摘要：We consider a production/inventory system consisting of M machines and K (K less than or equal toM) repair crews in which machines are subject to time-dependent failures. The repair operations an each machine require one repair crew during the whole operation. In this production/inventory system, each machine is assigned to produce a different item according to a make-to-stock routine. Inventories of each item service a Poisson demand process, and the unsatisfied demands are lost. The objectiv...

摘要：Given that the total service effort in a multiple-server environment is fixed, it is generally known that the single-server system yields the minimum time a customer spends in the system. However, in many manufacturing as well as service applications the waiting time in the queue is more significant than total time in the system. We consider several such queueing design problems and show that the results for minimizing the waiting time in the queue are markedly different from those for minimiz...
