Problem solving method utilizing emergent clustering and case retrieval
First Claim
1. A method of selecting historical problem/solution cases for a design having a case base, comprising the steps of:
- a) creating an arrangement of anchor points that combine observed deviations from functional specifications at predefined measurement points on the design;
b) providing a set of historical problem/solution cases associated with the design;
c) modifying the arrangement of the anchor points and extracting a dynamic problem signature from the new arrangement;
d) ranking the set of historical problem/solution cases according to their similarity to the extracted signature;
e) repeating steps c) and d) until rank scoring is of sufficient quality;
f) selecting a problem/solution case based on its rank score;
g) evaluating the selected problem/solution case based upon divergence from the functional specifications; and
h) repeating steps c) through f) as necessary to identify one or more problem/solution cases applicable to the design.

Abstract
An Adaptive, Any-Time Case Retrieval process combines existing knowledge (emergent clustering, case retrieval with CRN) in a novel and advantageous way. Although ideally suited to the Digital Body Development System (DBDS), the method is applicable to any problem solving environment involving iterative simulations. Given a description of a problem to be solved, a candidate solution is applied to generate a problem solving base case. The description of the problem is modified and the modification is recorded. Candidate solutions are applied to the problem as modified, thereby generating a problem solving event case. These steps are repeated so as to rank the relevance of the cases generated to arrive at an optimal solution to the problem. In the preferred embodiment a case retrieval network (CRN) structure is used in the ranking process.
