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.
How actually can look 8 hour on the machine ?

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 factor most influence :
- performance reduction

OEE
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
