Abstract: The present disclosure provides a flexible job-shop scheduling method and system and an electronic device. The method according to the present disclosure includes: randomly generating a plurality of flexible job-shop environments in a production job-shop according to a preset production target; constructing a scheduling strategy model of the production job-shop based on a Markov decision process; optimizing a feature extraction network, an actor network and a critic network simultaneously by using the scheduling strategy model and a plurality of data sets, and determining a scheduling plan corresponding to a maximum completion time as an optimal scheduling plan after the completion of the optimization; and completing the preset production target based on the optimal scheduling plan. According to the present disclosure, feature extraction is performed on the plurality of job-shop environments to generate a scheduling scheme, so as to improve the efficiency and rationality of flexible job-shop scheduling.
