摘要：In this paper, we develop an approximate model of an inventory control system in which there exist two options for resupply, with one having a shorter lead-time. We assume that demand and the fixed ordering costs are small relative to the holding cost so that a one-for-one ordering policy is appropriate. We consider a policy for placing emergency orders that uses information about the age of outstanding orders. We derive the steady-state behavior of this policy and present some computational r...

摘要：Motivated by scheduling problems that arise in flexible manufacturing systems, we develop a heuristic procedure to obtain effective flow control (sequencing, routing, and input control) policies for multiclass queueing networks. The procedure employs a Brownian model of J. M. Harrison that approximates a multiclass queueing network with dynamic scheduling capability, if the total load imposed on each station in the queueing network is approximately equal to that station's capacity. In this pap...

摘要：The problem of data verification may be described as two sides that have concluded a contract stipulating that one side (the inspectee) is to report a set of data to the other (the inspector). The inspector has to decide on the basis of his own measurements whether to accept the data reported by the inspectee as correct or to assume they have been falsified. This situation is modeled as a statistical game, and practical solutions are supplied. We consider the verification of n data with a samp...

摘要：The theme of the October 29-31, 1990, ORSA/TIMS meeting in Philadelphia was Productivity and Global Competition. This paper, which is an address given there, pursues this theme by emphasizing the importance of knowledge in contrast to natural resources as the critical ingredient in economic development in the future, and stresses the rapidity with which knowledge is transferred across national boundaries and the impossibility of restraining it. It forecasts that the competition among nations w...

摘要：FORPLAN (FORest PLANning) is a large-scale linear programming system used to support national forest land management planning. It is available in two versions, and is used extensively to help interdisciplinary planning teams develop forest-wide plans as dictated by the National Forest Management Act of 1976. Nine years of experience clearly show that while the system is working in a technical sense, troublesome issues remain. This paper begins with an overview of how USDA Forest Service planni...

摘要：Bidding at U.S. offshore oil and gas lease sales is characterized by high stakes, enormous uncertainties, and many interrelated decisions. The Lease Bidding Strategy System combined techniques from decision analysis, statistics, and nonlinear optimization to provide information and insights to management responsible for bidding at Gulf Oil Corporation. It was used prior to every major federal lease sale from September 1980 until Gulf was acquired in 1984, during which time Gulf's bids exceeded...

摘要：This paper describes a line segmentation problem in a multistage, multimachine production system. The production facility can concurrently produce several types of circuit boards because each production stage consists of multiple machines. The items produced are categorized into families, and items belonging to the same family share the common major setup, while switching over from one family to another requires a major setup. The line segmentation problem determines an allocation of machines ...

摘要：This paper treats a version of the Economic Lot Scheduling Problem (ELSP) in which items may be produced several times in different amounts during a cycle. We show how to compute the optimal lot sizes and cycle length, given the sequence of items in a cycle. This requires solving a parametric quadratic program, plus a few EOQ calculations. Our procedure is designed to be used along with a heuristic for selecting the sequence of items in a cycle, such as the one proposed in 1987 by G. Dobson. T...

摘要：In this paper, we address the problem of scheduling a number of jobs on a bank of parallel machines to minimize the total weighted tardiness, under the assumption that the weight of each job is proportional to its processing time. The version of the problem that has general weights has been shown to be strongly NP-complete. We prove this version of the problem to be NP-complete, and give a pseudopolynomial time algorithm for solving it. We study a family of simple sequencing rules in which the...
