Condition-based maintenance

anywhere, unlike traditional planes. Along with providing lift, helicopter main rotors are the source of destructive vibrations that can severely damage the aircraft, if not dealt with properly. Helicopter track and balance, or rotor smoothing is a maintenance procedure done to minimize airframe vibrations that consequently cause cracks, crew fatigue, and premature component failure. Track and balance is both time consuming and expensive, so improvements to the process have been what many technicians

the importance of maintenance. But still a lot more improvement is necessary in maintenance area. Most of the companies are still thinking maintenance as a separate additional department. This paper outlines different maintenance policies with their benefits and limitations. It also defines the relationship between maintenance and quality by emphasizing the importance of Condition Based Maintenance (CBM) and e-maintenance. This paper also elaborates how Total Productive maintenance (TPM) changes the

environmental and operating conditions (British standard, 2012). Reliability is the probability that the system is operating satisfactory at any given time and it depends on the reliability and the

Rehabilitation and Maintenance programs are complex in nature as the treatments vary depending on pavement condition index and pavement type. Funding is derived from a variety of sources, including Road Use Tax, Local Options Sales Tax and General Obligation Bonds. A portion of available funds is dedicated to year round preventive maintenance activities to extend the life of paved surfaces; remaining available funds is used to repair and rehabilitate roads. A variety of preventive maintenance techniques

Maintenance plays a relevant role in business success related to offshore oil and gas. It is a key for ensuring the efficient use of equipment as well as an efficient production process and, hence on the profitability since failures impacts the performance of subsea equipment both in terms of production accessibility and repetitive breakdowns or running in bad condition may contribute to lower product quality, increased energy consumption and reduced revenue. Thus, the objective of maintenance is

III . COMPONENTS OF E-MAINTENANCE There are ten different components which are necessary to understand e-maintenance Fig. 2 Components of E-maintenance [3] • Business and Organization: It is expected that e-maintenance will maintain the balance between customer, product and supplier. E-maintenance will make sure that daily activities of organization has been run without any interruption and customer will receive the product at right time[3]. • Product, Services , Information

the ‘Slope Repairs’ maintenance activities. a) Changes in scope of work– Scope increases. b) Drainages, shoulder work has to increases. c) Less time to prepare estimate. d) Extend of slope failure is not exactly same as what mentioned in the original contract. i.e. the problem in the site is not same as that mentioned in the contract. e) More deterioration at the time of repair work as compared the time of estimation. f) The slope conditions worsen more while doing maintenance works. The slide might

incremental facility deterioration model on bridge deck sample. Since infrastructure moves from one transitional state to another with a set probability associated with the transition process, with the help of explanatory variables predicts the changes in condition of infrastructure over a period using the incremental models. The data used in this case is panel data. The previous research that has been done in this area does not account for the effects of heterogeneity in panel data. Due to the presence of

In this study, a tool was developed to estimate contingency cost for a maintenance contract based on historical records of the CO on the road maintenance activities. In order to develop the tool, the Visual C# and the R-program were selected as development platforms. As historical data, 614 road maintenance contracts were received from Kenya Rural Road Authority (KeRRA) in Kenya. These data were used for the validation of the tool developed during this study. The steps that were required to develop

availability and at the same time meet the cost and regulatory requirements, it was contended that appropriate maintenance strategies need to be integrated with other management functions (Nakajima,1989). The plant must always be in the optimum operation condition to improve its availability and reliability in the network. This requires that equipment design ensures maintainability so as to support maintenance practices (Eti, 2006). If maintainability is achieved then organizational performance would be enhanced
