A Branch-First, Cut-Second Approach for Locomotive Assignment

Ziarati, Koorush; Soumis, François; Desrosiers, Jacques; … - In: Management Science 45 (1999) 8, pp. 1156-1168

The problem of assigning locomotives to trains consists of selecting the types and number of engines that minimize the fixed and operational locomotive costs resulting from providing sufficient power to pull trains on fixed schedules. The force required to pull a train is often expressed in...

Decomposed Versus Holistic Estimates of Effort Required for Software Writing Tasks

Connolly, Terry; Dean, Doug - In: Management Science 43 (1997) 7, pp. 1029-1045

We examine decision analysis' central "decomposition principle" in the context of work-time estimates of software … actual outcomes falling in the 1% tails of estimated distributions. This overtightness was unaffected by task decomposition … best level of decomposition at which to elicit work-time estimates may depend on task, judge, and elicitation method. …

The Reliability of Subjective Probabilities Obtained Through Decomposition

Ravinder, H. V.; Kleinmuntz, Don N.; Dyer, James S. - In: Management Science 34 (1988) 2, pp. 186-199

The use of decomposition as a procedure for improving the consistency of subjective probability encoding is discussed … decomposition estimates as a function of characteristics of the component assessments. Decomposition is compared to direct … assessment in terms of the percent change in measurement error that can be attributed to the use of decomposition. Potential …

When Does Forced Idle Time Improve Performance in Polling Models?

Cooper, Robert B.; Niu, Shun-Chen; Srinivasan, Mandyam M. - In: Management Science 44 (1998) 8, pp. 1079-1086

Sarkar and Zangwill (1991) showed by numerical examples that reduction in setup times can, surprisingly, actually increase work in process in some cyclic production systems (that is, reduction in switchover times can increase waiting times in some polling models). We present, for polling models...

Queues with Slowly Varying Arrival and Service Processes

Gelenbe, Erol; Rosenberg, Catherine - In: Management Science 36 (1990) 8, pp. 928-937

We examine a generalisation of the M/G/1 queue. The arrival and service processes are governed by a Markov chain which determines the rate of arrival and the service time distribution from a finite set. This Markov chain is assumed to vary "slowly", so that we are able to derive analytical...
