Solution of Extended Multi-Objective Portfolio Selection Problem in Uncertain Environment Using Weighted Tchebycheff Method

In this paper, a mathematical model for an extended multi-objective portfolio selection (EMOPS) problem is explored with liquidity considered as another objective function besides the risk and return. The mathematically formulated in uncertain environment. concerned uncertainty dealt by employing fuzzy numbers matrix While EMOPS converted into corresponding deterministic case based on α—level sets of numbers, weighted Tchebycheff method implemented defining relative weights ideal targets. merit suggested applicability many real-world situations. At end, some numerical illustration exhibited utility problem. Finally, it concluded that simple to learn implement real-life situations decision maker.
