Simulation Of Two-stage Pricing And Inventory Problem Of Fresh Agricultural Products Based On System Dynamics

In the context of the continuous development of social economy to promote the continuous upgrading of fresh agricultural products consumption,the structural oversupply of fresh agricultural products,supply response lag and other problems still exist,the traditional marketing methods have many disadvantages at the same time the network pre-sale of new marketing methods are insufficient.Therefore,in order to improve the disadvantages of traditional marketing and network booking to implement the insufficiency,on the basis of summarizing previous research,the sales of fresh agricultural products into network booking stage and formal sales stage two stages,based on product life cycle theory two production model,build fresh agricultural inventory and pricing system dynamics model,with VENSIM software to draw two stages of fresh agricultural products production and marketing process,according to the causal loop diagram build stock flow diagram and system model definition.Qujing kiwi fruit as an example for two stages of pricing and inventory problem simulation,through the model for structural range suitability test,extreme condition test,sensitivity test and dimensional consistency test,simulation operation.According to the operation results,the dynamic process of network pre-sale and pricing is analyzed.Finally,the analysis of fresh agricultural products network pre-sale system cumulative income process.The results of the research show that: fresh agricultural products have the characteristics of high inventory cost and strong perishable,in the network pre-sale stage,the change of price discount rate directly affects the whole process of fresh agricultural products supply.In the pre-sale phase,Discount and price reduction strategy for fresh produce,Inspire consumers to buy the products supplied by the business,Thus increasing the product pre-sale sales of the enterprise,Direct to reduce surplus inventory,reduce inventory cost,reduce the amount of spoilage,Can effectively improve the consumer consumption experience,To enhance the reputation of fresh agricultural products production and supply enterprises,Establish a good corporate image;conversely,If the pre-sale price discount rate is reduced or the pre-sale price is increased,It will directly affect consumers’ product demand for their own enterprises,Reduce sales in the pre-sale phase,Increase the number of products in stock,inventory preservation cost and spoilage quantity in the official sales stage,So that enterprises have to take measures in the formal sales stage to reduce the price of promotion or even low price clearance,This is not only conducive to the profit maximization and consumer experience of the whole sales process,Make the enterprise be at a disadvantage in the next production and supply cycle.Constantly adjusting the pre-sale price discount rate to observe the change of the model obtains the price discount rate of maximizing the profit in the pre-sale stage.The case also verifies the reflection of the model to the real situation,so it has a reference value for other related products.At the same time,born fresh agricultural products online pre-sale low price and high quality marketing strategy with high quality products to create a good corporate reputation,create a good brand image,not only in this round of production and marketing process to increase revenue,in the future long-term supply process can lay a good market foundation,is conducive to the long-term development of the enterprise.Finally,according to the research conclusions,improvement suggestions are put forward from the insight of enterprise market risks and opportunities,marketing means change,product innovation and research and development,supply chain efficiency improvement and cold chain logistics construction,digitalization and information level,enterprise management level and standard management of fresh agricultural products.The research is conducive to expanding the theory of supply chain pricing and inventory theoretically,and enriching the related theory of agricultural products supply chain pricing and inventory problem simulation based on network pre-sale.In practice,the establishment of the model is simple to use,intuitive and real,which is conducive to provide some reference for the pricing of fresh agricultural products supply chain,is committed to promoting the balance of production and sales of fresh agricultural products,reduce the waste of fresh agricultural products,alleviate the disconnection between production and marketing,difficult to buy expensive problems.
