This subsection presents the development of the RISD model by
a scheduling mechanism based on an intelligent technique to
handle production scheduling tasks at different management
levels from a holistic perspective.
Production management at different levels needs to determine
the assignment of orders to appropriate production units, as well
as the processing sequences of these orders. Fig. 5 shows the
flowchart of the RISD model for a distributed labor-intensive
manufacturing environment involving multiple plants. The scheduling mechanism in this model implements production scheduling in the distributed environment by dividing the scheduling task
into three-order scheduling problems at the following management levels:
