  • System and optimization method for oil programming in a refinery through linear genetic programming and grammar-oriented programming, and readable storage medium
    Patent number: 10282173
    Abstract: The present invention is related to production schedules in a refinery and, more particularly, refinery production schedules by genetic programming in domain specific language. In this scenario, the present invention provides a method and an optimization system based on linear genetic programming oriented to grammar and with quantic inspiration using a domain specific language for the solution of oil programming problems, in addition to a readable medium comprising instructions to perform this said method. More specifically, the quantic chromosome keeps the superposition of states of all possible solutions and, through the evolutionary process and observation of quantic genes, the classical chromosome is created as a linear sequence of instructions to be performed. The performed instructions represent the scheduling.
