Figure 6
The horizontal axis is labeled “month 0 to 12” and displays months from month 0 through December. The vertical axis is labeled “number of pending P M tasks” and ranges from 0 to 70 in increments of 10 units. Data points labeled “task 1” through “task 20” are plotted, as indicated in the legend. Month 0 shows a tight cluster of very high values between approximately 30 and 65 tasks across all twenty categories. From January onward, the plotted points are widely dispersed but consistently lower, generally ranging between 0 and 30 tasks depending on the category. Across the year, values fluctuate slightly month to month but remain far below the initial month-zero levels, indicating that pending tasks decrease sharply after the starting point and then stabilize with modest variation across categories. Note: All numerical values are approximated.Maintenance support planning to visualise the number of planned preventive maintenance tasks
