3、<p><b>　　建立信息管理系統(tǒng)</b></p><p>　　在行政管理機構信息是個重要資源。及時有效的重要信息對于高效管理職能的表現是至關重要的，例如準備，組織，領導，控制。在一個管理機構中，信息系統(tǒng)就像是人體中的神經系統(tǒng)，它把組織的所有元件連接在一起而且還在競爭的環(huán)境中提供更好的操作和生存機會。</p><p>　　信息系統(tǒng)經常提及一個以計算機為

4、基礎的，被設計成支持組織的操作、經營和決策功能的系統(tǒng)。在組織中信息系統(tǒng)為決策者提供信息支持。信息系統(tǒng)包含交易處理系統(tǒng)、管理信息系統(tǒng)、決策支持系統(tǒng)和戰(zhàn)略的信息系統(tǒng)。</p><p>　　信息由經過處理的而且是對用戶是有用的數據組成。一個系統(tǒng)是為了達成一個共同的目的共同操作的一組元件。因此一個管理信息系統(tǒng)收集，傳送，處理，儲存，而且在組織資源、程序表和成就上儲存數據。系統(tǒng)進入經營信息之內為這些數據做合理的變換為決策者

5、在組織里面的使用。因此，一個管理信息系統(tǒng)提供支持組織管理職能的信息。</p><p><b>　　一、基本的概念</b></p><p>　　1、數據和信息的比較</p><p>　　數據提供未加工的、不被評估的事實數據、符號、物件、事件等等。數據可能是一個在于儲存事實的集合物件，像一個電話目錄或者實施統(tǒng)計調查記錄。</p>&l

6、t;p>　　信息是那些已經進入一個有意義的，有用的背景而且傳達到一個使用它做出決斷的接受人的數據。信息涉及智慧或知識的交流和接受。它評價而且通知，吃驚而且刺激，減少不確定，現實另外可供選擇的方案或者幫助去除無關的或者沒用的信息，還影響人們并且鼓勵他們做出行動。數據的元素在一個特殊的背景下可能構成一條信息；例如，當你想聯系你的朋友的時候，他或者她的電話號碼就是一條信息；除此之外，它在電話號碼薄里僅僅是一個數據的元素。</p&g

7、t;<p><b>　　2、信息的特性</b></p><p>　　好信息的特性是中肯的、時間性、準確性、成本效益、可靠性、可用性、無遺漏和凝聚層次。如果它引導改良的決策，信息是有關的。如果它重新確定之前的決定它也是有關的。如果它對你的問題沒有任何幫助那它就是無關的。例如，如果你在一月考慮去巴黎，那有關巴黎一月的天氣情況的信息對你來說就是有關的。否則，這信息就是無關的。<

8、/p><p>　　時間性涉及到信息的流通呈現給使用者。數據或信息的流通性是事件發(fā)生到它呈現給用戶（決策者）之間的時間缺口。如果這個合計時間很短，我們說這個信息系統(tǒng)是一個即時系統(tǒng)。</p><p>　　準確性是通過對數據和實際事件的比較而被測量的。準確無誤的數據的重要性隨著需要做出決斷的型態(tài)而改變的。工資總支出信息必須是精確地。簡單的近似值是不能滿足需要的。不過對于全體員工的時間有多少是專注于特

9、定的活動需要一個大致的估算，這是不可或缺的。</p><p><b>　　3、信息的價值</b></p><p>　　在決策的制定上信息有著重要的作用，因此它的價值緊緊系在使用它所做出的決斷上。信息沒有一個絕對的萬用價值。它的價值關系到使用它的人們，當它被用，和在什么情況下被用。在這個意義上，信息跟其它的商品有相似之處。例如，對于一個在撒哈拉沙漠的人來說一杯水的價值就

10、超過了一個在北極冰川迷路的人。</p><p>　　經濟學家從招致生產或者獲得商品的一個商品的成本或者價格來辨別價值。很顯然，產品的價值肯定比它的成本或者價格高讓它變得有成本效益。</p><p>　　信息的標準價值的概念已經被經濟學家和統(tǒng)計家發(fā)展而且它起源于決斷理論。這個理論的基本前提是我們總是有一些與我們的決斷相關的發(fā)生的事件的初步了解。額外的信息可能修改我們對事情發(fā)生或然率的觀點，因

11、此改變我們的決定并且期望決定取得成功。因此，額外的信息的價值是通過減少將來的事件的不確定性而獲得預期結果的差額。</p><p>　　信息支持決定，決定觸發(fā)動作，而動作影響組織的成就或績效。如果我們可以測量出績效中的差額，我們就可以追蹤信息的影響力，進而可以假設測量小心地被執(zhí)行，在變數之中的關系定義得好，而且不相關因素的可能結果被孤立。由于信息的因素，績效標準的差額叫做信息的現實價值或者顯示價值。</p&g

12、t;<p>　　對于大部分的信息系統(tǒng)來說，特別是那些支持中層和最高管理部門的人們，產生的決斷時常與不嚴格被定義而且包括不能夠被定量的或然率的事件有關。決策程序時常是模糊的，而且結果因多重的、無比的大小而依比例決定的。在一些情況下，我們可能嘗試執(zhí)行一個多屬性分析或者得到一個大體上主觀的價值。主觀的價值反映了人們對于信息的綜合印象和他們愿意為特定信息支付的價值（Ahituv, Neumann, & Riley, 199

13、4）。</p><p>　　4、對于決策來說信息是一個助手</p><p>　　西蒙（1977）把決策的程序說成是包含四個階段： 智力、設計、選擇和評論。智力階段包含與組織和它的環(huán)境有關的數據的集合物件、分類、加工和說明。這對于識別環(huán)境需求的決策是很重要的。在設計階段期間，決策者提出可供選擇的方案，每個解決方案都包含一系列需要被執(zhí)行的動作。在智力階段被收集的數據現在被統(tǒng)計，其他的模型為每一

14、個選擇預測可能發(fā)生的結果。每一個選擇也要從技術可行性、行為可行性和經濟可行性方面去檢驗。在選擇階段，決策者必須要選擇出一個對組織的目標貢獻最大的方案。經過選擇可以讓經理受制于實施和監(jiān)聽期間并且從錯誤中學習。信息在決斷程序的所有的四個階段中扮演著重要的角色。</p><p>　　5、管理信息系統(tǒng)的分類</p><p>　　管理信息系統(tǒng)有多種類型。梅森和斯旺森（1981）把管理信息系統(tǒng)分為四個

15、類型：（1）數據庫信息系統(tǒng)，（2）預言性的信息系統(tǒng)，（3）制定決策的信息系統(tǒng)，（4）決策執(zhí)行的信息系統(tǒng)。這個分類是以在決策制定的過程中信息系統(tǒng)可以提供的支持程度為基礎的。Sachdeva（1990）綜合地呈現了這四種類型：</p><p>　　數據庫信息系統(tǒng)。這類信息系統(tǒng)的責任是觀察，分類而且存儲那些對決策者可能有用的任何數據項目。</p><p>　　預言性的信息系統(tǒng)。這一個系統(tǒng)隨著時間

16、的過去超越純粹的數據收集和傾向的決定。 預言性的信息系統(tǒng)為與做出決策相關的推論和先前預測的事物提供制圖。如果上述的例子會被這樣用，那么為先前預測或者畫理論圖獲得有用的信息就是可能的。</p><p>　　制定決策的信息系統(tǒng)。這個系統(tǒng)距離決策制定的程序更近一步，而且它包含組織系統(tǒng)的價值或這它是各種可供選擇的方案的選擇標準。一個組織的額外價值有很多而且形式多樣。它們包括解決農民問題，增加和規(guī)定了農民的基本收入，提高農

17、民的生活質量的焦慮。但是她們也包含、規(guī)定了 農民的基本收入和改善農民的生活質量。但是他們也含一個為職員好好地提供（訓練、適當的薪金，等等）意圖和在鄉(xiāng)下的經濟發(fā)展的程序中提供援助的意圖。 </p><p>　　決策執(zhí)行的信息系統(tǒng)。決策執(zhí)行的信息系統(tǒng)的例子在擴充的組織中是不容易被找到的。在信息系統(tǒng)中它是一個決策系統(tǒng)而且決策者只有一個而且是同一個。對于系統(tǒng)本身，它基本上可以削弱它增加動作的權利，因此在這個系統(tǒng)中，當假設

18、被結合的時候，經營是如此的自信。飛機加載的自動飛行系統(tǒng)就是決策執(zhí)行系統(tǒng)的一個案例。一旦飛機被啟動，系統(tǒng)自身就會保持飛機在正確的方向上，以適當的速度和高度（依照飛行員決定的參數）飛行。另外一個決策執(zhí)行信息系統(tǒng)的例子是在調制解調器工廠的生產中被應用。在汽車生產中，通過計算機汽車零配件的清單被連續(xù)不斷的保存就像汽車移動走的流水線一樣。當其他部分需要零配件的時候，計算機就會自動的下命令。這是不需要管理者的介入的。</p><

19、p>　　二、在農業(yè)擴充的管理計劃中MIS的角色</p><p>　　國家的擴充系統(tǒng)，尤其是在發(fā)展中國家，一般傾向于很龐大。例如，在印度，國家的農業(yè)延伸系統(tǒng)雇傭了大約125000人。在不同層次擴充的管理者需要相關的信息來做出高效的決策。如果缺少了這些信息，那么他們的決策也僅僅是依據他們的最基本的直覺和以往的經驗。那些經過處理，存儲和合理出現的數據會輔助他們分析問題和做出高效的決定。</p>&l

20、t;p>　　就像上面所建議的那樣，在每一個管理程序的過程中，管理者需要信息去幫助他們做出高效的決策。這樣的信息我們叫做管理信息。它不包含純粹功能上的信息或者技術上的信息，像是大米或者小麥耕種的常規(guī)軟件包。管理信息是管理者必須的信息，就像他們做出決定，比如按類別要擴充的人員就業(yè)的數目，他們的培訓要求，職業(yè)發(fā)展規(guī)劃，工作說明，預算，預測，基點審視，報道被服務的人們的社會經濟狀況，和目前的設備（Ramesh Babu & Sin

21、gh, 1987）。</p><p><b>　　三、需要自動化</b></p><p>　　一個自動化的信息管理系統(tǒng)包含的數據僅僅像是由手工系統(tǒng)做出來的。它接收輸入，加工輸入，和遞送像輸出一樣的加工輸入。當其他的要求數據被記錄在一個輸入媒介比如磁性材料（特別地涂上一層的塑料易曲的或軟式磁盤和磁帶）上時一些輸入設備允許直接的人機交互。直接地被連接到一部計算機的工作區(qū)的

22、鍵盤就是直接輸入設備的一個例子。自動化的使用讓存儲大量的信息變得有可能，而且還避免了找到他們手工記錄的路徑時的錯誤，還有那些在人工系統(tǒng)中實際上是不可能比較和計算的錯誤。</p><p><b>　　四、數據庫的組織</b></p><p>　　數據通常是經過交易處理系統(tǒng)在欄位層次上產生的，但是一旦信息被取得，假如信息需求已經很好的被定義，適當的程序表已經被執(zhí)行，而且一

23、個方法已經被安排為共享數據，那么任何組織領導層的延伸階層都可以使用它們。這就暗示著同一個數據可以同時被多個不同集合的程序表所使用；因此，我們可以看出數據（數據的集合）和應用（程序的集合）的區(qū)別。在一個決策支持系統(tǒng)（DSS）中，一系列的程序集是模型的基礎（Keen &Morton，1978）</p><p>　　期間數據庫可能提及可以為一個機構內各部門服務的數據集合。在給定的題目上的數據庫是一個數據集合，在

24、那個給定的題目上要遵循三個準則：廣泛性（完整性）、非冗余的、和適當的結構。廣泛性意味著所有關于數據的題目都在數據庫中實際出現過。非冗余意味著早數據庫中每個獨立的數據條只存在唯一一次。適當的結構意味著數據用一種像是使最小預期加工和存儲成本的方法進行存儲(Awad & Gotterer, 1992).。</p><p>　　能夠靈活的被那些應用程序或者樣板基層共享的大型企業(yè)的數據庫的想法已經被那些軟件包特別是

25、執(zhí)行如此認為的軟件包所了解。這些被叫做數據庫管理系統(tǒng)（DBMSs）的包在不同商品名稱下面的市場中都是可得的，比如ORACLE, SYBASE, INGRES, FOXBASE, and dBASE. </p><p>　　五、以計算機為基礎說明的MIS</p><p>　　一個國家農業(yè)擴充系統(tǒng)是被國家政府管理的全國范圍的系統(tǒng)。在印度，在全國性和狀態(tài)層次之間的權力分割之下，農業(yè)是一個政府話題

26、。然而，國家政府補充財政資源的狀態(tài)而且在國家的層次上提供調和。政府的行政機構被劃分為區(qū)域，區(qū)域進入細分之內，進入區(qū)塊之內的細分。一個區(qū)塊是一組村莊的集合，也是農業(yè)擴充程序表管理的基本單位。在區(qū)塊層次收集的數據需要在高級的管理層次被整合，在區(qū)域和州的層次上提供一個整合的意見用以支持計劃、監(jiān)聽和決策制定。</p><p>　　然而，實際的設計可能會隨著政府的大小和其他因素而改變。為了整個的政府，一個整合的數據庫可能在

27、政府總部被一個主機/迷你計算機所支持。為了數據的分析，適當的程序表可能被設計成在狀態(tài)層次提供交互式決策支持系統(tǒng)。根據要處理的數據的容量，每個區(qū)域和細分有可能具有一臺迷你/微計算機。在區(qū)域和細分的計算機很有可能與政府計算機同屬于一個網絡。在區(qū)域/細分本地數據可能被存儲和處理，而被共享的數據可能會以適當程度的聚合被傳送到政府總部更新整合的數據庫。區(qū)域和細分會通過他們的密碼使用指定給他們的適當的權限直接訪問整合的數據庫。區(qū)塊可能只使輸入-輸出

28、終端機被連接到細分計算機為區(qū)域提供數據，有必要的時候作為在線查詢。</p><p><b>　　附件2：外文原文</b></p><p>　　Establishing a management information system</p><p>　　Information is a critical resource in the opera

40、ggregation level. Information is relevant if it leads to improved decision making. It might also be relevant if it reaffirms a previous decision. If it does not have anything to do with your problem, it is irrelevant. Fo

56、Simon (1977) describes the process of decision making as comprising four steps: intelligence, design, choice, and review. The intelligence stage encompasses collection, classification, processing, and presentation of dat

59、and Swanson (1981) describe four categories of management information systems: (1) databank information system, (2) predictive information system, (3) decision-making information system, and (4) decision-taking informati

60、on system. The classification is based on the level of support that the information system provides in the process of decision making. Sachdeva (1990) comprehensively presents these four types of systems: </p><

62、tive Information System. This system moves beyond pure data collection and the determination of trends over time. Predictive information systems provide for the drawing of inferences and predictions that are relevant to

63、decision making. If data from the above examples were to be used in this way, it is possible to obtain information useful for making predictions or for drawing inferences. </p><p>　　Decision-Making Informati
