Experience
Manufacturing Execution System (MES)
MES is a Windows Workflow-based control system developed for Nissan, which manages and coordinates communications with systems all across the manufacturing shop floor, enabling the just-in-time manufacturing process to operate within the factory.
Initially developed in 2014, the original scope of the system was to enable the new Infinity range of cars to be built in Sunderland by interfacing with security and coding systems in Japan and Germany, engineering data in unit assembly control, and vehicle ECU programming devices on manufacturing shop floor.
In 2017, the scope widened substantially due to a need to replace an aging 20-year-old VB6-based system that ran the production line. As a result, the scope expanded substantially to being responsible for managing, processing, and distributing vehicle spec change data between the manufacturing shop floor systems and the mainframe, data for Engine OK (engine build final line) and Engine Fit (vehicle assembly line), and miscellaneous other data (work instructions and comment data).
Finally, the system also needed to translate data formats for various manufacturing systems, including XML, flat text, and binary data formats. The final system processes over 500,000 messages per day.
