APPARATUS FOR EVALUATING LIBRARY

Arrangements to evaluate maintenance easiness of a library on the basis of the number of modeling processes required to create a library shape and the number of modeling processes required to model a product by using the created library shape. Such arrangements include, in part, a library score calculating unit that calculates sum of the number of modeling processes and the number of library creating processes from the number of library creating processes calculated by the unit of calculating the number of library creating processes and the number of product modeling processes calculated by the unit of calculating the number of product modeling processes. The plurality of combination plans of library shapes to be evaluated are evaluated on the basis of the sum of the number of modeling processes and the number of library creating processes.
