These components are in demand by various industries but most are manufactured for the automotive industry. Therefore, the reliability, quality and on-time deliveries of the products are challenged to still increasing volume of demand and, of course, the production quantity. In order to find the optimal organization of the relay assembly work at the workstation described, three main variants of the manufacturing time optimizing and their mutual combinations have been described and calculated in order to find the overall minimum assembly time of the product. All the appropriate tests should be kept, i.e. increasing production performance does not come at the expense of quality and reliability degradation. The results of this case study of the particular variants are presented at the end of the article. Keywords: modeling, production process, simulation, workstation. JEL Classification: C15, C63, E27, F17 1. Introduction There are many paper described about the organization of assembly workstations or cells. The vast majority are engaged in ergonomics, automation and robot-human cooperation. The strategy of assembly cell work is dealt by Chcen et al., which is devoted to scheduling using Petri nets with the simulation verification. It is a research about work organization in human-robot cooperation (Chen et al., 2011). Further research collaboration robot man comes from Tsarouchi et al. Robots and humans coexist in the same cell and share tasks according to their capabilities. An intelligent decision-making method that allows human-robot task allocation is proposed and is integrated within a Robot Operating System (ROS) framework (Tsarouchi et al., 2016). Chryssolouris and Subramaniam find a weakness in the static scheduling problem, because this solution does not consider multiple criteria, nor do they provide alternate
