Abstract: | We describe the development and successful implementation of a decision support system now being used by several leading firms
in the architecture and space planning industries. The system, which we call SPDS (spatial programming design system) has
the following characteristics: (i) user-friendly convenience features permitting architects and space planners to operate
the system without being experienced programmers; (ii) interactive capabilities allowing the user to control and to manipulate
relevant parameters, orchestrating conditions to which his or her intuition provides valuable input; (iii) informative and
understandable graphics, providing visual displays of interconnections that the computer itself treats in a more abstract
methematical form; (iv) convenient ways to change configurations, and to carry out ‘what if’ analyses calling on the system’s
decision support capabilities; (v) a collection of new methods, invisible to the user, capable of generating good solutions
to the mathematical programming problems that underlie each major design component. These new methods succeed in generating
high quality solutions to a collection of complex discrete, highly nonlinear problems. While these problems could only be
solved in hours, or not at all, with previously existing software, the new methods obtain answers in seconds to minutes on
a minicomputer. Major users, including Dalton, Dalton, Newport, and Marshal Erdwin, report numerous advantages of the system
over traditional architectural design methods. |
