| Summary: | 碩士 === 國立中央大學 === 工業管理研究所 === 95 === The objective of this paper is to examine the impact of introducing a multistage distribution in the computer service facility. Cheng(1997) had derived the model which considered the circumstances of computer systems subject to breakdowns and was described with exponential distribution. However, in practice, services provided by a computing center to a user might not be consisted of a single step but often several steps. Consequently we consider a more general distribution to relate the operation of computer systems. Under the same condition of systems breakdown discussed in Cheng(1997), we discuss the pricing and capacity decision of the service facility, renew the model of users’ expected waiting time in the system, and analysis the results between different parameters setting. We compare our model with Cheng(1997) numerically and graphically, and discuss the implication of these different results.
