In a competitive environment, effective management of production and inventory decisions is critical to maintain an efficient and balanced flow of the supply chain system. Manufacturing companies across supply chains have recognised that inventories can be managed more effectively through increased collaboration and better coordination. In practice...

KEYWORDS ABSTRACT Inventory-Routing; Covering problem; Selective Vehicle-Routing; Mobile Blood Collection Supplying of blood and its products are some of the most challenging issues in the healthcare system since blood is an extremely perishable and vital good, and blood donation is a voluntary work. In this paper, a two-stage stochastic selective-...

This paper proposes to design an X-bar control chart through an integrated three-stage multi-objective optimization process. The multi-objective formulation reflects the needs of X-bar control chart designing process's multiple objectives, e.g., the expected time that the process remains in statistical control status, the type I error, and the dete...

Process capability indices (PCIs) are widely used to determine whether a production process is capable of producing items within a pre-specified tolerance. In most real cases, the process data are autocorrelated which deteriorate the traditional assumption of independency. Thus, a new robust capability index with unbiased estimator (NCpa) is applie...

Process planning and production scheduling play important roles in manufacturing systems. In this paper a multi-objective mixed integer linear programming model is presented for the integrated planning and scheduling of multi-product. The aim is to find a set of high-quality trade-off solutions. This is a combinatorial optimization problem with sub...
