The objective of this course is to acquaint the student with some probabilistic modeling approaches at the micro-scopic level. Applications are mainly focused on the service systems.

讲座题目:Information and Pricing Effects in Two-tier Public Service Systems

摘要:

Public service such as healthcare may be offered by both free (public) and toll (private) service providers. Such a system, called a two-tier service system, is usually subject to congestion and often modeled as two parallel queues. Customers can choose one of three options: joining the free system, joining the toll system, and balking based on the congestion in each service system and the toll price. This paper examines the effects of congestion information and price of the toll system on the system performance of the two-tier service system. We consider the performance measures from three different perspectives of customers, toll service provider, and social planner, respectively. Two information scenarios are compared. The first scenario, called a mixed information case (MI), is the one where the free system does not offer real time queue length information but the toll system does. The second scenario, called a non-real time information case (NRI), is the one where both systems do not offer real time queue length information. We propose Markovian queueing models to analyze the system performance. Several computational algorithms are developed based on the matrix analytical method. Numerical analysis is performed to generate important managerial insights for decision makers. It is found that the information effect depends on the price range and it can either improve or hurt some performance measures. Furthermore, the optimal pricing decisions for different performance measures (customer, service provider, and social planner) are different.
