Maintenance is an important system in operation. In an era where industries are focusing on 24 hours operation to maximize production, machines are pushed to its absolute limits to cope with this demand. As utilization increases, the rate at which the machine parts get worn out increases thus the frequency of failure increases rapidly. To combat this problem and ensure that machines continue to operate at its optimum, maintenance work is carried out. One of the branches of maintenance technique which is carried out to prevent occurrences of failure before it happen is known as Preventive Maintenance (PM). However, performing PM may not be as easy as it requires great cooperation from the maintenance, production and management departments. This paper is written to study the aspects of effective PM and to analyze the causes of inefficient PM activity in a case study company and its implications.
Another important approach taken is to investigate the causes of machine downtime by performing a root cause analysis. Affinity diagram was formed to highlight several issues with implementation of PM and a further analysis using Tree Diagram enabled to generate possible solutions. The findings of this provides prove that separating the machines into critical and non-critical categories, each having a different priority level is a crucial step towards solving the issue at hand and ensuring the reduction in downtime occurrence in addition to…...

...Module 3 Aircraft Systems and Aircraft Maintenance Learning Objective #10 Determine the requirements for maintenance records, compliance with Airworthiness Directives (AD), preventive maintenance, and alterations. Web Support link: http://www.avweb.com/news/savvyaviator/190596-1.html The Savvy Aviator While browsing the Internet and reading through various FAA websites, I came across a column by a passionate pilot that likes to spread the good, educated, aviation word. I chose column #23: Maintenance Records highlighting the importance of detailed and accurate records, and compliance with FARs. One thing I found refreshing was how casual the author speaks to his audience, yet delivers a wealth of knowledge that is typically only gained through years of experience, both on and off the ground. The author goes into great detail as to what is required from the regulatory sense and what is required per good pilot and mechanic sense. He further breaks it down by addressing complying with airworthiness directives and how to annotate them properly, alterations and the depth at which they need to be captured, and preventive and routine maintenance. I found this article to be very informative and challenged my current maintenance practices, both personally and professionally. The article was simplistic enough that the youngest of aviator or manager would glean the basics, and maybe a few inches deeper of aviation knowledge, and those that have been at this for more than a...

Condition Based Maintenance vs. Phase Based Maintenance

...EXECUTIVE SUMMARY There is an increasing desire for the implementation of condition based maintenance programs to replace the traditional hour based maintenance on Military rotor wing aircraft. There are several advantages and disadvantages to this type of maintenance. The purpose of this paper is to discuss both and the affect that they play in regards to the organizational behavior of a business. There are distinct advantages in regards to cost when we talk about condition based maintenance. Replacing a part only when it is likely to fail saves the cost of replacement at a possible earlier time like in a phase based program, or catching a part that might have failed prior to the required hour inspection or replacement time. But this new technology comes with a cost. A cost, not only monetary, but also within the organizational behavior of a corporation or organization such as the military. When we talk about Managing change and stress, we have to talk about the external forces of change effecting these technological advancements. The technology of condition based maintenance is justified through the savings it generates through the maintenance program but what cost will it have on the people working on these aircraft? Will there be a reduction in jobs? This concern can start trouble, rumors, and decreased production from employees that normally work hard. What effect will it have on the organizational design? Will there be an increase or decrease in managerial roles? Will......

Maintenance Scheduling

...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 must schedule precisely, proceed positively, and persistently pursue weekly targets. Using the results and reports such as those showing schedule compliance, the planner, the supervisor, the maintenance manager, and internal customers can continuously improve the planning, coordination and scheduling function. The schedule is a device for lining up jobs waiting to be performed so that operations are best served while maintenance also makes optimal use of its resources. Four abilities, as listed below, are necessary for maintenance schedules to meet......

Lean Maintenance

...development and maintenance To make application development and maintenance more productive, IT managers are getting lean. Noah B. Kindler, Vasantha Krishnakanthan, and Ranjit Tinaikar Web exclusive, May 2007 Burdened by high costs for application development and maintenance (ADM),1 many businesses have offshored up to half of their application development to low-cost locations, renegotiated rates on outsourced projects, and tightened the governance of new projects. In spite of these efforts, the costs of developing and maintaining applications now account for about half of the average IT budget and continue to rise. Labor costs make up more than 80 percent of application development, so many organizations have already reduced head counts or labor expenses where possible. Now they must begin to focus on improving the productivity of their development and maintenance staffs. In the past companies tried many methodologies, with mixed results (see sidebar, “Software-development productivity: Traditional methods”). Companies that apply the time-tested principles of lean manufacturing, which hunt for and eliminate waste from the production process (Exhibit 1), are seeing a significant impact within a matter of months. Although lean principles were originally developed for manufacturing environments, they are increasingly (and successfully) being applied to service businesses, especially those with many routine processes.2 Application development and maintenance is a......

Computer Maintenance

...Computer Maintenance Shakeyla Pugh A regular maintenance routine will help keep your computer in good condition. A maintenance routine should include cleaning the computer, disk maintenance, and regularly updating virus protection and operating system software. Cleaning An LCD (liquid crystal display) screen should be cleaned using a soft cotton cloth and a solution of water and isopropyl alcohol. The solution should be applied to the cloth first, never sprayed directly on the screen. To clean a keyboard, a can of compressed air can be used to spray in between the keys to push out dust and crumbs. Q-tips, a small flat screwdriver, or sticky notes can also be used to remove dust and crumbs from the keyboard. A can of compressed air should be used to clean the back of the computer tower, especially the cooling fan vents. The exterior of a mouse can be cleaned using a damp soft cloth. If the mouse has a trackball, the trackball should be removed and wiped with a dry cloth. Disk Maintenance Most operating systems have built-in performance and maintenance features that allow the user to free up space on the hard disk and rearrange files on your hard disk to increase efficiency. It is also a good idea to delete any unnecessary files from the hard disk on a regular basis. Updating Software New viruses are continually being created. In order to protect against new viruses, new virus definitions must be downloaded on a regular basis. Most virus protection software has an......

Preventive Maintenance

...thing a business starts with how much. As preventive maintenance relates to a company’s goals. The first thing that the program brings to the table is that it gives a business the ability to us the available maintenance resources for maximum benefit. Problems like this comes in a huge way from reducing the number of failures a company makes which helps keeps low cost minimization in which the big picture is what the company wants. In the coast breakdown, preventive maintenance program is what helps a business save money and is much better than reactive maintenance that is when you fit it when it breaks and results are in a high repair budget, in my opinion. In my long time in a business which maintenance is a very bug part there are four different maintenance program that companies use reactive, preventive, and productive all of these programs result cost in their own way. Each of the different forms effects costs in their own way proactive is when you monitor and correct the failure at the source. Predictive is when you repair based on the conditions of the equipment. Reactive is when it breaks you fix it .Finally, the end, there is preventive maintenance that usually is a planned repair. The breakdown should show that preventive maintenance has the largest impact on the cost, in the big picture. The second main point I will be touching on is down time and how it will greatly effects a business without a preventive maintenance program. Down time for any business can have......

...Chapter 5 Types of Maintenance Programs � 5.1 Introduction What is maintenance and why is it performed? Past and current maintenance practices in both the private and government sectors would imply that maintenance is the actions associated with equipment repair after it is broken. The dictionary defines maintenance as follows: “the work of keeping something in proper condition; upkeep.” This would imply that maintenance should be actions taken to prevent a device or component from failing or to repair normal equipment degradation experienced with the operation of the device to keep it in proper working order. Unfortunately, data obtained in many studies over the past decade indicates that most private and government facilities do not expend the necessary resources to maintain equipment in proper working order. Rather, they wait for equipment failure to occur and then take whatever actions are necessary to repair or replace the equipment. Nothing lasts forever and all equipment has associated with it some predefined life expectancy or operational life. For example, equipment may be designed to operate at full design load for 5,000 hours and may be designed to go through 15,000 start and stop cycles. The need for maintenance is predicated on actual or impending failure – ideally, maintenance is performed to keep equipment and systems running efficiently for at least design life of the component(s). As such, the practical operation of a component is time-based function.......

Illinois Maintenance

...Illinois Maintenance Guidelines and Formula Valerie Hiller Kaplan University CM107 Professor Snchieder June, 23, 2015 MEMO TO: Letisha Luecking Orlet P.C., Tom Speedie Attorney at Law, and Dennis Hatch Attorney at Law FROM: Valerie Hiller, P.C. SUBJECT: New maintenance guidelines and formula DATE: December 16. 2015 According ISBA (Mathewson, 2014), the new law, P.A. 98-0961, was crafted by ISBA Family Law Section Council, creates a formula for calculating maintenance based on the gross income of the parties and the length of marriage. Before this law was established, judges relied on a list of factors that appear in sections 504 and 505 of the Illinois Marriage and Dissolution of Marriage Act. Spousal maintenance is determined for divorcing couples whose combined gross income is less than $250,000.  With the new formula, a maintenance award should equal 30 percent of the payor’s gross income minus 20 percent of the payee’s income, not to exceed 40 percent of the couples combined income when added to the payee’s gross. There are two formulas in this guideline. The maintenance that the payee has to pay and the length of payment to the payor, with this formula, it will establish the durations of the maintenance award. The payee will have to continue paying award for 20 percent of the span of marriage. Or it may be permanent or last the whole length of marriage for a couple that has been married 20 years or......

...has undergone dramatic structural changes over the past few decades, with the rise of the biotechnology sector, substantial growth in demand driven by demographics and substitution away from other therapeutic modalities such as surgery, and increased competition from globally active generic manufacturers. The pharmaceutical industry is under mounting scrutiny because of rapidly increasing expenditures for drugs in the United States. Drug expenditures are now the fastest-growing component of health care costs, increasing at the rate of about 15 percent per year. They account for about eight percent of health care spending, and at their current rate of increase, they will soon surpass spending for physicians' services and, for many health maintenance organizations (HMOs), the costs of hospitalization. Aruvian's R'search brings you a complete analysis of the Pharmaceutical Industry in the United States. The report covers a brief profile of the global pharmaceutical industry, the TRIPS agreement and the effect of the agreement on the US pharmaceutical industry, offshoring in the pharmaceutical industry, economic trends in the industry, competition in the industry, and key trends in the pharmaceutical supply chain in the United States.
