Abstract
One of the biggest challenges facing the companies and entrepreneurs is development of new winning products. The new challenges demand decreasing costs, better customer satisfaction, reducing development time, on time delivery, production of quality products, optimizing design specifications, and improving revenues. The customers may not know what they want or be reluctant to commit and may change their requirements mid-stream in the development process. Rapidly altering products requirements has resulted in companies resorting to different tools and techniques for addressing the customer needs. Multi-criteria approach may offer valuable tools to handle complex situations with multiple objectives, incorporating the imprecise and uncertain information. Evaluation and selection of a refrigerant is a complex decision-making problem involves many multiple conflicting criteria. This paper mainly focuses to multiple criteria decision approach for modeling and solving problem using TOPSIS method. Further designing of the model for TOPSIS is done using program written in C. Application of the TOPSIS method is used to enhance the COP (coefficient of performance) of refrigeration system by selecting refrigerant on the basis of available criteria. Also the results are compared by using SDI tool software.
