As countries strive toward universal health coverage, mobile wireless technologies-mHealth tools-in support of enumeration, registration, unique identification, and maintenance of health records will facilitate improved health system performance. Electronic forms and registry systems will enable routine monitoring of the coverage of essential interventions for individuals within relevant target...

In this paper we propose several human-machine strategies for decision support, the central thesis being relying on purely human ability or blindly on decision support mechanisms results in ineffective and inefficient decisions in most situations. The need for strategies that effectively and efficiently combine human decision ability with those of computer systems is of pivotal concern. A sugge...

The ability to monitor the condition of an electrical machine has been a concern of industry for many years. Knowing when a machine requires maintenance allows users to perform the required maintenance at their convenience, rather than during costly unscheduled shutdowns. This need for improved industrial monitoring techniques has produced a number of studies on the detection of mechanical faul...

The Alarm Processing System reference model for large-scale railway maintenance equipment diesel engine combustion control, which is based on multi-agent, is an important system for high speed and automation. Alarm Processing System are vital aspects in M large-scale railway maintenance equipment diesel engine combustion control, in this sense, alarm processing system should support decision-ma...

this paper discusses the performance evaluation and availability analysis of ammonia synthesis unit of a fertilizer plant. the fertilizer plant is a complex and repairable engineering system comprises of various units viz. shell gasification and carbon recovery, desulphurization, co-shift conversion, decarbonation, nitrogen wash and ammonia synthesis etc. one of the most important functionaries...

Sensors and sensor-rich embedded systems are eminently applicable for autonomous monitoring and control in noncommercial, home or professional environments, besides their increasing use in medical and ecological settings, or mainstream use in industrial control. Having end users realize, deploy and interact with sensor-based embedded systems is conditioned, among others, by the availability of ...

We consider a make-to-stock production/inventory system consisting of a single deteriorating machine which produces a single item. We formulate the integrated decisions of maintenance and production using a Markov Decision Process. The optimal dynamic policy is shown to have a rather complex structure which leads us to consider more implementable policies. We present a double-threshold policy a...

Abstract. Current approaches to maintenance of rolling stock bogies are focused on compliance wear limits as stipulated by OEM specifications. recommendations critical providing an industry wide approach safety and compliance. These not operation specific often the most cost-effective solutions. A system reliability is established that applied in less complex systems where relationships between...
