An optimization model for precast project planning using group concepts

Abstract

Construction projects adopting precast pieces are feasible to reduce project uucertainties over components which are produced in factories, stored in factories or external sites, and transported with trucks to satisfy installation demand. In order to create project plans, planners should arrange available resources and select appropriate ways to produce, store, and transport components. This study adopts several group ideas to organize an overall precast project. Based on these group concepts, an optimization model and a recursive procedure are proposed. Appropriate molds and zones can be determined in the recursive procedure, and the project plan can be created through the optimized project cost. An example experiment is demonstrated to explain the feasibility of the proposed model and group concepts. © 2010 The Operations Research Society of Japan.
