In multiobjective optimization problem, a substantial number of solutions generated along the Pareto front are unacceptable to the decision maker. In this paper, we propose a variation of the concept of Pareto dominance by using a penalty based Multi Objective Genetic Algorithm which attempts to obtain the nondominated set of Pareto solutions within the acceptable region for decision maker. A Relenting...
Suppliers evaluation and selection is one of the most critical activities of purchasing management in a supply chain, because of the key role of suppliers' performance in achieving the objectives. And it is a multi-criteria decision-making in which the objectives are not equally important. Supplier evaluation and selection decisions are complicated by the fact that various criteria must be considered...
Consolidation of IT resources is a frequently cited task for IT decision makers, aiming to remove redundancy and thereby to cut costs. However, while economically motivated, the methods described in the literature rarely address costs directly. Instead, the focus often remains on purely IT-related considerations. In this paper, IT consolidation is addressed fro man operations research perspective,...
Bilevel-programming techniques are developed to handle decentralized problems with two-level decision makers, which are leaders and followers, who may have more than one objective to achieve. This paper proposes a λ-cut and goal-programming-based algorithm to solve fuzzy-linear multiple-objective bilevel (FLMOB) decision problems. First, based on the definition of a distance measure between two fuzzy...
Effective and efficient selection of projects in strategy-focused environments is extremely vital and consisted of complex processes for Information and communication technology (ICT) sectors to maintain organizational sustainability. In order to decide which of the proposed projects should be selected, various conflicting criteria must be considered. Even though there are many studies available to...
For environmentally oriented business decision-making, the linear mixed integer optimisation model of the business process with included possibilities for an integrated approach to environmental management is presented. Using this model as a scenario in decision-making simulations, managers can recognize and evaluate the consequences of their decisions on business performance and on the environment...
