Some researchers argue that the cost of spares is always an area where cost reduction can be of significant. With the help of suppliers and equipment vendors, purchasing department can place orders in the form of contracts or Service level agreement (SLA) that guarantee delivery lead times for the designated inventory items. It makes business sense to shift the risk concerning the cost of maintaining the inventory to the suppliers. Reliability is the probability that the plant will perform its intended function satisfactory under specified 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 …show more content…
Yan et al (2008) & Ebeling (1997), pointed out the purpose of maintenance is to extend equipment life and minimise the frequency of service interruption. Ebeling (1997) concluded that availability is the important index of the all indices for power availability. Several maintenance types or tactics have been suggested by many authors for example (Mowbray, 1991 and Kelly, 1997). There are mainly two types of maintenance practices and these are breakdown and preventive maintenance. Breakdown maintenance requires replacement of damaged part of the equipment during unscheduled maintenance while preventive maintenance requires replacement of the components at pre-determined intervals. Condition based maintenance is used to monitor the condition of the equipment using condition monitoring technique.
There is a general belief that corrective maintenance is less economical than preventive maintenance, and all failures can then be prevented. This approach to preventive maintenance firstly wastes a lot of resources in doing unnecessary tasks which will not improve equipment or system availability and secondly it is potentially risk (Tsang,1995).Principal argument in favour of detailed and integrated asset information system that is accurate and unchallenged information is available to anyone with skills to analyse and interpret it for the benefit of a company (Sherwin, 2000).Predictive scheduling relies more on
Supportability is a design characteristic that requires an early focus during maintenance planning to identify support
The Values and Motives Questionnaire, also known as the Values and Motives Inventory, is designed to examine a person’s motivation in relation to his values and activities. In order to ensure a comprehensive understanding of values, the VMQ assess three distinct areas, including: interpersonal, intrinsic, and extrinsic. Interpersonal values, according to the VMQ refer to one’s relationships with others. Intrinsic values contain one’s personal beliefs and attitudes. Finally, extrinsic values are one’s motivating factors at the workplace. Each of these three areas contain twelve topics

The purpose of Army maintenance is to preserve the required performance capabilities of Army materiel or to return those assets to their baseline performance capabilities. Maintenance is an enabling process to meeting Army Force Generation (ARFORGEN) requirements. ARFORGEN is the process used to generate and regenerate combat power and preserve the capital investment of combat systems and equipment to enable training and mission accomplishment (Department of the Army, 2013). The Army’s doctrinal definition can be confusing to some and it does not make mention of efficiency, reducing non-value adding activities and the overall equipment effectiveness. This definition allow for commanders at all levels the flexibility to focus on other tasks, tasks not related to maintenance.
Every morning and every after maintenance action we ATAF which means all tools accounted for. During any job an ataf should be had at all times, but how many times are you supposed to ataf your tools? An ataf is performed before the cdi checks your box to be checked out, it is then checked by the cdi so they can check the box out to you to use, before you go out and do your job on the flight line in the hangar etc. when you get out to your job another ataf should be performed and you yet again make sure you have all of your tools, any work stoppage for example,
Urbacon of Toronto Canada is requesting information regarding computerized maintenance management system (CMMS) for the purpose of managing Urbacon’s Data Centre facilities assets. The intent is to obtain information leading to the selection of a Computer Maintenance Management System product or service. Urbacon invites all interested parties to submit a written response to this Request for Information (RFI).
The maintenance contract may also include 24/7 call-out service at a set price in the event of an emergency, so you won't have to a) wait longer
Preventive Maintenance Checks and Services (PMCS) means systematic caring, inspecting, and servicing of military equipment to keep it in good condition and to prevent breakdowns. The operator of the vehicle mission is to be sure to perform PMCS each time he/she operate the vehicle. Always do the PMCS in the same order, so it gets to be a habit. Once you've had some practice, you will quickly spot anything wrong.
This is something that must be addressed in supply chain management because if one area of the company is operating below capacity the other sectors will not be able to make up this lack of production. Another main component of supply chain management is how to handle damaged goods. It is a waste of money to send out defective products because it costs the organization large amounts of money to recall the damaged materials back to the factory and replace them, slowing production efficiency. There must be quality controls and regulations that enable Ford to minimize inventory defects and returns. The Ford Motor Company must have damage control operations to continue manufacturing the same amount of automobiles so that they do not lose any necessary inventory. There must also be procedures in place that deal with delivery systems and the delays and unsuitable materials that could easily occur. This paper will fully break down the previous issues associated with the Ford Motor Company 's supply chain management and operations. SUPPLY CHAIN MANAGEMENT OF FORD Synopsis of Supply Chain Management as it Applies to Ford The definition of supply chain management (SCM) involves taking a systems approach to the entire supply chain with the overall goal of reducing the level of risk and uncertainty throughout the supply chain. This will ultimately permit lower
Reliability is generally a measure of how the probability will work to protect the system as intended. Reliability is a combination of the two metrics, dependability, and security. Dependability is the expectation that the protection will work when you need it. Security is the expectation that protection will not work when it is not needed. These requirements are usually in conflict due to the difference obscure between the events of the system are acceptable and intolerable. This uncertainty means that the best source of knowledge for the design of protection systems usually prior experience, although simulation and testing can provide some insight.

The quality of the analysis was checked by “pstest” to understand and manage the mean bias to not more than 5 and balancing test before and after matching was conducted. Based on selected propensity algorithms treated and non-treated household were insignificance by all covariates after matching (Appendix 2 & 12).
Maintenance decision is typically made based on tool condition change/degradation. However, the change does not necessarily lead to poor quality of the product. Change-based maintenance decision making may lead to over-maintenance. This report focuses on develop prognosis for maintenance scheduling model. We first study current maintenance situation in Samsung semiconductor system, follow by that, generating data to illustrate the decision making process according to a potential optimization model that accommodates with productivity and preventive maintenance task scheduling in the report.
In order to compile a comprehensive database of wind turbine component reliabilities that could be used for wind projects O&M cost estimates and suitability evaluation of component, UL would have to start requesting reports of component failures for all the projects UL is working at.
In order to sustain high plant 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 because production per unit (Kwhr) of electricity would reduce. Previous studies indicated that maintenance and its relationship with equipment availability revealed that preventive maintenance for
