The hereby article presents an example of application of the process mapping method in analysis of barge production logistics. The method was described briefly and the logistics of production of a barge produced in the shipyard industry were characterized. Three possible modernizations were suggested on basis of the prepared production process map that consist in technological, organizational improvements and an option that combines both of these solutions. AnyLogic program was used for comparative analysis of the suggested options in relation to the process in the base option. This is particularly important for proper drafting of the process computer models in applications for their modeling and simulation.
