Production system design in construction using simulation to support decision-making

Abstract

This research study proposes a model for designing the production systems of construction projects based on the use of discrete event simulation as a tool to support decision-making, using as a starting point a previously developed model. Constructive research was the methodological approach adopted in this study, in which innovative construction projects are devised in order to solve different types of relevant practical problems. The study was divided into four phases: (a) literature review; (b) exploratory phase, in which a simulation software was selected and an exploratory study was carried out; (c) development phase, which involved four empirical studies, in which the proposed model was devised and evaluated; and (d) analysis and reflection phase, in which the role of production system design was analysed, as well the main benefits and difficulties of using simulation to design production systems. A strategy for reusing models was also proposed in order to reduce the duration of the simulation models. The proposed model for Production System Design has two overlapping phases: a deterministic phase and a dynamic phase, in which simulation models are developed and scenarios are tested to support decision-making.
