EXHIBIT 11.1 - EARNINGS PER SHARE COMPUTATION


Earnings per share calculations may be affected by the granting of stock options
under the provisions of MPSI Systems Inc. Stock Option Plans. The granting of
these options may have a dilutive effect on earnings per common and common
equivalent share. Following is a summary computation of the average number of
shares outstanding and earnings per share using the treasury-stock method.
