Object–Oriented Enterprise Modeling and Simulation of AEC Projects

Christensen, Lars Chr. / Christiansen, Tore R. / Jin, Yan / Kunz, John / Levitt, Raymond E.

In this paper we describe an object–oriented framework for developing enterprise models of Architecture, Engineering, Construction projects, and a methodology for formalizing these models such that they can be used for discrete event simulation of information processing and coordination in project execution. The simulation results can be used to predict the probable effects of carrying out proposed changes in planning and managing projects.

In our enterprise modeling framework we represent engineering design projects in terms of deliverables (requirements and solutions), plans (activities and process relations), and organization (participants and organizational relations). The resulting project model is the starting point for identifying coordination requirements between project team participants. Our methodology uses matrix techniques derived from qualtiy function deployment (QFD) to identify interactions between project requirements and solutions and calculate measures of product complexity. We then describe information flow between project activities in a similar matrix and calculate measures of process uncertainty. Finally, we identify the responsibilities of project team members and use a matrix to point out organizational interdependencies.

We apply our framework and methodology to model and simulate engineering design for a major extension of an electrical power substation. Our simulation results demonstrate how project performance is contingent on the fit between the project policies and the objectives and preferences of the project team.
