Optimisation by Evaluation in the Appraisal of Buildings

The paper describes the application of optimisation techniques based on cost benefit analysis. The cost of provision, maintenance and 'failure'-to-provide are used. The use of indifference sets and production functions for design decisions is demonstrated. There is a model of the design process which relates these techniques to those of analysis and design synthesis. The relationship of parts of the system to the whole, and of constraints, is examined in this context.
