Modeling a Conceptual Framework for Owner-Contractor Relationship and Time-Cost Trade-Off Using Fuzzy Logic Techniques

This paper proposes a conceptual framework forowner- contractor relationship and time-cost trade-off analysisof construction project control system using fuzzy logicapproach. Construction projects require a well-definedstarting point and well-defined finish point with accurateresource allocation to avoid any cost overrun. During thelifecycle of the project, different problems can appear. Themost important ones are delay and construction cost overrunduring the executing phase of the project. To avoid that, aneffective planning system with effective control technique is acrucial issue. The main objectives of this research are todevelop and design a conceptual framework that may be aguide for the contractor and the owner for controlling theconstruction projects. The results show that a good conceptualframework need to start with breaking down the project inconjunction with analyzing the cost and time to have both thecontractor and the owner the better and less risk in having agood proposal in time, cost and quality. However the finalframework show that a need for continuous feedback from theowner to the contractor during the planning process and alsocan help in designing and developing a proposal that satisfyboth the contractor and the owner in terms in time, cost andquality. Risk assessment should be one of the main factors thatshould be considered during all steps in monitoring, planningand controlling the project. Finally a simulation has been doneusing the Fuzzy logic approach to validate the conceptualframework)
