On-Line Production Planning Optimization Based on Message Bus of MES

An on-line optimization model is established for a large scale coal processing and town gas plant with the application of input-output analysis. This paper presents a class of MES based on the concept of message bus with the three-layer structure of plant-wide automation and management system. Determining the appropriate values to assign the parameters of the model from MES and ERP on a message bus is a critical character of the study. A lot of obstacles to implementation of the on-line optimization have been overcome and a considerable marginal profit has been achieved.
