Create a Calendar-Based Maintenance Plan
Learn to create a calendar-based maintenance plan in ManWinWin Desktop using a fixed time interval and an existing work description. Configure a schedule that repeats without a maintenance cycle.
Establishing a robust calendar-based maintenance plan is crucial for proactive asset management, ensuring timely interventions and minimizing unexpected downtime. This approach leverages fixed time intervals to schedule preventive tasks, providing predictability and structure to your maintenance operations.
Where it's available and step by step
Step by step in ManWinWin Desktop
- 1
Select the equipment, right-click and open Maintenance Plans.
- 2
Start creating a maintenance schedule for a plan without a maintenance cycle.
- 3
Select the existing “Pump Inspection” work description for the schedule.
- 4
Set the scheduling basis to Calendar, without a running-record basis.
- 5
Enter the agreed time interval, for example 30 days, checking that the value and time unit match the maintenance requirement.
- 6
Specify the initial scheduled date for the recurring inspection.
- 7
Set Next MSch to this same maintenance schedule so that it repeats itself.
- 8
Review the work description, calendar interval and scheduled date, then click OK to save.
Theory and technical background
The Importance of Calendar-Based Maintenance
Calendar-based maintenance, a core component of preventive maintenance, involves scheduling tasks at predetermined time intervals, regardless of asset usage. This method is ideal for tasks like routine inspections, lubrication, or statutory checks that need to occur periodically to prevent degradation or ensure compliance. It provides a structured backbone for maintenance, improving planning and resource allocation. While not responsive to actual asset condition or usage, it serves as a foundational layer, preventing common failures and ensuring a baseline level of asset care.
Integrating with Preventive Maintenance Strategy
Calendar-based scheduling is a fundamental strategy within a comprehensive preventive maintenance program. It often complements condition-based or usage-based maintenance by covering tasks that don't depend on specific operational parameters. Effective integration ensures that all critical maintenance needs are met, reducing the likelihood of failures. By standardizing task intervals, it supports consistent maintenance quality and aids in forecasting future workload and spare parts requirements, contributing to better budget control and operational efficiency.
KPIs Supported by Effective Scheduling
Well-implemented calendar-based maintenance directly contributes to several key performance indicators (KPIs). By ensuring timely preventive actions, it helps improve asset Availability, reducing unscheduled downtime. It can positively impact Mean Time Between Failures (MTBF) by preventing common wear-and-tear issues. While not directly measuring OEE, reliable scheduling underpins stable production, which is vital for OEE. Tracking compliance with scheduled tasks, known as Preventive Maintenance Compliance (PMC), becomes a crucial KPI to monitor the effectiveness of your calendar-based plans.
Best practices
- Regularly review and adjust calendar intervals based on asset performance and manufacturer recommendations.
- Ensure work descriptions are clear and concise, detailing all steps required for the inspection or task.
- Allocate sufficient resources (personnel, tools, parts) in advance for upcoming scheduled tasks.
- Utilize your CMMS's reporting features to track adherence to the calendar schedule and identify bottlenecks.
Frequently asked questions
Why use calendar-based maintenance instead of running-record?
Calendar-based maintenance is best for tasks needing fixed time intervals, like daily checks or annual certifications, regardless of asset usage. Running-record bases maintenance on actual asset usage or condition, suitable for tasks triggered by operational metrics.
How often should I review my calendar-based plans?
Review your calendar-based plans annually or whenever there's a significant change in asset usage, operating environment, or regulatory requirements. This ensures intervals remain optimal and relevant.
Can calendar-based plans adapt to changes in operations?
Yes, calendar-based plans are flexible within a CMMS. You can easily adjust frequencies, initial dates, or associated work descriptions as operational needs evolve, maintaining plan relevance.
