Extending enterprise modeling beyond engineering - a life cycle model of hydraulic systems

Abstract: In our work on enterprise engineering we are concerned with developing a fiamework and methodology for modeling real world enterprise. Our primary concern is that the resulting enterprise models should give insight into the operation of today's enterprise, and allow systematic studies to predict likely effects of proposed changes. Last year, at the CIB W78 workshop in Helsinki, we presented an initial overview of CAESAR, an architecture 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 oil production facilities. Such hydraulic systems are used for a variety of control tasks on offshore platforms, 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 as input to simulate project execution as a set of information processing tasks. The Virtual Design Team OT) discrete event simulator is used to predict changes in development schedule and life-cycle cost due to changes in scheduling and execution of design and development.

MODELLING MULTI-CRITERIA DECISION ANALYSIS FOR BENCHMARKING MANAGEMENT PRACTICES IN PROJECT MANAGEMENT

Abstract: The link between management practices and worker’s motivations impacting construction productivity is being considered as significant among the research community. This research aimed to identify and analyse the underlying attributes impacting construction productivity from the site management perspective. This research presents a framework designed to analyse and quantify the relative relevance of different drivers in the determination of productivity levels and the degree of effectiveness of potential opportunities for improving performance of overall projects. Owing to the complexity of construction projects and underlying conflicting drivers influencing higher worker’s productivity, the Analytical Hierarchy Process (AHP) is employed to deal with interdependent relationships within a multi-criteria decision-making model. In the analytical approach, the large unstructured decision parameters are identified first and then are broken down into the manageable and measurable components using a top down hierarchical structure. This paper demonstrates an example to illustrate how to empirically analyse and prioritise a set of influencing parameters as selection criteria in devising appropriate management practices to ensure higher productivity vis-a_-vis optimum performance of projects.

Towards Systems Integration Theory in Megaprojects: A System-of-Systems Framework

Abstract: Megaprojects are large-scale, complex projects composed of various interconnected constituents. Recent research suggests that effective systems integration is one of the major challenges affecting the success of their delivery and that we hence need new taxonomies to characterise and evaluate integration in this context. This paper draws on and contributes to a growing literature on systems integration in megaprojects by proposing a formalized framework for characterization and evaluation of integration between constituents of megaprojects. In this study, megaprojects are conceptualized as systems-of-systems (SoSs). Based on this conceptualization, a SoS framework towards a systems integration theory in megaproject SoSs is proposed. The proposed framework includes two aspects. The first articulates the different dimensions of systems integration. It identifies the types of integration; focuses of integration; integration at different levels; and integration in different phases in megaproject SoSs. The second aspect is related to the indicators of systems integration. Seven indicators are discussed for evaluating the degree of integration in megaprojects. The proposed SoS framework provides a theoretical basis for future research on systems integration in megaprojects and can be used as a guide for developing corresponding empirical studies.
