Since autumn 2015, our laboratory cooperates with Hoya Szemüveglencse Gyártó Magyarország Ltd. within the topics of simulation analysis and „Industry 4.0”. The primary goal of the project is to model different segments of the company’s plant in Mátészalka, according to different capacity planning and process improvement criteria. Within the developments and workshops of the cooperation, the engineers of Hoya picked up the basics of simulation modelling, enabling them to use this technology in the everyday practice.
