File and work transfers in cyclic queue systems

Article Abstract:

A cyclic queue model with interdependent work is introduced. A methodology for the efficient calculation of waiting and sojourn times is also presented. This procedure can be used in computing performance measures in cyclic systems with work transfer. It could also prove useful in testing the efficiency of various approximation schemes against the exact analysis. The cyclic queue model may be applied to several areas including computer file transfer, rework in manufacturing and internal mail delivery.

Delays for customers from different arrival streams to a queue

Article Abstract:

For a queue with various arrival streams, overall, the projected delay for clients of one stream is not the same as the expected delay for clients on another stream. Two approximations are given for the projected delay for clients from a specific arrival stream under a process of arrival that is a superposition of autonomous renewal applications. The two approximations produce errors under ten percent, on the average, as compared to simulation projections.

Optimal Entering Rules for a Customer with Wait Option at an M-G-I Queue

Article Abstract:

A single smart customer seeking self-optimization in an M-G-1 Queueing system is studied. The customer may enter the queue, leave the system or defer the decision. He may monitor the system and reconsider his status. The decision is based on the customer's cost-benefit analysis. Optimal strategies are discussed. Tables contain numerical results.
