Optimization of Task Pricing Based on Multiple Regression Analysis and Game Theory

Research Article of Journal of eSciences Optimization of Task Pricing Based on Multiple Regression Analysis and Game Theory Tianlong Wang1, Hongyan Bao2, Hairui Zhang2* 1College of Civil Engineering & Architecture, China Three Gorges University, Yichang, 443002, China. 2College of Science, China Three Gorges University, Yichang, 443002, China. Nowadays, the Internet is developing rapidly, while in the context of the mobile Internet Making photos to make money, a kind of self-service service mode currently has the problem of unreasonable task pricing, which leads to the failure of commodity inspection. Hence, in order to solve the problem, on the basis of a set of completed project task data and the whole registered member information provided by the company, we set up Multiple regression model and Bayesian equilibrium model by means of the mechanism analysis to determine models, big data statistical to determine parameters and considering the various factors that can affect the price of task. Not only can the models established in this paper greatly optimize the task pricing scheme, but also them do improve the task completion degree as much as possible and play a positive role in the efficiency of program operation under the premise that the total cost is basically unchanged.

Causes Affecting Parental Involvement In The Schooling Of Children

Review Article of Journal of eSciences Causes Affecting Parental Involvement In The Schooling Of Children Yayew Genet Chekol and Ketema Joro Ayane Salale University Parental involvement (PI) in the education of children is not a recent phenomenon. PI has become an established feature of education policies across the developed world. The study set to establish factors that may make parents choose not to participate in education process or unable to become more involved. The study was grounded in Epstein’s overlapping spheres of influence theory. A qualitative case study was employed. Purposive sampling was used to select (4) schools and (40) participants in Alefa district, Central Gondar Zone, Ethiopia. Findings revealed that the economic status and level of education of parents have a significant effect on children’s education. It also emerged that parents are more likely to be involved when teachers’ perceptions about role of parents are positive. The study established that PI is also influenced by age of children. The study recommends that parents be helped to appreciate the benefits of parental involvement in the learning of their children. Workshops should be established to develop the relationship between parents and their children. Keywords: Parent, education, parental involvement, school, community ...

Optimizing the Site Selection of Payment Stations Based on P-median Mathematical Model

Research Article of Journal of eSciences Optimizing the Site Selection of Payment Stations Based on P-median Mathematical Model Jiaying Yan1 *, Gaozhen Ni1 1College of Electrical Engineering & New Energy, China Three Gorges University, Yichang, 443002, China. Site selection is one of the classic problems in operations research. In this research, starting from a mathematical modeling example, a model was established to solve the site selection problem of 6 toll points in 52 cells. Taking the shortest distance between the residential area and the toll station as the objective function, this paper introduced 0-1 variables, established the P-median site selection model, and transformed the residents’ payment query problem into a linear programming problem. The Lingo software was used to solve the problem of positioning the 6 points as 1, 6, 14, 26, 28 and 36. This paper successfully applies the site selection model to the site selection of toll station, which has certain reference value to the site selection in real life Keywords: P-median Site Selection Model; Linear programming; Dijkstra algorithm ...
