Routing and Staffing when Servers are Strategic

In a service system, the routing and staffing policies control such workload incentives; and so the rate servers work will be impacted by the system's routing and staffing policies. ...
Then, within the class of policies that admit an equilibrium, we (asymptotically) solve the problem of minimizing the total cost, when there are linear staffing costs and linear waiting costs. ...

In this paper we consider the problem of work order (WO) arrivals and time spent on work orders in service delivery to derive the asymptotic behavior of a strategic outsourcing contract. ...
We use the resulting model to derive the probability that a contract will exceed the allocated budget for resolving work orders, and also to calculate the staffing requirement for resolving work orders ...
The area of optimal staffing with skill based routing is a mature area. Analytical methods are typically complex and do not capture full generality of real IT service delivery systems. ...

Despite the apparently unrealistic assumption of infinite resources, infinite-server queueing models have played a central role in the development of queueing theory and its applications. ...

However, randomness in the number of servers often arises in practice, particularly when the servers themselves may be viewed as strategic decision makers, e.g., in virtual call centers or ride-sharing ...
In this paper, we study the problem of staffing many-server queues with generally-distributed customer abandonment and a random number of servers. ...
Recent exceptions are Gopalakrishnan et al. (2015) and Zhan and Ward (2015) who study, respectively, optimal routing and staffing decisions, and optimal compensation schemes in many-server queueing ...

Established agent-staffing and SBR algorithms ensure that agents have the required call-handling skills and that call routing is performed so that constraints are met for standard congestion measures, ...
Since customer service representatives (agents) have different call-handling abilities and are typically cross-trained in multiple skills, contact centers exploit skill-based routing (SBR) to assign calls ...
At this point we are concerned with routing for given staffing and given priority matrix P .
The Routing Algorithm Given the priority matrix P , we can specify the routing algorithm. ...
