customer satisfaction level depends on level that his expectations would be answered. with identifying customer expectations and implementation them in qfd, this ensures that important and critical demands of customer have been considered. qfd have been used and use for translating customer expectations to different subjects. what has been considered in this study, is qfd usage for translating ...

The research issues in the assessment of quality of health care have not changed significantly during the past 20 years. What was changed is the increased interest among providers, consumers, and policymakers for ways to measure and compare quality among providers. Clearly there is an increased sense of urgency in the need for research in such areas as the development of improved measures of ph...

We study the problem of priority inversion in distributed real-time and embedded systems and propose a solution based on a distributed version of the priority inheritance protocol (PIP). Previous approaches to priority inversions in distributed systems use variations of the priority ceiling protocol (PCP), originally designed for centralized systems as a modification of PIP that also prevents d...

In the U.S., the growth of the organ transplantation waiting list significantly outpaces the supply of donated organs. Among the many initiatives aiming to boost the supply, the donor priority rule, under which a registered organ donor—in case of needing a transplant—is given priority to receive an organ over a nondonor, has been considered by policy makers in the U.S. In this paper, we model t...

Priority queues have a great importance in the study of computer communication networks in which different types of traffic require different quality of service standards. The discrete-time non-preemptive priority queuing model with priority jumps is proposed in this paper. On the basis of probability generating functions mean system contents and mean queuing delay characteristics are obtained....

Packet scheduling is key to quality of service (QoS) capabilities of broadband wired and wireless networks. In a heterogeneous traffic environment, a comprehensive QoS packet scheduler must strike a balance between flow fairness and access delay. Many advanced packet scheduling solutions have targeted fair bandwidth allocation while protecting delay-constrained traffic by adding priority queue(...

Multimedia applications are expected to guarantee end-to-end quality of service (QoS) and are characterized by stringent constraints on delay, delay-jitter, bandwidth, cost, and so forth. The authors observe that Kruskal’s algorithm is limited to minimal (maximal) spanning unconstrained tree. As such, the authors extend Kruskal’s algorithm to incorporate the delay bound constraint. Consequently...

Recent developments in sensor networking for both military and civilian applications emphasized the need for a reliable integration of sensor networks with the Internet. For sensor networks deployed in various military applications, it is important that collected information be delivered as fast as possible with minimum delays. In this paper, an integration module is proposed. The objective of ...
