Object-oriented models for material requirements planning systems.

The Material Requirement Planning System (MRP) is a key module in the Enterprise Resources Planning (ERP) systems. Finding better ways of developing systems leads to a robust MRP system and provides prototypes which can be expanded to other modules of the ERP systems. This thesis will provide an object-oriented model of a MRP system which was created and presented by using the Object Modeling Technique (OMT). The model consisted of three parts, the object model, dynamic model, and functional model. An innovative way to handle the static bill of materials (BOM) data with a more flexible dynamic item class was developed. To demonstrate the flexibility, extendability, and reusability of the object-oriented MRP model, two major business change scenarios were applied to the model. Minor changes to the design were required to accommodate major changes on the functionality of the MRP system.
