performance of a supply chain highly depends on its suppliers and therefore, appropriate selection of them is of great importance. this paper presents an integrated model of an mcdm method and a mathematical programming in order to select suppliers and determine lot sizes in the supply chain. the proposed framework comprises two main sub-models; the qualitative sub-model seeks to evaluate the s...

Super MD Tile Factory is an individual business that engaged in the production of tiles small quantities. One products produced Mantili tile with make to stock and order systems. Defective process cannot be completely avoided. The company sets a tolerance for defective production, which 4.44%, but practice can reach 8%. Types defects such as porous, cracked, broken, cracked tiles, charred.The w...

Traditional economic manufacturing quantity (EMQ) model addressed that the perfect production for product. However, there possibly exists the defective product in the manufacturing process. Hence, it is necessary to include the quality cost in the EMQ model. In this paper, we propose a modified EMQ model with quality loss and inventory cost. By solving the modified EMQ model, we can obtain the ...

The silicon die and copper lead-frame in IC packaging are bonded by die attach adhesive, and the quality of the interface is a critical issue in the reliability testing of IC packaging and during the manufacturing process. Common defects such as crack and delamination can be detected using C-mode ultrasonic microscopy method with sufficient confidence. However, weak interface due to weak adhesi...

In statistical quality control, product acceptance determination is an important problem for producer and consumer. In practical, particularly more than one quality characteristic must be simultaneously considered to improve the product quality because of the product design. In this article, we investigate the lot sentencing problem for normally distributed process with one-sided specification ...
