Equipment availability is a critical metric that equipment owners should measure regularly. It represents the percentage of time the equipment is available to work and serves as a good proxy for reliability. The higher the availability, the more reliable the equipment. Understanding and calculating equipment availability can significantly impact your operational efficiency and bottom line.
What is Equipment Availability?
Definition
Equipment availability is defined as the percentage of time your equipment is available to work. It is a key indicator of equipment reliability and performance.
Importance
High equipment availability means your machinery is dependable. It directly correlates with increased productivity.
Factors Affecting Equipment Availability
Expected Working Hours
The first factor in calculating availability is the number of hours a machine is expected to work in a day. For instance, if a forklift is scheduled to operate for two shifts (16 hours), this figure becomes the baseline for availability calculations.
Downtime Hours
The second factor is the number of hours the equipment is down due to repairs or maintenance. If the forklift is down for 2 hours, these hours are subtracted from the expected working hours.
Calculating Equipment Availability
Formula
The formula to calculate equipment availability is:
Example Calculation
If a forklift is expected to work for 16 hours but was down for 2 hours, its availability would be:
This means the forklift was available to work for 87.5% of the scheduled time.
