APPLICATION OF MULTI-TECHNIQUE IN PROJECT PLANNING TO SOLVE TIME-COST TRADE-OFF PROBLEM

Abstract: One of the most important problems in project management is the time-cost trade-off problem (TCTP) that must be taken into consideration during project planning and control process through the use of suitable planning techniques. This study presented a model aims to solve (TCTP) using crashing as a traditional project planning technique and concurrency technique with activities partitioning in addition to new suggested technique that mixes between the two techniques and named as Concurrency-with Partitioning and Crashing Technique (CPCT). The model focuses on minimizing project time and cost and it is applied on an adopted case study. The results show that the suggested (CPCT) produces the best results for the two objectives compared to other applied techniques.

Keywords: project planning; time-cost trade-off problem; multi-technique; crashing technique; concurrency technique.
