運籌學(xué)光盤內(nèi)容-實驗指導(dǎo)第八章排隊論

第八隊 程序,用于解決四種排隊系統(tǒng)的各個系統(tǒng)參數(shù)問題程序名：queue；fact(函數(shù))求階乘的函運行實例是上的例子:主要的步驟就是先運行程序,然后選擇排隊系統(tǒng)模式,然后根據(jù)提示輸入已知參數(shù),Enter鍵.第一類系統(tǒng)queue執(zhí)行實例:在命令窗口的程序執(zhí)行過程如下theprogramiswithqueueingPleaseinputthesystempattern:M/M/1/inf=1,M/M/1/k=2,M/M/c/inf=3,M/M/c/m/m=4!Pt1Pleaseinputtheaveragearrivalnumberinunittimelapta=1lapta=1Pleaseinputtheaverageservicenumberinunittimemu=2mu=2輸出結(jié)果如下Theserviceintensityofthesystemis:ru=Theaveragequeuelengthis:L=1Theaveragewaitinglengthis:Lq=Theaveragewaitingtimeis:Wq=Theaveragedelaytimeis:W=1第二類系統(tǒng)queue執(zhí)行實例:在命令窗口的程序執(zhí)行過程如下theprogramiswithqueueingPleaseinputthesystempattern:M/M/1/inf=1,M/M/1/k=2,M/M/c/inf=3,M/M/c/m/m=4!Pt2Pleaseinputtheaveragearrivalnumberinunittimelapta=5lapta=5Pleaseinputtheaverageservicenumberinunittimemu=6mu=6Pleaseinputtheparameterk=4k=4輸出結(jié)果如下Theserviceintensity(Untruth)ofthesystemis:ru=Theaveragequeuelengthis:L=TheaveragewaitinglengthLq=Thelostpossibilityp_kTheaveragelostcustomernumberinunittimeis:lapta_L=Thetruthaveragearrivalcustomernumberinunittimeis:lapta_e=Theaveragedelaytimeis:W=TheaveragewaitingtimeWq=Theaverageserviceintensity(efficentandtruth)ofthesystemis:ru_e=第三類系統(tǒng)queue執(zhí)行實例:在命令窗口的程序執(zhí)行過程如下theprogramiswithqueueingPleaseinputthesystempattern:M/M/1/inf=1,M/M/1/k=2,M/M/c/inf=3,M/M/c/m/m=4!Pt3Pleaseinputtheaveragearrivalnumberinunittimelapta=15lapta=Pleaseinputtheaverageservicenumberinunittimemu=20mu=Pleaseinputtheparameterservernumberc=2c=2輸出結(jié)果如下Theaveragewaitinglengthis:Lq=Theaveragebusyservernumberis:c_bar=Theaveragedelaycustomernumberis:L=Theaveragewaitingtimeis:Wq=Theaveragedelaytimeis:W=第四類系統(tǒng)queue執(zhí)行實例:在命令窗口的程序執(zhí)行過程如下theprogramiswithqueueingPleaseinputthesystempattern:M/M/1/inf=1,M/M/1/k=2,M/M/c/inf=3,M/M/c/m/m=4!Pt4Pleaseinputtheaveragearrivalnumberinunittimelapta=1lapta=1Pleaseinputtheaverageservicenumberinunittimemu=4mu=4Pleaseinputtheparameterrepair snumberc=2c=2Pleaseinputtheparametermachinesnumberm=5m=5輸出結(jié)果如下Theaveragehappenedmulfunctionmachinenumberis:L=Theaveragewaitingmulfunctionmachinenumberis:Lq=Theaveragebusyserver snumberis:c_bar=Theaverageworkingmachinesnumberis:a=Theaveragemulfunctionmachinetookplacenumberinunittimeis:lapta_e=Theaveragewaitingtimeis:Wq=Theaveragedelaytimeis:W=Theserveroper
