Problems solved by technology

[0013] However, in this refinement, the priority of the rules needs to be pre-specified by the expert user
This is not a noticeable improvement in runtime performance for users without expert knowledge
Also, even when expert users set the priority of rules, the set priority does not necessarily accurately reflect the actual situation
Furthermore, when the business environment changes, fixed priorities cannot adapt to the change

Abstract

The invention provides a method and a system for updating a priority of a rule processed in a rule engine. In the method, aiming at each example, the priority of the rule is calculated according to factors related to the operating time performance of the rule engine, such as a relied relationship among the rules and the execution numbers of the rules; and using the calculated priority to update the priority of the rule to make the rule with more execution number and / or relied relationships possess the higher priority. After the priority of the rule is updated by the system, the rules are sorted according to the updated priority, and the rule with the higher priority is executed first, so that the operating time performance of the rule engine is improved.

Description

technical field [0001] The present invention relates generally to the execution of rule sets, and more particularly, to methods and related systems and computer program products for updating the priority of rules to order rule set execution. Background technique [0002] In modern production activities, managers need to formulate business rules to manage production activities. The meaning of "production activities" here is very broad, and can include, for example, savings services in the banking system, sales strategies in shopping malls, cargo loading in logistics companies, network security strategies, spam filtering management in emails, and so on. In various domains, managers can formulate different business rules. For example, in the sales strategy of a shopping mall, the business rules may include rule 1: Bronze customers who spend 3,000 yuan on the same day will be directly upgraded to gold customers; rule 2: silver customers who spend 1,000 yuan on the same day will...
