Applying Rough Set Theory and Grey Theory in Multi-attribute Decision Making Methods for the Evaluation and Selection of ERP Systems

Enterprise resource planning systems by facilitation and integration of organizations’ operations as well as leveraging the organization's operations and business activities has become an important competitive advantage for organizations. Although the appropriate choose of an ERP system can greatly contribute to the success of the organization, inappropriate selection of ERP also can lead to irreparable damages and costs. Therefore, in this study we have tried to use a multi-attribute decision-making model to evaluate and select the most appropriate ERP system. Since decision makers turn to “uncertain preferences” to evaluate the criteria and alternatives, applying Rough Set and the Gray Set theories in the context of multi-attribute decision-making models seems more logical and consistent. The findings indicate that the “total cost” a sub-criteria of product characteristics and “system technical capabilities” a sub-criteria of system requirements are the most significant criteria and the “A6” is the most significant alternative

Using an Integrated Approach QFD, FAHP and VIKOR to Select an Appropriate ERP System

Enterprise resource planning systems (ERP) for facilitating the operation of organizations and integration of the process of business data are an important competitive advantage for organizations. To the successful implementation of an ERP system is essential to choose a system that can be aligned with the needs of the organization. Therefore, a proper decision-making approach for the selection of an ERP system is required so that take into accounts the needs and characteristics of the ERP system and also the interaction between them. So in this study, an integrated decision-making framework for the selection of ERP systems based on the concept of QFD, fuzzy analytic hierarchy process and Vikor provided. The framework makes the needs of the organization and also features of ERP system. To validate the model, the model is applied in a case. The results of this study show that among of the criteria, the cost and system performance criteria are the most important and sixth supplier is the most proper supplier.
