Allocation of Service Time in a Multiserver System
El-Taha, Muhammad; Maddah, Bacel - In: Management Science 52 (2006) 4, pp. 623-637
Reducing congestion is a primary concern in the design and analysis of queueing networks, especially in systems where sources of randomness are characterized by high variability. This paper considers a multiserver first-come, first-served (FCFS) queueing model where we arrange servers in two...

Sea Container Terminals
Gharehgozli, Gharehgozli, A.H.; Roy, Roy, D.; de … - Erasmus Research Institute of Management (ERIM), … - 2014
Due to a rapid growth in world trade and a huge increase in containerized goods, sea container terminals play a vital role in globe-spanning supply chains. Container terminals should be able to handle large ships, with large call sizes within the shortest time possible, and at competitive rates....

A Fluid Flow Model of Networks of Queues
Vandergraft, James S. - In: Management Science 29 (1983) 10, pp. 1198-1208
This paper describes a new technique for modeling flow through a network of queues. The advantages of this method over many discrete event simulations or queueing theory techniques include simplicity, low cost and portability. The paper describes the kinds of processes to which the technique can...
