Abstract

Thanks to its simplicity and cost-effectiveness, discrete event simulation is preferred for construction simulation, and the issue of how to model the production capacity of a continuous plant by using discrete event simulation is addressed. A plant of continuous nature relies on a material-handling mechanism (such as conveyor or pipeline) to continuously convey material delivered in truckloads to a designated activity location at the site. In contrast with discrete resources commonly encountered and matched in construction (such as a truck, an excavator, and a crane), a buffer is the hallmark of a continuous plant (such as unloading container); and one or multiple feeder resources (trucks) can be simultaneously processed subject to the production capacity of the plant. With a concrete pump example, we discuss the potential pitfall of simplifying a continuous plant as one discrete resource entity. Then, we formalize an approximate method for representing a continuous plant with N discrete resource entities in simulation of a predominantly discrete operations system. We also describe two practical applications: (1) modeling the production capacity of a magnetic separation plant in iron mining operations; (2) modeling the passing capacity of an urban road section in microtunneling and pipe-jacking operations. In conclusion, the proposed method adds to the usefulness and flexibility of a discrete simulation methodology in modeling complicated construction systems.
