摘要:

Work structures and technical innovations which simultaneously mobilize the capabilities and skills of the individual employees to prevent dequalification make new demands on the qualification process. Training for more complex activities can therefore no longer be carried out using unsystematic forms of instruction consisting of demonstration and imitation

摘要:

This paper deals with the problem of designing an effective production system for processing agricultural products, where raw materials, are harvested seasonally and have a limited shelf-life because of their perishability, although the market demand for the final products may be reasonably uniform throughout the year

摘要:

This paper presents the results of the second phase of a detailed study of the practice and management of quality control in the chemical manufacturing industry. The first part of the investigation comprised a questionnaire survey which revealed that this sector of industry makes surprisingly low use of statistical quality control (SQC) techniques. The second part took the form of structured interviews in 16 chemical companies within the U.K. The results indicate that use of SQC is, in fact, much less than suggested by the questionnaire survey and that the main reasons for the low use are lack of knowledge and understanding of statistical techniques and their application in the industry.

摘要:

This paper provides several solution procedures for the class of lot size and order point decisions when countermeasures are necessary to avoid stockouts or mitigate their effects. Several countermeasure cost functions are incorporated when lot size and order point decisions are considered both independent/non optimal and dependent/optimal. Manual solution procedures are provided that utilize graphs specifically developed for these problems which are further explained through examples. Computer simulation procedures are developed and documented that are used to compute optimal results. Comparisons of cost results under conditions of independent/non-optimal and dependent/optimal lot sizes and order points are presented.

摘要:

This paper deals with a dynamometer for measuring cutting forces in internal broaching. Typical records of axial and radial components of broaching forces are given. The variation of cutting force with broaching speed has been studied. An empirical equation for calculating specific cutting pressure is given.

摘要:

The formation of production part-families by the application of Group Technology opens the way for more efficient manufacture. One area for improvement is reduction in manufacturing set-up times. Particular opportunities exist for minimizing total set-up time for the part-family when the set-up times for parts in the family are dependent on which part has been made immediately previously. Where the production of an entire family is to be repeated sequentially, the problem is that of cyclic scheduling, and a solution can be sought by Travelling Salesman methods. Where only selected parts from a family are to be made, and the family not repeated, the problem is acyclic. In this paper, an efficient technique is presented for determining the optimum part sequence in such an acyclic case, and the technique is illustrated by a specific industrial scheduling example.

摘要:

This paper presents an analytical study of a two-stage production system with provision for storage of intermediate product. Strict limits are placed on the size of the intermediate product inventory, and on the rates at which product can be moved into or out of inventory. Exponential service times are assumed at stage one and Erlang distributed service times are assumed at stage two. The problem is solved by formulation as a Markov process, and the impact of the inventory constraints on the production rate of the line is investigated. The problem of balancing the system is considered at some length.

摘要:

Time structure of a job is affected by the length and frequency of its constituting tasks. It is probably one of the major variables in the subjective perception of variety of jobs. This paper defines an index called Non-Repetitive Cycle Time (NRCT) which can be used as an indicator of the temporal pattern of the job. Investigation of the value of NRCT for jobs in two organizations confirmed the hypothesis that NRCT is positively correlated with the job level in the organizational hierarchy. This index can be used by job designers in estimating the temporal impact of assigning tasks to jobs

摘要:

A conveyor cost estimation methodology is developed which takes into account the two major costs of operating unit load conveyors: maintenance and power. A programmable calculator program (CONVEY) Is developed to assist the plant engineer in determining new operating conditions for the belt, such as motor size, belt tension, gear and sprocket ratio. CONVEY also computes power consumption for specified belt operating parameters.

摘要:

This paper describes a generalized heuristic to balance an assembly line where the task times may be smaller or greater than the specified cycle time. The tasks are primarily assigned to different stages by choosing different stage cycle times so as to have the stage idleness within the specified limit. Later, the line is further balanced and the stage idleness is smoothed by trading and transferring the tasks, or crashing the worst stages. The line is then balanced by adjusting the manpower at different stages. Several proofs and models have been formulated regarding the generalization of paralleling to serial line balance, some design aspects of manpower utilization, the superiority rule of strategic policy for choosing stage cycle times, etc. The balance is chosen through cost optimization.
