摘要:
We study the scheduling of n independent jobs on m parallel identical processors. Using dynamic programming, the paper presents an algorithm to determine the optimal schedule for medium size problems with quite general cost functions. The application of the algorithm is illustrated by numerical examples.

摘要:
This paper describes an industrial scheduling problem taken from a cable manufacturing process. An heuristic solution procedure known as the CMD rule is presented for this multi-product, multistage, continuous flow problem. The solution procedure is designed to minimize the sum of idle time of machines and in-process waiting at the second stage. A comparison of this rule with some standard scheduling rules is provided.

摘要:
The relative wear of a single point diamond, defined in terms of the grinding force, was determined for a group of A12O3and Si3N4. It was found that the wear rate is directly related to the mechanical properties of the workpiece and the grinding environment.

摘要:
This paper presents two new solution procedures for a deterministic lot size problem, a matrix algorithm and a heuristic matrix method. The algorithm is based on the dual of a linear programming model formulation of the lot size problem, and it provides optimal solutions even in the general case of time-varying parameters. A comparison of the efficiency of the new solution procedures with well-known methods is developed. New applications of the techniques described within the fields of engineering (optimal design of a pump-pipe system) and economics (a model for import-planning) are referred to.

摘要:
This paper deals with a method for scheduling and control of a maching job shop where the average number of operation stages per part is six and the average operation time per stage is about one hour. The method is based on the adjustment of load balance among machines and the limitation of the amount of work input. By simulation with real data, it was found that two variables, the load balance and input amount of work, definitely influence shop performances such as lateness, mean flow time and utilization of machines. If these two variables are well controlled, good results can be obtained no matter what the dispatching priority rules on the shop floor may be.

摘要:
Inventory models which permit coordinated control (or joint replenishment) of families of items are of considerable interest in practice. A major complexity in coordinated control is that, typically, one item triggers the family order and the other items have stock remaining above their reorder points. Account should be taken of this so-called residual stock when establishing the reorder points. In this paper, modelling the inventory position as a diffusion process permits us to develop expressions for the components of the residual stock probability density functions. Heuristics are presented for quick calculation of these expressions. Then we show how residual stock is taken into account in determining the reorder points of the individual items. The relationship of these residual stock pdf expressions to other components in a new class of coordinated control models is also discussed. This class of models has been shown to outperform existing models (IBM's IMPACT Inventory Control package(.

摘要:
Inventory control models which provide coordinated control ( or joint replenish ment) of families of items are very useful in practice. These models require expressions for the residual stock levels for each item in the family when a replenishment is placed. In this paper expressions are developed for the periodic review residual stock probability density function, when inventory position is modelled as a diffusion process, and heuristics are presented for quick calculation of these expressions. The importance of residual stock in setting inventory control model parameters is illustrated by showing how residual stock is taken into account in establishing item reorder points. The relationship of these residual stock pdf expressions to other components in a new class of coordinated control models is also discussed. This class of models has been shown to outperform existing models (IBM's IMPACT Inventory Control package).

摘要:
The work described in this paper is part of a large investigation of the usage of statistical methods of quality control (SQC) in British manufacturing industry. The introduction provides a review of previous work, which revealed that industry in the UK makes surprisingly little use of SQC techniques. These results were so striking that a further investigation was initiated to discover:

摘要:
Cyclic queue models have been used in the past to determine fleet size and evaluate fleet performance. Analytic solutions can only be obtained for exponential service times or exponential service times plus a generalized transition time. We have carried out several hundred simulations of cyclic queues with non-exponential service times and have developed a technique for estimating the effect of non-exponential distributions using the analytic results as a basis. Most of the work presented here deals with single-lobe systems. We also present some results for multi-lobed cyclic queues which introduce new problems of analysis and evaluation.
