Six sigma may be named as a powerful and comprehensive management tool which is necessary in order to bring changes in organization and to make conformity with customer needs. Despite of other quality approaches, six sigma is not only a method, but it contains a vision, a goal and a symbol. Beside the six sigma, symmetrical valuation method is interpreted as a tool to collect strategy. This sys...

This paper presents a method for solving the multicriteria group decision making problem in an uncertain linguistic environment. To ensure an effective aggregation of the uncertain linguistic variables in multicriteria group decision making for adequately modeling the uncertainty and imprecision of the decision making process, an uncertain linguistic Choquet integral operator is proposed. A met...

Supplier selection is a multiattribute decision making (MADM) problem which contains both qualitative and quantitative factors. Supplier selection has vital importance for most companies. The aim of this paper is to provide an AHP based analytical tool for decision support enabling an effective multicriteria supplier selection process in an air conditioner seller firm under fuzziness. In this a...

In this paper a novel handoff decision algorithm, namely multicriteria handoff decision algorithm (MDA), for the virtual cell layout based mobile subsystem of the next generation tactical communications systems is introduced. In this algorithm, handoff decision metrics are received signal strength measurements from the access points, soft capacities of the access points, and relative directions...

Multicriteria decision making (MCDM) has found many applications in both public and private sector organizations. MCDM is both an approach and a set of techniques, with the goal of providing an overall ordering of options, from the most preferred to the least preferred option. The set of MCDM techniques are implemented in selecting the vendors and 3PL service providers. Supplier selection is a ...

Development and use of remediation technologies for contaminated soils and water progresses at a very fast pace and thus a large number of cleanup alternatives emerge. The selection of the most appropriate Remediation technology for the given site must be based on many, usually conflicting, criteria. To successfully apply all these criteria a multicriteria decision support system (DSS) is neede...

Applying evolutionary computation (EC) to multicriteria decision making addresses two diicult problems: (1) searching intractably large and complex spaces and (2) deciding among multiple objectives. Both of these problems are open areas of research, but relatively little work has been done on the COMBINED problem of searching large spaces to meet multiple objectives. While multicriteria decisio...

Industrial location problems belong to the scope of multicriteria decision making (MCDM) given the high number of attributes to be considered in its planning and analysis. This work deals with a problem with four potential sites and five influential subjective criteria. A panel of experts related to the problem makes a fuzzy valuation of these attributes allowing to capture the uncertainty inhe...

Until now, decision under uncertainty and multicriteria decision making have been investigated separately and almost independently, although there is a close link between both fields. Decision theory is also closely related to measurement theory. Besides, it is well known that additive representations in decision making are not sufficient to avoid paradoxes such as Ellsberg’s paradox. Therefore...

In this paper, we propose arrow decision logic (ADL), which combines the main features of decision logic and arrow logic. Decision logic represents and reasons about knowledge extracted from decision tables based on rough set theory, while arrow logic is the basic modal logic of arrows. The semantic models of ADL are pairwise comparison tables, which are useful in rough set-based multicriteria ...
