Optimal Testing Procedures for Special Structures of Coherent Systems

Ben-Dov, Yosi - In: Management Science 27 (1981) 12, pp. 1410-1420

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...

Importance Sampling for the Simulation of Highly Reliable Markovian Systems

Shahabuddin, Perwez - In: Management Science 40 (1994) 3, pp. 333-352

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...

On Optimal Replacement Policies

Assaf, D.; Levikson, B. - In: Management Science 28 (1982) 11, pp. 1304-1312

A system (e.g., a car) must operate for the next t time units. A certain component (e.g., a battery) must be replaced whenever it fails, as it is essential for the operation of the system. There are several types of components differing only in price and life distribution. The problem of...

Quality Improvement Incentives and Product Recall Cost Sharing Contracts

Chao, Gary H.; Iravani, Seyed M. R.; Savaskan, R. Canan - In: Management Science 55 (2009) 7, pp. 1122-1138

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...

Simultaneous Determination of Production Cycle and Inspection Schedules in a Production System

Lee, Hau L.; Rosenblatt, Meir J. - In: Management Science 33 (1987) 9, pp. 1125-1136

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...

A Hazardous-Inspection Model

Butler, David A. - In: Management Science 25 (1979) 1, pp. 79-89

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...

Reliability modeling of demand response considering uncertainty of customer behavior

Kwag, Hyung-Geun; Kim, Jin-O - In: Applied Energy 122 (2014) C, pp. 24-33

Demand response (DR) has been considered as a generation alternative to improve the reliability indices of the system … potentially bring new problems associated with maintaining a reliable supply. In this paper, a reliability model of the demand … availability and unavailability are associated with the simple two-state model. The reliability model is generalized by a multi …
