Yayın A Decision Making Model for the Evaluation of Supply Chain Execution and Management Systems(ATLANTIS PRESS, 2013) Apak, Sinan; Vayvay, Ozalp; Feyzioglu, Orhan; Apak, SinanA Supply Chain Execution and Management (SCEM) system is an enterprise application that integrates all of the necessary supply chain functions into a single system. These functions range from common ones such as warehouse and transportation management to less known ones such as demand management. In order to execute and manage the supply chain processes successfully, organisations need a comprehensive evaluation approach to determine the most suitable system. The evaluation of an SCEM system involves numerous decision making criteria. Moreover, it is usually characterised with uncertainty and vagueness since it is very difficult to rate SCEM system alternatives with exact terms. To cope with this problem, a fuzzy logic-based approach is developed in this study. This approach main integrates the Fuzzy Analytic Hierarchy Process to weight the decision criteria and the Fuzzy Technique for Order Preference by Similarity to Ideal Solution to rate alternatives. A real life example is provided to demonstrate the capability of the proposed approach.Yayın A new systematic approach for warehouse management system evaluation(UNIV OSIJEK, TECH FAC, 2016) Apak, Sinan; Tozan, Hakan; Vayvay, OzalpWarehouse management is one of the most important legs in supply chain operations and production management. To support that warehouse execution, a warehouse management system is required. Many warehouses have used various methods to handle this difficult and time consuming evaluation process. The purpose of this paper is to provide a decision support model to make a careful evaluation of warehouse management system. Purchasing an appropriate warehouse management system in a supply value chain is not an easy decision making and is related to fuzziness and uncertainty, which should be considered as a large number of complex factors in multiple evaluation criteria. A Fuzzy Multi Criteria Decision Making approach is adopted to effectively evaluate warehouse management systems. To provide a practical guidance for other companies a real life framework is presented with an application.
