The main contributions are as follows : 1 . the torpedo weapon system is object - oriented analyzed with unified modeling language ( uml ) , and whose simulation framework made up of torpedo , carrier , target and countermeasure is built , in which torpedo ' s battle trajectory is for the center 其主要研究成果與創(chuàng)新點為:一、采用統(tǒng)一建模語言uml對魚雷武器系統(tǒng)進行面向?qū)ο蠓治觯⒘艘贼~雷作戰(zhàn)彈道為中心的由魚雷、載體、目標(biāo)和對抗器材各實體及其分系統(tǒng)構(gòu)成的仿真體系結(jié)構(gòu)。
This article introduces two representative traditional structured modeling technology and modern popular object - oriented modeling technology : the idef ( icam definition , becoming integration definition ) family of methods and unified modeling language ( uml ) . the idef0 method is used to specify function models 本文介紹了傳統(tǒng)的結(jié)構(gòu)化建模技術(shù)和現(xiàn)代流行的面向?qū)ο蠼<夹g(shù)這兩大派別的典型代表:集成定義( integrationdefinition , idef )方法系列和統(tǒng)一建模語言( unifiedmodelinglanguage , uml ) 。
Object - oriented technique such as booch , coad / yourdon , omt and jacobson was already widely accepted in object - oriented software developing field . the unified modeling language ( uml ) is a language for specifying , visualizing , constructing , and documenting the artifacts of software systems , as well as for business modeling and other non - software systems 特別值得一提的是統(tǒng)一的建模語言uml ,該方法結(jié)合了booch , omt ,和jacobson方法的優(yōu)點,統(tǒng)一了符號體系,并在許多大規(guī)模復(fù)雜系統(tǒng)的實際建模中被證明是一種非常好的軟件工程方法。
After many inventory management methods analyzed , multi - echelon inventory control model was advised to adopt in ascm unified modeling language ( uml ) is a kind of object - oriented language and has been adopted by object management group , which is good at parallel , distributed modeling 本文分析了多種庫存管理模式,建議采用多級庫存控制作為敏捷供應(yīng)鏈的庫存管理模式。統(tǒng)一建模語言是被omg ( objectmanagementgroup )采納為標(biāo)準(zhǔn)的面向?qū)ο笳Z言,擅長于并行、分布式建模,可以良好的解決ascm中的建模問題。
Exactly under this kind of condition , this thesis is on deeply into study to face to the object technique , unified modeling language ( uml ) with design the patterns " foundation , pass the right various and related realm to handle the system to proceed deep into the research after , through the analysis , induce with design , bring up the design patterns of various realms , then be used as the advanced discovering and researching 存在著大量的行業(yè)領(lǐng)域模式等著我們?nèi)グl(fā)現(xiàn)和歸檔。正是在這種形式下,本論文在深入探討面向?qū)ο蠹夹g(shù)、統(tǒng)一建模語言( uml )和設(shè)計模式的基礎(chǔ)上,通過對多種相關(guān)領(lǐng)域的事務(wù)處理系統(tǒng)進行深入研究之后,經(jīng)過分析、歸納和設(shè)計,提出多種領(lǐng)域設(shè)計模式,以作為進一步發(fā)現(xiàn)和提高的基礎(chǔ)。
In this way the author studied what the basic modeling elements of cmms , such as entity , action , task and interaction , shows to be in the conceptual model of c4isr communication networks . a series of specifications of conceptual model were established in unified modeling language ( uml ) in this paper , which can be used in constructing the formal conceptual model . the author also discussed how to perform the validation and verification of the conceptual model 論文通過任務(wù)空間概念模型( cmms )在c ~ 4isr通信網(wǎng)絡(luò)中的具體應(yīng)用,研究了cmms基本建模元素?實體、動作、任務(wù)和交互在c ~ 4isr通信網(wǎng)絡(luò)概念模型中的具體表現(xiàn)形式,制定了利用統(tǒng)一建模語言( uml )進行形式化概念建模時的一系列概念模型描述規(guī)范,探討了概念模型的驗證與校核方法。
