Maintenance management can be considered as the direction and organization of resources to control the availability of equipment. The tasks associated with maintenance can be divided into three main areas; work management, plant condition control and cost control.
Work Management
Work management is concerned with the logistics of organizing maintenance and has the following objectives:
* To identify, control and co-ordinate the resources (labor, spare parts, materials and tools) * To ensure that job priorities are correctly allocated * To locate plant failures or potential failures and provide an appropriate response
Plant Condition Control
Close monitoring and control of the overall plant condition is necessary to achieve a high level of plant availability. Its long-term objectives are:
* To highlight maintenance engineering problems by monitoring plant performance, diagnosing causes and providing effective solutions * To adapt maintenance policy as production requirements change. This should not be restricted to changes in preventive maintenance but should encompass re-design and the application of condition monitoring techniques where appropriate.
Cost Control
The third activity, cost control, is normally operated as part of a company’s budgetary and expenditure control system, primarily for job costing. The objective will be to make use of the available management tools to achieve the improvements in maintenance effectiveness and efficiency.
Computerized Maintenance Management System (CMMS)
A computerized maintenance management system will contain a number of integrated programs or modules to improve the efficiency and effectiveness of the maintenance engineering function. In this sense the system is like a set of tools, albeit highly complex and difficult to produce. But with the correct design the system should be easy to use and provide the engineer with all of the information that is required to
