Abstract:
1. A method for creating a supplier rating for a supplier, the method comprising: defining an initial supplier rating matrix populated by either average supplier ratings or by ratings determined by prior knowledge of a past history of said supplier's performance relative to average suppliers; defining a first job attribute vector, the first job attribute vector including a set of sub-attributes, the set of sub-attributes including at least one of a plurality of ranges of tolerance values, a plurality of ranges of quantity values, and a plurality of ranges of times; defining a first performance vector, the first performance vector including a set of performance metrics; wherein each performance metric is based upon the supplier's performance metric relative to an average performance metric for other suppliers that perform a job; defining a first matrix; calculating the first matrix based on at least a first filter constant, the first performance vector, and the first job attribute vector; wherein said first filter constant has a value between 0 and 1; calculating a second matrix, the second matrix based on at least 1 minus the first filter constant and the initial matrix; generating a feedback matrix by adding the first matrix to the second matrix; calculating a plurality of performance ratings each corresponding to a metric from the set of metrics from the feedback matrix; and calculating a final rating value in response to the plurality of performance ratings wherein the final rating is displayed to a customer through an interface in order to assess the supplier.
