TL;DR: This work investigates priority rules aimed at minimizing tardiness, emphasizing a “modified duedate rule” which functions effectively in conjunction with internally-set deadlines and which adapts to both tight and loose conditions in the due-dates.

TL;DR: The results indicate that operation due dates improve every conventional measure of job shop performance.

TL;DR: In this article, a Japanese just-in-time (JIT) production system is compared with MRP, and the Japanese JIT system is explained with reference to a graphical cause-effect model.

TL;DR: The results indicate that, under certain conditions, the computationally simple Silver-Meal heuristic provides lower lot-sizing costs than the Wagner-Whitin algorithm.

TL;DR: This article identified and examined four distinct multi-plant strategies prevailing within the nation's largest manufacturing companies and reported on the apparent attractiveness of different strategies to different industry groups and singled out those specific plant characteristics which Fortune 500 plants attribute most often to each strategy.

TL;DR: In this paper, a large-scale survey of companies involved in MRP implementation was conducted to develop a profile of problems typically encountered during the implementation process, and a discriminant analysis was used to determine which of those problems, and additional factors, appear to affect the success or failure of MRP implementations.

TL;DR: It is shown how different decision levels supported by decision models were integrated in these two applications and how the crucial role of crossfunctional managerial committees in the integration process and the introduction of slack to avoid disaggregation problems were presented.

TL;DR: The results of the experiment confirm MOM (and to a lesser extent LUC) as an effective lot-sizing procedure and shows that the differences between the procedures tend to vanish as the amount of uncertainty in the requirements increases.

TL;DR: In this article, the challenges and imperatives for research in service operations management (SOM) are discussed, and a broad perspective that includes the customer and the interactions with other functional areas is presented.

TL;DR: In this article, the adoption and implementation of new manufacturing processes are conceptualized in terms of coping with uncertainty, and various coping strategies must be employed to deal with the situation of uncertainty.

TL;DR: In this paper, a heuristic algorithm is developed and applied to determine lot sizes and production sequence on a single facility, where various product demands are treated as deterministic and time varying (dynamic) over a finite planning horizon, such as that generated from a material requirements planning (MRP) system.

TL;DR: The purpose of this paper is to describe the operational features of the four capacity planning techniques, the underlying data base requirements, and some key managerial issues in choosing among these techniques.

TL;DR: These ten issues expand the solution space for lot sizing in an MRP-based system compared to a reorder point based system.

TL;DR: It is suggested that inexperienced, untrained human schedulers can consistently find traveling salesman solutions as good as or better than all but one of the seven heuristic algorithms tested (including the widely used ClarkeWright distance saved heuristic and the recently published largest-angle insertion heuristic).

TL;DR: A study to select permanent emergency ambulance sites for the city of Austin, Texas found 12 locations for EMS vehicles to be phased in over a five year period using a facility location algorithm developed to capitalize on a large data base of interzone travel times.

TL;DR: This paper illustrates how a modern requirements planning system for surgical supplies was developed for a private hospital in Houston and used to effectively hold inventory levels to the minimum required to support a detailed schedule of surgical procedures.

TL;DR: A queuing based simulation model is used to derive expected service levels for a number of different performance measures and tradeoff curves are mapped between specified performance measure levels and utilization rates of patrol vehicles.

TL;DR: This study investigates the behavior of a job shop depicted as an integral component of a firm and suggests that conventional open-loop job shop studies tend to neglect important interactions with factors external to the shop itself.

TL;DR: The paper addresses the problems of finding a location on the network for the (m +1 )st facility corresponding to a given total expected demand and of determining which demand points will be served by which facility.

TL;DR: A decision making aid in the form of a production planning model which is immediately responsive to changes in the economic environment is described, which provides cost minimization solutions to “what if” questions of management through the use of linear programming.

TL;DR: In this article, a successful application of classical inventory theory at a drug manufacturing plant located in Montreal that has resulted in annual savings in the order of $110,800 and assisted management in its decision to invest in larger production equipment.

TL;DR: Simulations comparing work center control rules to the critical ratio rule for job dispatching indicate that work centers control can increase performance to customer due date while simultaneously reducing average work in process inventory.

TL;DR: Work-in-process effects on learning curves have been examined in this article, where the authors examined the effects of work-inprocess inventories on learning curve construction and found that the effect of work in process on curve construction is less critical than the basic inclusion of this parameter in curve construction.

TL;DR: In this article, the authors compared the use of four static and two dynamic priority rules for sequencing bundled checks in the check clearing operations in a bank's back office, and found that the two dynamic rules performed statistically better than three of the four static rules tested.
