Chemical production planning and scheduling integration under demand uncertainty
Production planning and scheduling are two of the most important decision-making problems in supply chain optimization. To ensure the efficiency of decision-making
planning and scheduling were integrated
with consideration of demand uncertainty. For a multi-period production planning and scheduling problem
planning and scheduling deterministic models were established in each period firstly
and they were integrated through production correlation. Then
demand uncertainty was introduced and decision variables were represented with a finite number of scenarios in a two-stage stochastic programming model. At last
rolling horizon strategy was used to achieve consistency between planning and scheduling results in an iterative process. The case study demonstrated that compared with the conventional method
the stochastic programming method could reduce total cost under demand uncertainty. Combined with the hierarchical integration method
production operational and economic optimization was achieved.
