Computational intelligence as a means of artificial intelligence research, has been in the areas of health workers and peasants has been widely used, and to provide a new formulation of cigarette design ideas. The proportion of tobacco leaf group formulation and sensory characteristics between showing a complex and difficult to determine the nonlinear relationship. Based on computational intelligence principle, designed on the basis of previous studies, we propose using neural network technology presents a digital cigarette formula design ideas. Firstly, from the recipe, silk craft, cigarette parameters introduced three fully formulated tobacco cigarette design. Tobacco for the current sample of the unknown is no good scientific classification method is proposed clustering method using two classical idea of ??combining both take into account the experience of experts and combined with neural networks and fuzzy mathematics method, using a sample of expertise to support vector machine, \material, the replacement of the tobacco material between the proposed new solution. Tobacco is currently a hot research designers is to find a more accurate expression of physical and chemical indicators leaf group formulation and sensory quality of comprehensive evaluation index, cigarette use this indicator to predict whether a product has been reached to requirements. In this paper, on the basis of experimental data to the physical and chemical properties of raw tobacco as an input to the sensory characteristics of tobacco as an output, the establishment of physicochemical properties and sensory characteristics reflect mapping relationship between BP neural network model and training, thereby establishing neural networks mapping model. Excluding France and paper establishes quadratic polynomial regression equation comparison results show that BP neural network is more accurate in fitting the error smaller parallel processing ability. Can effectively solve the actual production of cigarettes sensory indicators unpredictable problems. Meanwhile this paper, neural network model and Evolutionary Computation Methods leaf group program to optimize the combination formula is proposed to evaluate the absorption, combined with chemical analysis and computer-aided design of integrated solutions leaf group formula, first select the tobacco material according to the design requirements; utilization uniform design to the selected ratio, and staff through the smoking formula feeling for quality assessment, and then use BP neural network modeling; BP neural network algorithm for the S-function value in the limited predictive ability of generalization is difficult to find extreme points propose solutions. That are based on expert experience appropriate to reduce the amount of raw materials in low-grade tobacco to narrow interval; finally completed through genetic algorithm optimization formulation design, based on expert assessment after absorbing the improvement amendments designed to meet the requirements and take into account the economic optimum formulations to expect good market efficiency. In this paper, leaf group formulation design simulation, and compare several formulations sensory difference between the methods, the results prove the correctness of the design ideas in the experiments and actual production has a guiding role.
