DECISION-MAKING PROCESS TECHNIQUES USED IN THE OPTIMIZATION OF CONSTRUCTION PROJECTS

Abstract

It is desirable that the construction projects can be completed in the most appropriate manner at the desired time, cost or other purposes. If any of these requests are solely aimed, the appropriate project parameters can be determined and the results such as the optimal time or cost can be determined after an optimization process. If more than one goal is to be achieved at the same time, the decision making process becomes more difficult. In this case, rather than a single final result, multiple results can be obtained. A number of techniques are used to optimize both time and cost. In this study, the techniques proposed for this purpose in the literature have been examined and some of these techniques have been applied to the construction projects considered as time-cost problem. Also, the TLBO algorithm, popular in recent years, has been the preferred in the solution of the multi-objective optimization problem. Construction project business activities which are taken into account as a time-cost problem in the literature are examined as numerical examples. A computer program is developed to realize the time-cost trade-off problem by using MATLAB.
