Method and apparatus for comprehensively evaluating the workability of multiple work types of articles

摘要

An operability or processability evaluating method and apparatus for facilitating design evaluation even by an unskilled user by determining quantitatively and definitely evaluation indexes for article or a part or parts subjected to evaluation and relation between the evaluation index and cost/time involved in operation performed on the article or a part/part. States of the article or a part/part of concern corresponding to the kinds of operations such as processing, assembling or inspection are categorized into a variety of basic elements (mX) of which the element corresponding to a relatively simple state is defined as a standard element (mXo). An index formula is prepared for determining an index (m epsilon x) indicating degree of difficulty of operation by comparing cost (mCx) and/or time (mTx) involved in operation performed on the basic element (mX) or an index (mIx) thereof with those for the standard element. A program indicating relation between the basic elements (mX) and the indexes (m epsilon x) is stored in a memory (2). Standard article having predetermined states (mo, ao, m l b) serving as the standard for the article to be evaluated is previously defined. When the cost/time involved in the operation determined in accordance with the index formula in response to the input of the basic elements (mX) or indexes for the article/part subjected to evaluation by the user increases beyond the cost/time for the standard, an operability evaluation score (mEi) indicating difficulty of operation or processing is calculated in accordance with an arithmetic program on the basis of a predetermined evaluation standard value (100) to be subsequently displayed in an evaluation form desired by user.
