為探求此排隊(duì)系統(tǒng)的規(guī)律,首先需確定顧客流在一定時(shí)間內(nèi)到達(dá)的概率分布函數(shù)．為此,一般是通過樣本,算出均值,方差等數(shù)值,對(duì)照有關(guān)統(tǒng)計(jì)分布函數(shù)的各項(xiàng)數(shù)值,確定某一分布函數(shù)．根據(jù)我們調(diào)查獲得的數(shù)據(jù),抵達(dá)淮安支行的顧客流量大體上服從Poisson分布.
To explore the rule of queue system to determine the flow of customer first,in a certain time within the probability distribution function.Therefore,usually through the sample,calculate the mean and variance of numerical control etc,the relevant statistical distribution function,determine a distribution function.According to our survey data obtained in huaian,the customer to flow in subbranch Poisson distribution.
