MCDA methods provide a structured framework to support such decisions by handling diverse and sometimes conflicting evaluation criteria. Our study focuses on four widely recognized MCDA methods (AHP, ANP, TOPSIS, ELECT...

In the 1990s, ERP systems become known as an important progress over the preceding Material Requirements Planning (MRP II) systems, and offered improved technology, functionalities, and integration of key business processes. The main architecture of these systems shifted to client/server, while graphical user interfaces (GUIs) were introduced, and thus they became ...
