This paper presents a mathematical model for an inventory control system in which customers' demands and suppliers' service time are considered as stochastic parameters. The proposed problem is solved through queuing theory for a single item. In this case, transitional probabilities are...

Purpose: Nowadays, governments and people pay more attention to use green products due to environmental pollution, irreplaceable energy and shortage of resources. Green products are resulted from the application of green supply chain management strategies to the organizations' performance...

Abstract In an influential paper, Choi and Kim (2010) established the invariance result that given a fixed network capacity, the average waiting times are identical regardless of net neutrality. In this paper, we argue that their result relies on the assumption that the distribution for content...

Abstract This paper examines the effect of prioritization on competing CPs’ incentives to invest to improve their quality of service (QoS). We show that in the single-homing case, no CP makes a positive amount of investment under net neutrality because the effect of reducing delay is shared by...

This paper analyzes the effects of net neutrality regulation oninvestment incentives for Internet service providers (ISPs) and contentproviders (CPs), and their implications for social welfare. We show thatthe ISP s decision on the introduction of discrimination across contentdepends on a...

This paper analyzes the effects of net neutrality regulation on investment incentives for Internet service providers (ISPs) and content providers (CPs), and their implications for social welfare. We show that the ISP's decision on the introduction of discrimination across content depends on a...

This thesis focuses on increasing the efficiency of systems with cross-trained workforce and finite storage spaces. Our objective is to maximize the throughput and minimize the setup costs (if they exist). More specifically, we are interested in determining effective cross-training strategies...

This dissertation deals with three problems in health care. In the first, we consider the incentives to change prices and capital levels at hospitals, using optimal control under the assumption that private payers charge higher prices if patients consume more hospital services. The main results...

This paper uses queuing theory to examine the linkages between legal and illegal immigration. This approach is particularly appropriate for periods of mass migration and can be used to look at how the magnitude of people trying to migrate affects the choice between legal and illegal channels. An...

This paper addresses the problem of an unacceptably high rate of abandoned calls at a centralisedservice desk of a South African telecommunications company. It uses a queuing methodology todesign a system that may achieve the desired performance level. A quality standard is created bydetermining...
