Preventive Maintenance Approach Maintenance has changed over the past 30 years. This is due to a huge increase in the number and variety of physical assets that must be maintained, more complex designs, new maintenance techniques and changing views on maintenance organisation. Reliability-Centred Maintenance (RCM) has played a central role in the evolution of maintenance strategies. In the past, preventive maintenance was considered the most advanced and effective maintenance technique available. A Preventive Maintenance (PM) program would assume a cause-and-effect relationship between scheduled maintenance and operating reliability.
The definition of maintenance objectives can be viewed as a max / min principle - maximizing the output of maintenance that meets the technical accuracy of the equipment, minimizing inputs for maintenance in terms of the number of employees, financial resources and costs in general. The most important thing is that all input factors interact with each other, considering that relatively small changes in any of the input factors can significantly affect the output or the working ability of the equipment. There are many concepts of maintenance and improvement strategies such as: TPM - total productive maintenance, RCM - reliability centred maintenance, RBI - risk based inspection, LCC – life cycle costing, CMMS - computerized maintenance management software, maintenance management, spare parts management etc. Problems arise when organizations use more than one concept simultaneously and start a new project in the middle of unfinished work, leading to the dissatisfaction of all participants in the project. The situation becomes even more complicated if the organization changed targets to improve maintenance from using increasing equipment effectiveness (reliability and availability) to reduce costs and vice
Preventive maintenance may be a daily maintenance (cleaning, inspection, oiling and re-tightening), designed to retain the health condition of equipment and prevent failure through the prevention of deterioration, periodic inspection or equipment condition diagnosis, to measure deterioration. The intent for preventive maintenance is to prevent maintenance problems or failure before they take place by following routine and comprehensive maintenance procedures. The goal is to achieve fewer, shorter and more predictable outages. Advantage of preventive maintenance • Costs are distributed more evenly. • Easier planning of maintenance and ordering spares.
Often maintenance activities (including preventive maintenance (PM) and corrective maintenance (CM)) are outsourced to an OEM (original equipment manufacturer) or an external agent. OEM or an agent can do a partial or full coverage of the maintenance actions (Preventive Maintenance (PM) or/and Corrective maintenance (CM)). Preventive maintenance (PM) actions are done to prevent the excessive degradation (whether it is an age based or condition based maintenance), while corrective maintenance (CM) is performed to restore the failed equipment to the operational state. In general, OEM or an agent offers various maintenance service contracts to meet the requirement of a mining
It is not uncommon for projects to lead to serious and costly (technical, financial or commercial) failures, to a degradation or questioning of their main objectives (costs, deadlines and performance), or even to their pure and simple abandonment. Managing Project Risks is so important that Governments and businesses take it seriously so they can reduce the cost of their infrastructure investments by more than $5 trillion by 2030 if they improve how they manage the risks inherent in large projects (Wyman, 2012). That is why Managing Project Risks has become important, even a major concern for many project managers in recent years. To carry out the project according to the forecasts, it is essential to set up a risk management in order to look for the weak points in order to think and consider the solutions to the actions to prevent the risks. Risk management attempts to recognize and manage potential and unforeseen trouble spots that may occur when the project is implemented (Erik W. Larson).
It includes both preventive maintenance and failure fining tasks. It puts emphasis on the consequence of failure of the component. Maintenance Philosophies 1. Hard Time limit: Scheduled removal of the item before it crosses its maximum permissible age limit 2. On-Condition: Scheduled inspection or test of the unit to determine whether the item will work in a satisfactory manner till the next inspection or test.
(Allen, 2009). The maintenance management is include many type of operation and function to keep the building to ensure the building achieve the building standard that provided by local authority. In order to achieve the standard one of the planning by strategy, strategy is the efficient design of a structure requires an understanding of how it is
6.0 MAINTENANCE Maintenance is the activities involved in keeping a machine or equipment in working condition to ensure the efficiency is retained and its life is increased. Maintenance is not only refer to repair the broken or destroyed equipment rapidly but is a management to keep those machines and equipments running in high capacity and produce products with high quality at low cost. Having high quality equipment will lead to high reliability and maintainability which ensure the organization’s productivity and equipment with high efficiency. Good maintenance and reliability management requires employee involvement and good procedures. By using reward system, providing skill training or employee empowerment in maintenance can help to improve
You have to make sure that they 're working all the time, right? A planned maintenance is vital in ensuring that they won 't fail when you need them. • Avoids High Emergency Costs Setting scheduled maintenance will also help you lower your costs by avoiding emergency breakdowns and repairs as much as possible. By knowing what fixes need to be done on an equipment, you will have ample time to search for the components required and where to buy them at the most affordable price. You can also afford to ship your purchases at a standard delivery time.
The study, it is based on the analysis of present procedure of project risk management that is followed by Spanish Business Unit of an automotive organisation that mainly manufactures airbags modules and steering wheels. Taking into consideration the PMI standard, different changes are needed in present methodology for the objective of defining and implementing project risk management procedure more efficiently and usefully. Keywords: Project Risk Management; Automotive industry; Risk Procedure; PMI Standard Introduction In the world of business, the presence of risk is involved everywhere, however the nature of risk and its scope has led to accelerate in 21st century. Risk management is the procedure for analysing, responding and identifying
