A New Approach to Simulation of Heavy Construction Operations
To support the utilization of discrete-event simulation in the analysis and planning of heavy construction operations, this research investigation has established a framework for a more simplified simulation environment. This framework is a resource operation cycle-based simulation modeling approach using an objectoriented information system to support project managers. This approach allows for reusable simulation modeling elements that build various resource (operation cycle) models. The prototype system, KMOS (Knowledge-embedded MQdularized Simulation system), provides a modularized resource model-building environment, step-by-step guidance to the user, flexibility in modeling, and easy control of complex construction operations. It includes an information system which provides guidance in the overall simulation procedure based on embedded knowledge. This paper will outline the major components of KMOS, as well as results of simulations performed using stochastic data captured from concrete paving operations.
