Application and validation of NSGA-II for designing batch production in mass customised steel industry

In recent pandemic situation the work orders from various customers are not stable due to the fact that the money flow is not happening as it was earlier. The work is based on unstable demand from customers of mass customized medium scale steel products manufacturing and leading exporters of precision components such as guide bush, steel collet, and feed finger. The industry considered for this work located in Coimbatore, South India follows a batch production system. Due to uncertainty in today’s market the industry is unable to deliver the orders within the due date. Poor production planning is found out to be one of the reasons for not being able to keep up to the deadlines. The Non Dominated Sorting Genetic Algorithm (NSGA II) is applied to produce a set of solutions with makespan and tardiness cost. Then the Analytical Hierarchy Process (AHP) has been used to validate the results obtained.
