DEVELOPMENT OF A NETWORK ANALYSIS PROGRAM USING CRITICAL PATH METHOD
Abstract
ABSTRACT
The time-cost trade off problem (TCTP) is an important issue in the scheduling of projects it is often possible to expedite the completion of certain activities by increasing the budget. This paper develops a new approach for the discrete TCP (DTCP) in program evaluation and review technique network of project management, in which activities have multimode discrete cost functions and activity durations are normally distributed. More over, the first application of the ant colony system (ACS) is applied to the stochastic DTCTP, solving it as a non linear zero-one problem. To illustrate the suggested approach, a numerical example is discussed and an overall efficiency measure is developed to set the ACS parameters so as to reach more accurate result with less computation time. The results obtained from the computation study demonstrate the effectiveness f the suggested approach for the DTCTP.
