Fuzzy grey relation method for multiple criteria decision-making problems

Combining the concepts of fuzzy set theory, entropy, ideal, and grey relation analysis, a fuzzy grey relation method for multiple criteria decision-making problems is proposed. First, triangular fuzzy numbers and linguistic values characterized by triangular fuzzy numbers are used to evaluate the importance weights of all criteria and the superiority of all alternatives versus various criteria above the alternative level. Then, the concept of entropy is utilized to solve the adjusted integration weight of all objective criteria above the alternative level. Furthermore, using the concepts of ideal, the grey ration grades of various alternatives versus ideal solution are ranked to determine the best alternative. Finally, a numerical example of selecting most appropriate company to build a new highway is used to demonstrate the applicability of proposed method. The study results show that this method is an effective means for tackling MCDM problems in fuzzy and grey environments.

Locating the competitive relation of global logistics hub using quantitative SWOT analytical method

Evaluating the competitive position of location develops global logistics hub (GLH) is a multiple criteria decision-making (MCDM) problem and it is important for governor to implement suitable strategies appropriate its environment. SWOT analysis is very important in the process of strategic formulation. Under many conditions, the evaluative criteria (indicators) are mixed with quantitative/qualitative values and the values for qualitative criteria are often imprecisely defined for decision-makers. A quantified SWOT analytical method, that integrates the method of fuzzy Analytic Hierarchy Process (AHP) method, was proposed to provide more detailed and quantified data for SWOT environmental analysis to assess the competitive relation for locations develop different types’ GLH in Pacific–Asian region. Integrating the concept of Grand Strategy Matrix (GSM), a suitable competing strategy could be suggested for location developing GLH in accordance with its competitive position.     

Towards right-shoring: a framework for off-and re-shoring decision making

Location decisions are crucial for manufacturing plants. While current research mainly stresses the cost considerations of location decisions, this research focusses on a more comprehensive decision-making process. Based on analyzing the motivations for off-and re-shoring, we present a decision-making framework which will help companies to ‘right-shore’. Through a multiple case study approach in the aeronautics industry, an industry known for its technical complexity and innovative nature, we will validate and broaden our initial decision-making framework based on literature. While analyzing this framework, it became apparent that the main motivation for offshoring in the aeronautic industry is far from being restricted to cost-cutting considerations. More specific, companies in this industry are willing to develop sustainable commercial partnerships in emerging countries to benefit from new capacities and resources. In the same vein, re-shoring decisions are grounded on long-term perspectives and are carefully balanced. While providing a comprehensive framework for offshoring and re-shoring decisions, our framework enables companies to make better informed decisions for choosing the right location for their plants.

Optimal plant location and air quality management under indivisibilities and economies of scale

The implications of indivisibilities and economies of scale on the optimal location of industrial plants and on the optimal choice of their pollution abatement technologies under given air quality standards are examined. Various optimization models, accounting for abatement, land development and plant relocation costs, as well as for locational economies of scale, are developed, using the integer and mixed-integer linear programming framework. A method for computing taxes and subsidies leading the system to the optimal pattern of decisions under decentralized decision-making is proposed. Finally, an application of the approach with real data of the Haifa region is implemented, illustrating the utility of the approach for environmental management.     

Optimizing Location Among Three Countries Under Exchange Rate Uncertainty: Applying Real Options

This investigation extends the Batch Process Model [Lin et al. (2002). Journal of management and system 9: 173–196] from two productive locations between two countries to establish a decision valuation model for selecting the optimal location of three productive locations among three countries, respectively. A general form with the first order of degree homothetic production functions is also considered by the rule of decision-making in the proposed model. The firm is risk neutral and this study adopts the real options approach for valuing the behavior of the transferable location among three countries. Furthermore, using Dynamic programming and Lagrange Multiplies for a continuous-Time Model Optimization Problem to get a closed form solution of the threshold value, sensitivity analysis, and some characteristic strategies of the operating method for batch process model among three countries are sought, providing for another way of thinking.
