- Production optimization using discrete simulationPublication . Kharin, Dmitrii; Duarte, António J.S.T.; Khvatova, TatianaProduction and manufacturing setups involving lean solutions and customer driven “pull” logic (e.g. kanban systems) are more and more common. Usually, these systems allow companies to increase efficiency, quality levels, work force motivation and general productivity. Although these systems are not too difficult to plan and operate, in complex situations, even small adjustments can produce some unforeseen effects. In this scenario, discrete simulation can provide the tools to model the underlying systems and test the desired changes before implementation. In this work we modelled typical pull production systems with more or less complexity using a commercial discrete simulation software (SIMIO). Once the modelling phase was completed, different adjustments in the number of Kanban cards in the system were tested and evaluated, in order to optimize the system. Also, the final simulation model was built generic enough to be used in classroom environment to familiarize students with pull production concepts.
