A study of the EPQ model using fuzzy AHP when flaw of the products or unreliable machineries exists

The methods to solve production problems usually assume the production process for the machines completely reliable and the products are perfect. This has the quite big difference with the production system in the reality. The enterprise is often facing many uncertainties in the production planning choice. Such as unreliability of the machineries, the quality differences, the finished product slight defect problems, and imperfect internal processes caused possible shortages and so on. The passed related researches usually emphasis a single issue or consideration, or make the model too complicated to use. Therefore, this study is to investigate the possible impact of economic production quantity (EPQ) model decision-making factor. Use EPQ model to explore the most economical choice production cost factor based on the uncertainties may exists.
