A PROPOSAL FOR REUSING SIMULATION MODELS IN THE DESIGNOF PRODUCTION SYSTEMS IN CONSTRUCTION

Abstract: One of the main difficulties of using simulation in the management of construction projects is the fact that developing simulation models is time consuming. One of the possible strategies to cope with this problem is the reuse of an existing model or part of it in other simulation study. Although many authors have pointed out that the unique nature of construction projects leads to the necessity of starting each model from the scratch, the reuse of models for simulating projects of the same market sector seems to be reasonable. This paper aims to assess the main benefits and difficulties of developing reusable simulation models for designing production systems for housing projects. A case study in which a simulation model was developed for supporting that task in a construction company involved in repetitive housing projects is presented. The development of this model took into account the possibility of reusing it in other similar projects of the company in order to reduce the time for doing the simulation study. The main findings are related to the limitations and requirements of reusable models as well as to the implementation of those models in the design of production systems for real construction projects.
