The article discusses the basic characteristics of multiversion production and also presents the problem of production of different product versions on the same production line. The car production is selected as an example of the multiversion production process. Three main branches of the production plant (the body shop, the paint shop and the assembly line) are characterized. Based on exemplary manufacturing process, it is presented, how determining proper sequence of tasks, carried out in the production system, may affect production optimization. This paper presents a problem of sequencing cars, known from the literature as the Car Sequencing Problem (CSP). It also presents the range of reduction of the CSP problem relative to the problem, which occurs on a real production line. For comparison, the structure of an exemplary industrial plant is shown. Based on the presented scheme of the cars production, the importance of use of the buffer warehouses in selected production system is highlighted. Thus, it is given the suggestion to reformulate the CSP issue. In the final part of the article, a sample method of optimization of analyzed production process, focused exclusively on paint shop, is given. This method aims to provide a minimum number of changeovers of robots painting car bodies, which, by minimizing setup times, increases the number of produced cars. It also has an impact on minimizing consumption of paint and solvent used to clean the nozzles of robots whenever a changeover occurs.
