管理信息系統(tǒng)大綱

1、管理信息系統(tǒng)一 名詞解釋p1計(jì)算機(jī)模擬：就是利用計(jì)算機(jī)來模擬和實(shí)驗(yàn)現(xiàn)有的或還沒有的系統(tǒng)。p1管理系統(tǒng)模擬：就是利用計(jì)算機(jī)和設(shè)計(jì)好的模型對(duì)已有的或設(shè)想的管理系統(tǒng),管理策略，管理方法或管理手段進(jìn)行模擬實(shí)驗(yàn)，以便對(duì)所設(shè)計(jì)的方案進(jìn)行分析判斷，提出進(jìn)一步?jīng)Q策所需的依據(jù)。p9蒙特卡羅模擬方法：本質(zhì)上確定的問題，用隨機(jī)數(shù)去求解。p16連續(xù)系統(tǒng)：系統(tǒng)狀態(tài)隨時(shí)間連續(xù)變化的。p16離散系統(tǒng)：系統(tǒng)狀態(tài)僅在某些時(shí)間點(diǎn)上發(fā)生變化的系統(tǒng)。p19活動(dòng)實(shí)體：那些在系統(tǒng)中的位置可能隨時(shí)間的變化而變化的實(shí)體。p19永久實(shí)體：其位置在中固定不變的。p29點(diǎn)統(tǒng)計(jì)法：根據(jù)某些連續(xù)性概率分布的各參數(shù)之間存在一些特殊的關(guān)系，它們構(gòu)成的某些

2、函數(shù)可用來判斷分布的類型。p30柱狀圖法：利用圖形來試探的一種直觀方法。p32概率圖法：是一對(duì)密度函數(shù)形狀的比較和估計(jì)。概率圖則是對(duì)一對(duì)分布函數(shù)的形狀進(jìn)行比較和估計(jì)。p36x2檢驗(yàn)：擬合分布的密度函數(shù)與數(shù)據(jù)的柱狀圖間更正式的統(tǒng)計(jì)比較。p38k-s檢驗(yàn)：用觀測(cè)數(shù)據(jù)的經(jīng)驗(yàn)分布函數(shù)與所選擬合分布的分布函數(shù)相比較。p69系統(tǒng)數(shù)字屬性碼（sna）：給每類參數(shù)確定一個(gè)代碼，代碼有字母打頭，在其后面加以數(shù)字碼用來區(qū)分同一參數(shù)的不同情況，在程序中直接使用標(biāo)準(zhǔn)數(shù)字屬性碼就相當(dāng)于調(diào)用這些參數(shù)。p121終止型模擬：一個(gè)模擬模型應(yīng)在事先確定的事件發(fā)生時(shí)停止模擬。p121穩(wěn)態(tài)型模擬：一個(gè)模擬模型的終止時(shí)間是無窮大的，也

3、就是說其模擬是沒有終止時(shí)間的。p125序貫法：一種利用模擬實(shí)驗(yàn)逼近給定精度的辦法。p124計(jì)算逼近法：利用計(jì)算的方法來估計(jì)在給定絕對(duì)誤差或相對(duì)誤差的情況下，某模型模擬需要的模擬次數(shù)。p21事件步長(zhǎng)法：模擬鐘只有在個(gè)事件的發(fā)生點(diǎn)上才需要調(diào)整的事件。*管理系統(tǒng)大多數(shù)是 動(dòng)態(tài)離散隨機(jī)。二 gpss與語(yǔ)句解釋三 填空(p51-p57)generate 活動(dòng)實(shí)體advance 延時(shí)服務(wù)queue 排隊(duì)depart 離開gate savevalue 保存值transfer 條件轉(zhuǎn)向seize 搶占服務(wù)設(shè)施logic 邏輯開關(guān)test 測(cè)試語(yǔ)言initial terminate 活動(dòng)實(shí)體消失enter 進(jìn)入
