) to support both high levels of semantic content and seamless interoperability.

summary	Digital output from computer modeling represents a significant new method for visualization and fabrication of architecture. The ability to move directly from three-dimensional modeling to real three-dimensional output challenges the need for traditional means of representation such as plan, section, etc. Moreover, the necessity for conversion of architectural intentions into a code (construction documents, shop drawings, etc.) to be translated by the contractor will also be tested with these new potentials in fabrication. This subjugation of traditional forms of representation and fabrication has serious implications for architectural design process and production. The intention of this paper is to scrutinize underlying issues inherent in a design process of developing architectural solutions using the computer both as a tool for threedimensional visualization as well as for guiding three-dimensional fabrication. Precedent of historic expressive architectural form (seen through the lens of fabrication) will be presented to lay the foundation for the examination of new fabrication techniques and structural concerns for computer generated expressive forms. A series of rapid prototype studies from a digital architecture seminar will also be analyzed to outline the need for developing visualization/fabrication process ideas and research into methods for making digital architecture.

title	Toward a procedure of computer simulation in the restoration of historical architecture
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	In the field of architectural design, “visualization¨ generally refers to some media, communicating and representing the idea of designers, such as ordinary drafts, maps, perspectives, photos and physical models, etc. (Rahman, 1992; Susan, 2000). The main reason why we adopt visualization is that it enables us to understand clearly and to control complicated procedures (Gombrich, 1990). Secondly, the way we get design knowledge is more from the published visualized images and less from personal experiences (Evans, 1989). Thus the importance of the representation of visualization is manifested.Due to the developments of computer technology in recent years, various computer aided design system are invented and used in a great amount, such as image processing, computer graphic, computer modeling/rendering, animation, multimedia, virtual reality and collaboration, etc. (Lawson, 1995; Liu, 1996). The conventional media are greatly replaced by computer media, and the visualization is further brought into the computerized stage. The procedure of visual impact analysis and assessment (VIAA), addressed by Rahman (1992), is renewed and amended for the intervention of computer (Liu, 2000). Based on the procedures above, a great amount of applied researches are proceeded. Therefore it is evident that the computer visualization is helpful to the discussion and evaluation during the design process (Hall, 1988, 1990, 1992, 1995, 1996, 1997, 1998; Liu, 1997; Sasada, 1986, 1988, 1990, 1993, 1997, 1998). In addition to the process of architectural design, the computer visualization is also applied to the subject of construction, which is repeatedly amended and corrected by the images of computer simulation (Liu, 2000). Potier (2000) probes into the contextual research and restoration of historical architecture by the technology of computer simulation before the practical restoration is constructed. In this way he established a communicative mode among archeologists, architects via computer media.In the research of restoration and preservation of historical architecture in Taiwan, many scholars have been devoted into the studies of historical contextual criticism (Shi, 1988, 1990, 1991, 1992, 1995; Fu, 1995, 1997; Chiu, 2000). Clues that accompany the historical contextual criticism (such as oral information, writings, photographs, pictures, etc.) help to explore the construction and the procedure of restoration (Hung, 1995), and serve as an aid to the studies of the usage and durability of the materials in the restoration of historical architecture (Dasser, 1990; Wang, 1998). Many clues are lost, because historical architecture is often age-old (Hung, 1995). Under the circumstance, restoration of historical architecture can only be proceeded by restricted pictures, written data and oral information (Shi, 1989). Therefore, computer simulation is employed by scholars to simulate the condition of historical architecture with restricted information after restoration (Potier, 2000). Yet this is only the early stage of computer-aid restoration. The focus of the paper aims at exploring that whether visual simulation of computer can help to investigate the practice of restoration and the estimation and evaluation after restoration.By exploring the restoration of historical architecture (taking the Gigi Train Station destroyed by the earthquake in last September as the operating example), this study aims to establish a complete work on computer visualization, including the concept of restoration, the practice of restoration, and the estimation and evaluation of restoration.This research is to simulate the process of restoration by computer simulation based on visualized media (restricted pictures, restricted written data and restricted oral information) and the specialized experience of historical architects (Potier, 2000). During the process of practicing, communicates with craftsmen repeatedly with some simulated alternatives, and makes the result as the foundation of evaluating and adjusting the simulating process and outcome. In this way we address a suitable and complete process of computer visualization for historical architecture.The significance of this paper is that we are able to control every detail more exactly, and then prevent possible problems during the process of restoration of historical architecture.

title	The challenge of the codification of tacit knowledge in designing and making: a case study of CAD systems in the Hong Kong jewellery industry
source	Automation in Construction 10 (6) (2001) pp. 701-714
summary	Using the separation of designing and making activities in quantity-production systems of the Hong Kong jewellery industry as a case, this paper will show that codifying the tacit knowledge into the CAD systems is becoming deliberately feasible when the tacit knowledge are converted into accessible and applicable formats without losing its distinctive properties. The contextual analysis of the conventional jewellery production systems indicates that the separation of knowledge leads the consequence and the problems of partial representation. In order to study how the tacit-format attributes, which were separately contributed by the jewellery designers and goldsmith, can be extracted, recaptured, recorded, integrated and finally coded into CAD database, a project of scanning a hand-crafted 3D object was initiated and implemented. The successful result of the tested project not only demonstrates the feasibility of codification of tacit knowledge in design representation, but also gives a strong theoretical foundation of the extendibility of both tacit and coded knowledge in a design perspective.

summary	It is the intention of this paper is to construct for the reader a suitable foundation on which to determine a digital design coach. It seeks to define this possibility by examining two ideas. The first is visual thinking, as used by designers in the process of design. The second idea, that of providing students with expert partners for the learning of design is supported by evidence from a variation on protocol analysis (developed by the author) and a related design studio conducted in New Zealand and Jamaica. Using these concepts in relation to recent advances in the development of digital tools the paper proposes what a digital coach may look like.

title	Physical and Digital Media Strategies For Exploring ‘Imagined’ Realities of Space, Skin and Light

summary	This paper will discuss an unconventional methodology for using physical and digital media strategies ina tightly structured framework for the integration of Environmental Control Systems (ECS) principles intoa third year design studio. An interchangeable use of digital media and physical material enabledarchitectural explorations of rich tactile and luminous engagement.The principles that provide the foundation for integrative strategies between a design studio and buildingtechnology course spring from the Bauhaus tradition where a systematic approach to craftsmanship andvisual perception is emphasized. Focusing particularly on color, light, texture and materials, Josef Albersexplored the assemblage of found objects, transforming these materials into unexpected dynamiccompositions. Moholy-Nagy developed a technique called the photogram or camera-less photograph torecord the temporal movements of light. Wassily Kandinsky developed a method of analytical drawingthat breaks a still life composition into diagrammatic forces to express tension and geometry. Theseschematic diagrams provide a method for students to examine and analyze the implications of elementplacements in space (Bermudez, Neiman 1997). Gyorgy Kepes's Language of Vision provides a primerfor learning basic design principles. Kepes argued that the perception of a visual image needs aprocess of organization. According to Kepes, the experience of an image is "a creative act ofintegration". All of these principles provide the framework for the studio investigation.The quarter started with a series of intense short workshops that used an interchangeable use of digitaland physical media to focus on ECS topics such as day lighting, electric lighting, and skin vocabulary tolead students to consider these components as part of their form-making inspiration.In integrating ECS components with the design studio, an nine-step methodology was established toprovide students with a compelling and tangible framework for design:Examples of student work will be presented for the two times this course was offered (2001/02) to showhow exercises were linked to allow for a clear design progression.

title	3D Voxel Grammar of Mangalabas (Goodwill House)

summary	Mangalabas (Goodwill House) is a historic multi-court mansion in Farashganj, Old Dhaka, Bangladesh. The spatial layout combines multiple courtyards, demonstrating how the courtyard is an integral part of traditional Bengali houses and vernacular buildings. During the British colonial period, Mangalabas and many other multi-court mansions were built in Dhaka by combining the native spatial organization of courtyard buildings with imported European elements (Rahmam and Haque, 2001). This typology is unique to Bangladesh and offers configurations with spatial, social, and environmental values that are often missing from contemporary housing in Dhaka. This paper revisits the vernacular essence of Bengali courtyard-based living and presents a 3D voxel-based interpretation of Mangalabas to promote the potential of this building form. The research focuses on inferring shape rules of the volumetric composition to understand the programmatic relations between the courtyards and overall massing. Voxels are used to represent these relationships in a straightforward way and to strategize for the computer implementation of grammar in future work. The current study sets a foundation for understanding this Bengali housing type and the logic of its building form as a basis for designing new housing prototypes that learn from this vernacular.

summary	The idea of the Bauhaus education was born out of the conviction that designs for mass production and modern architecture needed a new fundamental design strategy. Today, seventy-five years later, the modern, basic design pedagogy needs to be revisited, as the impact of the Information Technology Revolution on design practice and education is now extensive. The illustrations and reflections on a modern curriculum for fundamental design and communication presented in this paper are derived from the authors’ introduction of the new media to design studios at UBC and from design practice. In the case of the nascent student of architecture, a different, rudimentary approach is required: one calling for the combining of the modern, basic design agenda with the introduction of the new media. The fundamental digital design pedagogy is young and not fully established. This is a considerable problem, since the practice and learning of architecture today is increasingly aided by and dependent upon digital media. Parallel to the traditional methods, the contemporary student of design is now obliged to engage new and dynamic conditions at the formative stage of his or her education. In the recent past, the computer was considered as just another device, requiring the development of mechanical techniques or skills. While those skills still have to be mastered, more recently in design education and practice, IT has become accepted as MEDIA - not just as a drafting or modeling tool. This process is perhaps due to the rapid dissemination of computing literacy and to the progressive accessibility and ease of use of IT. At UBC, Techniques and the Foundation Studio are introductory courses intended to make students engage the new media in parallel with, and complimentary to, established conventions in design.

title	Self-design and Ontogenetic evolution
source	International Conference on Generative Art
summary	The context and long term goal of the project is to develop design environments in which the computer becomes an active and creative partner in the design process. To try to set-up a system that would enhance the design process by suggesting possibilities, has been preferredto an approach that emphasises optimisation and problem-solving.The work develops around the general concept of morphogenesis, the process of development of a system's form or structure. Besides the obvious example of embryological growth, biological evolution, learning, and societal development can also be considered as morphogenetic processes.The aim is to set a foundation from where latter work can develop in the study of how form unravels, and the implications and possibilities of the utilisation of such processes in design. Some basic principles are established, regarding the idea of Ontogenesis, the study of thedevelopment of organisms, and Epigenesis, the mode Ontogenesis operates.Drawing on D’Arcy Thompson’s ideas and inspired on the models and approaches developed in the recent field of Artificial Life, this work explores the possibilities of using a model based in bone accretion to develop structural systems. The mechanisms by which bone is able toadapt are relatively known and simple, and at the same time they address a sensible problem, such as it is the case of the static performance of a structure. This may seem contradictory with what was mentioned above regarding problem solving. The problem is anyway approached not with the intention of finding optimal solutions, but challenging and creativeones. It is not answers the computer should provide, but questions about the problematic of the design. It is in this context of “problem-worrying” (as opposed to problem solving) that the work has been carried.

summary	Design educators attempt to train the eyes and minds of students to see and comprehend the world around them with the intention of preparing those students to become good designers, critical thinkers and ultimately responsible architects. Over the last eight years we have been developing the digital media curriculum of our architecture program with these fundamental values. We have built digital media use and instruction on the foundation of our program which has historically been based in physical model making. Digital modeling has gradually replaced the capacity of physical models as an analytical and thinking tool, and as a communication and presentation device. The first year of our program provides a foundation and introduction to 2d and 3d design and composition, the second year explores larger buildings and history, the third year explores building systems and structure through design studies of public buildings, fourth year explores urbanism, theory and technology through topic studios and, during the fifth year students complete a capstone project. Digital media and CADD have and are being synchronized with the existing NAAB accredited regimen while also allowing for alternative career options for students. Given our location in the Los Angeles region, many students with a strong background in digital media have gone on to jobs in video game design and the movie industry. Clearly there is much a student of architecture must learn to attain a level of professional competency. A capacity to think visually is one of those skills and is arguably a skill that distinguishes members of the visual arts (including Architecture) from other disciplines. From a web search of information posted by the American Academy of Opthamology, Visual Acuity is defined as an ability to discriminate fine details when looking at something and is often measured with the Snellen Eye Chart (the 20/20 eye test). In the context of this paper visual acuity refers to a subject’s capacity to discriminate useful abstractions in a visual field for the purposes of Visual Thinking- problem solving through seeing (Arnheim, 1969, Laseau 1980, Hoffman 1998). The growing use of digital media and the expanding ability to assemble design ideas and images through point-and-click methods makes the cultivation and development of visual skills all the more important to today’s crop of young architects. The advent of digital media also brings into question the traditional, static 2d methods used to build visual skills in a design education instead of promoting active 3d methods for teaching, learning and developing visual skills. Interactive digital movies provide an excellent platform for promoting visual acuity, and correlating the innate mechanisms of visual perception with the abstractions and notational systems used in professional discourse. In the context of this paper, pedagogy for building visual acuity is being considered with regard to perception of the real world, for example the visual survey of an environment, a site or a street scene and how that visual survey works in conjunction with practice.

title	Exploring the Roles of Exploring the roles of Sketches and Knowledge in the Design Process
source	The University of Sydney, Faculty of Architecture
summary	The needs of computational tools provide the motivation to have a better understanding of the roles of knowledge and sketches in the design process. The inadequacies of current computer-aided conceptual design tools result from our vague comprehension of the nature of the design process. The hypothesis of this study is that the design process involves interlocked and multi-mode processes in which design knowledge and sketches interact with each other to advance the design process. These interactions make current computer-aided design systems unsatisfactory in the conceptual design process. The understanding of these interactions would provide the foundation of more useful computational tools and potentially play a role in developing better pedagogical methods. This research utilized both process-oriented and content-oriented coding schemes to examine different aspects of the design process. Concurrent and retrospective protocols were analyzed to determine their utility in revealing the design processes. Retrospective protocols and the content-oriented coding scheme were selected for design cognition studies in this research, and the procedures of experiments and analyses were described in detail. The results of encoded protocols were presented in terms of segments, levels, and instances. They represented the design process in a way that enabled us to observe the interactions among sketches, knowledge, and different cognitive levels. The examination of the conceptual design process demonstrated its features of interlinked levels and multiple modes; even one snippet of the process contained various modes and sub-processes. The shifting speed of intentions and the vagueness of sketches and functional references were also shown. The study of the meditated roles of the sketches and knowledge in the design process shows the following. First, sketches are the affordances of perceptual and functional instances while designing. Most of the sketches made by designers are multi-functionally bounded. Second, design knowledge plays various roles in the conceptual design process. The ubiquitous designerly way of knowing demonstrates the differences between active developing and passive utilizing design knowledge. Finally, one of the roles of design sketches and knowledge is shown to be the connector among different cognitive levels in the design process. The unpredictability of the design process is demonstrated in the results. Design knowledge provides previously generated solutions for the problem at hand, and design situatedness describes the phenomenon that a designer uses his/her experience to produce novelty and innovation. A method to measure the design innovation through an encoded protocol is proposed based on the concept of situated creativity. The implications for future computer-aided design systems are presented based on the roles of sketches, knowledge, and situatedness in the interlinked and multimode design process. The concept of cognition-oriented CAD is proposed to provide empirical clues to improve current CAD systems.

summary	In Architecture, it is essential to design functional and topologically complicated 3D shapes (i.e. shapes with many holes, columns and handles). In this paper, we present a robust and interactive system for the design of functional and topologically complicated 3D shapes. Users of our system can easily change topology (i.e. they can create and delete holes and handles, connect and disconnect surfaces). Our system also provide smoothing operations (subdivision schemes) to create smooth surfaces. Moreover, the system provides automatic texture mapping during topology and smoothing operations. We also present new design approaches with the new modeling system. The new design approaches include blending surfaces, construction of crusts and opening holes on these crusts.

title	Modeling irregular and complex forms
source	AVOCAAD - ADDED VALUE OF COMPUTER AIDED ARCHITECTURAL DESIGN, Nys Koenraad, Provoost Tom, Verbeke Johan, Verleye Johan (Eds.), (2001) Hogeschool voor Wetenschap en Kunst - Departement Architectuur Sint-Lucas, Campus Brussel, ISBN 80-76101-05-1
summary	Computational technologies provide arguably the first real opportunity architectural design has had for a comprehensive description of built form. With the advent of affordable computer-aided design systems (including drafting, modeling, visualization and simulation tools), architects believe they can be in full control of geometric aspects and, through these, of a wide spectrum of other aspects that are implicit or explicit in the geometric representation. This belief is based primarily on the efficiency and effectiveness of computer systems, ranging from the richness and adaptability of geometric primitives to the utility of geometric representations in simulations of climatic aspects. Such capabilities support attempts to design and construct more irregular or otherwise complex forms. These fall under two main categories: (1) parsing of irregularity into elementary components, and (2) correlation of the form of a building with complex geometric structures.The first category takes advantage of the compactness and flexibility of computational representations in order to analyse the form of a design into basic elements, usually elementary geometric primitives. These are either arranged into simple, unconstrained configurations or related to each other by relationships that define e.g. parametric relative positioning or Boolean combinations. In both cases the result is a reduction of local complexity and an increase of implicit or explicit relationships, including the possibility of hierarchical structures.The second category attempts to correlate built form with constraints that derive usually from construction but can also be morphological. The correlation determines the applicability of complex geometric structures (minimally ruled surfaces) to the description of a design. The product of this application is generally variable in quality, depending upon the designer's grounding in geometry and his ability to integrate constraints from different aspects in the definition of the design's geometry.Both categories represent a potential leap forward but are also equally hampered by the rigidity of the implementation mechanisms upon which they rely heavily. The paper proposes an approach to making these mechanisms subordinate to the cognitive and technical aspects of architectural thinking through fuzzy modeling. This way of modeling involves a combination of (a) canonical forms, (b) tolerances around canonical forms and positions, (c) minimal and maximal values, (d) fuzzy boundaries, and (e) plastic interaction between elements based on the dual principles of local intelligence and autonomy. Fuzzy models come therefore closer to the intuitive manners of sketching, while facilitating transition to precise and complex forms. The paper presents two applications of fuzzy modeling. The first concerns the generation of schematic building layouts, including adaptive control of programmatic requirements. The second is a system for designing stairs that can adapt themselves to changes in their immediate environment through a fuzzy definition of geometric and topological parametrization.

title	Representing design rationale to support innovative design reuse: a minimalist approach
source	Automation in Construction 10 (6) (2001) pp. 663-674
summary	The reuse of previous design knowledge is a potentially important way to improve design efficiency. In practice, however, design reuse is plagued with difficulties, including those associated with the indexing, retrieval, understanding and modification of prior design knowledge. We propose that such difficulties can be ameliorated by employing insights deriving from design-rationale research concerning how best to represent and retrieve design information. We illustrate these insights by describing the development of a design-reuse system that maximizes the benefits of rationale capture and information retrieval whilst minimising the costs to the designer that might arise from disruption to natural design work.

title	Complex shapes in wood: Computer-aided design and manufacture of wood-sandwich roof shells
source	Harvard University
summary	Computer-Aided-Design, Engineering and Manufacturing (CAD/CAE/CAM) technology has changed the way consumer products, automobiles or airplanes are designed and made. The emerging applications for CAD/CAE/CAM technology in architecture, and the way this technology impacts how we design and construct the built environment, are yet unclear. This thesis investigates the relation between advanced digital design tools and the making of physical objects by focusing on an exemplary architectural element—wooden roof shells. The research objective is to expand the scope of architectural design through the application of CAD/CAE/CAM technology rather than to use this technology to streamline existing processes. The thesis develops a specific technical solution that allows the design and manufacture of new types of wooden roof shells. These are complexly shaped multifunctional construction elements that are manufactured off-site. Based on the close connection between digital design tools and the new Computer-Numerically-Controlled manufacturing process the author proposes a theoretical model of shared digital environments for collaborative design in architecture. The proposed manufacturing process treats wood as a modern composite material. Thin wood strips and foams combine into structural sandwich panels that can then be joined into a roof shell. The geometrically complex panels are generated by a combination of subtractive Computer-Numerically-Controlled machining processes and manual work. Infrastructure elements can be embedded into the sandwich build-up in order to enhance the functionality of the roof as a building envelope. Numerical tools are proposed that allow the determination of manufacturing-related parameters in the digital design environment. These inform the architectural and structural design in the early design phases. The digital collaborative design environment is based on a shared parametric solid model and an associated database. This collectively owned, feature-based design model is employed throughout the design and manufacturing process and constitutes the means of concurrent design coordination of all participants. The new manufacturing process for wood/foam sandwich shells is verified by designing and manufacturing prototypes. Design guidelines and a cost estimation are presented as the practical basis for architects and engineers to incorporate new types of roof shells into architectural projects.

title	Integrated Design and Building System for the Provision of Customized Housing: the Case of Post-Earthquake Haiti
source	Computer Aided Architectural Design Futures 2011 [Proceedings of the 14th International Conference on Computer Aided Architectural Design Futures / ISBN 9782874561429] Liege (Belgium) 4-8 July 2011, pp. 247-264.
summary	The paper proposes integrated design and building systems for the provision of sustainable customized housing. It advances previous work by applying a methodology to generate these systems from vernacular precedents. The methodology is based on the use of shape grammars to derive and encode a contemporary system from the precedents. The combined set of rules can be applied to generate housing solutions tailored to specific user and site contexts. The provision of housing to shelter the population affected by the 2010 Haiti earthquake illustrates the application of the methodology. A computer implementation is currently under development in C# using the BIM platform provided by Revit. The world experiences a sharp increase in population and a strong urbanization process. These phenomena call for the development of effective means to solve the resulting housing deficit. The response of the informal sector to the problem, which relies mainly on handcrafted processes, has resulted in an increase of urban slums in many of the big cities, which lack sanitary and spatial conditions. The formal sector has produced monotonous environments based on the idea of mass production that one size fits all, which fails to meet individual and cultural needs. We propose an alternative approach in which mass customization is used to produce planed environments that possess qualities found in historical settlements. Mass customization, a new paradigm emerging due to the technological developments of the last decades, combines the economy of scale of mass production and the aesthetics and functional qualities of customization. Mass customization of housing is defined as the provision of houses that respond to the context in which they are built. The conceptual model for the mass customization of housing used departs from the idea of a housing type, which is the combined result of three systems (Habraken, 1988) -- spatial, building system, and stylistic -- and it includes a design system, a production system, and a computer system (Duarte, 2001). In previous work, this conceptual model was tested by developing a computer system for existing design and building systems (Benr__s and Duarte, 2009). The current work advances it by developing new and original design, building, and computer systems for a particular context. The urgent need to build fast in the aftermath of catastrophes quite often overrides any cultural concerns. As a result, the shelters provided in such circumstances are indistinct and impersonal. However, taking individual and cultural aspects into account might lead to a better identification of the population with their new environment, thereby minimizing the rupture caused in their lives. As the methodology to develop new housing systems is based on the idea of architectural precedents, choosing existing vernacular housing as a precedent permits the incorporation of cultural aspects and facilitates an identification of people with the new housing. In the Haiti case study, we chose as a precedent a housetype called ‚Äúgingerbread houses‚Äù, which includes a wide range of houses from wealthy to very humble ones. Although the proposed design system was inspired by these houses, it was decided to adopt a contemporary take. The methodology to devise the new type was based on two ideas: precedents and transformations in design. In architecture, the use of precedents provides designers with typical solutions for particular problems and it constitutes a departing point for a new design. In our case, the precedent is an existing housetype. It has been shown (Duarte, 2001) that a particular housetype can be encoded by a shape grammar (Stiny, 1980) forming a design system. Studies in shape grammars have shown that the evolution of one style into another can be described as the transformation of one shape grammar into another (Knight, 1994). The used methodology departs takes off from these ideas and it comprises the following steps (Duarte, 2008): (1) Selection of precedents, (2) Derivation of an archetype; (3) Listing of rules; (4) Derivation of designs; (5) Cataloguing of solutions; (6) Derivation of tailored solution.
