Abstract: Discrete event simulation is getting more attention as a tool for allocating construction resources. However, its usage is limited because it requires intensive knowledge in conducting simulation studies. Phases of a simulation study are constructing a representative model for the process, executing the model, and experimenting with the model. Using traditional simulation (i.e. Discrete Event Monte Carlo Simulation), the intellectual activities in conducting a simulation study are accomplished by the user who should possess a sophisticated knowledge in conducting such analysis. This paper presents an alternate approach to traditional practice in performing simulation studies. The approach is called Goal Driven Simulation System (GDSS). A simulation study using GDSS is considered as a problem solving approach in which the user specifies a model for a construction process and performance criteria for construction resources as well as a simulation goal (e.g. hauling 400 m3/h) to be achieved by conducting the simulation study. GDSS allocates appropriate construction resources that satisfy the goal and meet the performance criteria through alternating between the execution and the experiment phases.
