Optimization of train plan for urban rail transit in the multi-routing mode

The train plan of urban rail transit under multi-routing mode can be divided into three parts： train formation, train operation periods and corresponding train counts of each routing in each period. Based on the analysis of passen- ger＇s general travel expenses and operator＇s benefits, the constraints and objective functions are defined and the multiobjective optimization model for the train plan of urban rail transit is presented. Factors considered in the multi- objective optimization model include transport capacity, the requirements of traffic organization, corporation benefits, passenger demands, and passenger choice behavior under multi-train-routing mode. According to the characteristics of this model and practical planning experience, a three-phase solution was designed to gradually optimize the train formarion, train counts as well as operation periods. The instance of Changsha Metro Line 2 validates the feasibility and efficiency of this approach.

Consideration of Postgraduate Training under the Cross Field of Medical Information and Engineering

The slogan of“Combination of medicine and engineering”proposed in“Made in China 2025”has aroused great attention to higher engineering education.However,it is a difficult problem and challenge for schools and educators to effectively adapt to the economic and social development,train new medical and engineering talents,and explore and cultivate new subject growth points.In order to deal with engineering change and a new round of scientific and technological revolution,facing the challenge of new engineering construction.This paper will combine the reality and characteristics of colleges and universities,analyze the problems existing in the current medical engineering cross-graduate training,and put forward countermeasures and suggestions to promote the progress and development of science and technology in colleges and universities.

Control and Management in Athletic Training of the Russian National Teams

The article presents wide experience in controlling athletic training aimed at preparation of the Russian national teams for major international competitions. Experimental part of the study has been carried out in the course of training camps and competitions since 2010. Forty Russian national teams in 15 winter and 3 summer Olympic sports participated in the research. Theoretical concepts set forth in the works of Anthony Stafford Beer made a basis of a system of control and management developed for the Russian national winter sports teams. In particular, a five-level system was applied to control athletic training. The authors point out that a system of control over athletic training in elite sport teams should take into account a few important issues： （1） each sport, team and athlete has distinctive features; （2） various aspects of athletic training and their interrelation must be aimed at raising effectiveness of training according to individual training plans; （3） coaches and sport managers must be provided with real-time information necessary for development of long-term and short-term training plans and their timely correction.

A Simulated Annealing Approach tothe Train Routing and Makeup

This paper presents the formulation and solution of a train routing and makeupmodel.This formulation results in a large scale 0-1 integer programmingproblem with nonlinear objective function, and linear and nonlinearcoastraints. We know this problem is NP-complete;hence,it is diffieult to solvefor a globelly optimal solution. In this paper we propose a simulated annealingalgorithm for the train routing and makeup problem. This method avoidsentrapment in the local minima of the objective function. The effectiveness ofthis approach has been demonstrasted by results from test casee,

Optimization method of urban rail train operational plan based on O-D time-varying demand

Purpose–Under the constraints of given passenger service level and coupling travel demand with train departure time,this study optimizes the train operational plan in an urban rail corridor to minimize the numbers of train trips and rolling stocks considering the time-varying demand of urban rail passenger flow.Design/methodology/approach–The authors optimize the train operational plan in a special network layout,i.e.an urban rail corridor with dead-end terminal yard,by decomposing it into two sub-problems:train timetable optimization and rolling stock circulation optimization.As for train timetable optimization,the authors propose a schedule-based passenger flow assignment method,construct the corresponding timetabling optimization model and design the bi-directional coordinated sequential optimization algorithm.For the optimization of rolling stock circulation,the authors construct the corresponding optimization assignment model and adopt the Hungary algorithm for solving the model.Findings–The case study shows that the train operational plan developed by the study’s approach meets requirements on the passenger service quality and reduces the operational cost to the maximum by minimizing the numbers of train trips and rolling stocks.Originality/value–The example verifies the efficiency of the model and algorithm.

Annual Preparation of Young Weightlifters

INTRODUCTION： Weightlifting has its own individual features, where it is important to select new element as well as individual work with them. Ascertaining these specific features of weightlifting sport, trainers are in charge of drafting as accurately as possible the training process, which should be repeatedly realized. PURPOSE OF THE STUDY： It is recognition of the level of technical, physical and anthropometric indicators of young new weightlifters, eliminating the problems arising during the training process to advance the sporting results. MATERIALS AND METHODS： A total of 14 new weightlifters of the five sports clubs were taken into the study for a period of one year （March 2016-March 2017）. During the development of national and international activities, we showed their technical results in the style of snatch, clean and jerk, while during training showed the indicators in classical auxiliary exercises with those of strength, weight and body height. The method of comparison for reports technical-strength and weight-height with weightlifters at the European and World level of this age group was used. The data subjected to statistical processing with ANOVA method. RESULTS： The optimum coefficient of ratio： the technique snatch with clean and jerk technique at the international level is p 〈 0.79-0.80, compared to our weightlifters in the study, showed that there is oscillation from the optimum p 〈 0.001 to p 〈 0.006. The coefficient weight to height moves 13-16 cm. CONCLUSIONS： This avoidance indicates an inadequate distribution of exercises loads during the training process, most of which take snatch exercises, which do not have a good influence on the performance of the clean and jerk technique results. Loads in classical and classical assistive exercises should be distributed to rights reports for high sports achievements.

The Progress and Strategy of National Training for K-12 Teachers in China in the New Era

The reform of rural teacher team building has entered the deep-water zone where tough challenges must be met in the new era.In order to adapt to the new situation and cope with the new challenges,the national training of K-12 teachers in China should set up the concept of high-quality products,summarize the experience of the grass-roots level,aim at the prominent problems,give full play to the exemplary and leading role of the National Training Plan,and promote the comprehensive improvement of the quality and efficiency of teacher training.During the 13th Five-Year Plan period,the national training of K-12 teachers in China has achieved gratifying results,as well as considerable problems in the implementation of the National Training Plan.On the basis of sorting out the progress of the national training for K-12 teachers in the new era,this paper puts forward development strategies.
