Enhanced reliability and efficiency will in turn contribute to improved economic and safety performance of the plant equipment. 245.2. Cost Benefits Cost reduction benefits are not the primary goal of the RCM process however, EdF estimate that the application of RCM to their maintenance programmes will produce a maintenance cost reduction of 7 Million Euros over a period of 2004-2007 when applied to a large standardised fleet. Conversely, the experience in the Czech Republic where RCM was applied to a small number of systems at the Dukovany NPP the experience proved to be maintenance cost neutral. The experience of cost savings through the application of RCM in France, Spain, UK and Czech Republic are detailed in the Attachments to this TECDOC. Many are quoted in the form of task and man-hour reductions. 5.3. Contribution to Long Term Operation RCM is a systematic approach to the identification and execution of maintenance activities designed to support plant performance. The associated condition monitoring programmes and analytical techniques ensure excellent knowledge of plant condition and can provide early warning of plant aging and obsolescence issues which are vital for asset management. The data collected and the maintenance practices developed are conducive to long term asset management strategies. 5.4. Soft 5.4.1. Operations and Maintenance interaction...

The goal of the TPM program is to markedly increase production while, at the same time, increasing employee morale and job satisfaction. The TPM program closely resembles the popular Total Quality Management (TQM) program. Many of the same tools such as employee empowerment, benchmarking, documentation, etc. are used to implement and optimize TPM. This paper will define TPM in some detail, evaluate its strengths and weaknesses as a maintenance philosophy, and discuss implementation procedures. Examples of successfully implemented programs will be presented. I. What is Total Productive Maintenance? Total Productive Maintenance (TPM) is a maintenance program concept. Philosophically, TPM resembles Total Quality Management (TQM) in several aspects, such as (1)total commitment to the program by upper level management is required, (2) employees must be empowered to initiate corrective action, and (3) a long range outlook must be accepted as TPM may take a year or more to implement and is an on-going...

...MARKET SCOPE Asset performance management Addressing the root cause A properly and adequately designed asset performance management framework can bring a cohesive approach to manage assets, monitor equipment health, and ensure the compliance of critical operational & business processes. Such a framework has to leverage the established asset management capabilities provided by the best-in-class systems. Courtesy: PCM Ltd n the 1980s, the world was awakened by two major disasters that signified the vitality of engineering assets and the importance to manage their performance. The first event was a lethal methyl isocyanate (MIC) leak in Bhopal on December 2, 1984, and the second the catastrophic Chernobyl nuclear disaster on April 26, 1986. Over 20,000 were killed, and half a million victims maimed, disabled or otherwise affected in the Bhopal gas tragedy. Criminal cases were filed against the then corporate Chairman. In the Chernobyl reactor, the accident happened because of a combination of basic engineering deficiencies in the reactor and faulty actions of the operators (as per UN Chernobyl Forum report, the safety systems had been switched off, and the reactor was being operated under improper, unstable conditions, a situation which allowed an uncontrollable power surge to occur). More than 20 years have passed since the tragedy occurred, and it is difficult to tell precisely the number of deaths – past and future – attributable to the Chernobyl accident. Since the...

...Recommend and Implement a New Maintenance Ticketing Process Comcast South Florida has recently launched its new Customer Guarantee program that guarantees the work and services performed for 30 days or the consumer is able to receive several different packages as compensation. Recently the organization has changed its ticketing process when referring jobs to the Maintenance / Engineering Department and has asked my local leadership team to review and revamp the new process. This proposal provides a brief overview of the current process including its intricacies and outlines how we will perform our research and testing in preparation for our full report. Problem The newly revised Maintenance / Engineering ticketing system (also known as the - refer to maintenance) was intended to streamline the process and reduce downtime. Unfortunately, this revised ticketing process resides within its own system (TTS and Watchtower) and does not communicate with the current billing system (CSG), work order system or the call center. This has caused unnecessary additional down time for customers if their issues were not resolved the 1st time, financial loss from the company’s perspective and an inconvenienced customer. We need to identify a methodology that will allow the new ticketing system to communicate to the traditional billing system and all cross-functional areas. Justification/Feasibility With the new addition of Watchtower and TTS maintaining and issuing maintenance ticket numbers, the communication...

...The ABC’s of Failure – Getting Rid of the Noise in Your System For the past 40 years, I have observed many companies, including DuPont (where I spent 27 years) pursuing planned maintenance with the standard tools of planned maintenance: inspections, planning, scheduling, materials procurement, CMMS systems, etc. with the same results. They succeed for a while and get their percent planned and scheduled maintenance up to the 80+ only to see that drop back later to 60 I am amazed how many of the companies we work with have had this experience. This pattern of behavior has led us to conclude that the reason for this experience is that only 60% of the normal work of maintenance is inherently plannable. The rest of the work is created by random acts of what we are now calling care-lessness. The sites where we see people break this pattern and achieve 92% to 96% planned maintenance for the long term without regressing, are the ones who eliminate the inherently unplannable work. Of course, this cannot be done by maintenance alone. Everyone who does work at a site contributes to the defects that create the unplannable work, and therefore everyone must participate in eliminating the defects that create the 40% of the work that is unplannable. In the diagram below we attempt to more clearly articulate the true significance of Defect Elimination by outlining the ABC’s of failure. Fundamentally, failures happen because things that exist are not perfect. To reduce failures we must eliminate...

.... Chapter Failure prevention and recovery 19 Eurotunnel response team during one of their regular patrols in the tunnel Source: Eurotunnel Introduction One obvious way of improving operations performance is by preventing failure. Failure is rarely unimportant, but in some operations it is vital that processes do not fail. Failure in aircraft in flight, for example, or electricity supplies to hospitals, or car seat belts, or the emergency services can be literally fatal. For these operations dependability is not just desirable, it is essential. Even in less critical situations, having dependable processes can give a competitive advantage. But no process is perfect and failures will occur. So it is important that we learn from all failures and have plans in place which help them recover and minimize their effects. Figure 19.1 shows how this chapter fits into the operation’s improvement activities. Operations strategy Failure prevention and recovery Operations process improvement makes processes better Design Operations management Improvement Total quality management organizes process improvement Planning and control Failure prevention and recovery stops processes becoming worse Topic covered in this chapter Figure 19.1 This chapter covers failure prevention and recovery . 618 Part Four Improvement Key questions I I I I I ???

...completed much faster by technicians that perform it regularly and have all of the special equipment necessary. Taking everything into consideration I recommend that we outsource the inspection. Should Pacific Jet outsource the 72 month inspection? This is the first 72 month inspection that our 135 charter company (Pacific Jet) has coming due. Since we are a small operation with only 3 aircraft and 4 maintenance technicians performing a 72 month inspection in-house will be a huge undertaking. The main items to consider are costs, aircraft downtime, and quality control issues. We have to decide if we want to perform this inspection in-house our outsource it. The airlines have been outsourcing maintenance for decades and have accelerated this outsourcing rapidly since 2001. In 2005, some airlines outsourced as much as 62 percent of their maintenance and that number continues to grow. While they have increased their outsourcing of maintenance their accident rates have declined, statistically proving that outsourced maintenance is safe (Armstrong, 2007). There are many companies that could perform this inspection for us if we decide to outsource...

...performance. Resources include manpower, materials, tools and special equipment. Access refers to when the equipment will be prepared and accessible so that it can be worked on in safe (locked out/tagged out) condition, with necessary precautions taken, permits obtained, and any specialized documentation, drawings, or information in hand. Proper time relates to job start, duration of execution, and completion within the time frame agreed upon with the internal customer during the weekly coordination meeting. The Weekly Expectation Scheduling is the locus from which all maintenance activity is executed. Scheduling should be viewed as the “point” function and “marketing arm” of the system because it yields the earliest tangible results (often within weeks of start up). All individuals and groups perform better and accomplish more with clearly established, communicated and published expectations. When the maintenance function is managed without a weekly schedule, there are no specific expectations as to what is to be accomplished with the resources for which payroll checks will be drawn. Instead, whatever reactive demands are made is what will be done. The fundamental requirement target (the schedule) against which to control, followed by action (execution of the schedule) to achieve the target. The results, measured against the original intention (called schedule compliance), provide feedback for correcting deviations (improving future schedule compliance). Managers...

...our spirit all aided us to surmount difficulties during doing the research and show our ability confidently as well. We are also indebted to HUCFL Second - year English students for their cooperation to complete our questionnaires and their active contributions to suggest feasible solutions for our research topic. Last but not least, we can’t help mentioning the remarkable efforts of our group members. They conducted the research to the best of their ability and worked very hard to perfect the research as well as possible. Their merits are thankworthy. ABSTRACT Our research was carried out to investigate the attitude of HUCFL Second- year English students toward the school facility protection and some solutions for school facility maintenance. Due to the important of school facilities in the cause of HUCFL’s education- training and its status quo, we carried out the small- scale research to examine main causes of HUCFL’s facility damage. We delivered 20 questionnaires randomly to the Second – year English students and we thereafter analyzed the data collected from those questionnaires. Based on the research findings, we had the clear understanding about the concerned reality of HUCFL’s school facilities and the close relationship between the lack of students’ awareness and the degraded quality of the facilities. What is more, we realized that the students’ responsibility for protecting the school facilities is the main...
