The model has deterministic and imprecise parameters which follows triangular possibility distributions. The brass casting APP model can not always be solved by using common approaches used in the literature. Therefore a mathematical model is presented for solving this problem. In the proposed model, the Lai and Hwang-s fuzzy ranking concept is relaxed by using one constraint instead of three constraints. An application of the brass casting APP model in a brass factory shows that the proposed model successfully solves the multi-blend problem in casting process and determines the optimal raw material purchasing policies.}, journal = {International Journal of Industrial and Manufacturing Engineering}, volume = {3}, number = {4}, year = {2009}, pages = {345 - 349}, ee = {https://publications.waset.org/pdf/10723}, url = {https://publications.waset.org/vol/28}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 28, 2009}, }
