Telephone call centers are an integral part of many businesses, and their economic role is
significant and growing. They are also fascinating sociotechnical systems in which the …

Abstract Throughout its history, Operational Research has evolved to include methods,
models and algorithms that have been applied to a wide range of contexts. This …

Abstract Information flow in a telecommunication network is accomplished through the
interaction of mechanisms at various design layers with the end goal of supporting the …

Power grids, flexible manufacturing, cellular communications: interconnectedness has
consequences. This remarkable book gives the tools and philosophy you need to build …

We consider a queueing system with multitype customers and flexible (multiskilled) servers
that work in parallel. If Qi is the queue length of type i customers, this queue incurs cost at …

This paper considers jointly optimal design of cross-layer congestion control, routing and
scheduling for ad hoc wireless networks. We first formulate the rate constraint and …

We study a model of controlled queueing network, which operates and makes control
decisions in discrete time. An underlying random network mode determines the set of …

We consider scheduling and resource allocation for the downlink of a cellular OFDM system,
with various practical considerations including integer tone allocations, different sub …

In this paper, we present a new perspective on flexibility in manufacturing and service
operations by exploring a type of operational flexibility that we term “structural flexibility …

We consider the following queuing system which arises as a model of a wireless link shared
by multiple users. There is a finite number N of input flows served by a server. The system …
