可變生産要員管理시스템에 관한 硏究 = A Research on the Flexible work force control system

다국어 초록 (Multilingual Abstract)

This research is concerned with production smoothing and-planning deal with the setting of work force levels to satisfy demand requirements. The need for production planning results primary from aggregate demand fluctuations. such as those that occur for seasonal product families and needs diversification.
Till the present time, Many work force strategies explored in order to solve the problem of the work force flexbility under fluctuation of demand. These strategies are categorized three strategies that are predominant in today's management.
One type is chase strategy, often used by firms that employ low skilled workers and faced with seasonal product demands, where workforce levels fructuate according to increases and decreases in production requirements. A level-flexible strategy, commonly called the Toyota system, keeps the aggregte workforece at a constant size but by having flexibly trained workers at a constant it can allow transfers of workers between various departments and processes as production requirements dictate. The third major type is a level-inflexible employed by American automobile manufactures. Under this strategy, the number of workers remains constant in each department as well as at the aggregate level regardless of short term changes in the production requirements.
As the manufacturing system is envisioned by Various internal-external Environment fctors.
The staffing decision is more complex than just determining the number and timing of the work force the development of good staffing plans must consider the impact of Environmental factors like work space, work load variations, employ capabilities, machine per man power requirements, and available part time labor market restriction.
With these environmental factors explicitly estimated, managers can weigh them against desired part time work force level goals to determine the apropriate balance.
These pure strategies can not solve the whole problems of Flexibility. because the chase strategy constrained by external Environment factors (imployee morale, a labor union, etc). level flexible strtegy and level inflexible strategy has no external flexibility to meet chnges in production requirements. in this viewpoint I suggest that the operation Analysis matrix model for a production smoothing with PTS and Transportation model's concepts.
This matrix model will solve those whole problems with mixed strategies by PTS plus Automation.
