1. Why we observe OEE ?
Overall equipment effectiveness (OEE)Definition of Overall Equipment Effectiveness OEEis 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

2. Definition
(A)
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

(Q)
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 .
