This article proposed mathematical models for multistage and multiproduct system when the demand and lead time is known and constant. However, the quality and resources breakdown uncertainties glued with the models. Secondly, the component commonality notion is integrated with the models. The models are validated with real data from a Malaysian company and randomly generated numerical scheme. The material requirement schedule in stable and known situations is generated. The outcomes are compared with the same from MRP II and live primary data collected from the floor. It is found that the two schedules converge. However, the proposed models are bearing additional information of the location where to be available the parts in a time frame. The effects of commonality on cost, capacity and requirement schedule under the quality and breakdown troubles are discussed. It is observed that use of common parts in manufacturing is always better over the non-commonality scenario in terms of production cost and capacity requirements.
