Abstract

The invention relates to a method for optimized dispatching in the raw material evaporation process of chemical production and belongs to the technical field of intelligent optimized dispatching in the chemical production process. The method comprises the steps that a dispatching model and an optimization goal in the raw material evaporation process are determined and the optimization goal is optimized through the optimized dispatching method based on the self-adaptation estimation of distribution algorithm; the dispatching model is established according to the earliest completion time of raw materials machined through evaporating devices and the optimization goal is the minimized earliest completion time. By the adoption of the method for optimized dispatching in the raw material evaporation process of chemical production, the expression of the raw material evaporation process of chemical production is clear and accurate; the EDA has the self-adaptive learning capacity; the EDA can effectively overcome the shortages of sensitivity to the learning speed and dependence on the learning speed; excellent individual information is fully utilized to guide the searching direction, so that the searching width and the searching depth of the algorithm are reasonably balanced, and the quality of a solution is effectively improved.

Description

technical field [0001] The invention relates to an optimal scheduling method for raw material evaporation process in chemical production, and belongs to the technical field of intelligent optimal scheduling of chemical production process. Background technique [0002] With the rapid growth of the global economy, the development degree of the process industry has become an important indicator to measure the national industrial level. Chemical production is one of the most important components of the process industry. Chemical production realizes the appreciation of the value of raw materials through corresponding physical and chemical processing of raw materials. In chemical production, it mainly includes basic operations such as filtration, extraction, crystallization and evaporation, among which evaporation operation is the most widely used. The evaporation process is often used in the preliminary treatment of raw materials. According to literature research, about 90% of c...
