Computing system and method for controlling the execution of a decision process to maintain the data access efficiency upon receipt of an availability information inquiry

摘要

A computer-implemented reservation method and the corresponding system are utilized for controlling the execution of a decision process to maintain the data access efficiency upon receipt of a computation inquiry for availability information such as travel seats, in connection with service resources. The method utilized for controlling the execution of a decision process by a computer backend machine of a computer network upon receipt of a computation inquiry comprises 1) associating to the computer backend machine a configuration file containing at least a decision rule that drives the decision process and that is computed at least from a current value of a statistical indicator and a target value of the statistical indicator; 2) periodically obtaining an updated value of the statistical indicator; 3) upon detection that the updated value is differing from the target value, dynamically updating the configuration file which further comprises re-computing the decision rule using the updated value as new current value, and storing in real-time the re-computed decision rule in the configuration file. The method and system according to the invention can react to a rapid variation such as a growth of computation inquiries or a crisis (like a polling outage) and meanwhile to select an appropriate data source from several data sources and thus maintain the data access efficiency.
