Special Session

Multistate Network Reliability with Applications

Organizer:

Chair Professor Yi-Kuei Lin (National Taiwan University of Science & Technology, Taiwan; yklin[at]mail.ntust.edu.tw)

In the past decades, a great deal of research has been devoted to studying multistate network modeling and its reliability evaluation. A system with multistate capacity levels ranging from a perfectly working level to complete malfunction can be modeled as a multistate network. Due to failure, partial failure, and maintenance, many real-life systems such as computer, project, transportation, manufacturing, and logistic systems can be modeled as multistate networks. The fact that uncertainties and randomness are accompanied with almost all real-life systems, efforts on multistate network are essential.

From the decision making perspectives, reliability is one of the key performance indicators (KPI) to assess the stability and robustness of a multistate network. Based on the reliability, system supervisors can improve or investigate the most important part for multistate networks. In order to achieve a balance between theoretical material and practical applications, case study of real-life multistate networks and engineering-related applications are crucial tasks. Hence, theoretical studies and practical applications on multistate network reliability are both addressed in this special session.

In this special session, we focus on the “Multistate Network Reliability with Applications”, and invite related high quality papers from both aspects of theory and practice.
