System for optimization of insurance underwriting suitable for use by an automated system
View Patent ↗A robust system for automating the tuning and maintenance of decision-making systems is described. A configurable multi-stage mutation-based evolutionary algorithm optimally tunes the decision thresholds and internal parameters of fuzzy rule-based and case-based systems that decide the risk categories of insurance applications. The tunable parameters have a critical impact on the coverage and accuracy of decision-making, and a reliable method to optimally tune these parameters is critical to the quality of decision-making and maintainability of these systems.
1. A system for optimizing an insurance application underwriting decision, of an insurance application, in a computer implemented insurance underwriting system, the system comprising:
an input module that includes a process, represented by code, that processes an insurance application, the input module tangibly embodied in a computer device;
a processor module, tangibly embodied in the computer device, that applies the process to a plurality of certified insurance applications, including parameters thereof, to render a second decision,
where each of the plurality of certified insurance applications is constituted by an insurance application for which the system has rendered an underwriting first decision for each such certified insurance applications based on the parameters, and which each such certified insurance applications has been placed in a case base based on the first decision; and
a comparison module, tangibly embodied in the computer device, that compares, to generate a comparison, the first decisions upon which the certified insurance applications were placed in the case base, to the second decisions performed by applying the process, the comparison generating a result, the result relating to whether at least one of the decisions of the certified applications matches a corresponding underwriting decision performed by applying the process; and
outputting the result of the comparison between the second decisions and the first decisions performed by applying the process; and
further comprising a penalty module that generates at least one penalty based on the comparison of the second decisions performed by applying the process and the first decisions, the generates at least one penalty including aggregating (1) penalties for misclassifications, between the second decisions performed by applying the process and the first decisions, with (2) rewards for correct classifications, between the second decisions performed by applying the process and the first decisions;
wherein penalties for misclassification are based on a determination of number of rate classes that a second decision performed by applying the process is as compared to a corresponding first decision;
where the process is a plurality of predetermined underwriting rules; and
further comprising a redefinition module that redefines the plurality of underwriting rules based on the generated penalty and the comparison of the first decisions and the second decisions performed by applying the plurality of underwriting rules.
2. The system according to claim 1 , where the process is an application comparison of an insurance application with at least one previously made insurance application underwriting decision, and the result of the comparison is in the form of at least a two by two matrix.

4. The system according to claim 1 , where the processor module performs a plurality of insurance application underwriting decisions by applying the plurality of redefined rules to the plurality of certified insurance applications; and
the comparison module compares the first decisions and the second decisions performed by applying the plurality of redefined rules.
5. The system according to claim 1 , where the comparison module further generates a mismatch matrix, and the penalty module further:
generates a penalty matrix based on actuarial information; and
performs an element-by-element multiplication of the cells of the penalty matrix with the cells of the mismatch matrix to generate an aggregate penalty.
6. A system for optimizing an insurance application underwriting decision, of an insurance application, in a computer implemented insurance underwriting system, the system comprising:
an input module that includes a process, represented by code, that processes an insurance application, the process including a plurality of rules, the input module tangibly embodied in a computer device;
a processor module, tangibly embodied in the computer device, that applies the plurality of rules to a plurality of certified insurance applications including parameters thereof, to render a second decision,
where each of the plurality of certified insurance applications is constituted by an insurance application for which the system has rendered a first decision, which is an underwriting decision, for each such certified insurance applications based on the parameters and which each such certified insurance applications has been placed in a case base based on the first decision;
a comparison module, tangibly embodied in the computer device, that compares, to generate a comparison, first decisions upon which the certified insurance applications were placed in the case base, and the second decisions performed by applying the process;
a penalty module, tangibly embodied in the computer device, that generates and outputs at least one penalty based on the comparison of the first decisions and the second decisions performed by applying the plurality of rules, the generates at least one penalty including aggregating (1) penalties for misclassifications, between the second decisions and the first decisions, with (2) rewards for correct classifications, between the second decisions and the first decisions;
wherein penalties for misclassification are based on a rate class that a second decision is as compared to a corresponding first decision;
where the process is a plurality of predetermined underwriting rules; and
a redefinition module, tangibly embodied in the computer device that redefines the plurality of underwriting rules based on the generated penalty and the comparison of the first decisions and the second decisions, the redefinition module outputting the redefined plurality of rules.
7. The system according to claim 6 , where the process module further applying the plurality of redefined rules to the plurality of certified insurance applications; and
the comparison module further compares the first decisions and the underwriting decisions performed by applying the plurality of redefined rules.
8. The system according to claim 6 , where the comparison module further generates a mismatch matrix.
9. The system according to claim 8 , where the penalty module further:
generates a penalty matrix based on actuarial information; and
performs an element-by-element multiplication of the cells of the penalty matrix with the cells of the mismatch matrix to generate an aggregate penalty.
10. A system that optimizes a decision, of an insurance application, in a computer implemented decision system, based on a plurality of predetermined rules, the system comprising:
an input module that includes a process, represented by code, that processes an insurance application using the plurality of rules, the input module tangibly embodied in a computer device;
a processor module, tangibly embodied in the computer device, that applies the process to each of a plurality of certified insurance applications including parameters thereof to render respective second decisions,
