In this paper we use AHP mathematical theory, combining with VB6.0 software, and establish preschool children's psychological development model, and design preschool children's psychological development analysis system. In the first part of this paper we introduce the AHP structure, and discuss the principle and process of hierarchical analysis; in the second part, combining with the matrix theory we establish the mathematical model of objective function layer approximation. In order to verify the effectiveness and reliability of model, we use the VB software to do numerical simulation on preschool children's psychological development, and obtain the level nephogram and children's psychological maturity index curve of children's psychological development. It provides technical reference and the theory basis for the effect of preschool physical education on the psychological development of children.
Food supply chain is a complex process. The author develops a model that will provide both researchers and practitioners with a means of determining the optimal ordering policy for multi-products in fresh food supply chain. By using computer simulation. this paper conduct for a numerical analysis to the ordering policy of products of a food company in Hubei province to analyze the properties of total cost functions under each of the six different ordering policies and proposes an approximate optimal ordering policy of multiple products. Based on the models and analysis, it is found that agglomeration effect plays an important role in determine ordering policy of multiple products.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
