The objective of this paper is to study the M/M/R machine repair queueing system with mixed standbys. The life-time and repair time of units are assumed to be exponentially distributed. Failed units are repaired on FCFS basis. The standbys have switching failure probability q (0≤q≤1). The repair facility of the system consists of R permanent as well as r additional removable repairmen. Due to i...

Speaker: Jim Dai Title: Maximum Pressure Policies in Stochastic Processing Networks Abstract: Stochastic processing networks have been introduced in a series of three papers by Harrison (2000, 2002, 2003). These networks are much more general than multi-class queueing networks. The added generality allows one to model skill-based routing in call centers, operator-machine interactions in semicon...

Advances in information technology increasingly allow firms to identify expensive, high-cost customers, who are not only individually less profitable for firms but also raise the average marginal cost incurred by firms and thus impose a negative externality on inexpensive customers. Should competing firms share information that identifies such customers? The answer to this question has importan...

Lead in large part by Charter 88 and the Scottish Constitutional Convention, the activities of the constitutional reform movement since the early 1990s have clearly helped to introduce new proportional voting systems into UK politics. Yet, at the same time, the Labour governments after 1997decisively rejected voting reform for the House of Commons and dragged out Lords reform to prevent any dir...

a r t i c l e i n f o The Internet has provided great convenience for online shoppers and has presented unprecedented opportunities for online retailers to understand their customers. Getting the pricing right has emerged as one of the ultimate keys to the success of electronic commerce. Although some online retailers have tried some person-alized pricing strategies for perishable capacity or i...

When bids do not represent binding commitments, the use of a …rst price sealed bid auction favors those bidders who are less penalized from reneging on their bids. These bidders are the most likely to win but also the most likely to default on their bid. In this paper I study theoretically two methods often used in public procurement to deal with this problem: (1) augmenting the …rst price auct...
