||In our work on enterprise engineering we are concerned with developing a fiamework andmethodology for modeling real world enterprise. Our primary concern is that the resulting enterprisemodels should give insight into the operation of today's enterprise, and allow systematic studies topredict likely effects of proposed changes.Last year, at the CIB W78 workshop in Helsinki, we presented an initial overview of CAESAR, anarchitecture for enterprise modeling in the AEC industry. CAESAR addresses the Objectives,Product, Process and Organization (OPPO) aspects of enterprise, and covers the complete life-cycle,including requirements specification, conceptual design, detailed engineering, approval, fabrication/installation, operation, maintenance, and decommissioning.This year we apply the CAESAR framework to develop a simple model of a hydraulic system for oilproduction facilities. Such hydraulic systems are used for a variety of control tasks on offshoreplatforms, where different users have a range of different functional and operational requirements.We use the hydraulic system model to derive measures of coordination load, which may be used asinput to simulate project execution as a set of information processing tasks. The Virtual Design TeamOT) discrete event simulator is used to predict changes in development schedule and life-cycle costdue to changes in scheduling and execution of design and development.
