FURTHER RESULTS ON AN INFINITE CAPACITY SHUTTLE WITH CONTROL AT A SINGLE TERMINAL

OPERATIONS RESEARCH 1981年第6期29卷 1212-1217页

作者： WEISS, HJ Temple University Philadelphia Pennsylvania

The infinite capacity shuttle system that is described by Ignall and Kolesar [1974] is considered. Passengers arrive at each of two terminals according to independent Poisson Processes. The vehicle can be held at only one of the terminals. When the vehicle is dispatched it transports all of the passengers waiting at terminal 1 to terminal 2, immediately picks up the passengers at terminal 2 and returns to terminal 1. It is known that under general conditions the optimal vehicle dispatching policy is a control limit policy: Dispatch the shuttle if and only If the number of passengers waiting at both terminals is at least as large as some cutoff value. In this paper a method for computing the optimal cutoff value is presented. In addition we examine the savings that result when using a control limit policy rather than the more traditional policy of scheduled periodic service. Last, we prove a conjecture by Signally and Kolesar regarding the optimal policy for instances when the dispatcher does not know the number of passengers waiting at terminal 2.

We consider a multiple-server loss model where customers arrive at a gatekeeper according to a Poisson process. A cost c is incurred if a new arrival is blocked from entering the system by the gatekeeper, while a larger cost K is incurred if an admitted customer finds all servers busy and therefore has to leave the system. The key assumption is that the gatekeeper is informed when an admitted customer finds all servers busy, but is not informed when served customers depart. Assuming an exponential service distribution, we show that, in the case of a single server. a threshold-type policy that blocks for a certain amount of time after a new arrival is admitted is optimal. When there are multiple servers, we propose two types of heuristic policies. We analytically compute the best policy of the first type, and use simulation to estimate that of the other.

MARKOV DECISION-PROCESSES WITH A BOREL MEASURABLE cost FUNCTION - THE average CASE

引用

MATHEMATICS OF OPERATIONS RESEARCH 1986年第2期11卷 309-320页

作者： KURANO, M CHIBA UNIV FAC EDUCDEPT MATHCHIBA 260JAPAN

We consider a Markov decision process with a Borel measurable cost function. We introduce a v-step contraction property for the average cost case. By use of this method, the validity of the optimality equation and the existence of ε -optimal stationary policies are proved. As some applications, the sequential replacement model and the inventory model are considered.

Project outcomes: Evaluating predicted benefits for field force mobilization

JOURNAL AMERICAN WATER WORKS ASSOCIATION 2013年第2期105卷 54-57页

A year into launching a production mobile workforce automation system, Denver Water reviews benefits that were not quantified with its initial analysis and presents compelling reasons for continuing to build on the system. This article is part three of a series about this experience. The first article, in the August 2012 Journal (Assessing Options and costs Versus Benefits of a Mobile Work Management Solution), outlined the start of the journey to build this application with a focus on creating a compelling yet conservative cost-benefit analysis (CBA) for a new mobile work management system. The second article, in the November 2012 Journal (Information Technology Projects and Business Engagement: New Strategies), focused on how system adoption and end-user satisfaction were achieved through an agile software development process.
