摘要： PROBLEM TO BE SOLVED: To provide a program evaluation method and device and an evaluation program for applying quantitative evaluation to safety. SOLUTION: A program evaluation device allocates variables to the nodes of a graph, and when a value to be calculated by referring to a variable allocated to a certain node is substituted in variables to be allocated to the other nodes, the program evaluation device generates the dependence graph of variables to which a branch extending from a certain node to the other nodes is added, and sets an initial evaluation value "1" at the node corresponding to the variable in which an initial value is substituted, and sets an initial evaluation value "0" at the nodes corresponding to the other variables. Regarding each of nodes where any evaluation value other than "0" is set, and any flag showing that evaluation has been ended is not set, the program evaluation device adds the evaluation values of the adjacent nodes to update its own evaluation value, and calculates the total sum of the updated evaluation values of all the nodes, and generates and outputs the evaluation value of the program.
