【 摘 要 】

The traditional process similarity calculation method has a large amount of calculation and the calculation process is cumbersome. For the case of long process routes and long codes, the calculation difficulty and running time increase rapidly, and the operation effect is not good. In this paper, a process similarity analysis algorithm based on the longest sub-similar sequence set is proposed. Compared with the traditional calculation method, this algorithm has the advantages of high operating efficiency and strong adaptability. Further considering the influence of continuous similar process sequences, the penalty factor is introduced to improve the algorithm, so that the algorithm is more perfect and reasonable. This algorithm has significant application value in modern manufacturing systems.
