Issue

Different MES systems are used across Syensqo plants. PI by OSISoft and Aspentech MES are the most common ones. Some other plants are running without an MES system, and some plants are using their MES only for a subset of production lines and functionalities.

Within the ERP Rebuild project, there is the opportunity to introduce SAP Digital Manufacturing as MES system and leverage its introduction for further functionalities.

An overview of the SAP DM functionalities can be found here:  https://docs.google.com/presentation/d/1fPfP5u_AFSuXtLUswS2qS2NFU-jj82l6/edit?usp=drive_link&ouid=112863035388257143536&rtpof=true&sd=true

Recommendation

We recommend Option 1: keep current MES systems in place. For the plants and production lines currently without an MES, we will define in Detailed Design a Decision Tree, that will contain the following options:

• continue working without MES system and use S4/HANA Fiori Apps to book production actual data
• continue working without MES system and use Mobile devices on Neptune to book production actual data into S4HANA
• roll out one of the current MES systems already used by Syensqo
• implement SAP Digital Manufacturing - Execution on the plant

Background & Context

SAP DM-Execution is a modern, fully scalable and Cloud based MES system. Its introduction would allow the usage of advanced functionalities like:

• Edge points, to allow local plants to work offline in case of connection outages or system maintenance, 
• Insights, to exploit the maximum value of the production data and identify all the bottle-neck and pain point in the current production activiites and put in place corrective actions, then measure the effect of those actions
• Production Process Designer, to define and automate production steps
• Production Connectivity Model, to use the MES system likewise a PCS/BCS system and monitor/change the parameters of the machines in the Shop Floor (e.g. temperature of an oven, speed of flux of a certain material into a reactor, etc.)
• Resource Orchestration: to automatically assign the right people and the right machines and tools to the planned production activities and optimize their utilization
• Operator Dashboard: to provide to each operator

Assumptions

• Changes of the local MES systems have a huge impact on the daily production activities
• Current Star Tek Layer heavily relies on current MES systems
• SAP DM has native integration with the new ERP system S4/HANA
