These problems are characterized by a large number of solutions that may satisfy the basic conditions of the problem. The method most often employed to determine the optimum solution to such problems is linear programming. Unfortunately, linear programming techniques are generally not applicable to the type of problems where all constraints are not explicitly defined, e.g.., where the demand is estimated or known only with a given probability. Problems of maximization of profits or social benefits in the allocation of available resources or facilities continuously arise in planning and architecture, where the amount of available or potential resources (utilities, housing units, social services, etc.> is explicitly known, but where the demand is not. This paper demonstrates how one may formulate problems with demands that are not precisely known, are projected, or are estimated with some given probability. In addition to the general statement of such problems, several specific applications of the method for both planning and architectural problems are presented. The examples and solutions given involve: I) the distribution of municipal recreation equipment and facilities among several neighborhood parks each with different demands for the different facilities; 2) the allocation of city services to new communities with various estimated demands. The method presented in this paper also permits the formulation of such problems Into the standard linear programming format for solution by computer.

The method described provides the designer with the means for making judgments as to locational desirability even with limited data availability. The procedure also raises the level of decision parameter selection above the "local" level to include "universal" or "global" interrelationships. The means for utilizing macro-level data and information to make micro-level decision is demonstrated. An actual case study for housing site suitability near Chicago is presented to illustrate the approach. The merits of the technique over previous approaches and the problem of designer "judgment" in computer-aided methods is also discussed.

This class of problem, if linear, can be readily solved using classical stochastic linear programming. It is shown that the problem may be formulated as a stochastic dynamic program. A problem of designing the HVAC subsystem is formulated and solved as a dynamic program. Comparisons are made between the two methods. It is shown that dynamic programming is the more powerful method both in terms of obtaining the solution and in its post-optimality analysis. It is suggested that dynamic programming is a suitable technique for a wide range of building and architectural design problems.

This paper describes a system of computer programs which were developed in an attempt to pull together current design methodologies. In summary, the paper describes the general system and discusses the basic assumptions and concepts implemented within it. Each method presented is described and executed with the same specific design problem for the purpose of demonstration and comparison.

While the process of design implies a fit between the user demands or requirements and system conditions and constraints, the lack of accurate information about these user requirements and demands alters the quality of the final product. Since we generally neglect to consider that many of the design problem parameters are not completely known or deterministic, but are, in fact, estimated or stochastic, we often fail to recognize that our final design may not have completely met the actual user needs or demands. Failure to have achieved the user needs may result in systems that either cannot perform adequately under severe operating conditions or which may cause physical damage or harm. Therefore, most design procedures and design codes provide an adequate level of safety to ...
