Bill of materials (BOM): BOM describes the relation of a finished or WIP product with the WIP or raw materials which go in making it. It will describe the ratio in which individual WIP or raw materials go in making one unit of finished or WIP product.
Multilevel BOM: When there is more than one level of BOM in a manufacturing process. In this case at least one WIP parent will consist of a WIP child.
Routing: Routing is the process of defining the route which a finished product and its WIP and raw materials will take through the work centers along the way. There could be many routings for the same finished product or it could be a unique path.
Advanced planning and optimization (APO) software: To differentiate from MPS and APS vendors, some vendors call their software an APO application and state that it takes dynamic inputs for the planning it does. They also state that their software does dynamic planning as compared to the static planning and scheduling feature of MPS software. APO software adjusts the planning and scheduling dynamically on changes in the input parameters. APO software is different from APS software in that it does not do scheduling.
MRP II software: In the late 1980s a new breed of software came in the market which improved on existing MRP software. In MRP, infinite capacity was assumed for any production facility and so requirement of raw material calculation was never right. In MRP II, finite capacity was taken for calculation of raw material requirements.
The bottom line is that whatever terminology used and claims made by vendors, you should be able to judge the merits of these statements and choose the software which will serve your purpose after careful evaluation. At the same time, you should be able to identify some minimum qualifications of the software which will guide you to make a cut mark which will identify whether software is totally useless or has some useful features for you.
