Application of backward chaining, "fuzzy logic," and the management of information to procurement of facility systems/services

This paper introduces the research work of the Performance Based Studies Research Group (PBSRG), the Alliance of Construction Excellence (ACE), and the Del E. Webb School of Construction (DEWSC) to apply a new evaluation/delivery mechanism for construction systems to increase performance of the construction systems. The research is based on "fuzzy thinking" and the management of information. Concepts utilized include "backward chaining" solution methodology, and a relative distancing model to procure the best available facility systems. Participants in the program include general contractors, Job Order Contractors, mechanical contractors, roofing contractors, material suppliers and manufacturers, and facility owners and managers from Motorola, Honeywell, Morrison Knudson, IBM, and from other major facilities in the Phoenix metropolitan area.
