TL;DR: In this paper, the problem of determining lot-sizes for a group of products which are produced at a single workcentre is considered, where the requirements for each product are known, period by period, out to the end of some common time horizon.

TL;DR: In this paper, the average lightness of the due-dates is assumed to be governed by a policy constraint, which is linked analytically to the parameters of the decision rules for due-date assignment.

TL;DR: The Precedence Diagramming Method (PDM) as mentioned in this paper is an activity-on-node network and additional precedence relationships, which offers an easier and more flexible network approach to modeling large projects than conventional PERT/CPM.

TL;DR: In this article, the benefits and costs of MRP systems are described based on a large survey of users, who report that they have achieved significant improvements in inventory turnover, delivery performance, and other benefits, and that further improvements are expected when their systems are fully implemented.

TL;DR: This paper surveys the implementation literature primarily in three fields: management information systems, operations research/management science, and production-inventory management, and divides this documented material into three diverse categories of pitfalls in implementation.

TL;DR: A model for further research with respect to job shop scheduling is suggested and it is suggested that schedulers may be influenced by other factors.

TL;DR: In this article, a simple polynomial equation whose coefficients can be determined by means of regression analysis techniques is a good, basic tool for estimating overall inventory levels and can be used to provide insight into the effectiveness of inventory control policies at different stocking points.

TL;DR: In this paper, the authors present an approach for studying and monitoring transient behavior of unpaced production lines, and report some important transient operating characteristics previously overlooked, and demonstrate that the conflicting results reported in some of the earlier simulation studies are due to an inadequate accounting for transient behavior.

TL;DR: Specialized algorithms are developed which are less complex and consequently more efficient than existing algorithms and compared with alternative algorithms on the basis of slack dispersion which suggested the existence of a trade-off between the execution efficiency of the algorithms and their slack disp immersion characteristics.

TL;DR: This paper presents an understandable and straight-forward method for making work force level and inventory planning decisions, i.e., dynamic aggregate planning decisions based on a ratio, named RPCC, which represents the relative value of the cost of changing the production level to thecost of carrying inventory.

TL;DR: Results indicate that dynamic programming can be an attractive methodology to attack this complex problem of commercial bank check processing encoder scheduling.

TL;DR: In this article, an attitudinal and behavioral change program was developed and implemented in a service operations function, which stabilizes operations management (reducing turnover) and improving attitudes and behaviors of employees with strong union affiliations in a common carrier trucking terminal when compared to similar employees in a control terminal undergoing no planned change.

TL;DR: In this article, simple heuristic methods are presented for three different types of uncapacitated problems: (1) unlimited facility capacity with no fixed cost; (2) unlimited capacity capacity with a fixed cost for assignment; (3) multiperiod problems.

TL;DR: A new technique, termed the declining alpha method, is presented and shown to preserve the exponential weight pattern, which is important in that it minimizes a measure of forecast error.

TL;DR: A solution procedure is given to minimize the expected total of the costs associated with the quality of the finished product subject to a limit on the Average Outgoing Quality Limit of thefinished product.

TL;DR: In this paper, an actual multi-item periodic-review inventory control study conducted in a developing country is presented, where two formulations of an actual inventory control problem, one much easier and less costly to implement than the other, are shown to be equivalent with respect to the optimal solution.

TL;DR: In this paper, a new theory of spatial arrangements is proposed and tested in an exploratory fashion, and suggestions are made on future research and how prescriptive models can be reformulated to better handle the behavioral aspects of office layout.

TL;DR: In this paper, a case study of computerized forecasting of the average daily solid waste quantity generated, month by month, in Sacramento County, California, is presented, where the monthly pattern of peaks and valleys and the month-by-month trend in solid waste generation are identified.
