Efficient decomposition strategy for scheduling of multistage production system and combined heat and power

An integrated approach, which optimizes the production and utility system simultaneously, is commonly used to arrive at an optimal scheduling solution. For the large-scale complex industrial systems, this approach requires extensive computational time. The main aim is to investigate the capability o...
