疫情下基于Petri 网的值机流程仿真建模与分析

疫情下机场航站楼增设的健康检测环节使值机流程用时变久,效率低下.对某机场航站楼值机流程现状分析,建立基于Petri网值机流程的过程模型,可靠性试验验证模型的正确性.研究发现:1)自助值机、网上值机和柜台值机方式均使旅客托运行李的时间过长;2)与柜台值机相比,其他两种值机方式旅客等待服务的时间更短,更多旅客选择.最后提出通过增设自助托运设备或值机柜台的方式减少旅客排队等待时间,缓解和改善值机流程中的瓶颈环节.

“微任务驱动教学法”在《值机流程》课题中的探究

根据技工院校学生注意力涣散、自主学习意识欠缺、学习积极性较低等现状,教师在进行教学设计时,需要设置精准适当的教学目标,采取生动有趣的教学方法、手段,应用有效的学业评价方式,以获得教学效果。但在人才培养方案及课程标准中设置的教学目标往往较大,因此,实践者提出“微任务教学”来解决这个问题。《值机与行李运输》是民航地面服务专业的核心课程,其中,《值机流程》是课程中的核心课题,本文旨在探究微任务驱动教学法的理论与实践,在实际教学中取得良好的教学效果。

Stochastic Lattice gas Cellular Automata Model for Epidemics

The aim of this study was to develop and explore a stochastic lattice gas cellular automata （LGCA） model for epidemics. A computer program was development in order to implement the model. An irregular grid of cells was used. A susceptible-infected-recovered （SIR） scheme was represented. Stochasticity was generated by Monte Carlo method. Dynamics of model was explored by numerical simulations. Model achieves to represent the typical SIR prevalence curve. Performed simulations also show how infection, mobility and distribution of infected individuals may influence the dynamics of propagation. This simple theoretical model might be a basis for developing more realistic designs.
