【摘要】:決策者心理與行為對(duì)突發(fā)事件應(yīng)急響應(yīng)是否高效起到了決定性的作用。針對(duì)路況動(dòng)態(tài)變化下的地震物資調(diào)配問題,基于前景理論,分別構(gòu)建了救援中心和災(zāi)點(diǎn)決策者不同決策主體的風(fēng)險(xiǎn)感知函數(shù),以衡量決策者對(duì)缺貨和運(yùn)輸時(shí)間延遲的風(fēng)險(xiǎn)感知程度。從道路運(yùn)力評(píng)估、物資流動(dòng)、決策過程以及物資需求等模塊建立了物資調(diào)配全過程系統(tǒng)動(dòng)力學(xué)仿真模型。在此基礎(chǔ)上,分析了兩層決策者不同的決策態(tài)度(樂觀/悲觀)對(duì)應(yīng)急物資調(diào)配過程產(chǎn)生的影響,并以汶川災(zāi)區(qū)糧食供應(yīng)為例進(jìn)行仿真實(shí)驗(yàn),證明了模型的有效性和穩(wěn)健型。
[Abstract]:The decision maker's psychology and behavior play a decisive role in the emergency response. Based on the foreground theory, the risk perception functions of different decision makers in rescue center and disaster point are constructed to solve the problem of seismic material allocation under the dynamic change of road conditions. To measure the risk awareness of decision makers about shortages and delays in shipping time. The system dynamic simulation model of the whole process of material allocation is established from the modules of road capacity evaluation, material flow, decision-making process and material demand. On this basis, the influence of different decision attitude (optimistic / pessimistic) of two levels of decision makers on the process of emergency material allocation is analyzed, and the simulation experiment of grain supply in Wenchuan disaster area is carried out, which proves the validity and robustness of the model.
