Simulation modeling and analysis in safety 2. decision models

Journal of Occupational Accidents 3(2): 115-128
Simulation modeling and analysis in safety 2. decision models
Simulation modeling as a viable approach for dealing with complex issues and decisions in safety and health was studied. Essentials of simulation, including model design, data gathering, algorithms, documentation and simulation experiments was outlined. Fire emergency evacuation and noise evaluation were reviewed. The fire study presented a model that estimated the time required to evacuate a production area with a given geometry and a fixed number of exits. The noise study employed a model to predict the exposure level of employees working with manufacturing processes which generated different random sounds throughout the work shift. Evaluation of employee exposure to airborne radioactive materials and effectiveness of the safety organization was also studied. The 1st study defined a policy to manage a facility used in testing employees for radiation contamination. An acceptable policy was one that permitted the testing of all employees as defined under regulatory requirements, while not exceeding available resources. The 2nd study evaluated the relationship between safety performance and the characteristics of the organization, its management, its policy and communication patterns among various functions and levels. Both studies used models where decisions were reached based on the prevailing conditions and occurrence of key events within the simulation environment.
