The Supplier Selection Problem (SSP) consists of analyzing and measuring the performance of a set of suppliers in order to rank and select them for improving the competitiveness of the whole supply system. As many conflicting factors should be taken into account in the analysis, the problem can be tackled using multi-criteria models and methods. In this work a careful scrutiny of the papers app...

introduction: balanced scorecard (bsc) is regarded as one of the successful tools in performance measurement. however, it neither absolutely nor comparatively provides the weight of each perspective and indicators related to each perspective. in this study, we applied a fuzzy analytical hierarchy process (fahp) to weight the perspectives and bsc indicators in hospital. methods: this applied, de...

the aim of this study was to develop an optimal sustainable forest plantation based on goal programming and analytic hierarchy process (ahp) methods. this study was carried out in guilan province, north of iran. first of all, the ecological capability of the study area for plantation establishment/maintenance was evaluated based on multi-factor method and specific ecological makhdoum model by m...

throughout life cycle of oil production wells, it is imperative to have production optimization and real response time to rapid changes of well conditions and more understanding of subsurface otherwise it is the matter of expenditure losing. smart well capabilities meet aforementioned issues. however there is a key concern in managers' mind that they have limited budget and several fields' docu...

this research conducted in order to prioritize the effective criteria on development of medicinal plants cultivation in north khorasan province using analytical hierarchy process (ahp) and delphi methods. for this purpose, a list of effective factors offered to delphi group. analysis of delphi process showed that among 23 offered factors 19 factors, had greater impact on development of medicina...

the final goal of all dairy cow raising systems in the world is to use the available capacities and the cooperation of other sectors in order to solve the problems and issues, such as the limitations in time, man power and financial resources, for providing a complete answer. therefore, the need for optimization of cow raising systems by prioritization of measures and plans is the most obvious ...
