Background Multiple forms of effective treatment for opioid use disorders (OUDs) exist, but they have remained in short supply and have been underutilized where available. Simultaneously, OUDs persist as a large and growing public health problem across the United States, leading to epidemic levels of overdose death as well as many other damaging societal consequences. Our goal was to assess the...

Maintenance, particularly preventive maintenance, is a crucial measure to ensure the operational reliability, availability, and profitability of complex industrial systems such as nuclear asset, wind turbines, railway trains, etc. Powered by continuous advancement sensor technology, condition-based group maintenance has become available enhance execution efficiency accuracy plans. The majority ...

The article is centred on software system development for manufacturing company that produces polyethylene bags using mostly conventional machines in a competitive world where each business enterprise desires to stand tall. This is meant to assist in gaining market shares, taking maintenance and production decisions by the dynamism and flexibilities embedded in the package as customers’ demand ...

This paper studies a maintenance policy for a system composed of two components, which are subject to continuous deterioration and consequently stochastic failure. The failure of each component results in the failure of the system. The components are inspected periodically and their deterioration degrees are monitored. The components can be maintained using different maintenance actions (repair...

Most manufacturers use human-machine systems to produce high-quality products. Dealing with human-machine systems is very complicated since not only machines should be utilized in proper condition but also appropriate environment should be provided for human resources. Most manufacturers have a maintenance plan for machines but many of them do not have a proper work-rest schedule for human reso...

power transformers provide a vital link between the generation and distribution of produced energy. such static equipment is subjected to abuse during operation in generation and distribution stations and leads to catastrophic failures. this paper reviewed the techniques in the field of condition monitoring of power transformers in recent years. transformer monitoring and diagnosis are the effe...

Abstract: A condition based preventive maintenance (CBPM) policy is proposed for a continuously operating device whose condition deteriorates with time in service. The model incorporates both deterioration and random failures. Deterioration is modeled as discrete states process. The system undergoes random inspections to know the condition, mean time between inspections are exponentially distri...

Condition based maintenance (CBM) aims to reduce maintenance cost and improve equipment reliability by effectively utilizing condition monitoring and prediction information. It is observed that the prediction accuracy often improves with the increase of the age of the component. In this research, we develop a method to quantify the remaining life prediction uncertainty considering the predictio...
