Group Preference Aggregation Based on ELECTRE Methods for ERP System Selection

The ability of enterprise information systems, such as enterprise resource planning (ERP), manufacturing executive systems (MES) and customer relation management (CRM), to improve production and business performance are demanding more attention from enterprises, since increase in competitive advantages is a goal to be reached. Integration of all the information flowing through a company is a key characteristic of ERP systems. Enterprise systems are not developed in-house and so, in order to implement an ERP project successfully, organizations must purchase ERP systems which can be aligned with their needs. In a group decision context where all opinions and preferences must be taken into account, choosing the most suitable alternative may be a hard work. In this study, a group preference aggregation approach based on a combination of ELECTRE II and ELECTRE IV method is presented within the context of ERP project selection.
