Interval Valued Multi Objective Critical Path Problems and Their Solution by Risk Attitude Parameter

Abstract

This paper contains risk attitude parameter, exponential and linear membership function based method to obtain the critical path that optimized multi objectives, in multi objective project network. Four objectives–total price, time period, worth and threat of the project activities are to be optimized in project organization. In this paper, a model is formulated for selection of critical path in project network consisting all criteria as grey numbers. To solve this multi-criteria project management problem, risk attitude parameters utilized with fuzzy programming technique. A numerical illustration is also described to validate functioning of the proposed approach. To analyze the performance of the offered method, comparison is done with closely related grey multi objective critical path selection method.
