Process Simulation and MES

Process Simulation and MES is the logical capability of designing, simulating, and operating discrete-manufacturing production — from line balancing and ergonomic studies in the planning phase through the live execution of work orders, routings, and quality checks on the shop floor. It bridges the engineering MBOM/routing into the operational world governed by ISA-95.

What it covers

• Plant and line simulation — discrete-event throughput, bottleneck and changeover studies.
• Robot programming and ergonomics — virtual commissioning of workcells.
• Routing and operations definition — linking the MBOM to work centers and resources.
• MES execution — dispatch, work-instruction delivery, e-records, electronic device history.
• Quality, OEE, and as-built capture flowing back into PLM and ERP.

Relationships (see sidebar)

• Supports the CAM Manufacturing Planning, Manufacturing Execution, and Quality Management processes.
• Implemented by systems like Siemens Tecnomatix (planning), Siemens Opcenter (execution), and DELMIA (both).
• Feeds the Digital Twin of the production system and the Digital Thread for closed-loop quality.
