Computerized maintenance management system is also known as computerized maintenance
management information system.
A CMMS software package maintains a computer database of information about an organization’s
maintenance operations, i.e.
CMMIS – computerized maintenance management information system.
This information is intended to help maintenance workers do their jobs more effectively and
to help management make informed decisions.
CMMS data may also be used to verify regulatory compliance.
CMMS packages may be used by any organization that must perform maintenance on equipment,
assets and property.
Some CMMS products focus on particular industry sectors.
Other products aim to be more general.
CMMS packages can produce status reports and documents giving details or summaries of maintenance
activities.
The more sophisticated the package, the more analysis facilities are available.
Many CMMS packages can be either web-based, meaning they are hosted by the company selling
the product on an outside server, or LAN based, meaning that the company buying the software
hosts the product on their own server.
CMMS packages are closely related to computer-aided facility management packages.
For the purposes of many organizations, the two are interchangeable.
Work orders Scheduling jobs, assigning personnel, reserving
materials, recording costs, and tracking relevant information such as the cause of the problem,
downtime involved, and recommendations for future action.
Typically, the CMMS schedules preventive maintenance automatically based on maintenance plans and/or
meter readings.
Different software packages use different techniques for reporting when a job should
be performed.
Inspection Details condition of assets.
Preventive maintenance Keeping track of preventive maintenance jobs,
including step-by-step instructions or check-lists, lists of materials required, and other pertinent
details.
Machine breakdown Incidence of machine breakdown, details of
repairs completed and repairs "to do".
Preventive maintenance tasks are often undertaken during breakdown repair and so preventive
maintenance tasks need to be rescheduled.
Asset management Recording data about equipment and property
including maintenance activities, specifications, purchase date, expected lifetime, warranty
information, service contracts, service history, spare parts and anything else that might be
of help to management or maintenance workers.
The CMMS may also generate metrics such as the Facility Condition Index to measure effectiveness
of asset management.
Safety Management of permits and other documentation
required for the processing of safety requirements.
These safety requirements can include Lockout-Tagout, confined space, foreign material exclusion,
electrical safety, and others.
System integration CMMS packages often link to enterprise software
and process control systems: Scheduling
Asset management Fixed assets Details the machines being maintained
and their associated tooling Parts inventory / Parts locations / purchasing
Costing SCADA Scheduled maintenance based on number
of units of output or condition of machines OEE Systems – to reduce maintenance response
