Most of the recent studies of heuristic lot-sizing techniques for multi-stage material requirements planning systems have investigated the problem in the context of a single stage. In this paper, the multi-stage problem is first modeled analytically to indicate the potential errors inherent in...

We propose a behavioral theory to predict actual ordering behavior in multi-location inventory systems. The theory rests on a well-known stylized fact of human behavior: People's preferences are reference-dependent. We incorporate reference-dependence into the newsvendor framework by assuming...

A quadratic model for production-inventory planning was made famous by Holt, Modigliani, Muth, and Simon in 1960 in [3], especially for its application to a paint factory. A discrete control version of a related quadratic production-inventory model was studied by Kleindorfer, Kriebel, Thompson,...

This paper develops efficient forward algorithms and planning horizon results for several machine replacement models under an improving technological environment over time. The models are that of cost minimization, profit maximization, and cost minimization with probabilistic breakdowns. The...

In this paper, I provide some observations on how the academic field of Operations Management has changed over the past 40 years. For this purpose, I have identified and classified the Operations Management papers published in Management Science in 1976 and in 2016. Based on this review I...

The focal point analysis is a viable approach to analyze models of finitely durable goods in infinite time horizon. Agrawal, Ferguson, Toktay, and Thomas [Agrawal VV, Ferguson M, Toktay LB, Thomas VM (2012) Is leasing greener than selling? Management Sci. 58(3):523-533.] study the focal point of...

This study examines the ability of economists to forecast ten major economic series. The data for this study were provided by J. A. Livingston of the Philadelphia Inquirer, who since 1947 has collected forecasts for the upcoming 6 and 12 months. The results reveal that, in general, for the...

In this Note we present an alternative formulation to the MRP lot sizing model of Steinberg and Napier (SN) (Steinberg, E., H. A. Napier. 1980. Optimal multi-level lot sizing for requirements planning systems. Management Sci. 26 (2) 1258--1271.). The alternative is more parsimonious and the...

This paper is concerned with the problem of maintaining open order due dates in job shops that plan and schedule their operations using Material Requirements Planning (MRP) methodology. Two different techniques for dealing with open order due date changes are analyzed using customer service...

In this Note, we address the issue of safety stock considerations in an MRP environment through the use of a single identical component as a replacement for a set of multiple components. We indicate where the results reported by Collier (Collier, David A. 1982. Aggregate safety stock levels and...
