This paper explores methods for scheduling preventive maintenance by means of mathematical programming. Five integer linear programming models are posed, each based on a different optimality criterion dealing with manpower smoothing. By means of two hypothetical examples the models are tested...

Capacity of a facility is defined as its maximum rate of production. Although capacity can be changed by paying the appropriate capital costs, it is often impossible or undesirable to expand or contract capacity to meet exactly a time-varying demand. This paper presents work designed to help...

This note extends some work by Manne [Manne, A. S. 1961. Capacity expansion and probabilistic growth. Econometrica 29 (4, October).], which dealt with the case where demand was growing linearly, and also some work by Srinivasan [Srinivasan, T. N. Geometric rate of growth of demand. Investments...

This paper considers the properties of an optimal production schedule for a multi-product firm, where the economics of production include employment smoothing costs. The results extend the findings of [Lippman, Steven A., Alan J. Rolfe, Harvey M. Wagner, John S. C. Yuan. 1967. Optimal production...

We study how industry clockspeed, internal firm factors, such as product development, production, and inventory costs, and competitive factors determine a firm's optimal new-product introduction timing and product-quality decisions. We explicitly model market demand uncertainty, a firm's...

Who says a committee can't write a cogent report? Having reread the Guidelines and Appendix I (pp. 1127-1148) several times since publication, I am favorably impressed with the document's perspicacity. I make this statement not only to extend my compliments to the ORSA Ad Hoc Committee for a...

In this paper we study a model that minimizes the sum of production, employment smoothing, and inventory costs subject to a schedule of known demand requirements over a finite time horizon. The three instrumental variables are work force producing at regular-time, work force producing on...

This paper demonstrates the equivalence of several published algorithms for solving the so-called linear fractional programming problem.
