| Summary: | 碩士 === 南華大學 === 管理科學研究所 === 93 === For lots of enterprises, the ministrant consumption and production exist simutaneously, so the fluctuation of service demand is hard to control. A customer usually randomly arrives, stands together and puts forward a ministrant need namely. If the service ability is already full, the customer then starts to wait. Because the arriving rate and service time is fluctuant, the waiting line happens. To speed up the ministrant speed which is an important topic, if you want to preserve the competition ability in the service market.
A customer wants a direct service especially in whenever a lot of customers in wait, therefore the service pressure is then emerging. Thus, this article would like to develope the whole new characteristic equations under the considerations of service pressure for M/M/s/k model through the Birth-and-death process, and further inquired the fluctuation of the work efficiency from the various pressure coefficients. In addition, common discussions are infinite waiting capacity and no pressure, obviously those situations are nonpratical. Therefore, this research tries to discuss the pressure condition and finite waiting capacity to make it near pratical.
