Claims10
A method for evaluating a bid submitted in response to a bid invitation, comprising:
- upon receipt of said bid, retrieving bid invitation information from said bid invitation indicating preferences of a prospective purchaser;
- identifying an item offered in said bid to at least one requested item retrieved from said bid invitation to identify a first match;
- upon identification of said first match, comparing an attribute of said offered item with at least one possible attribute retrieved from said bid invitation to identify a second match;
- upon identification of said second match, obtaining at least one importance quantitative value using a purchaser specified importance of said attribute retrieved from said bid invitation;
- comparing an attribute value of said attribute of said offered item to possible attribute values retrieved from said bid invitation to identify two closest values, said two closest values comprising a closest higher possible attribute value and a closest lower possible attribute value;
- upon identification of said two closest values, obtaining at least one degree of satisfaction quantitative value using at least one purchaser specified degree of satisfaction of said possible attribute retrieved from said bid invitation;
- calculating a quantitative value reflecting a degree of satisfaction of said prospective purchaser with said bid using a fuzzy logic algorithm that considers said importance quantitative value and said degree of satisfaction quantitative value;
- and
- providing said prospective purchaser with an indication of said quantitative value, said indication to be a fuzzy expression.

- upon receipt of said bid, retrieve bid invitation information from said bid invitation indicating preferences of a prospective purchaser;
- compare an item offered in said bid to at least one requested item retrieved from said bid invitation to identify a first match;
- upon identification of said first match, compare an attribute of said offered item with at least one possible attribute retrieved from said bid invitation to identify a second match;
- upon identification of said second match, obtain at least one importance quantitative value using a purchaser specified importance of said attribute retrieved from said bid invitation;
- compare an attribute value of said attribute of said offered item to possible attribute values retrieved from said bid invitation to identify two closest values, said two closest values comprising a closest higher possible attribute value and a closest lower possible attribute value;
- upon identification of said two closest values, obtain at least one degree of satisfaction quantitative value using at least one purchaser specified degree of satisfaction of said possible attribute retrieved from said bid invitation;
- calculate a quantitative value reflecting a degree of satisfaction of said prospective purchaser with said bid using a fuzzy logic algorithm that considers said importance quantitative value and said degree of satisfaction quantitative value;
- and
- provide said prospective purchaser with an indication of said quantitative value, said indication to be a fuzzy expression.
