6 Manufacturing Processes

7 Current MES model

8 MES Example SiView  Server side, all logic and application scenarios ranging from MES specification manager and material manager to web reporting. resides on an AIX platform, where the MES application is the highest level, while many industrial standard frameworks and middleware support are also included in order to support system extension and integration.

9 MES Example SiView  Client side, a thin GUI interface getting information on lot, consumables, setup, tooling, and process specifications before a process get started recording data on the process, consumed consumables, and quality assurance SiView  – IBM trademark

10 Distributed MES? Distributed computing  enabled technology Mechanisms architecture synchronization

11 Once a product is ordered and scheduled for production, a corresponding production line will be strategically and optimally formed based on the status of plant floor manufacturing systems As soon as the product gets finished, the line will be dismissed and all the equipment in the line will be optimally reallocated Virtual Production Lines
