Calculate, Store Share OEE
|Updated||Feb 03, 2019 (2 years ago)|
Overall Equipment Efficiency (OEE) is one of the best methods using measure performance of production facilities. Having a mobile app to calculate OEE will make our works easy. OEE Calculator from KTK Tools has some interesting features described below.
Save OEE for future reference
OEE Calculator allows you to save your data for future use. By default, all data saved to your phone/tablet. You can set up a firebase account and use the firebase database to save data. If you lose/change your mobile/tab you can easily recover your data if you used firebase DB. Otherwise, you can’t recover your data if you lose/change your mobile/tab.
One app – many machines/production lines
There is a field named Machine in this app which allow you to save your data for a specific machine using its name. If you have many machines/lines monitoring OEE, you can store and reuse them separate without any hassle because of this feature
One app – many users
Once you have set up firebase DB, you can share the firebase DB link with all within your firm/factory. Then anyone in the group check the data as soon you as you update it. No any physical sharing needed.
Share OEE is using messaging, email, Viber, etc
If you prefer not to use firebase DB and still needs to share OEE data, Use the share button on the bottom. It will allow you to share OEE data (which are available on the screen) using any method your phone supports. (email, sms, Viber, etc)

Performance % = (Total Output / Output per Hour) * 100 / (Planned Working Time – Planned Down Time – Meeting Time – Down Time)
Enter reject quantity during the period.
Enter rework quantity during the period.
Quality factor calculates using below formula
Quality % = (Total Output – Reject – Rework)*100 / Total Output
