In this paper, a single-product, single-machine system under Markovian deterioration of machine condition and demand uncertainty is studied.  The objective is to find the optimal intervals for inspection and preventive maintenance activities in a condition-based maintenance planning with discrete monitoring framework. At first, a stochastic dynamic programming model whose state variable is the ...

BACKGROUND AND OBJECTIVES Prevention is a challenging area of primary care. In Switzerland, little is known about attitudes to and performance of screening and prevention services in general practice. To implement prevention services in primary care it is important to know about not only potential facilitators but also barriers. Primary care encompasses the activities of general practitioners, ...

Joint optimization models were developed combining group preventive maintenance of a series system and production scheduling. In this paper, we propose a joint optimization model to minimize the total cost including production cost, preventive maintenance cost, minimal repair cost for unexpected failures and tardiness cost. The total cost depends on both the production process and the machine m...

BACKGROUND To explore the factors predicting preventive behaviours among NHS dentists in Camden, Islington and Haringey in London, using constructs from the Theory of Planned Behaviour. METHODS A cross-sectional survey of NHS dentists working in North Central London was conducted. A self-completed questionnaire based on the theoretical framework of the Theory of Planned Behaviour was develope...

This paper reviews some of the evidence of success for preventive dentistry in the global context and presents some challenges for preventive dentistry in the coming years. Rather than attempting a detailed analysis of individual countries the global view looks at trends and patterns of prevention, care and disease in the context of demographic and other societal changes. In citing examples fro...

In this paper, we consider a production system that must achieve a set of different requests during a finite horizon period. Among the various requests proposed, the objective is to select those to be satisfied so as to maximize the net profit. A sporadic maintenance policy is studied to minimize the maintenance costs by the achievement of perfect preventive maintenance actions after the comple...

Cleaning and disinfection protocols are not always able to remove biofilm microbes present in breweries, indicating that novel anti-biofilm strategies needed. The preventive activities of three...

This paper presents a condition-based maintenance policy taking into account both maintenance cost and production capacity aspects for single unit deterioratin production system whose condition is periodically monitored. Imperfect preventive maintenance activities, which restore the production system to better states and might not be as good as new, are considered. We assume however that the sy...

background and aims : the harms resulted from home injuries are a major factor in child mortality. the current study aims to evaluate the factors associated with the knowledge and performance level of mothers in terms of adopting preventive behaviors to avoid home injuries. materials and methods : the target population of this descriptive - analytical study is all mothers of preschool children ...
