The branch and bound principle has long been established as an effective computational tool for solving mixed integer linear programming problems. This paper investigates the computational feasibility of branch and bound methods in solving convex nonlinear integer programming problems. The...

product reliability is impacted by the use of two different types of after-sales maintenance support contracts: time and … of incentives that establish why product reliability may increase or decrease under PBC. We build a two-stage econometric … effect of PBC on product reliability. The estimation of our model indicates that product reliability is higher by 25 …

As companies outsource more product design and manufacturing activities to other members of the supply chain, improving end-product quality has become an endeavor extending beyond the boundaries of the firms' in-house process capabilities. In this paper, we discuss two contractual agreements by...

Classical Economic Manufacturing Quantity (EMQ) models have usually ignored the possibility of process deterioration and the existence of defective items in the production lot. Moreover, the use of machine inspection for maintenance and restoration purposes has not been considered. On the other...

This paper deals with the determination of optimal inspection policies when inspections have the potential of being harmful to the device under consideration. The device operates throughout a number of periods and in each period is subject to failure. Failure of the device is directly...

Consider the problem of minimizing the expected cost of identifying the state of a coherent system (as "functioning" or "failed"). The system is composed of components (that either fail or work), and only individual components can be tested. Efficient algorithms are presented for some special...

In this paper we investigate importance sampling techniques for the simulation of Markovian systems with highly reliable components. The need for simulation arises because the state space of such systems is typically huge, making numerical computation inefficient. Naive simulation is inefficient...
