Stdm is presented in four modules : root cause analysis , decision making , plan analysis , and situation review 本課程分為四個(gè)模塊:情景分析、原因分析、決策制定、計(jì)劃分析。
Based on the fault / failure model , we establish a new model ~ stdm ( static testability detecting model ) to measure software testability , and then design and implement a practical tool to fulfill it 基于軟件的故障失效模型,本文構(gòu)建了軟件可測(cè)試性量化檢測(cè)的stdm理論模型,并設(shè)計(jì)實(shí)現(xiàn)了基于該理論模型的可測(cè)試性檢測(cè)工具。
This thesis develops a process - based spatiotemporal data modeling method by discussing and analyzing backbone theory and characteristic of spatial process simulation and methods of integrating gis and process - based stdm 對(duì)空間過(guò)程模擬的理論基礎(chǔ)、空間過(guò)程模擬模型的特點(diǎn)、現(xiàn)有g(shù)is數(shù)據(jù)模型的局限性、基于過(guò)程時(shí)空數(shù)據(jù)模型與gis結(jié)合的方法進(jìn)行了分析和討論。
Basing on key concepts and techniques in object - oriented modeling , the thesis discusses design of object - oriented spatiotemporal data model , and entirely defines and describes spatiotemporal object types that are of concern in a stdm . organization of temporal attribute data and temporal treatment of spatial object are described . spatiotemporal object operators and spatiotemporal index are logically designed 論文對(duì)模型的時(shí)態(tài)屬性數(shù)據(jù)組織和空間對(duì)象的時(shí)態(tài)處理進(jìn)行了描述,提出作為節(jié)點(diǎn)和弧段,空間位置和范圍是它們的本質(zhì)屬性,所以只要節(jié)點(diǎn)和弧段的空間位置和范圍發(fā)生變化,則節(jié)點(diǎn)和弧段發(fā)生生亡事件。
Basing on background of urban transportation planning , the thesis presents a stdm of urban transportation and gives a special emphasis to spatiotemporal representation of point feature , line feature and area feature of transportation planning basic information , treatment of disaggregate travel data , and management of planning project 本論文以城市交通規(guī)劃為背景,對(duì)城市交通規(guī)劃時(shí)空數(shù)據(jù)模型的設(shè)計(jì)方法進(jìn)行了討論,提出了一個(gè)城市交通規(guī)劃時(shí)空數(shù)據(jù)模型。論文著重對(duì)交通規(guī)劃基礎(chǔ)信息面狀要素、線。 。
First , this paper introduces the conception of software test , testability , and some existent model used for analyzing testability . second , we analyze the merits and demerits of each model , as followed , after we particularly investigating the process of software fault leading to software failure , we put forward our improved scheme ? stdm and specify the process that it measure software testability more logically . at last , based on stdm we design and implement a stds ( software testability detecting system ) , which can be used to measure the testability of c programs , and show the detected result in different level 本文首先介紹了軟件測(cè)試和可測(cè)試性的基本概念等用于檢測(cè)軟件可測(cè)試性的理論基礎(chǔ),并詳細(xì)分析了一些理論檢測(cè)模型及各自的優(yōu)缺點(diǎn);接下來(lái),針對(duì)這些可測(cè)試性檢測(cè)模型中所存在的問(wèn)題,根據(jù)對(duì)軟件錯(cuò)誤導(dǎo)致軟件失效過(guò)程的研究分析,本文提出了一種改進(jìn)的解決方案stdm用于對(duì)軟件的可測(cè)試性進(jìn)行量化檢測(cè),文章在最后設(shè)計(jì)并實(shí)現(xiàn)了構(gòu)建在此stdm模型基礎(chǔ)之上的一個(gè)軟件可測(cè)試性檢測(cè)工具,該工具能夠?qū)源程序進(jìn)行可測(cè)試性檢測(cè)并得出量化結(jié)果數(shù)據(jù),驗(yàn)證了該模型的有效性。
