摘要： 針對(duì)應(yīng)急疏散行為受社會(huì)化屬性驅(qū)動(dòng)而表現(xiàn)出不確定性、互動(dòng)關(guān)系復(fù)雜等特征,基于Cell-DEVS語(yǔ)言構(gòu)建人員疏散系統(tǒng)仿真模型,模型在強(qiáng)化描述行人運(yùn)動(dòng)能力的基礎(chǔ)上,引入環(huán)境熟悉程度、個(gè)體視野、溝通與引導(dǎo)及速率區(qū)塊等社會(huì)化互動(dòng)因素,旨在優(yōu)化模型算法,完善個(gè)體與環(huán)境,個(gè)體之間互動(dòng)關(guān)系的描述。RESTful web service遠(yuǎn)程仿真結(jié)果進(jìn)一步證實(shí)了社會(huì)化互動(dòng)的存在,提升了模型對(duì)疏散系統(tǒng)的描述能力,仿真結(jié)果更為可信。進(jìn)一步顯示了模型驅(qū)動(dòng)理論與計(jì)算機(jī)仿真技術(shù)在建筑設(shè)計(jì)、應(yīng)急方案制定、公共安全與危機(jī)管理等領(lǐng)域的先進(jìn)性與可行性。
This paper aims to present a Cell-DEVS model for emergency evacuation systems, which behave uncertainty and are intricately driven by the social factors. The model introduces social interaction factors such as familiarity degrees, individual vision, communication and conduction, and velocity zones as the state variables, describing the relationship between the evacuees and environment, as well as the interactions with each other. The algorithm optimization enhances reality of simulation. The RESTful CD++ is applied as middleware to execute remote simulation. The results confirm the existence of social interaction. This work benefits to the architecture design, evacuation planning and public safety management.
