Design Decision Support Systems Items discussed previously Brief: statement what is required by client. Analysis: understanding the brief. Site: characteristics of the location. Type: information about the building type. Other sources: inspiration and information. Representation: how to depict the design. Evaluation: understanding progress of design.

Design Decision Support Systems Theory: Basic Design Cycle There are many different kinds of activities when designing: analysing, creating design, making representations, evaluation, etc. The order of these activities is not pre- established. Yet every design process has all these activities! This leads to the Basic Design Cycle…

Design Decision Support Systems Elements of BDC Function Analysis Criteria Synthesis Provisional design Simulation Expected properties Value of the design Decision Evaluation Approved design On the basis of the expected properties, the design can be evaluated. This is explicitly based on the criteria established before.

Design Decision Support Systems Elements of BDC Function Analysis Criteria Synthesis Provisional design Simulation Expected properties Value of the design Decision Evaluation Approved design Based on the evaluation and value of the design, the designer decides whether to continue designing, or if the design is finished

Design Decision Support Systems Theory: Basic Design Cycle The BDC does not strictly prescribe the order of activities! The BDC distinguishes the various activities and documents in the design process. The BDC identifies the general relations between the activities and documents. But any of these activities must have been at least once in a design process.

Design Decision Support Systems What to do? Analyse your complete design process in terms of BDC: –Use your time-stamped drawings and texts as a basis. –Describe per drawing/text what kind of document it is (function, criteria, provisional design, expected properties, value of the design, or approved design) and from which activity it is the result (analysis, synthesis, simulation, evaluation, or decision).

Design Decision Support Systems Tips ‘n Tricks Do not remake your design just because you are now analysing it. Use whatever you have now. There is no described format for each of the documents or activities; it can be a word, thought, or a large drawing or lengthy document. Work through your process in the same order as you designed the house.
