The Simulation Modeling for Safe Use of Technical Systems (Example: Forest Machines)

Simulation modeling for the safe use of a technical system on based a probability-based algorithm with constraints has been presented. The probability-based algorithm consists of task decomposition and forming a transition matrix. The task decomposition is used to define critical subtasks for the safe use of a technical system. At each stage of using a technical system, constraints are defined based on technological regulations. The probability of successfully executing a subtask is related to compliance with technical regulations and otherwise. The transition matrix is the filled probabilities of executing for each subtask. Based on the probability-based algorithm, a simulator with immersive technologies for training forest machine operators was developed. Analysis of experimental data in the training process showed a decrease in the sum of the operator’s errors by 80%. The practicability of using the simulation modeling for the safe use of a technical sys-tem based on the probability-based algorithm in industry for training operators.
