單服務排隊系統(tǒng)M精編B仿真程序

B仿真程序單服務臺系統(tǒng)MATLAB仿真排隊是日常生活中經(jīng)常遇到的現(xiàn)象。通常,當人、物體或是信息的到達速率大率時,即出現(xiàn)排隊現(xiàn)象。排隊越長,意味著浪費的時間越多,系統(tǒng)的效率也越低。在日常生活中,經(jīng)常遇到排隊現(xiàn)象,如開車上班、在超市等待結賬、工廠中等待加工的工件以及待修的機器等?？傊?排隊現(xiàn)象是隨處可見的。排隊理論是運作管理中最重要的領域之一,它是計劃、工作設計、存件,它以其強大的計算和繪圖功能、大量穩(wěn)定可靠的算法庫、簡潔高效的編程語言以及龐大的用戶群成為數(shù)學計算工具方面的標準,幾乎所有的工程計算領二、排隊模型法原理(1)顧客信息初始化根據(jù)到達率λ和服務率μ來確定每個顧客的到達時間間隔和服務時間間此函數(shù)生成顧客到達時間間隔。需要注d根據(jù)到達時間間隔,確定每個顧客的到達時刻.學習過C語言的人習慣于可以直接引用(2)進隊出隊仿真一顧客的離開時刻來確定當前顧客的等待時間、離開時間和下%總仿真時間Total_time=240;%到達率與服務率lambda=;mu=;%平均到達時間與平均服務時間arr_mean=1/lambda;sermean=1/mu;%可能到達的最大顧客數(shù)(round：四舍五入求整數(shù))arr_num=round(Total_time*lambda*2);%顧客事件表初始化events=[];%按負指數(shù)分布產生各顧客達到時間間隔sexprndarrmeanarrnum到達時刻等于時間間隔的累積和cumsumevents分布產生各顧客服務時間sexprndsermeanarrnum顧客個數(shù)，即到達時刻在仿真時間內的顧客數(shù)otaltime**************************************************************************s刻等于其到達時刻與服務時間之和entseventseventsevents1)=1;member=[1];**************************************************************************系統(tǒng)中已有的顧客個數(shù)enumbersumeventsmembereventsiielseifnumber0i刻等于到達時刻與服務時間之和sieventsieventsieventsi)=1;member=[member,i];有顧客正在接受服務，且系統(tǒng)等待隊列未滿，則gthmember間等于隊列中前一個顧客的離開時刻減去其到ntsieventsmemberlenmemeventsi刻等于隊列中前一個顧客的離開時刻加上其服sieventsmemberlenmemeventsi示其進入系統(tǒng)后，系統(tǒng)內共有的顧客數(shù)rmember=[member,i];events=number=1number=0events=Columns1through70000000000000000000Columns8through14000000000000000000000Columns15through21000000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns36through42000000000000000000000Columns43through48000000000000000000Columns36through42events=Columns1through700000000000000000Columns8through14000000000000000000000Columns15through21000000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns15through21000000000000000000000Columns43through48000000000000000000number=1number=0events=Columns1through700000000000000000Columns8through14000000000000000000000000000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns36through42000000000000000000000Columns43through48000000000000000000events=Columns1through7000000000000000Columns8through14000000000000000000000Columns15through21000000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns36through42000000000000000000000Columns43through48000000000000000000number=1number=1number=0events=Columns1through7000000000000000Columns8through14000000000000000000000Columns15through21000000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns36through42000000000000000000000Columns43through48000000000000000000events=Columns1through7000000000000000Columns8through140000000000000000000Columns15through21000000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns36through42000000000000000000000Columns43through48000000000000000000number=1number=1number=0events=Columns1through7000000000000000Columns8through140000000000000000000events=Columns15through21000000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns36through42000000000000000000000Columns43through48000000000000000000Columns36through42Columns1through7000000000000000Columns8through1400000000000000000Columns15through21000000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns15through21000000000000000000000Columns43through48000000000000000000number=1number=0events=Columns1through7000000000000000Columns8through1400000000000000000000000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns36through42000000000000000000000Columns43through48000000000000000000events=Columns1through7000000000000000Columns8through14000000000000000Columns15through21000000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns36through42000000000000000000000Columns43through48000000000000000000number=1number=0events=Columns1through7000000000000000Columns8through14000000000000000Columns15through21000000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns36through42000000000000000000000Columns43through48000000000000000000events=Columns1through7000000000000000Columns43through48Columns8through14000000000000000Columns15through210000000000000000000Columns22through28000000000000000000000Columns29through35000000000000000000000Columns36through42000000000000000000000000000000000000000number=0events=Columns1through7000000000000000Columns8through14000000000000000Columns15through210000000000000000000Columns22through28000000000000000000000Columns15through21Columns29through35000000000000000000000Columns36through42000000000000000000000Columns43through48000000000000000000events=Columns1through7000000000000000Columns8through14000000000000000100000000000000000Columns22through28000
