For a Quantitative Evaluation of Risk Assessment -Behavior-based Safety

There are novel structures of society such as Industry 4.0 and Connected Industries. Under the structures, a novel safety management system considering man-machine interaction is very important topic. Safety 2.0, a new safety control, is proposed from Japan. It seems that direct and quantitative validity of risk assessment and risk reduction measure such as reinforcement of safety behavior and/or reduction of unsafe behavior is now not sufficiently accomplished. Some quantitative assessment for residual risks focusing on worker's behavior is necessary to make Vision Zero function better. We introduce to a principle of Behavior-Based Safety (BBS) which might be applicable to reduce residual risk for safety of workers. BBS, focused on behavioral modification using principle of reinforcement, is one group of Behavior Analysis of Psychology. Goals of BBS is prediction, control and quantitative measurement of target behavior.
