Generation expansion planning is a challenging problem due to its large-scale, long-term, non-linear, and discrete nature of generation unit size. Since the computation revolution, there are several emerging techniques proposed to solve large scale optimization problem. Many of these techniques have been reported to use in generation expansion planning. This paper will describe these emerging o...

In this study, the problem of giving priority to two or more quality chracteristics faced while applying Taguchi Method on multiresponse problems is studied. It was based upon Tong et al.(1997)’s approach on assignment of weights derived from individual experiences. Instead of prioritizing by personal judgments, Analytic Hierarchy Process (AHP) and Analytic Network Process (ANP) methods were us...

The analytic hierarchy process (AHP) is a structured technique for dealing with complex decisionmaking and is already used to solve many group decision problems. This paper used the CauchySchwarz inequality to improve the AHP algorithm that was developed by Escobar et al. (2004). They provided an upper bound for the group geometric consistency index in order to prove that the group geometric co...

Supply Chain Management is an integrated approach to increase the effectiveness of the logistics chain by improving cooperation between the players in the chain. Supplier selection is one of the most crucial activities performed by organizations because of its strategic importance. Supplier selection is a multi-objective problem involving both quantitative and qualitative criteria the paper pro...

the findings indicate that among the main factors affecting job stress the psycho-social, physical and environmental factors are prior to the other factors. also amongst the psychosocial factors, lack of career promotion opportunities with 0.222 has the most weight and a lack of accountability of the management about the employees' concerns with 0.036 has the least weight; amongst the phys...
