Above is a graphical depiction of a MEL. Note, data starts with the Class and Subclass of every asset in a facility. Following the blue highlighted area, this listing will start with class=bearing, then subclass=ball, then attribute=type and then value=precision ground. The minimum would be four levels within the MEL. There are many variations that would make up the MEL, the graphic is only a single example of one such asset. Also this MEL is made up of all of the individual components of an asset and will serve as the base for the Bill of Materials.
Once an accurate MEL is built, the remainder of the technicians data work is in building the route list. Above is an example of a tree leading to the route based location of individual components on an inspection route. Note: Bldg 1, lower level, MCC and the equipment name is similar in nature to the MEL described above. This tree can and should be linked to the MEL which will then feed directly into the EAM/CMMS and therefore, feed directly into the Planning and Scheduling areas of a facility. Below is another example of how this tree list might appear in a graphic user interface (GUI) on a route based data collection device.
Enterprise Asset Management (EAM)
Definition: The whole life optimal management of the physical assets of an organization to maximize value. It covers such things as the design, construction, commissioning, operations, maintenance and decommissioning/replacement of plant, equipment and facilities. "Enterprise" refers to the management of the assets across departments, locations, facilities and, in some cases, business units. By managing assets across facilities, organizations can improve their utilization and performance, reduce capital costs, reduce asset-related operating costs, extend asset life and they may subsequently improve ROA (return on assets).
Asset intensive industries face the harsh realities of operating in highly competitive markets and deal with high value facilities and equipment where each failure is disruptive and costly. At the same time, they must also adhere to stringent occupational safety, health and environmental regulations. Maintaining optimal availability, Reliability and operational safety of plant, equipment, and other assets, is therefore, essential for an organization's competitiveness.
The functions of asset management are taking a fundamental turn where organizations are moving from historical reactive (run-to-failure) models and beginning to embrace whole life planning, life cycle costing, planned and proactive maintenance and other industry best practices. However, some companies still consider physical asset management as another term referring to maintenance management. Once these organizations realize the enterprise-wide impact and interdependencies with operations, design, asset performance, personnel productivity and lifecycle costs, will this shift in focus progression from maintenance management to Enterprise Asset Management.
EAM/CMMS, forms the enterprise system and corporate philosophical base by which maintenance Planning and Scheduling, parts order and replacement etc… may be managed and optimized, it is the life and blood of a proactive maintenance driven organization. It also provides a centralized source for standardized information.
