TPM Chapter 5 - How To Use OEE As KPI

In my previous blog, I talked about the definition of OEE, the losses associated with it and the calculation of OEE. In this blog I’ll be talking about how to effectively use it to create an action plan for your plant. I’ll explain the calculation of OEE with the help of some dummy data of my plant so that everyone has a better understanding about it. Let’s say we have the following data for a particular day of a month. Date Loading Time Down Time Operating Time Total produced bale weight/day Std. Cycle Time Defective quality bale weight Good Quality Bale weight/day 1 1320 200 1120 48000 0.022 1000 47000 Time is in minutes, Weight is in Kg Let’s look at each of the above column and how it is determined. 1.Loading Time: Loading Time = Available Time – Planned Downtime Now, if we consider one day then Available time = 24 * 60 = 1440 minutes  Let’s say our Daily Preventive Maintenance is 2 hours i.e 120 minutes for my line which                     would be my Planned downtime. This figure varies …

TPM Chapter 4 - OEE

In my previous blog I talked about the concept of 5S and how it can be used as an effective management tool. In this blog, I’ll be talking about Overall Equipment Efficiency (OEE) which forms the key measuring indicator of the entire TPM activity in an organization. OEE tells you about your equipment’s efficiency by determining the losses associated with it.
According to TPM, there are 16 major losses in any manufacturing unit as mentioned below: Losses Category 1 Breakdown Loss

Losses that impede equipment efficiency 2 Setup & Adjustment Loss 3 Cutting Blade Loss 4 Start-up loss 5 Minor Stoppage/Idling Loss 6 Speed Loss 7 Defect/Rework Loss 8 Scheduled Downtime loss or Planned Downtime
