Making the Business Case: Assessment of Safety Intervention and Optimization of Resource Allocation

摘要

This paper intends to provide an overview of a statistical technique to assess a safety intervention program from a business perspective. A mathematical model is developed for predicting incident rates. The developed model could be used to better predict the allocation and optimization of resources which in turn minimizes the cost of incident prevention. The safety model is obtained using analysis of variance while response surface methodology and contour plots are used to optimize the incident rates. Overall, this model presents the foundation for the use of response surface methodology for the prediction and optimization of incident rates. This offers a new dimension into the practice of safety intervention. Safety intervention could be described as an attempt to alter or change how things are done in order to improve safety. In the industrial sector, safety intervention could be in form of a new program, practice, or initiative and idea which is intended to improve safety. Safety interventions in the work place include job redesign, training program, incentive programs for safety practices, and other administrative procedures. Safety interventions occur at different levels of an industrial safety system. In the workplace, major safety decision making and intervention efforts are often concentrated around the level of organization of the safety management system.
