...bound to compensate the refineries for such losses. The culprits involved frequently tanker drivers, depot operators and transporters. One of the major customer of PHSB, Oilene Refineries (Oilene) complaint about the quality of the CPO delivered by PHSB and its later impact on Oilene’s failure to fulfil their customer orders. This is because of the practice of siphoning CPO and adulterating the consignment with water, used oil or sludge was so uncontrolled that a number of PHSB’s customers have threatened to change their custom to other more reliable transport companies. Besides that, profits for the first quarter of 2009 had drastically decrease compared to the same period on the previous year due to the high compensation expenses and maintenance cost. These matters worried Datuk Najeed whom then insisted En. Rossly inspect the matters and report to him within one week with possible solutions. En.

...Dwayne Bell General Manager the Inn Restaurant 1 Country Inn Road Upscale, Az.85251 August 10, 2010 Mr. R. Shaky Owner the Inn Restaurant 1 Country Inn Road Upscale, Az.85251 Dear Mr. Shaky: It has been a month since I was hired as GM of the Inn Restaurant. I am settling in well and look forward to a long prosperous relationship. I would like to take this opportunity to discuss with you some items of concern regarding the condition of the building. During this site inspection the following things caught my attention. * Old trees have grown so that their branches could become entangled in the power lines connected to the restaurant * Many of the windows have gaps possibly from the building settling * Water is not properly drained from the building. * Spider web pattern of cracks forming on the foundation. * The roof has tar paper that is pulled up in one section along with bird nests and tree branches. * There are also charred markings around the exhaust vent of the hood system. These are all potentially hazardous situations for our guest and staff. If we do not take action to fix these issues it will not only affect our bottom line but our ability to stay in business at all in this facility. The trees pose several problems. With the branches being so close to the power lines could potentially cause a fire if wind gust cause them to snap and clog up or wear down the gutter system. The roots could be clogging drains underground which could...

...Preventive maintenance (PM) has the following meanings: 1. The care and servicing by personnel for the purpose of maintaining equipment and facilities in satisfactory operating condition by providing for systematic inspection,detection, and correction of incipient failures either before they occur or before they develop into major defects. 2. Maintenance, including tests, measurements, adjustments, and parts replacement, performed specifically to prevent faults from occurring. The primary goal of maintenance is to avoid or mitigate the consequences of failure of equipment. This may be by preventing the failure before it actually occurs which Planned Maintenance and Condition Based Maintenance help to achieve. It is designed to preserve and restore equipment reliability by replacing worn components before they actually fail. Preventive maintenance activities include partial or complete overhauls at specified periods, oil changes, lubrication, minor adjustments, and so on. In addition, workers can record equipment deterioration so they know to replace or repair worn parts before they cause system failure. The ideal preventive maintenance program would prevent all equipment failure before it occurs There is a controversy of sorts regarding the propriety of the usage “preventative.” Three kinds of maintenance: Preventive Corrective Block What is Preventative Maintenance? Preventative maintenance (or Preventive Maintenance ) is maintenance that is regularly performed...

...Proceedings of the 2012 International Conference on Industrial Engineering and Operations Management Istanbul, Turkey, July 3 – 6, 2012 Effective Preventive Maintenance Scheduling: A Case Study Hasnida Ab-Samat, Livendran Nair Jeikumar, Ernnie Illyani Basri, Nurul Aida Harun and Shahrul Kamaruddin School of Mechanical Engineering Universiti Sains Malaysia Engineering Campus, 14300 Nibong Tebal, Penang, Malaysia Abstract 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...

...different and requires scaling steps through each phase of the design. The procurement of goods, manufacturing, material handling, warehousing, storage, distribution, transportation, and maintenance are just a few of the most common elements a firm must coordinate in the design of a system. Before the end result of a design is executing its intended purpose, the measure of logistics and system support are exercised throughout the design phase. The reliability, maintainability, and availability outline one of the most important factors in the success of a system design and are considered vital requirements before moving forward with supportability, design and production. Reliability, Maintainability, and Availability The success of a system is dependent on many things but none more important than its availability. The availability of a system is reliant on its reliability and maintenance requirements. As Blanchard (2004) explains, “The ultimate objective is to design and develop a system that will perform as intended, is available when required, and is cost-effective during its period of utilization” (p. 46). In order to meet this objective, availability of the system must be continually optimized to reach maxim production. Reliability Reliability determines maintenance requirements and affects availability of a system. As Blanchard (2004) defines, “Reliability can be defined simply as the probability that a system (or product) will perform in a satisfactory...
