We study a stochastic network that consists of a set of servers processing multiple classes of jobs. Each class of jobs requires a concurrent occupancy of several servers while being processed, and each server is shared among the job classes in a head-of-the-line processorsharing mechanism. The allocation of the service capacities is a real-time control mechanism: in each network state, the res...

Purpose This study aims to analytically explore the economic role of transfer pricing in a vertically integrated supply chain with direct channel, specifically when it uses cost-based prices, as is frequently observed management practices. We compare two representative methods: full-cost and variable-cost pricing. Although many firms open which affects optimal decision on prior literature has n...

We consider a single node which multiplexes a large number of traffic sources. We are concerned with the amount of buffer and bandwidth that should be allocated to a class of i.i.d. on/off fluid flows. We impose a maximum overflow probability on the class, and assume that the aggregate flow can be modelled using effective bandwidth. Unlike previous approaches which assume that the total buffer ...

We consider a single buyer who wishes to outsource a fixed demand for a manufactured good or service at a fixed price to a set of potential suppliers. We examine the value of competition as a mechanism for the buyer to elicit service quality from the suppliers. We compare two approaches the buyer could use to orchestrate this competition: (1) a Supplier-Allocation (SA) approach, which allocates...

This paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. System engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (TCO...

Dynamic channel resource allocation (DCA) exploiting wideband multiuser diversity can provide data transmission with very high spectral efficiency by scheduling at each dimension (time, frequency, space) the user with the best channel conditions. The main issue arising from this allocation is fairness. Base station or users have to wait until their channel is most favorable to transmit. It is c...

Health systems around the world are grappling with the difficult issue of how to allocate scare healthcare resources. Within Europe many different approaches to healthcare resource allocation exist, but it is clear that the formal techniques of cost-effectiveness analysis are becoming increasingly important. This presentation will first address the fundamental economic principles of scarcity an...

Despite the growing use of decision analytic modelling in cost-effectiveness analysis, there is a relatively small literature on what constitutes good practice in decision analysis. The aim of this paper is to consider the concept of 'validity' and 'quality' in this area of evaluation, and to suggest a framework by which quality can be demonstrated on the part of the analyst and assessed by the...
