The emergence of the global economy has transformed the interdepartmental nature of a transnational enterprise into a highly collaborative oriented team. This transformation enables the enterprise to lower its transaction and coordination costs and increase its competitive advantage in the global market. This study investigates such a so-called intra-supply chain system that exists in present-d...

This study attempts to determine the optimal production run time for an economic production quantity (EPQ) model with a Poisson breakdown rate, the rework of nonconforming items, and multi-delivery of finished products. It is assumed that nonconforming items can be randomly produced and repaired through a rework process added at the end of the production process. Production equipment is subject...

POMS 22 nd Annual Conference Reno, Nevada, U.S.A. April 29 to May 2, 2011 Abstract: MTS-MTO system is suitable where standard modules are shared by various finished products through divergent finalization. The system can satisfy product variety by taking advantage of flexibility of MTO, but its performance is lowered when the capacity is constrained. One way of dealing with the problem without ...

This paper concerns problem formulation and solution procedure for inventory planning with Markov decision process models. Using data collected from a large paper manufacturer, we develop inventory policies for the finished products. To incorporate both variability and regularity of the system into mathematical formulation, we analyze probabilistic distribution of the demand, explore its connec...

We analyze a rationale for official authorization of patient dumping in the prospective payment policy framework. We show that when the insurer designs the healthcare payment policy to let hospitals dump high-cost patients, there is a trade-off between the disutility of dumped patients (changes in hospitals' rent extraction due to low-severity patients) and the shift in the level of cost reduct...

This paper presents and quantifies some of the opportunities of E-business tools to material flow effectiveness. The study was developed at a Brazilian drug distribution system. Results are based on comparing historical data against the simulation of an alternative, which manages the distribution process employing an E-business solution embedded with simple replenishment methods to coordinate t...

the marked shift in the patterns of drug use in iran, from opium smoking to injecting drug use, has led to serious health-related outcomes. this study was designed to explore characteristics of people who inject drugs (pwid) in tehran, iran. nine hundred and four pwid were recruited from treatment and harm reduction facilities, as well as drug user hangouts in public areas in tehran. participan...

Medical technology assessment, which traditionally has involved evaluating whether a technology was safe and effective, has been expanded in recent years to include consideration of cost-effectiveness. While most analysts and policymakers would agree that cost-effectiveness is, in principle, a worthy goal, actually using such a standard in coverage decisions is much more difficult. This Comment...
