Question

We need to know how effective our bottle filler operated for the past month.

Data for month:

Number of working days                                                  22

Actual elapsed time worked per day in hours                    8.5

Minutes of downtime recorded during month                     871

Rated speed (bottles per minute)                                     240                                                                      

Bottles filled                                                                   2,656,272

Bottles discarded                                                                 72,727

Assignment: Calculate the filler’s Equipment Effectiveness

Time

Rate/Speed

Quality

Equipment Effectiveness = T x R x Q             

Explanation / Answer

Time Effectiveness

T = 1- Downtime/Total Time = 1 - 871/(22*8.5*60) = 0.9224 or 92.24%

Rate/ Speed Effectiveness

R = Bottles filled / Total bottles at rated speed = 2656272/((22* 8.5*60)*240) = 0.9864 or 98.64%

Quality Effectiveness

Q = 1 - Bottles Discarded/ Bottles Filled = 1 - (72727/2656272) = 0.9726 or 97.26%

Equipment Effectiveness

E = T*R*Q = 0.9224* 0.9864 * 0.9726 = 0.8849 or 88.49%
