Model for Expressing Logic of ERP System and its Application in maintenance

This article seeks to establish a logical connection between the basic concepts and create a framework for better understanding of ERP and its implementation. Also, the paper tries to be understandable and gives a better description of the Enterprise Resource Planning system with non-technical method in ERP software packets by showing of a page of operation in maintenance unit.Since most of managers know and deal with 4P business model and its components and they can communicate with it easily, the primary structure of the ERP system is derived from this model. ERP system is divided into four main components: 1. Software, 2. Customer points of view, 3. Change management, and 4. Internal processes of system.Methodology is another component which is involved in abovementioned four components for providing integration/unity and implementation in organized method. Maintenance planning is used for continuity of production with manpower to help keeping the equipment in normal conditions. As equipment is considered as the main sources of the organization, their maintenance would be important and this could be done easily by using this software system. Consequently, we can develop the better understanding of ERP complexity in system and processes which contribute to performance by creating conceptual model and features of different elements.
