Problems solved by technology

However, there are still few calculation methods used to solve production scheduling problems. Genetic algorithm and hybrid genetic algorithm are a kind of stochastic optimization algorithm successfully used to solve small-scale scheduling problems earlier, such as the Jobshop problem, but their calculation speed is faster than traditional method calculations are much slower, which seriously affects the use of these new methods

Abstract

The invention relates to a gas-oil blending optimized deployment method that is calculated on the basis of resembling the Golgi membrane. The method is characterized in that: (1) under the condition of a blending model with high prediction accuracy and the constraint of production deployment, the invention forms a gas-oil blending deployment model for the sake of making benefit and satisfying the constraint according to the information related to blended component oil, product oil and market demand and supply; (2) adopting highly efficient calculation method resembling Golgi membrane. The calculation structure comprises the structure resembling Golgi membrane, seven calculation rules that are regularly distributed and a collection of variable objects; (3) configuring and searching for a formulation according to the span of a algorithm parameter, verify the formulation attained and start up the production. The invention provides the gas-oil blending optimized deployment method for one day and a plurality of days. The invention has the advantages of: random search of formulation within the scope of production constraint; fast finding of formulation with high quality and high profit; minimal inventory; directviewing method; easy operation, and; expansion of the scale for optimized deployment.

Description

technical field [0001] The invention relates to a gasoline blending optimization scheduling method based on pseudo-Golgi film calculation. Background technique [0002] Gasoline production can be divided into two stages: gasoline component production and gasoline blending. With the global energy shortage and the improvement of environmental protection requirements, there is an urgent need to produce and use new formula gasoline. On the one hand, refineries adopt advanced equipment and technology to improve the output and quality of gasoline, and on the other hand, they use blending methods to maximize the production of gasoline with the lowest cost. High-quality gasoline of acceptable quality. [0003] Gasoline blending is a complex industrial process with huge profit margins. Gasoline blending is the process of mixing gasoline components with some additives, such as figure 1 shown. In actual production activities, periodic gasoline blending scheduling needs to consider ...
