Imperfect Preventive-Maintenance
IEEE Transactions on Reliability, 1979This paper considers a periodic preventive maintenance (pm) policy with ``minimal repair'' at failure; pm is imperfect. A special case of failure (hazard) rate improvement is postulated wherein pm reduces the failure rate, but does not return the time origin all the way to zero.

Industrial Lubrication and Tribology, 1974
IT is always more valuable to prevent trouble before it occurs than to experience a failure and have to break down a machine with its consequent loss of production. Industry has become very preventive‐maintenance minded in recent years and this is a field where tribological knowledge can play a large part.

Optimal Maintenance Policy with Imperfect Preventive Maintenance
IEEE Transactions on Reliability, 1981This paper considers a maintenance policy with imperfect preventive maintenance (pm). After pm, the failure characteristic of the system is different (worse) from that of correctively maintained system (viz. after a failure). Optimal policy which minimizes the mean cost-rate is discussed.

Optimum Preventive Maintenance Policies
Operations Research, 1960Two types of preventive maintenance policies are considered. A policy is defined to be optimum if it maximizes “limiting efficiency,” i.e., fractional amount of up-time over long intervals. Elementary renewal theory is used to obtain optimum policies. The optimum policies are determined, in each case, as unique solutions of certain integral equations ...

Preventive Maintenance Scheduling
International Journal of Operations Research and Information Systems, 2013In this work, the effectiveness of preventive maintenance scheduling (PMS) decisions was reported based on a techno-economic model that reflects cost objective function for ship maintenance activities. With a potential to impact on both transportation businesses and users of transportation services, the model provides an alternative to the combined ...

Geriatric Preventive Health Maintenance
Journal of the American Geriatrics Society, 1980ABSTRACT A preventive approach to geriatric health care should include periodic and systematic assessment of the physical, mental and social status of the elderly person. This article is a review of the important aspects of geriatric health maintenance and calls for more American data from the ambulatory‐care setting, to aid in ...
