A simulation-based optimization approach for passenger train timetabling with periodic track maintenance and stops for praying

This paper presents two optimization methods for solving the passenger train timetabling problem to minimize the total delay time in the single track railway networks. The goal of the train timetable problem is to determine departure and arrival times to or from each station in order to prevent collisions between trains and effective utilization of resources. The two proposed methods are based on integration of a simulation and an optimization method to simulate train traffic flow and generate near optimal train timetable under realistic con- straints including stops for track maintenance and praying. The first proposed method integrates a cellular automata （CA） simulation model with genetic algorithm optimiza- tion method. In the second proposed approach, a CA simulation model combines with dynamically dimensioned search optimization method. The proposed models are applied to hypothetical case study to demonstrate the merit of them. The Islamic Republic of Iran Railways （IRIR） data and regulations have been used to optimize train timetable. The results show the first method is more effi- cient than the second method to obtain near optimal train timetabling.

Cultivation of Applied Foreign Language Talents in the Context of Hubei Free Trade Zone

This paper explains that the construction and development of Hubei Free Trade Zone has brought opportunities for the employment of applied foreign language talents.It analyzes the problems existing in the training of foreign language majors in Hubei local undergraduate universities:the professional positioning is vague,the curriculum system is unreasonable;the teaching mode is relatively outdated and cannot stimulate students’interest in learning;the teaching skills are limited,and the teachers’practical ability is insufficient;Improper methods,insufficient attention to quality training,etc.In response to the above problems,the article puts forward ideas and countermeasures for training applied foreign language talents.

THE ACUPUNCTURE AND MOXIBUSTIONEXPERT SYSTEM

ABSTRACTIn order to meet the demands of the diagnosis and treatment in hospital,the research on thechannel and point time rules,the teaching request of acupuncture and moxibustion,we have designed the Acupuncture and Moxibustion Expert System. The system includes two fie:ds ofknowledge: acupuncture and moxibustion theory and its application(channel, point), the theoryand applies of the vigor and wane of QIXUE in the five internal organs (liver,heart,spleen,lungand kidney).The system consists of three subsystems:treatment system,inquiry system and teaching system.system functions:treatment system: register (provide data for medical record base), treat (provide help andsuggestion),give prescriptions (points, needle method).inquiry system:complete the require to acupuncture knowledge,apply theory,system operation, system maintenance, the timepoint, time - organ's QIXUE, time -']' GanZhi mutual relation,optimum time for acupuncture.teaching systems:complete the teaching work,it is applied to different levels,self--teaching,individual coach, imitative examination, self -- practice, self -- evaluation,teaching evaluation(step by step or series),give teaching advice,fulfil edition work.base:acupuncture knowledge base, inference rules base, data base, practice and examinationbase,procedure base,function base.user contact: base on production form,straight, contrary, straight --contrary inference way,base on frame inference way,inference tables,inacurate inference way.explanation form:context explanation,trace inference explanation.screen show form: words,image,statistics curve,table.knjwleage receiver:gain knowleage through compiling procedure learning method. The system procedure is compiled by C and Assemble language.conclusion:The system is designed for non--computer speciality people,it has the advantage of convenience for operation,powerful functionand ability of correcting mistakes.The system includes the Chinese moden experts knowkedge and experiences of dozens ofacupuncture and moxibustion experts, it has the features of rich knowledge,various kinds,it illustrates and explains thoroughly to clinic and neekle methods. It infers the best time for clinic touse needles.' The system can count up the data of medical record base,the point--time--treatment effectrelation,teaching dffect,and applying ability,it provides data for further research.The systen uses QIXUE theory and the mathematical model to providesn 8vZ~ SWIm KI+3 Z Kii-l i-u+1an assistant way to research the relationship or time rules of five organs QIXUE vigor or wane.The system has transparent,intelligence flexible character,it can be expanded.
