摘要:

This paper describes the SAMMIE/AUTOMAT computer package. The overall objective of the research has been to provide a range of computer techniques which could be made available to the work study practititioner to aid him in the design and evaluation of work tasks. The work place, parts and the operation may be specified in any of a variety of ways and the computer will then produce times for the work based on the MTM-2 pre-determined motion time system. Facilities within the AUTOMAT system include the production of a work place layout, a computer derived methods analysis, assembly line balancing routines (not described in this paper), and the use of conversational graphics methods. The paper illustrates the use of the system by the analysis of a simple job and also discusses the advantages and disadvantages of conversational mode working.

摘要:

The paper explains how simple ideas in the field of group technology have led to the development of a new system of production, called the cell system, which differs from, but complements, flow-line production and traditional ‘ job and batch ’ (functional layout-based) production.

摘要:

An analysis hag been made of the amount of discretion available to the employees on the shop floor of a medium batch production factory. Four different levels of discretion wore identified. The amount of discretion which employees possess was shown to be closely related to the satisfaction of the employees' personal economic objectives.

摘要:

The expansion and contraction of product lines in a company is a decision which affects marketing, production, and distribution staff collectively. This paper establishes a model for a multi-factory company which markets a variety of products in different market sectors with different distribution costs. The problem is to determine how much of each product to manufacture at each factory, whether overtime should be used, how much expenditure to put into selling the product, and how it should be priced. Linear programming has already been used to tackle the product mix problem and this model extends it to include the marketing variables and the possible use of extra capacity. The objective is to make the annual product line plans to maximize total variable profit. The model is illustrated on a simple example. It is organized into a computer programme for accepting files of typical accounting data and providing a variety of management reports.

摘要:

Optimization is rightly claimed to be the most significant factor distinguishing the modern approach to machining processes from the orthodox one. Practical results can be obtained from the application of mathematical modelling and optimization techniques.

摘要:

The problem of backlash in gear mechanisms is approached from the point, of view of a decision-maker, The elements of Bayesian Decision Theory are described and their significance is related to the backlash problem. The Normal statistical model is motivated as the basis for decision analysis with and without observational data. Each step of the analysis is examined in detail for the backlash problem, and is illustrated by a simple but realistic numerical example.

摘要:

The paper gives a qualitative treatment of a new approach to the synthesis of sequential control systems. Complex sequential control systems can be assembled from a relatively small number of standard sequence packages. These have useful sequential properties in their own right, but the methods for coupling them together to form larger sequential systems are described by the authors. Additional benefit is gained by using the machine actuators alone as memory devices. This removes any possibility of unintentional disturbance of the state of the memory function in the control system. Three examples are chosen to illustrate the design process.

摘要:

Machinability equations have been developed for prediction of tool life when machining XC 45 steel with P 10 and P 30 carbide inserts. A marked difference in cutability was observed between separate batches of P 10 inserts. A new criterion of tool life is suggested.
