What is Overall Equipment/Machine Efficiency (OEE): 
OEE is the framework for measure the efficiency in addition to effectiveness of a process, yesteryear breaking it downwards into 3 constituent components (Availability, Performance in addition to Quality production rate). It helps to stair out a employment in addition to hence that easily tin produce it in addition to provides a standardized method of benchmarking progress. OEE identifies the percent of planned production fourth dimension that is real productive.

Overall machine or equipment efficiency is the how to performs machine versus spec. In practically,

OEE= Availability X Performance Rate X Quality Product Rate

Where,

                      Loading fourth dimension – Down time
Availability = ………………………………………. X 100
                              Loading fourth dimension


                         Standard bike fourth dimension x Processing quantity
Performance = …………………………………………………. x 100
                                              Operating fourth dimension


                                     Processing quantity – Defective quantity
Quality production charge per unit of measurement = ……………………………………………………………. X 100
                                                   Processing quantity

Let,

• Working hours per day: x hours x threescore 2nd = 600 2nd
• Shut downwards (SD): 35 2nd
• Loading time: (600-35) = 565 2nd
• Equipment stoppage/ downwards time: (30+20+25) = 75

(a) Failure : xxx 2nd
(b) Set upwards : 20 2nd
(c) Adjustment : 25 2nd

• Operating fourth dimension : (565 - 75) = 490 2nd
• Standard Cycle fourth dimension : 0.35 min/ pieces
• Processing quantity : 550 pieces/ twenty-four hr menstruum
• Defective : xxx pieces.

Now,

                       Loading fourth dimension – Down time
Availability = ……………………………………………. X 100
                               Loading fourth dimension

    565 – 75
= ………………….. x 100
       565

= 86.72%

                         Standard bike fourth dimension x Processing quantity
Performance = ………………………………………………….. x 100
                                           Operating fourth dimension

    0.35 x 550
= ……………………. X 100
        490

= 40.35%

                                      Processing quantity – Defective quantity
Quality production charge per unit of measurement = ……………………………………………………………………. X 100
                                                 Processing quantity

   550 – 30
= …………….. x 100
     550

= 94.54%

So, OEE = Availability X Performance Rate X Quality Product Rate

= 0.8672 X 0.4035 X 0.9454

= 33.08%

Low Machine efficiency charge per unit of measurement due to man:

1. Management Losses;
2. Motion Losses;
3. Adjustment Losses;
4. Losses resulting from lack of automation and
5. Monitoring Losses
