Time-Cost Trade-Off Analysis using IP Formulations

Abstract

Mathematical approaches adopted in construction management literature convert CPM network and time-cost relationships of the project into constraints and objective functions. Based on literature survey the (Integer Programming) IP-Solver approach for project crashing is still the most reliable approach to analyzing DTCTP. In this dissertation work Integer programming technique has been employed to address the time cost trade off because of the easy availability of high speed computers.A computer code in C++ has been developed and an open source solver has been employed in the computer program to solve the defined time cost trade off through integer programming. A detail background for Mathematical Programming Models and concerned formulation has been highlighted in the following section.
