Process Plan Optimization using a Genetic Algorithm

In this paper we present our ongoing research project GAPO (Genetic AlgorithmProcess Optimization) that focuses on the development of an optimization mod-ule for process plans.GAPO is part of a 4D-Toolbox that conates di erent modules for the 4Dplanning of construction projects. Among other modules, the 4D-Toolbox con-sists of a DES (Discrete Event Simulator) that automatically sequences activi-ties into a network plan
