Facility location selection is a decision problem that takes into consideration both qualitative and quantitative factors and also is one of the most important strategic decisions affecting organizations in terms of business success. Fundamentally, it comprises evaluating a group of alternative sites on the basis of multiple criteria. In this context when alternatives and factors are multitudinous, multi-criteria decision making methods are being used for successful decisions. In this paper the decision problem is exemplified by applying on a part of a project for a call center site selection by using one of the multi-criteria decision-making methods, namely hierarchy grey relational analysis, based on application of analytic hierarchy process (AHP) and grey relational analysis (GRA) methods. The goal of the selection is to determine the most appropriate location among the alternatives.Nine cities given as alternatives are evaluated and compared against human resources, economic and regional conditions including fourteen sub-criteria.
Turkey is an important logistics transport center between Asia, The Middle East and Europe. If this position is evaluated correctly, it will be a big contribution to the economy of the country by increasing the market share. In order to provide and sustain logistic quality in an increasingly competitive environment, it should be ensured that logistic services are performed more effectively and efficiently via analyzing faults/problems in detail and eliminating root causes of these. In logistics sector, especially in the case of cold chain logistics involving the transport of perishable products such as food, medicine, chemicals, etc., the rejects/ fines constitute on a large-scale rate. Companies, in the case of deliveries that are outside the expectations of the companies or contrary to their contracts, they either return the goods or take delivery by punishing. In this study, the causes of these logistics/delivery factors, effecting negatively the country’s economy were researched, and suggested important solutions by analyzed with the Theory of Constraints - Thinking Processes approach. These proposals for the characteristic solutions for cold chain logistics, if applied in the institutions and companies concerned with the logistic sector in the whole country, it is expected that will obtain the savings of the costs coming from penalty/reject applications in the country’s economy, and beyond this it is expected that will get the additional earnings from the increased market share by increasing the customer satisfaction.
