- Abstract
- The dynamic nature of today's construction industry compels contractors and owners to seek strategies to improve performance. Intensive local and foreign competition for construction contracts, new alliances between owners and contractors, and in general, changing approaches to construction characterize ongoing industry changes. Under these conditions, it is difficult to predict implications of individual or combined construction execution strategies on project performance. Understanding these implications is key to successfully meeting the new challenges facing construction in the 90's and on into the twenty-first century. The objective of the study is: To develop a new methodology for capturing and formalizing construction experts' knowledge in such a way that a general model can be developed to analyze project performance. In order to address shortcomings in available methodologies, several desirable characteristics of the methodology were established: (a) The evaluation of project performance should be addressed by utilizing multiple performance criteria and a flexible weighting procedure for evaluation. (b) The methodology should evaluate different execution strategies, individually and combined. (c) The modeling approach should include procedures to disaggregate the problem and capture expertise from construction experts at different levels. (d) Uncertainties and cause-effect relationships among model variables should be an explicit part of the structure. These characteristics are all incorporated into the proposed modeling methodology and are discussed in this Source Document.
