ESOURCE CONSTRAINT PROBLEMS FACED ON CONSTRUCTION PROJECTS AND PROPOSAL FOR BALKAN CONSTRUCTION SECTOR

Abstract

Considerıng project plans to affect cash flows of construction projects will be aimednecessarily to use constraint resources providing a maximum financial benefit as aresearch study. Resource-constrained project scheduling is the most appropriatemethod of planning of a project activities use limited resources without destroyingtheir precedence relationships. The aim of this study is to propose a solution to theproblem of the time value of cash flows under resource-constrained projectscheduling. For this purpose, cash flows and their net present value graphics of asolid waste transfer station construction project were established under differentscenarios. Dividing into phases of time-based scheduling and resource-constrainedscheduling were compared giving some examples for model and algorithmsanalyzing cash flows and maximum net present value problems, time basedscheduling and resource-based scheduling of a solid waste transfer stationconstruction project was formed. The generated planning were evaluated underdifferent scenarios and examined for different objective functions. The dataobtained from the each scenario were presented with their graphics. These datawere described by comparing the results obtained. The initiation of this study iscaused importantly by the applications of irregular and unmethodicalunderstanding of planning techniques applied in Turkish construction sector. As aresult of this study, scenarios using constrained resources forced less the budgetlimits, but it was observed that it formed lower net present value than the scenarioswhich do not have resource constrained in equal time intervals. This study isproposed to discuss Balkan construction sector projects with the problems of thetime values of cash flows under resource-constrained scheduling.
