Abstract

The main purpose of this research is to use a decision approach in prioritizing strategy choice for SWOT matrix analysis. This research was done in 2010, in Frab Co. which works in the field of installation of water and energy projects in Tehran. Based on the nature of the research, its statistical society was managers and experts of different units of the organization. The members of this team include the managing director, management of human resources, director of planning and project control, inspection and quality control manager, financial and administrative management and engineering management and deputy of projects affairs. The present research in terms of purpose is an applied research; it is also considered as a descriptive research. In this research for determining important weight, fuzzy analytic network process was used. The fuzzy method used was Chang’s extent analysis (EA) method. Excel software was used to calculate analytic network process by using extent analysis method for determination of important weights, and MATLAB software was used to get the final results of the study. Research results showed that when dependence exists among SWOT (strengths, weaknesses, opportunities and threats) factors, this dependence could change weight and priority of strategy alternative, and eventually WO (weaknesses- opportunities) strategy with the final weight of 0.317 was selected as the best strategy. Key words: Strategic planning, SWOT matrix, analytic network process, fuzzy analytic hierarchy process, Chang’s extent analysis method, triangular fuzzy numbers.
