Network reliability evaluation is important for the planning, design and control of arbitrary systems. A novel set theory based method for deriving terminal reliability expressions of complex system configurations is described in this paper. The reliability formula of a networked system is expressed as sum of disjoint products, where the product terms represent conjunctions of Boolean variables...

Transportation planning research has been fundamentally transformed by the advancement of spatial cyberinfrastructure (CI) and other planning information technologies. This is no better exemplified than by the evolution of online transit trip planning systems. This paper describes the progression of online transit trip planning systems as a result of innovations in cyberinfrastructure, from the...

Next, the problems in the optimal planning for a stand-alone microgrid system are summarized, including the unique operational ...

Reliability is one of the highly significant quality indicators of object oriented software. Its proper measurement or evaluation, constantly facilitate and improve the software development process. On the other hand, reliability has always been a mysterious theory and its truthful measurement or evaluation is a complex exercise. Researchers and practitioners have always argued that reliability...

Economic growth in China is accompanied by many problems, such as rapid deterioration of the environment and a sharp decline in the area of arable land. China’s current land-use planning system fails to deal with these problems, especially at the regional level. The lack of sustainable spatial allocation at regional level has become a pressing problem. This article aims to: (1) analyze the reas...

in recent years, significant research efforts have been devoted to the optimal planning of power systems. substation expansion planning (sep) as a sub-system of power system planning consists of finding the most economical solution with the optimal location and size of future substations and/or feeders to meet the future demand. the large number of design variables, and combination of discrete ...

We study dynamic reliability of systems where system components age with a constant failure rate and there is a budget constraint. We develop a methodology to effectively prepare a predictive maintenance plan of such a system using dynamic Bayesian networks (DBNs). DBN representation allows monitoring the system reliability in a given planning horizon and predicting the system state under diffe...

In recent years, simulation has become an essential tool for planning, designing, and managing terminal operations. Simulation modeling of various aspects related to the dynamic nature of the pedestrian/passenger behavior within a transport terminal can effectively assist in the analysis, evaluation, emergency response planning, and decision support phases of the terminal’s operation. In this p...
