Maintenance Planning and Scheduling

Maintenance Planning and Scheduling

• Work planning involves assigning work orders to time and planning resources.
• Work scheduling involves arranging the sequence of work orders, considering factors such as priority, availability of artisans/technicians, and availability of material and equipment.

Priority System

• A priority system is established to ensure that the most needed work orders are scheduled first.
• Examples of priorities include:
  • 0: emergency or safety work
  • 1: work to start within 24 hours
  • 2: work to start within 1 week
  • 3: work to start within 1 month
  • 4: overhaul/other

Backlog Management

• Backlog refers to all work available to be done, which has been approved and prepared.
• Backlog must be used as a tool to make decisions, informing management about future needs for maintenance (e.g., contracting, more/less personnel).
• Effective backlog management is necessary to prevent it from growing to an unmanageable size.

Calculating Backlog

• Backlog can be calculated using the formula: Work on hand – (Max. available hrs X 100) / Max. available hrs.
• Max. available hrs = workforce available hrs – (workforce x 15%).

Reducing Backlog

• Options to reduce backlog include:
  • Overtime
  • Contract workers
  • Appointing additional staff

Work Preparation

• Work preparation is important for:
  • Facilitating estimation
  • Ensuring jobs are done in the most efficient manner
  • Contributing to training by indicating the methodology of the job
  • Providing a basis for future job preparation when the job needs to be done again
