本篇論文分別討論有限及無限容量的 M/Eκ/1排隊系統含有一可移動服務
數累積至N 位時,服務站則立即被開啟,以服務顧客;而當系統中所有顧
服務,只有當系統中的顧客個數再累積至N 位時,才又開始被服務站服務
其結果含概了下列三種排隊系統:(1) 標準 M/M/1排隊系統;(2) 標準
M/Eκ/1排隊系統;(3) 含有一可移動服務站之 M/M/1 排隊系統。最後我
們定義出每單位時間的總穩態期望成本,然後決定出控制參數N 的最佳解

This thesis studies the optimal control N-policy of a removable
service station in an M/Eκ/1 queueing systems with infinite
and finite capacities, respectively, under steady-state
conditions. The N-policy is to turn the service station on when
the queue size reaches N which is a positive integer, and turn
it off when the system is empty. We develop the steady-state
characteristics of the infinite capacity and finite capacity
systems such as the probability distributions of the number of
customers in the system, the expected number of customers in
the system, and so on. The controllable M/Eκ/1 queueing system
generalizes the ordinary M/M/1 queueing system, the ordinary M/E
κ/1 queueing system, and the controllable M/M/1 queueing
system. We derive the total expected cost functions per unit
time, and determine the optimal value of the control parameter
N, say N*, in order to minimize the cost functions for these
two systems.
