To minimize downtimes and maintenance costs, the technical systems in a company are inspected and maintained regularly. You want to understand the plans that can help you manage this maintenance. For this reason, you need to understand single cycle plans (time-based) and strategy plans (time-based).
Single Cycle Maintenance Plan
Single cycle plans are used to manage the maintenance of machines and operational systems, which are always inspected and/or maintained in the same way at fixed intervals.
In this plan, the same activity is executed at regular intervals.
Some examples of a single cycle plans are as follows:
- Annual inspection of fire extinguishers
- Technical inspection every two years
- Inspection of boilers every six years, as per pressure vessel regulations
The following video provides an information about the maintenance plan, i.e., scheduling data and maintenance items.
A maintenance plan can have one or more maintenance items. For example, in pump maintenance, one maintenance item refers to the pump transmission with the corresponding task list. Another maintenance item refers to the pump motor with the corresponding task list.
A task list is assigned to a maintenance item. The system calculates the times when the maintenance plan is scheduled.
In the case of a single cycle plan, the complete task list is always due.
Strategy Maintenance Plan
The following video provides an information about the strategy plan.
Task Lists in Strategy Plans
Task lists can be created for use in preventive maintenance. To prepare task lists for use in strategy plans, the following steps are required:
- Assign a maintenance strategy in the task list header.
- Assign packages to different operations in the task list.
This defines the frequency with which the operations have to be executed.
You assign a maintenance strategy to a strategy-based maintenance plan.
Only a task list that has the same maintenance strategy as the maintenance plan can be assigned to a strategy-based maintenance plan.
