Využití simulačního modelování v programu SIMUL8 ke zlepšení podnikových procesů

Simulation is a method used for studying complex systems that are not solvable with standard analytical techniques. Main advantage of the simulation modelling is the fact that all changes are made in virtual reality, in simulation software, without the necessity of the change in real life situation. As it is hard to follow and analyze all the processes in a company, the simulation model can be a good solution for the analysis. To perform the simulation it is necessary to map the whole process including the sequencing of activities and then set the rules for the movement of entities between the activities. Entities are dynamic objects (customers, products, documents) moving through the processes and using various resources. Afterwards all resources required or used by entities must be defined and the probability distributions of activities’ times must be selected. Business processes can be modeled in software aimed at discrete event simulation principle. SIMUL8 belongs to these types of software. This contribution describes the use of the simulation model in different situation under the support of SIMUL8 software. All the examples described above (model of the administration processes in vehicle register system, model of the shields production system, model of the camshafts production) show how the model can help to study the system and to analyze the influence of the higher demand, higher production or other changes on the capacity utilization in the system. According to the simulation results some recommendations for the company relating workers, machines or processes could be made
