Is My Method for Calculating Equipment Utilization and Availability Correct?

I am facing a problem and request your assistance in finding a solution.

Calculating Utilization and Availability of Equipment

Let's consider the following scenario:

- Shift hours for a month = 300
- Work hours = 147
- Breakdown hours = 21
- Idle hours = 300 - (147 + 21) = 132

Now, I am calculating availability as:

Availability = (Work hours + Idle hours) * 100 / Shift hours

And for utilization, I am using:

Utilization = Work hours * 100 / Shift hours

Please let me know if my calculations are correct or incorrect.

First of all, the statement is very abstract. If you need concrete solutions, then you must supply concrete facts. Otherwise, the solution or the answer will also be abstract.

For example, you have stated that shift hours per month are 300, i.e., the total available working hours.

Breaking down the hours, I suppose it refers to equipment breakdown hours, which equals 21 hours. Therefore, the machine or equipment available for production is 300 - 21 = 279 hours. It is as simple as that.

Next, you mentioned work hours, which I presume are the hours worked by individuals so far, totaling 147 hours. The effective non-utilization of man-hours is then calculated as 279 - 147 hours. However, it is not clear whether breakdown hours are inclusive of worked hours. It should be understood that if equipment breaks down due to no fault of the worker, their working hours cannot be discounted, and they must be paid. I hope this clarifies the situation.

Please ensure clarity in your problem statement.

Given the data provided in your problem statement, the effective utilization of equipment or machinery can be calculated as the hours the machine has been put into work divided by the total available hours of the machine. I hope this helps you reach a conclusion.

Thank you.
