1. Why we observe OEE ?
Overall equipment effectiveness (OEE)
Definition of Overall Equipment Effectiveness OEE
is an indicator of how a machine , production line or a
process are performing in terms of Availability ,
Performance (Speed) and Quality .
OEE 指的是生产过程中,机器,生产线或者
一个流程的生产能力的效率和质量的具体体现.

1. Why we observe OEE ?
Key requirement for stabilization and betterment
OEE are :关键设备的稳定性和OEE改进
 Strong maintenance加强维护保养
 Good molds (tools) and trim tools良好模具和相关工
具
 Stable and Manage proceses过程稳定和可控性
 Strong process TPM (Total Productive Maintenance)
加强全过程的生产保养
 Quickly change molds processes快速的模具更换流程
 Professionally schooled worker oriented on the work
in team 专业的职工队伍
1. Why we observe OEE ?
OEE is tool for measuring most important managerial parameters and
give answer of most main question
 give information about weak spots in production process
 support expansion of production (stability production
process)
 help to see production process in detail
 make possible benchmark with others companies in
branch
 OEE helps predictability in production

Planned downtime计划停机时间:
- dowtime approved management companies as planned down-time
- we could also say : planned down-time which production teams aren´t
influence
- examples :
Sampling , Mold cleaning , Machine cleaning , power cutting , planned maintenance ,
planned maintenance periphery , NO production order

OEE
Availability factor is calculated on the basis of the Planned production time
and Unplanned dowtime losses , and is the ratio of the planned production
time to the gross operating time .
Availability factor most influence :
- failures (maintenance and process) and machine defects (maintenance) ,
edfects equipments , operator errors , tool changes , unplanned cleaning ,
time for adjustment machines / tools / equipments , communications , .....
* for the easy analysis dowtime we have cods

OEE
Performance factor is calculated on the basis of the Gross operating time and the
Performance (speed) losses = difference between norm and really cycle
time

- performance reduction

Quality factor we here mean the product quality which influences the
production yield .
Quality factor is calculated on the basis of the Net operating time and
Quality . Losses due to „Defects in process“ and „Start up losses“ .
* we have cods for quality faults – FA , FU , FO .

5. Finish
OEE is the main production parameter in Plaston Group
And where else ?
5. Finish
Where is our competition ?
Qualities of best companies :
• Great experience with the measuring of losses in
production process
• Systematicle improvement
• Improving of employees qualification
