Globalization of business and competitiveness in manufacturing has forced companies to improve their manufacturing facilities to respond to market requirements. Machine tool evaluation involves an essential decision using imprecise and vague information, and plays a major role to improve the productivity and flexibility in manufacturing. The aim of this study is to present an integrated approac...

Multi-attribute analysis is a useful tool in many economical, managerial, constructional, etc. problems. The accuracy of performance measures in COPRAS (The multi-attribute COmplex PRoportional ASsessment of alternatives) method is usually assumed to be accurate. This method assumes direct and proportional dependence of the weight and utility degree of investigated versions on a system of attri...

Global economic competition has spurred the manufacturing sector to improve and invest in modern equipment to satisfy the needs of the market. In particular, machine tool selection is the most important problem; it plays a primary role in the improvement of productivity and flexibility in the manufacturing environment and involves the imprecise, vague and uncertain information. This paper prese...

Cross-border E-commerce has grown exponentially in the past decade in global market. To gain global competition in product-convergent markets, China’s over 200 thousands cross-border E-commerce businesses have focused more on the service and cost control of supply chain downstream. In this study, we analyse three strategic cost control measures, summarise ten evaluation criteria for cost and de...

The aim of the current research is to measure objective congruence (incongruence) of the results obtained in a process of multiple criteria analysis when applying different MCDM methods. The methodology for evaluation of ranking results is developed on the ground of a case study of the redevelopment of derelict buildings as well as on composed experimental tasks. Fuzzified COPRAS, TOPSIS and VI...

Machine tool selection is a very complex procedure. It involves deep analysis of various factors affecting functioning and performance. CNC machine tool selection is also a such kind of problem[5]. Objective of this study is to perform various MCDM methods for selecting most appropriate machine tool. AHP method is used to calculate the weights of various criteria[10] . The numerical problem con...

Article history: Received July 28, 2012 Accepted November 27, 2012 Available online December 1 2012 Today global warming is on the rise and the natural resources are getting consumed at a faster rate. Power consumption has increased many folds to cater the human need. Thus renewable energy resources are the only option available at this juncture. Wind energy is one of the renewable energy. Loca...

Selecting the right truck tractor is critical for logistics companies involved in road freight transportation. The fact that having many conflicting criteria and alternatives complicates decision-making process decision-makers (DMs). determination of are effective selection tractors then evaluation main objectives this study. In context, a hybrid Multi-Criteria Decision-Making (MCDM) model comp...

Some machine part failures have often occurred in areas of components where the strength was lowest, especially at its weld region. Presence voids weldments or joints greatly reduces quality weldment. To prevent these defects, a proper optimum selection process parameters is highly encouraged to achieve an acceptable mechanical property. The Complex Proportional Assessment (COPRAS) method appli...

Background: Coal production and marketing enterprises can significantly reduce transportation costs improve their competitiveness by choosing appropriate road companies. Methods: Based on this, a trapezoidal fuzzy SWARA-COPRAS method is proposed to select coal The SWARA used determine the index weight of ranking companies determined using COPRAS method. Results: Taking enterprise in Hubei, Chin...
