OEE Analysis- (Uses data that can be gathered from a sample production run)Please perform this analysis for all key processes.

(Note: White cells must be filled in, Shaded cells are calculated fields)

Constraint Process: Example data

Operating pattern and machine data: Process 1 Proces

A. Shifts/day 1

B. Hours/shift 9

C. Minutes/shift =B x 60 540

D. Planned downtime: lunch,breaks (minutes/shift) Note: If tag relief is used, enter 0 40

E. Total planned production time/shift (minutes) =C - D 500

F. Total planned production time/day (minutes) =A x E 500G. Days/week 5

H. Total planned production time/week (minutes) =F x G 2500

Sample production run data: Process 1 Proces

I. Total minutes run 440

J. Total breakdown time + time for minor setups and adjustments (minutes) 10

K. Total number of parts made (good + bad) 60

L. Total good parts (first time through only- do not include parts that were re-processed or reworked) 59

M. Total bad parts =K - L 1

N. Actual cycle time (sec/part) =((I - J)*60) / K 430

Other data: Process 1 Proces

O. Planned cycle time-the one used for capacity planning (seconds/part) 135

P. Projected time per changeover (minutes) 0

Q. Projected changeovers per shift 0R. Projected downtime: changeover time/shift (minutes) =P x Q 0

S. Projected downtime: (breakdown time+time for minor setups and adjustments)/shift (minutes) This should agree with field J 10

T. Total projected unplanned downtime/day (minutes) = (R + S) x A 10

OEE calculation Process 1 Proces

U. Equipment Availability: =(F-T)/F 98.000%

V. Performance Efficiency =O / N 31.395%

W. Quality Rate: =L / K 98.333%

X. OEE: =U x V x W 30.255%

Capacity analysis Process 1 Proces

Y. Planned uptime (hours/day) = F/60 8.333333333

Z. Planned uptime (days/week) = G 5

AA. Planned rate of production (parts/minute) = 60/O 0.444444444

AB. Theoritical production capacity per day = Y x 60 x AA 222.2222222AC. Theoritical production capacity per week = AB x Z 1111.111111

AD. Weekly Demand 300

AE. Weekly Parts Available for Shipment = AC x X 336.1627907

AF. Daily Demand (DPV) = AD/Z 60

AG. Daily Parts Available for Shipment = AB x X 67.23255814

AH. Percent above/below DPV = (AG-AF)/AF 12.05%

Percent above/below DPV for bottleneck operation (Minimum value of AH) 12.05%

What are the process assumptions for yield, OEE, and first-run capability?
