Optimization of scheduling scheme for self-driving vehicles by simulation algorithm.

As a new logistics technology, self-driving electric vehicles not only improve freight efficiency but also promote energy saving and emissions reductions. Aiming at logistics technologies based on self-driving electric vehicles, planning the vehicle scheduling scheme as a whole reduces energy consumption and improves economic and environmental benefits. Targeting an actual freight problem based on a two-way single-lane road connecting the pickup and delivery points and including electric charging stations, this paper proposes a method for optimizing the scheduling scenario and parameters of self-driving vehicles through computer simulations. An optimization model based on dynamic programming is established, and an optimization simulation algorithm is designed to solve the model, effectively solving the overall planning problem of vehicle scheduling. The experimental results show that the model and algorithm have good universality. After specifying an appropriate road length, total number of vehicles, number of spare vehicle batteries, duration of freight transportation, and other necessary information, the simulation algorithm is executed and the optimal scheduling scheme and the total amount of freight transported are output. The efficiency of the algorithm is extremely high, requiring only 1.5 s to complete the whole simulation process of scheduling 150 vehicles for 1000 h over a road with a length of 10 km.

Overall planning and optimization: characteristics analysis of the medical doctoral supervisor and consideration of the current situation of enrollment / 中华医学教育探索杂志

This study has combed and analyzed the characteristics of medical doctoral supervisors and the enrollment status from 2015 to 2018 in Tongji University School of Medicine. The results show that the distribution of doctoral supervisors' age, gender and professional title is relatively balanced. The enrollment situation shows the clustering trend. There are obvious differences in enrollment among clinical medical disciplines, and the scales of doctoral supervisors and doctoral students are not matched and unevenly distributed. It is essential to give an overall consideration in discipline resources and optimize enrollment allocation, for improving the construction of doctoral supervisors and the quality of doctoral training.

[Analysis of the Urban Water Eco-environment Protection Strategy in the Beijing-Tianjin-Hebei Region from "Three Waters" Overall Planning].

Clarifying the direction and strategy of water eco-environment protection in the Beijing-Tianjin-Hebei region is of great significance for realizing the water eco-environment protection and high-quality, coordinated development of the Beijing-Tianjin-Hebei area, as well as the goal of building a beautiful China by 2035. From the perspective of "Three Waters" overall planning, based on the urban scale of the Beijing-Tianjin-Hebei region, this study constructed six dimensions of water resources, water environment, water ecology (Three Waters), socio-economic development level, pollutant emissions, and environmental governance efforts. The water eco-environment protection strategy analysis system provided a logical framework for quantifying the current status of the water eco-environment. The ideal value was compared in each city, the PROMETHEE method was used to quantify the gap between each city and the ideal value of water eco-environment protection, and the current situation of the water eco-environment in Beijing-Tianjin-Hebei cities was evaluated. Additionally, water eco-environment protection strategies were formulated according to local conditions. The ranking of the comprehensive level of water eco-environment protection from high to low was Beijing>Tianjin>Qinhuangdao>Hengshui>Zhangjiakou>Langfang>the mean value of net flow value (Phi)>Handan>Chengde>Cangzhou>Baoding>Tangshan>Shijiazhuang>Xingtai; a large gap remained between the level and the ideal value. The hierarchical analysis showed that the advantages and disadvantages of each city's water eco-environment protection were different from dimensions to indicators, and they had the characteristics of local water eco-environment protection. Future efforts should determine the water ecological, environmental protection indicator level of each city in the Beijing-Tianjin-Hebei region, conduct a separate analysis for each city, and propose protection strategies for future development, as well as continue to help the water eco-environmental protection in the Beijing-Tianjin-Hebei region.

Practice and exploration of compact county medical consortium based on medical group / 中华医院管理杂志

The construction of compact county medical consortium is an effective way to integrate county medical resources, improve county diagnosis and treatment capabilities, and establish and improve the hierarchical diagnosis and treatment system. It is the guidance of national policy and the demand of social practice. Based on the reality of Jiangyin′s developed local economy, sufficient overall high-quality medical resources and high health demand of residents, Jiangyin People′s Hospital Medical Group explored the construction practice of compact county medical consortium according to local conditions. The group focused on implementing the functional positioning of medical institutions, improving the primary service ability, and straightening out the two-way referral process. Through the four major measures of establishing mechanism, strengthening the primary level, optimizing the process, and focusing on convergence, the group improved the organization structure and operation mechanism, continuously improved the management level and service connotation of the medical consortium. The goal of establishing an overall management mode, improving primary service capabilities, and forming an up-down cooperation mechanism had been initially realized.

Comparative Analysis on Medical Insurance for Urban and Rural Residents in Urumqi before and after the Integration / 中国卫生经济

Objective:To investigate the policy changes of medical insurance for urban and rural residents in Urumqi before and after the integration,so as to provide suggestion for the development of urban and rural medical insurance whole as plan.Methods:The health care financing after integration standards,reimbursement ratio and the changes of management methods were analyzed.Results:The personal financing standard and the starting line for patients who participated New Rural Cooperative Medical Insurance in tertiary hospitals raised after medical insurance,which effected the medical choice of patients participated the medical insurance to a certain extent.The gap between urban and rural areas affected the integration of urban and rural residents health care work.Conclusion:The level of individual pay cost should be consistent with the level of treatment in the design of ginseng protect personnel It needed to increase the government support,payment standard and treatment standard reference or innovation.

Research on approach and practice of overall medical equipment quality control testing / 中国医学装备
