Both definitions refer to the system and maintaining the functionality of the system 3 Definitions • Maintainability: The ability of an item, under stated conditions of use, to be retained in, or restored to, a state in which it can perform its required function(s), when maintenance is performed under stated conditions and using prescribed procedures and resources. Expressed as Mean Time To Repair (MTTR).
• Availability: Is the probability that a system is available for use at a given time- a function of reliability and maintainability. It is perating time divided by load time, which is the available time per day minus the planned downtime . • Failure: The termination of the ability of an item to perform its required function. 4 2 Inherent Availability Ai = MTBF MTBF + MTTR Inherent availability considers only corrective maintenance in an ideal support environment (with neither administrative nor logistic delays. When equipment is in a failed state it is no longer available for work, and its reliability decreases. As the length of time in a failed state (downtime ) increases, the maintainability of the equipment decreases.

Current knowledge of predictive, analytical, and compliance technologies, and the ability to apply these techniques to add value to the firm. 2. The adaptation and application of concepts such as TPM and RCM. 3. The development and implementation of a proactive M&R plan(s) to eliminate maintenance requirements, minimize the use and costs of reactive maintenance, maximize the benefits of PM and PdM, and achieve increasing levels of integrated asset management. 4. The ability to lead or technically support multidisciplinary teams.
The Business plan on Financial Planning In An Engineering Business
Financial planning is a dynamic process that deals with allocation of various financial resources in order to meet strategic goals and objectives of the business. Financial planning involves planning for finance and planning for operations. Operation managers are concerned with sales and production whereas financial planners are interested in financing the operations nevertheless financial ...
