Showing papers in "Journal of Operations Management in 1989"

TL;DR: A review and critique of the research in operations, itemizing the shortcomings identified by researchers in the field, is presented in this article, where the authors suggest a new research agenda with an integrative view of operations' role in organizations, a wider application of alternative research methodologies, greater emphasis on benefit to the operations manager, cross-disciplinary research with other functional areas, a heavier emphasis on sociotechnical analysis over the entire production system, and empirical field studies.

TL;DR: Yield management as discussed by the authors is a technique that allows the airlines to allocate their fixed capacity of seats in the most profitable manner possible, and has been widely used in the airline industry.

TL;DR: In this paper, the authors examine an underlying argument that proper strategic positioning or aligning of operations capabilities can significantly impact competitive strength and business performance of an organization and conclude that further understanding of these premises could be benefited by more careful and consistent definition of operations strategy concepts and terminology.

TL;DR: Four different forecasting procedures, based upon different amounts of information, are developed and most of the benefit associated with using the costly approach of identifying and tracking the issues and returns of individual containers is achieved by the more practical method of recording only aggregate issues and aggregate returns period by period.

TL;DR: In this article, a group of 65 manufacturing managers (vice-presidents, plant managers and manufacturing directors) were brought together and divided into seven small groups, each of which had direct responsibility for from one to five manufacturing plants of various sizes.

TL;DR: The state of OM research in the United States is examined through a survey of published journal articles by operations management researchers in the period 1982-1987 as discussed by the authors, where 362 journal articles were reviewed and classified into 17 categories: technology and innovation, service operations, productivity, and manufacturing strategy.

TL;DR: Results presented using statistical and graphical analysis show that there is no statistically significant difference in the performance using finite loading and infinite loading release mechanisms, and succeeding increases in labor flexibility show a diminishing return in shop performance.

TL;DR: In this paper, the authors examined the impact of using safety stock at the master production schedule (MPS) level to act as a buffer against differences in actual and forecast requirements and concluded that safety stock should be used with caution if it is introduced for the purpose of stabilizing schedules.

TL;DR: It is concluded that, despite the enormous interest in lot-sizing research over the years, the “scientific” body of knowledge, as it can be applied in practice, remains relatively undeveloped.

TL;DR: It is shown that the performance of different dispatching rules does indeed depend upon the degree of workload imbalance, and that a job shop or automated manufacturing system would likely benefit from implementing optimal-seeking scheduling rules instead of the traditional job dispatch rules.

TL;DR: It is claimed that due to the nature of practical disaggregate problems, oft cited linear programming models will be set aside by more flexible goal programming solutions that explicitly recognize the dynamics of variations in product mix, production rates and management objectives.

TL;DR: It is shown that the level of tooling availability has a significant impact on shop floor performance as measured in terms of mean flow time, mean tardiness, number jobs tardy and number of tool changes.

TL;DR: In this article, the authors examined the performance of fourteen due-date oriented sequencing rules in a simulated ten-machine multistage job shop having one assembly work center, and evaluated the sensitivity of the sequencing rules and progress milestones to the complexity of product structure.

TL;DR: This paper pointed out that Hillier and Boling's original results 1967 were due to an assumption of unrealistically large variations in processing times, and pointed out the need to orient future efforts toward practical integration of the bowl phenomenon result with other findings that relate to improving the throughput of unpaced assembly lines.

TL;DR: This pape shows how information regarding congestion levels on the shop floor can be used to assign due dates to arriving jobs in such a way that the mean tardiness of jobs is decreased without increasing the average length of the promised delivery lead times.

TL;DR: In this paper, the bowl distribution is used to unbalance an unpaced assembly line with high service times at the beginning and end of the line and low service times placed in the middle of line.

TL;DR: In this article, the authors present a very fast microcomputer implementation of the Wagner-Whitin algorithm for the case of concave procurement cost structures, and show that the algorithm will solve problems in linear time.

TL;DR: A qualitative comparison between the MILP approach and the heuristic algorithm in this study suggests that the introduction of demand uncertainty has the effect of reducing the experimental differences between the two techniques.

TL;DR: In this article, the authors examined the cash flow consequences of nine production planning strategies consisting of three master production scheduling methods and three component/part scheduling methods, and found that a smoother master production schedule tends to result in more stable cash outflow patterns.
