RESOURCES SUSTAINABILITY PLANNING MODEL USING HIERARCHICAL APPROACH FOR CONSTRUCTION PROJECT

Abstract

Within the early stages of construction project planning, resourcesrestrictions are often neglected. Usually this leads to cost and schedule overruns. Moreover,the adoption of resources restricted project planning may lead to a complex optimizationproblem. Thus engineers should focus on resources-based project planning for more scheduleefficiency. Nevertheless, the integration with traditional methods as the PERT (programevaluation and review technique) or the CPM (critical path method), can improve schedulereliability significantly in project failures due to insufficient resource allocation. Potentialapplications of resource-restricted project scheduling for construction project planning arerevealed with some suggestions on the integration of this approach into traditional planningmethods are made. For overlapping both, traditional planning methods as well as resourcebasedplanning models, knowledge transferred from production planning to project planningby applying a hierarchical approach. Analyses of multi planning problems in constructionprojects are undertaken and the roles of the generalized resource-restricted project schedulingmodel and selected extensions within construction project planning are discussed.
