We model a system which consists of a stream of customers processed through three steps by two resources. The first resource, an investigator, handles the first step, in which she collects information from the customer and decides what work will be done in the second step by the second resource,...

Purpose: To demonstrate a simple mathematical model for evaluating operational decisions for preparing compounded sterile products in a hospital pharmacy.Summary: This paper describes a simple mathematical model, based on a small set of parameters easily estimated from existing data. This model...

We give sufficient conditions under which a policy that assigns customers to the Fastest Available Server, labelled FAS, is optimal among non-idling policies in queuing models with multiple independent Markov-modulated Poisson arrival processes and heterogeneous parallel exponential servers with...
