Process-driven spreadsheet queuing simulation is a better vehicle for understanding queue behavior than queuing theory or dedicated simulation software. Spreadsheet queuing simulation has many pedagogical benefits in a business school end-user modeling course, including developing students' intuition , giving them experience with active modeling skills, and providing access to tools. Spreadshee...

Monitoring animal welfare at a slaughterhouse is somehow different from the situation on the farm. The throughput numbers can be very high, and there is no possibility to know the individual history, background or habits of each animal. The animals are unfamiliar to the staff and viceversa. Furthermore, most animals will be unknown to each other even if they may be delivered in groups or batche...

This paper studies alternative ways to manage a multi-server system such as a telephone call center. Three alternatives can be described succinctly by: (i) blocking, (ii) reneging and (iii) balking. The rst alternative { blocking { is to have no provision for waiting. The second alternative is to allow waiting, but neither inform customers about anticipated delays nor provide state information ...

In many service systems arising in OR/MS applications, the servers may be temporarily unavailable, a fact that affects the sojourn time of a customer and his willingness to join. Several studies that explore the balking behavior of customers in Markovian models with vacations have recently appeared in the literature. In the present paper, we study the balking behavior of customers in the single...

In many congestion problems, the customers may not like to join a long queue and may balk. To reduce the balking behavior of the customers, the provision of additional servers can be made in such situations. In the present paper, we investigate a Markovian queueing model with balking, interdependent rates and additional servers under no passing constraint. Due to nopassing restriction, the cust...
