摘要:

A Markov process discrete in both time and space is used to establish a mathematical model for the analysis of delays associated with materials handling at conveyor-serviced production work stations. The model design assumes the physical ability to load processed units into conveyor spaces from which unprocessed units have just been removed.

摘要:

Studies are made of various groups of workers engaged in repetitive tasks; photographic and activity sampling techniques are used to record postural behaviour. Measurements are made of dimensions of operators and their machines and workplaces relevant to the working relationship between them. As a result of the studies modifications are made to machines and workplace layouts, and changes in postural behaviour and workers' reports of feelings of fatigue are noted.

摘要:

The drawings required for the manufacture of any commodity are functional in nature, illustrating the purpose of each component and its relationship to other components. Organisations are represented by hierarchical diagrams, but their functions cannot be understood or constructed from such diagrams. A technique for the design of organisations and their illustration on a functional basis is given. The application of the technique in the range from the single entrepreneur to the large enterprise is illustrated.

摘要:

The paper shows how the governing equations are modified by allowing a variation in yield stress throughout a deformation zone. The limitations imposed by these equations are discussed and a method is proposed to illustrate the effect of variable yield stress on the deformation pattern. From the study of a particular solution of plane strain extrusion, it is concluded that variation in yield stress should not markedly change the pattern of deformation from that appropriate to a non-hardening situation. This conclusion, therefore, gives support for the mean strain solution currently employed to accommodate strain hardening, particularly if this method is applied incrementally along the streamlines.
