The pattern of changes in the Extended Learning Curves representing the performance of 114 assembly workers in an electronics firm is examined in terms of changes in productivity drift over long periods of time. It is shown that 2 types of discontinuities can occur. The first consists of a temporary levelling off in productivity followed by a recovery to new higher levels of productivity; the second has a sustained period of negative productivity drift. A number of work facets are statistically tested as possible causes of these patterns of productivity drift, but, the only significant relationship (at P ≤ 0.05 level) is with length of service in job. Some evidence is presented to show that conventional work measurement methods are not effective in terms of assessing the true work output of experienced workers since such workers are able to beat the system by claiming those allowances which are most difficult to cross-check. 相似文献

The successful introduction of robots into an industrial enterprise means real commitment, engineering support, and detailed involvement in the planning of an integrated manufacturing system. In particular, the production engineer is clearly seen in this context to be the system designer. He must therefore be in a position to specify the performance of all man and machine components within the system such that productivity is maximised. Robot types are reviewed, and analogies between man and machine are used to introduce the RTM concept. Finally, a simple method is given for estimating robot throughput times from elementary velocity profiles. The fall-off in throughput due to the effect of many small robot movements is emphasised. 相似文献

A detailed chronology of a unique response to organizational change is explored and discussed through the example of the Chaplaincy Staff Support Service at Hamilton Health Sciences. Highlighted are the corporate and staff benefits of using chaplains' skills, training and existing roles in hospital life. A summary of the specific methodologies are provided to clarify the theoretical discussion. It is concluded that this is a fiscally efficient means of supporting staff to live out the highest organizational principles in difficult times. 相似文献

ResumenEn este artículo se analizan los datos de cuatro ciudades fronterizas de México. Estas son evaluaciones sobre el carácter e identidad nacional, inferidas a partir del sentido de pertenencia y participación de los ciudadanos en las instituciones más importantes de su Estado. Los resultados muestran que los habitantes de las ciudades fronterizas tienen un sentimiento de pertenencia muy reducido y un aún menor sentimiento de participación en las instituciones. 相似文献
