We consider a single-period assortment planning and inventory management problem for a retailer, using a locational choice model to represent consumer demand. We first determine the optimal variety, product location, and inventory decisions under static substitution, and show that the optimal assortment consists of products equally spaced out such that there is no substitution among them regard...

This paper is on production planning and inventory control in systems where manufacturing and remanufacturing operations occur simultaneously. Typical for these hybrid systems is, that both the output of the manufacturing process and the output of the remanufacturing process can be used to fulfil customer demands. Here, we consider a relatively simple hybrid system, related to a single componen...

The management of production and inventory control associated activities in remanufacturing production system has received attention by practitioners in the last two decades. This is due to the increased productivity, limited supply of virgin materials, stringent environmental requirements for product disposal and treatment as well as substatial change in global sustainability regulations. In o...

This paper is motivated by the inventory planning issues faced by a manufacturer of a digital projector. The seller faces demand from two sources: new demand, and demand to replace failed items under warranty. We model this setting as a multi-period single product inventory problem where the new demand in different periods are independent and the demand for replacing failed items under warranty...

This paper addresses a non-linear optimization model by integrating production planning and inventory control in the automotive industry at the strategic and operational level. In order to provide an effective modeling, we developed a framework to integrate manufacturing system and suppliers within an automotive supply chain network. The numerical experiments demonstrate the efficiency of the p...

The critical importance of integrating production, distribution, and inventory (PDI) operations has long been recognized by top management of many companies. Now. using (he laiest advances in Managemenl Science modeling and solution technology, an integruied computer-based PDI system has saved approximately $18 million dollars during its first three years of implemenlalion for a major national ...

Procurement is one of the major activities in the Manufacturing Resource Planning (MRP II), which is closely coupled with inventory management. Any improvement in this area will have a direct impact on the performance of the entire supply chain. Auction mechanism can be a successful procurement method when there are several potential suppliers available. In this work we consider a single-period...
