This paper presents a systematic approach for bridge maintenance management that combines a stochastic Markovian performance prediction model with a multi-objective optimization procedure to determine the optimal allocation of funds and prioritization of bridges for maintenance, repair and replacement (MR&R). The prioritization of the bridges is based on the satisfaction of several conflicting ...

In the last 30 years, China has achieved high economic growth and successfully transformed its economy from a planned economy to a market-based system. The country, to a large extent, has attained success through the recommendations proposed by standard economic theory. However, the role of political economy has been omitted from the literature: how did China adopt the right economic policies a...

goals prioritization, mental health and irrational beliefs are concept much discussed nowadays. this study aims to compare the goals prioritization of the students and its relation to mental health and irrational beliefs. this study was designed and completed descriptively. the sample included 216 students of allamehtabatabai university. students completed the goals and aspirations, mental heal...

Background Networks have been proven effective representations for the analysis of biological data. As such, there exist multiple methods to extract knowledge from biological networks. However, these approaches usually limit their scope to a single biological entity type of interest or they lack the flexibility to analyze user-defined data. Results We developed ProphTools, a flexible open-sou...

Regression testing is carried out to test the updated supply code within constraints of time and sources. Since it very difficult run all source every time, case prioritization needed decrease fee regression testing. Various methodologies including extensions white box black prioritization, have been presented considering instances. In this context, employment particle swarm optimization (PSO) ...

OBJECTIVES To outline the methods used to build a discrete-event simulation model for use in decision-making in the context of waiting list management strategies for cataract surgery by comparing a waiting list prioritization system with the routinely used first-in, first-out (FIFO) discipline. METHODS The setting was the Spanish health system. The model reproduced the process of cataract, fr...

OBJECTIVES To describe the creation of an Emergency Medical Services for Children (EMSC) research agenda specific to multicenter research. Given the need for multicenter research in EMSC and the unique opportunity afforded by the creation of the Pediatric Emergency Care Applied Research Network (PECARN), the authors revisited existing EMSC research agendas to develop a PECARN-specific research ...

The dominant American social movement scholarship has become detached from the concerns of actual social movements. But the dramatic growth of social movement activity in recent years, especially the global justice movement, is creating the conditions for an emerging new direction in social movement scholarship which prioritizes the relevance of such work to the movements themselves. A problem ...

Building maintenance management involves decision-making under multiple objectives and uncertainty, in addition to budgetary constraints. This paper presents the development of a multiobjective and stochastic optimization system for maintenance management of roofing systems that integrates stochastic condition assessment and performance prediction models with a multiobjective optimization appro...
