Reliability and Inventory in a Production-Storage System

Meyer, Robert R.; Rothkopf, Michael H.; Smith, Stephen A. - In: Management Science 25 (1979) 8, pp. 799-807

The reliability of a single stage production-storage system in meeting a constant known demand is analyzed. This system …

(m,T) Group Maintenance Policies

Ritchken, Peter; Wilson, John G. - In: Management Science 36 (1990) 5, pp. 632-639

A model that recognizes the advantages of coordinated group maintenance planning is established. The maintenance policy that is investigated calls for group maintenance to be conducted at time T or upon m failures, whichever comes first. This policy combines the best features of the well-known...

Transition Times: Distributions Arising from Time Heterogeneous Poisson Processes

Lenk, Peter J.; Rao, Ambar G. - In: Management Science 41 (1995) 7, pp. 1117-1129

The units of a heterogeneous population are subjected to shocks. A unit fails, or more generally, undergoes a change of state after a sufficient number of shocks. The shocks for a particular unit are assumed to arrive according to a time heterogeneous Poisson process. The time to a change of...

A Dynamic Model for Posttraumatic Stress Disorder Among U.S. Troops in Operation Iraqi Freedom

Atkinson, Michael P.; Guetz, Adam; Wein, Lawrence M. - In: Management Science 55 (2009) 9, pp. 1454-1468

We develop a dynamic model in which Operation Iraqi Freedom (OIF) servicemembers incur a random amount of combat stress during each month of deployment, develop posttraumatic stress disorder (PTSD) if their cumulative stress exceeds a servicemember-specific threshold, and then develop symptoms...

An Algorithmic Solution to Two-Stage Transfer Lines with Possible Scrapping of Units

Shanthikumar, J. G.; Tien, C. C. - In: Management Science 29 (1983) 9, pp. 1069-1086

An important aspect of the efficient design of an automatic transfer line is the ability to understand and predict the effects of the system parameters such as the size of the intermediate buffer storage space, the cycle times, failure times, repair times, and scrap rate, on the production rate...

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...
