<p>PROBLEM TO BE SOLVED: To provide a predictive system, a predictive method and a recording medium for grasping a process which may lead to dangerous work in working as the chain of changes in a time series working procedure or in working environment, time-sequentially analyzing the causal relation of these changes and predicting the dangerous work. SOLUTION: The decomposition of a working procedure to be analyzed and the arrangement of the sequences are performed (step 101), the causes of a disaster are extracted, the causal relation of these causes is arranged (step 102), the working processes are connected with the causes of the disaster (step 103), and the connected state is expressed by a Petri net (step 104). Simulation concerned with the work is performed by using the Petri net (step 106), a working method, a working environment or the like is improved (step 108) and the processing is repeated until prescribed safety is satisfied.</p> |
