Factory overhead/Machinehours. If factory overhead is Rs 3, 00,000 and total machinehoursare 1,500, the machine hour rate is Rs 200 per machine hour (Rs 3, 00,000 ÷ 1500hours). Advantages: This method can be used advantageously where the machine is the major factor in production.
[email protected]The time that a machine spends in active operation is referred to as machinehours. If you operate your production floor in two eight-hour shifts every day and yourequipmentruns continuously, yourequipmentlogs 16 machinehoursa day. On a five-day work week, that's 80hoursa week, which comes out to 4,160 machinehoursper year for each ...
Influencingequipmentperformance through maintenance metrics Successful sites use key measurements to improve availability. The primary deliverable for any mine maintenance organization is availablehoursthat the operations department can use to meet its production goals. Performance in this area is reported in terms of availability.
Calculate the annual costs of these, then divide by total labor or machinehoursfor the year. This will be your overhead cost per hour. Once the above costs are calculated … you can use theformulasand guidelines below to arrive at either a “general” shop hourly rate or an hourly rate based on a specific piece ofequipment.

The simplest way to calculate OEE is as the ratio of Fully Productive Time to Planned Production Time. Fully Productive Time is just another way of sayingmanufacturingonly Good Parts as fast as possible (Ideal Cycle Time) with no Stop Time. Hence the calculation is: OEE = (Good Count × IdealCycle Time) / Planned Production Time
Mean Time Between Failures = (Total up time) / (number of breakdowns) Mean Time To Repair = (Total down time) / (number of breakdowns) "Mean Time" means, statistically, the average time. "Mean Time Between Failures" is literally the average time elapsed from one failure to the next.
Responsibility: The monthly calculation and reporting of Equipment Utilization is the responsibility of the Maintenance Planner. It is verified by the Maintenance Superintendent. Standard KPI: Equipment Utilization will be calculated as follows: OH / OH + DH + I/SH X 100 = Equipment Utilization OH = Operating Hours DH = Down Hours
(1) Total workinghoursper annum are 200 x 12 = 2,400. (2) Loading and unloading time is 10% of machine time. (3) Effective workinghoursare 2,160hours(2,400 – 10% of 2,400). (4) It is assumed that there is no consumption of electricity during loading and unloading time. (5) Interest has been treated as an element of cost.

Formula: Run Time / Planned Production Time. Example: 373 minutes / 420 minutes = 0.8881 (88.81%) Performance. Performance is the second of the three OEE factors to be calculated. It accounts for when the process is running slower than its theoretical top speed (both Small Stops and Slow Cycles).Formula: (Ideal Cycle Time × Total Count) / Run ...
