Integrated Scheduling for Steelmaking Continuous Casting— Hot Rolling Processes considering Hot Chain Logistics

Algorithm 2

TSH-GA.
STEP 1: parameter initialization: population size , maximum number of iterative generations, the number of best individuals retained to the next generation, Current population .
STEP 2: generate an initial population
  Randomly generate a new individual and calculate its objective value (19).
  .
STEP 3: main loop of evolutionary process
  
   Select two individuals and from by roulette.
   Apply crossover operator to and to get and .
   Apply mutation operator to and to get and .
   .
   Select the best individuals from and select individuals from using roulette to construct a new generation .
STEP 4: output the best solution.
