Abstract

The invention discloses a multitask scheduling optimization method of a knowledge service in the cloud environment and a scheduling system constructed via the method. According to the method, an optimization objective function and constraint conditions of multitask scheduling of the knowledge service in the cloud environment are determined, and an objective is optimized on the basis of a multi-group bidirectional driving cooperative search algorithm in the big data environment. A dynamic random function is introduced into knowledge service time of the optimized objective, the dynamic random characteristic of the service time in the practical operation process of the platform can be simulated effectively, the adaptation to the dynamic and random performances of the knowledge service processof the scheduling optimization algorithm is embodied, and the response efficiency of the knowledge service process is improved; and a mapping relation between a particle position vector and knowledgeresource distribution is established in a binary coding manner, the optimization algorithm is mapped into a discrete data space, a multi-group bidirectional driving mechanism is used to realize cooperative interactive searching between a common group and a model group, the algorithm is more adaptive to the random scheduling task, and the problem in optimization of multitask scheduling of the knowledge service is solved effectively.

Description
