Abstract

SYSCOM is a program for the entry, manipulation and evaluation of tabular data. The following description refers to each row of a table as an "Entry", identified by an "Entry Name". Each column, identified by its "Descriptor", is termed an "Attribute". Each row column position contains a numeric "Rating". With each attribute there is associated a signed numeric "Weight".

SYSCOM An Interactive Program for System or Other Entries Comparison

SYSCOM is a program for the entry, manipulation and evaluation of tabular data. The following description refers to each row of a table as an "Entry", identified by an "Entry Name". Each column, identified by its "Descriptor", is termed an "Attribute". Each row column position contains a numeric "Rating". With each attribute there is associated a signed numeric "Weight".

The program family SYSCOM provides for the initial buildup of such a table of ratings and the subsequent addition or deletion of entries or attributes together with their corresponding ratings. Entry names, attribute descriptors, attribute weights and individual ratings may be changed. The rows (Entries) or columns (Attributes) of the table may be re-ordered in any arbitrary order or they may be graded. Attributes, for example, can be graded by ascending or descending weights. Entries could be ordered alpha-numerically or graded according to the value of same ranking function.

The system provides a function for the ranking of entries determined by the algebraic sum of the product of each normalized rating with its weight over the rating for each entry. Normalization is performed to constrict the rating range for each attribute from zero to one. When all ratings for a given attribute lie initially between zero and one, however, they are not adjusted.

To determine the sensitivity of the ranking to change in the various factors, differentiation functions are provided. These determine the change in ranking that would occur for unit changes in ratings or weights. The system provides for the print-out of the basic table, the rankings, the derivatives, entry names and attribute description.
