Abstract: Aiming at the Open Shop Scheduling Problem (OSSP), a Memetic Algorithm (MA) is proposed to solve the problem. In the framework of the cultural Genetic Algorithm (GA), both global search and local search for the problem's own characteristics are provided. It provides a new algorithm for solving the open job shop scheduling problem. According to the thought and cultural characteristics of genetic algorithm, the method of climbing as a local search strategy into the genetic algorithm global search strategy is used, and a research of neighborhood structure is conducted on open shop scheduling problem, adding hill-climbing search method to solve the optimal. Based on the comparison of 40 standard examples, it is proved that the proposed algorithm has better performance in solving the scheduling problem with larger search space by comparing with lower bound values.
