Planning Horizon Procedures for Machine Replacement Models
Sethi, Suresh; Chand, Suresh - In: Management Science 25 (1979) 2, pp. 140-151
This paper develops efficient forward algorithms and planning horizon results for several machine replacement models … mat the optimal replacement decision for the first machine (new or existing) based on the forecast of machine technology … technology only up to some finite period T, these results represent a major advance in the machine replacement literature. These …

Turnpike Horizons for Production Planning
Thompson, Gerald L.; Sethi, Suresh P. - In: Management Science 26 (1980) 3, pp. 229-241
A quadratic model for production-inventory planning was made famous by Holt, Modigliani, Muth, and Simon in 1960 in (Holt, C. C., F. Modigliani, J. F. Muth, H. A. Simon. 1960. Planning Production, Inventories, and Work Force. Prentice-Hall, Englewood Cliffs, New Jersey.), especially for its...

The Two-Product, Single-Machine, Static Demand, Infinite Horizon Lot Scheduling Problem
Boctor, Fayez Fouad - In: Management Science 28 (1982) 7, pp. 798-807
In this paper, we deal with the two-product, single-machine, static demand, infinite horizon lot scheduling problem. After a quick review of the literature, the necessary and sufficient conditions for feasibility are derived without imposing any preliminary requirements. Then, an optimal...

A Comparison of Strategies to Dampen Nervousness in MRP Systems
Blackburn, Joseph D.; Kropp, Dean H.; Millen, Robert A. - In: Management Science 32 (1986) 4, pp. 413-429
This research examines the effectiveness of alternative strategies for dealing with the problem of order instability, or nervousness, which occurs in Material Requirements Planning systems. Nervousness can be particularly disruptive in multi-level production processes where a change in order...

Freezing the Master Production Schedule Under Rolling Planning Horizons
Sridharan, V.; Berry, William L.; Udayabhanu, V. - In: Management Science 33 (1987) 9, pp. 1137-1149
The stability of the Master Production Schedule (MPS) is a critical issue in managing production operations with a Material Requirements Planning System. One method of achieving stability is to freeze some portion or all of the MPS. While freezing the MPS can limit the number of schedule...

An Analytic Framework for Evaluating Rolling Schedules
Baker, Kenneth R.; Peterson, David W. - In: Management Science 25 (1979) 4, pp. 341-351
A rolling schedule is formed by solving a multi-period problem and implementing only the first period's decisions; one period later the multi-period model is updated and the process repeated. In this paper, we provide a general framework for analyzing rolling schedules, and we examine...

Deterministic Capacity Expansion Under Deterioration
Rajagopalan, S. - In: Management Science 38 (1992) 4, pp. 525-539
This paper considers the deterministic capacity expansion problem with deterioration. First, the paper extends the conventional model by incorporating capacity deterioration effects and operating costs that are a function of: (i) the age of the facility and (ii) the extent of utilization of...

Rolling Horizon Procedures for the Facilities in Series Inventory Model with Nested Schedules
Chand, Suresh - In: Management Science 29 (1983) 2, pp. 237-249
This paper develops rolling horizon procedures for solving a multistage inventory problem with facilities-in-series. In such an inventory system, we assume that the raw material is processed successively through several facilities before reaching the customer. The input to a facility comes from...

The Optimality of (s, S) Policies for a Stochastic Inventory Problem with Proportional and Lump-Sum Penalty Cost
Aneja, Yash; Noori, A. Hamid - In: Management Science 33 (1987) 6, pp. 750-755
In this paper we consider a single product multi-period inventory problem for which the penalty cost consists of two parts, a lump-sum portion which is independent of the size of the shortage and a portion which is linear in the size of the shortage. We show that for all nonincreasing demand...
