Integrated Scheduling for Steelmaking Continuous Casting— Hot Rolling Processes considering Hot Chain Logistics
| STAGE 1: | | STEP 1.1: enter the list . | | STEP 1.2: set the current time be 0, schedule RH process () according to , if apply. | | | | Select the earliest free RH device to process heat . If there are multiple RH devices idle, randomly select one. | | Calculate the starting time in the RH. | | Resort list according to in ascending order to get a new . | | STEP 1.3: set the current time be 0, schedule LF process () according to , if apply. | | | | Select the earliest idle LF device to process heat . If there are multiple LF devices idle, choose one randomly. | | Calculate the starting time in the LF. | | Resort list according to in ascending order to get a new . | | STEP 1.4: set the current time be 0, schedule BOF process () according to . | | | | Select the earliest free BOF device to process heat . If there are multiple BOF devices idle, randomly select one. | | STAGE 2: | | STEP 2.1: calculate and according to the schedule. | | STEP 2.2: apply linear programming solver to solve the SP-PWP model. | | STEP 2.3: output the solution: and the objective function value . |
