<p>A task flow extraction means (13) generates task flow information in which set names of data sets are arranged in order of update time every processing. A transitional information generating means (14) specifies a transitional relation that is the relation between data sets updated in succession to generate transitional information (14a). A critical update extraction means (15) extracts update information including critical data items (12a), for the update target and specifies the correspondence relation of the data set and an update value. Every transitional relation, an influence degree computing means (16) computes an influence degree to the task from the frequency of occurrence of transitional relations and from the update value corresponding to the data set of a transition source and that of a transition destination to output influence degree information (16a).</p> |
