Collaborative and hierarchical scheduling in the manufacturing industry

This study proposes new solution procedures for three different production environments. For the hierarchical production planning and schedule coordination, several models are developed. In a two-stage production system, the planning flow from the downstream stage to the upstream stage is assumed, and hierarchical planning models and collaborative coordination mechanisms between stages are proposed. In addition, assigning an expert planner in each stage is shown to be favorable under the assumed conditions. The role of human schedulers are also modeled and evaluated via system dynamics. Finally the planning, scheduling and rescheduling models under hierarchical skill levels of workers are developed.
