The sequence diagram in Figure 5 depicts a streamlined process for initiating a job on a wire harness machine. Unlike the previous example, where parts and article information were added in separate steps, this approach consolidates the workflow by sending all necessary information along with the job creation command.

StoreAndStartJob: The MES sends a single StoreAndStartJob command to the machine. This command is comprehensive, containing all necessary data required for the job: 'ArticleSpec A,’ ‘Part 1-3,’ additional process input data, and the number of runs, which is set to 10 in this scenario. This encapsulation of data reduces the number of communication steps between the MES and the machine, leading to a more streamlined operation.

Processing and Feedback: As the job starts, the machine processes the information and begins the manufacturing runs. Feedback is then provided to the MES after each process is executed:

Result Process A Run 1: Details from the first run of Process A are sent back to the MES.

Result Process m Run n: As subsequent processes are completed, their results are also reported back to the MES in real time.

Job Result (KPI Details): At the conclusion of the job, a comprehensive report including KPI details is transmitted to the MES. These KPIs provide valuable insights into the performance, efficiency, and quality of the executed job.
