基于Delphi的試卷智能生成系統(tǒng)設(shè)計(jì)
摘要：運(yùn)用可視化軟件Delphi來開發(fā)試卷智能生成系統(tǒng)。是利用其提供的各種面向?qū)ο蟮拈_發(fā)工具來建立系統(tǒng)應(yīng)用原型，然后進(jìn)行需求迭代，通過不斷修正和改進(jìn)，直到形成滿意的可行系統(tǒng)。該系統(tǒng)結(jié)構(gòu)良好、使用方便、題庫(kù)數(shù)據(jù)輸入簡(jiǎn)單,系統(tǒng)能夠?qū)崿F(xiàn)自動(dòng)抽題和手動(dòng)選題兩大功能。 開發(fā)內(nèi)容包括后臺(tái)數(shù)據(jù)庫(kù)的建立、維護(hù)以及前端應(yīng)用程序的設(shè)計(jì)兩個(gè)方面。該系統(tǒng)有安全的用戶登錄模塊、易于操作的功能模塊以及方便快捷的瀏覽界面。本文的分析基于知識(shí)點(diǎn)的試題庫(kù)結(jié)構(gòu)基礎(chǔ)上，闡述以知識(shí)點(diǎn)難度系數(shù)、章節(jié)、題型為主要控制參數(shù)的組卷算法的建立與實(shí)現(xiàn)方法。該系統(tǒng)的運(yùn)用不僅提高了教師的工作效率,而且可以實(shí)現(xiàn)真正意義上實(shí)現(xiàn)了便捷性與智能性。經(jīng)測(cè)試表明本軟件在Windows 2000/XP平臺(tái)下程序運(yùn)行穩(wěn)定且各項(xiàng)功能運(yùn)行得都很正確，基本達(dá)到了預(yù)期的要求。

Automatic generated paper system based on Delphi
Abstract: Use vitrification software of Delphi to empolder an automatic generated paper system, mainly use its various object-oriented application development tools to build a prototype system, and then progress to the demand analysis, through inconstant revision and improvement, until a satisfactory and viable system come into being. The system is well structured and user-friendly, with simplification of data input to the databank, the system has achieved two functions of fully automatic selection of subjects and manual selection of subjects. The development of the background Database includes the establishment, maintenance and front-end application design. The system has a security users download module, user-friendly and convenient functional module browsing interface. The analysis in this paper is based on knowledge of the structural basis of the examination on the knowledge factor is the difficulty, chapters, sections for the main control parameters Zujuan algorithm and the realization of the establishment. The system is used not only to improve the efficiency of the work of teachers, but also achieve a true sense of sexual and convenient wisdom. Testing shows the software platform in Windows 2000/XP stability and operational procedures of the functional operation of a very correctly, the basic met expectations.
