        1 - Supplier selection with the approach of combining Fuzzy Delphi Analytic Hierarchy Process (FDAHP) and Grey VIKOR methods
        Mohammad Mahdi Mozaffari

        The supplier selection is one of the most important issues in supply chain management discipline and it is regarded as an effective factor for companies to survive in the competitive environment. Selecting the best supplier among various suppliers, considering a mixture of criteria that are sometimes in conflict, makes it a complicated multi-criteria decision making problem. On the other hand, supplier selection is highly dependent on the assessments of decision makers and according to the environmental dynamics and incomplete information available to decision makers, they are faced with some uncertainty in their assessments. The purpose of this paper is to present a model of multi-criteria decision making under uncertainty by using concepts of fuzzy and grey theories in order to select the optimal supplier. In this research, first, the weights of supplier selection criteria are determined by using fuzzy Delphi and analytic hierarchy process, then suppliers are ranked by using Grey VIKOR which is a newly developed approach in the field of multi-criteria decision making under uncertainty Manuscript profile

        A lot of methodologies for evaluation of the lean transformation have been proposed in the literature, but just a few of them explicit relations among the components of the lean enterprise transformation, with focusing on the priority and identification of the relative weight of each element on the lean transformation have been considered. Therefore, we try to quantify those relations in this study. So, to structural investigate the relationships among the elements, a model is proposed that presents a novel comprehensive insight to the lean transformation process. This study proposed an analytic modeling approach in the lean enterprise transformation to identify the weights of the elements. The goal is to operationalize the highly qualitative relationships among the lean transformation components. In this paper 32 effective factors in lean enterprise transformation, identified as "sub sub criterion" were grouped into eight categories classified as "sub criterion". These eight sub criteria classified through 3 criteria in the higher level which are “organizational asset development”, “quick adaptation to markets and competitive superiority acquisition” and “supply and distribution network optimization These three criteria were proposed as the major criteria involved in "delivery value maximizing", and ultimately, the value maximizing recognized as the main target of the lean transformation in companies. Fuzzy DEMATEL technique and fuzzy analytic network process modeling are used to determine the relationships and the relative weights of each component and then with fuzzy VIKOR method, 25 identified solutions related to conceptual model were ranked for implementing the lean transformation which regard the organizational purposes and the weights of the end level parameters of the conceptual model in a proposal framework. The present evaluating lean enterprise transformation is a comprehensive model that can be applied to different production industries. This model also was investigated in automative parts industry.

        Paper manufacturing industry is one of the prominent and impactful industries in countries and societies. Leak of knowledge, awareness, information and etc. is affiliate to the existence of paper and without it, there is no chance of saving and recording the information. Each year a significant amount of paper is being produced and consumed in the world and the turnover of this industry is significant. In this research the focus is on paper industry and the providers of this service and we are seeking to prioritize the decisions based on merging of fuzzy model of second type with decision making of several complex dynamic indexes. With VIKOR in paper industry. First of all, 5 important decisions have been identified by the expertise in paper industry that includes 1) An attempt to include technology and new machines 2)Investigating on new products and diversification of products 3) Educating employees and managers 4) Organizing technical production, storage and managing the employers 5) Suitable pricing and advertising to attract new inside and outside consumers Also 6 criterions have been proposed to evaluate these decisions For evaluating the decisions, we have used the fuzzy VIKOR approach of type 2 and after going through research stages, decision number 1 and 2 gained the most priority.

        According to importance of subject, the aim of this study is to evaluate and rank factors of intellectual capital and organization entrepreneurship that aims to improve the performance of corporation. Therefore, after reviewing the literature and interviews with professors and coil industry experts, intellectual capital, organization entrepreneurship and firm performance factors were identified. After designing and distributing questionnaires among coil industry experts, priority and importance of each of these factors with using Fuzzy TOPSIS, FAHP, vikor, ELECTRE were evaluated. According to the results of the above methods in cases not compatible with each other, to achieve the overall ranking of integration methods (POSET) that includes: rating average method, Borda method, Copeland method and integration phase (POSET) has been used. The results obtained from FAHP method, according to the company's performance improvement indicate that the net profit is the most important subcategory of the factors affecting corporate performance improvement; competitive advantages, customer retention, market value of the company; innovation capacity and volume of transaction are at ranking highest respectively. The results obtained from FAHP method indicate that organization entrepreneurship is more significant than intellectual capital of the factors affecting corporate performance improvement. Different Ratings have offered for intellectual capital and sub-scales of Human capital, Structural Capital, Relational Capital, Innovation Capital and Customer Capital factors. To reach a consensus, it was used in the ranking of integration (POSET) method and based on integration (POSET) method is most important factors of intellectual capital that helps to improve company performance improvement in order of importance include: Human capital, Structural Capital, Relational Capital, Innovation Capital, Customer Capital factors and also, the most important factors of Human capital, Structural Capital, Relational Capital, Innovation Capital, Customer Capital regarding to company performance improvement in order of importance Include: Leadership ability, Employees’ competence, Employees’ experience, Employees’ creativity, Individual-level knowledge, Customer satisfaction, Motivation of the personnel, Customer loyalty, Employees’ attitude, Organizational structure, Staff’s experience, Organizational learning, Marketing capability, Databases, Management system, Use of knowledge, Strategically values, Operation process, Information system, Corporate culture, Brand value, Mission-vision, Relationship with suppliers and competitors, Size of organization, Innovation culture, Relationship with other organization, Market intensity, Company lifecycle, Customer appropriateness, Innovation mechanism and Innovation achievements. based on integration (POSET) method is most important factors of organization entrepreneurship that helps to improve company performance improvement in order of importance include: structural factors, underlying factors, behavioral factors and also, the most important factors of structural factors, underlying factors, behavioral factors regarding to company performance improvement in order of importance Include: Entrepreneur organization structure, Entrepreneur organization strategy.
