Nowadays, improving and upgrading quality of products and services is one the main reason for outgoing the competitors and penetration into markets. This article is about the deficiency of the traditional FMEA, and introduces a new method based on estimated costs fuzzy FMEA and utility values. In the proposed method a new fuzzy RPN is defined. A pair wise comparison among Severity, Occurrence a...

in last decades, the skillful planning of land resources has become a major issue for rural development. the development of cultivated areas becomes gradually impossible due to ever increasing population growth and urban development. fuzzy logic is preferred to boolean logic for land evaluation, because fuzzy techniques lead to estimate for land use suitability on a continuous scale and can the...

The fossil resource consumption, which is scarce for the solution of increasing energy demand problem as population increases, replaced by consumption renewable resources. Solar from sources type with highest potential on earth. maximization efficiency to be taken solar possible correct selection location. decision decide more than one criterion multiple alternatives a very difficult problem. T...

This paper proposes a modified software quality evaluation method based on products comparison, judging by user perceived satisfaction in terms of quality. The focused evaluation model is formulated on the bases of the ISO 9126 quality model as a generally accepted standard and ISO 12119 for software package, and of the Analytic Hierarchy Process (AHP) which is appropriate for comparing paired ...

Now-a-days software manufacturing companies usually try to capture market share with rapid software development. Actually the development of high quality software products can decrease cost by reducing rework and increasing productivity. For that, reason selection of software projects is an important task. Several factors come into consideration while selection of proper project for a specified...

The conveyor system plays a vital role in improving the performance of flexible manufacturing cells (FMCs). The conveyor selection problem involves the evaluation of a set of potential alternatives based on qualitative and quantitative criteria. This paper presents an integrated multi-criteria decision making (MCDM) model of a fuzzy AHP (analytic hierarchy process) and fuzzy ARAS (additive rati...

Any decision is closely linked to the quality and availability of information. Innovative methodologies are proposed to help decisions based on imperfect information provided by more or less reliable and conflicting sources in uncertain context. These methods combine new uncertainty theories and multicriteria decision making. The ER-MCDA methodology associates the Analytic Hierarchy Process (AH...

Landfill location selection is a multi-criteria decision problem and has a strategic importance for many regions. The conventional methods for landfill location selection are insufficient in dealing with the vague or imprecise nature of linguistic assessment. To resolve this problem, fuzzy multi-criteria decision-making methods are proposed. The aim of this paper is to use fuzzy TODIM (the acro...

In this paper, we consider the problem of bus selection for public transportation using a hybrid multicriteria decision making approach. The problem includes several conflicting factors which are economic, social, and technological factors. The integrated approach brings the flexibility of fuzzy AHP and simplicity of fuzzy VIKOR methodology together. To demonstrate the applicability of the meth...
