The purpose of this paper is to develop an efficient production strategy with changing factors to influence the productivity. The factors would be the number of Multi-Function worker, the method of job dispatching, and lot size. A simulation model has been developed for this study. We used AutoMod simulation and the process activity was animated to follow the flow of process easily. The alternatives have been tested through the simulation model, and the various alternatives is proposed for the efficient production strategy. We hope that the system is applied to similar types of small and medium-sized enterprises to develop an efficient production strategy and to achieve the satisfactory result.

We suggested the policy of labor management in pump manufacturing industry through survey in order to improve competitive ability. In pump manufacturing industry, since it is difficult to find sufficient worker having technical skill and knowledge concerning pump manufacturing technology, therefore the industry must cultivate the employee systematically. We reached the result, production engineer and R&D engineer play an important role to improve competitive ability in pump manufacturing industry. Though they need technical education, the effect of education was not satisfactory. To solve this problem, suitable technical education course must be devised. Marketing reinforcement is a important factor in pump manufacturing industry. To achieve marketing reinforcement, each company must develop their present technology further and raise marketing ability to expand internal and external business. It is also consulted to use IT technology.

본 연구에서는 hollow fiber 막모듈을 통한 순수 CH4, CO2 기체와 CH4/CO2혼합기체의 투과 특성을 살펴 보고, 이를 모사값과 비교하여 보았다. 순수 기체의 투고율은 온도에 따라 Arrhenius type으로 증가하였으며, 활성화에너지는 CO2는 6.61kJ/mol, CH4는 25.26kJ/mol로 나타났다. 혼합기체의 투과에 있어서 투과부의 유량과 CO2 조성, 그리고 배제부의 CH4조성은 cut의 증가에 따라 증가하였다. 분리인자는 5~20atm의 압력과 cut이 20으로 고정된 상태에서 20~40의 범위에 있었으며, 압력이 증가하고 온도가 감소할수록 증가하는 경향을 나타내었다. 실험결과와 모사결과는 투과부 유량과 CO2조성의 경우 8% 이내에서, 배제부의 CH4조성의 경우 15% 이내에서 일치하였다.
