Improvement of eyeglass lens production using simulation modeling and dynamic buffer optimization

The subject of the paper is the investigation of possible improvements to the process of eyeglass lenses production. The research area concerns the application of modern IT tools to the enhancement of production results, in the context of digitalization of the economy, including industry. The main objective is to improve the efficiency of the realized production process in terms of the defined quality criterion. The applied approach is based on a simulation experiment method. A computer program implementing this method was used. The results show the effectiveness and universality of the proposed approach for the studied class of problems. The main theoretical contribution to the studied field is integration of the buffer allocation issue, defined as an optimization problem, into the simulation experiment method. The practical conclusions show the benefits for the company from the perspective of implementation of the production process.
