Resources Suainability Planning Model Using Hierarchical Approach for Construction Project

Abstract

Within the early stages of construction project planning, resources restrictions are often neglected. Usually this leads to cost and schedule overruns. Moreover, the adoption of resources restricted project planning may lead to a complex optimization problem. Thus engineers should focus on resources-based project planning for more schedule efficiency. Nevertheless, the integration with traditional methods as the PERT (program evaluation and review technique) or the CPM (critical path method), can improve schedule reliability significantly in project failures due to insufficient resource allocation. Potential applications of resource-restricted project scheduling for construction project planning are revealed with some suggestions on the integration of this approach into traditional planning methods are made. For overlapping both, traditional planning methods as well as resource-based planning models, knowledge transferred from production planning to project planning by applying a hierarchical approach. Analyses of multi planning problems in construction projects are undertaken and the roles of the generalized resource-restricted project scheduling model and selected extensions within construction project planning are discussed
