Maintenance management, Figure

Let s follow some of the physical plant inadequacies up the safety control structure at Citichem. Three examples of STAMP-based analyses of the inadequate control at Citichem are shown in figure 11.3 a maintenance worker, the maintenance manager, and the operations manager. 

Figure 6.1 shows a supply-chain view of the aircraft service activities. Data are tracked in two separate databases Aviation Computerized Maintenance System (ACMS) and Aviation Maintenance Management System (AMMIS). The ACMS database stores individual part-level serial number tracking and history of repairs and planned maintenance. The AMMIS database tracks flow of the broken part as it is repaired. In the original system, these two databases did not communicate ([27]).

The most important KPl within maintenance management is Overall Equipment Effectiveness (OEE). OLE is a KPl for visualizing losses within availability, performance and quality for production machines. By visualizing the size of these losses, OEE reveals the improvement potential. The figure is calculated by multiplying availability rate, performance rate and quality rate (Koch 2007). 

A preventive maintenance program can be developed for any industrial function that has a maintenance component. The same principles used in the truck operator example in this chapter can be used for other mobile equipment, machinery, or process maintenance (see Figure A.3). It matters little the type of maintenance. It is more important that the workers, operators, supervisors, and management realize that the care taken in prevention will pay dividends in cost savings, accident costs, less equipment damage, and better overall working conditions and employee attitudes. Care of your physical assets (physical plant, vehicles, machinery, etc.) is critical to the bottom line. The bonus is that you will reduce one of the factors that can contribute to your occupational injury rate. 

Of iqtecial impmtance is the notion of composition of operations. An operation in the composite class may be implemented in terms of operations of its component classes. For example, in figure 12 the operation "Maintenance.Repair is implemented in terms of dix operations of its component classes. Five from the planner agent ("Estimate", "Resource ldentify", "Schedule", "Prt )ose" and "Refo ") and one from the maintenance management system object in figure 8 (Daily Scheduled Work). 

In addition to these formal studies of human error in the CPI, almost all the major accident investigations in recent years, for example, Texas City, Piper Alpha, Phillips 66, Feyzin, Mexico City, have shown human error as a significant causal factors in design, operations, maintenance or the management of the process. Figures 4.4-1 and 4.4-2 show the effects of human error on nuclear plant operation. 

We have developed an approach to managing patients with bipolar disorder during the maintenance phase ( Fig.10-2). Another approach to the management of bipolar, depressed episodes is contained in Figure 10-4. 

As part of the conceptualization period, senior managers are presented with, and estimate the total effort to be expended (including maintenance for the project). The relative costs of each development stage are depicted in Figure 8-2.2 Note Maintenance of existing software can account for over 70% of all effort expended by a software organization and this cost will be passed on to the customer. 

Maintenance and repair costs (M R) are a deductible corporate expense against taxable income. Using appropriate tax terminology on all M R work orders will save your company money. The costs associated with Capital Expenditures (capital) and Service to Operations are not deductible. Key words used in computerized materials management databases should help clarify these categories and should be used for effective cost savings. See Figure 2-15.
