中  文  摘  要

設(shè)計(jì)在線考試系統(tǒng)的目的在于減輕教師的工作負(fù)擔(dān)，實(shí)現(xiàn)考試的公平、公正，提高考試效率，并且通過(guò)對(duì)學(xué)生測(cè)驗(yàn)結(jié)果的分析，可以為教與學(xué)提供反饋信息，促使教師改進(jìn)教學(xué)，促進(jìn)學(xué)生學(xué)習(xí)。教師建立試題庫(kù)的過(guò)程，既是一個(gè)收集整理的過(guò)程，也是一個(gè)積累教學(xué)經(jīng)驗(yàn)的過(guò)程。
本論文的中心環(huán)節(jié)為B/S架構(gòu)和遺傳算法組卷。應(yīng)用B/S模式架構(gòu)，應(yīng)用系統(tǒng)的中心功能集中到服務(wù)器上，簡(jiǎn)化了系統(tǒng)的開(kāi)發(fā)、維護(hù)、更新和使用，客戶端只需安裝一個(gè)瀏覽器軟件，即可進(jìn)行考試，不需要安裝用戶界面應(yīng)用程序，真正實(shí)現(xiàn)了“瘦客戶”， 系統(tǒng)的擴(kuò)展也非常容易，只需對(duì)服務(wù)器的應(yīng)用程序擴(kuò)展，實(shí)現(xiàn)客戶端的同步更新。優(yōu)化遺傳算法智能組卷，避免隨機(jī)組卷生成隨意性試題的問(wèn)題和陷入無(wú)限循環(huán)的死區(qū)，使組卷進(jìn)一步智能化、科學(xué)化，提高了搜索效率，同時(shí)根據(jù)試題的難度對(duì)試題進(jìn)行智能組卷，以章節(jié)的分值占試卷總分值的比例作為知識(shí)點(diǎn)搜索條件,使試題定位更加合理準(zhǔn)確。
該系統(tǒng)實(shí)現(xiàn)考試的網(wǎng)絡(luò)化、無(wú)紙化、智能化，適用于Internet，前端考試應(yīng)用系統(tǒng)和后端數(shù)據(jù)庫(kù)管理系統(tǒng)均采用 B/S 模式，而且對(duì)服務(wù)器的配置要求非常低，客戶端不用任何設(shè)置。通過(guò)后臺(tái)管理功能，教師建立題庫(kù)和考生信息庫(kù)；前臺(tái)應(yīng)用系統(tǒng)實(shí)現(xiàn)，到時(shí)間就自動(dòng)交卷，然后自動(dòng)判卷，公正、安全、方便地完成考試。前臺(tái)內(nèi)容包括：登陸、開(kāi)始考試、確認(rèn)交卷、評(píng)分。后臺(tái)內(nèi)容包括：考生信息管理、題庫(kù)管理，遺傳算法組卷、成績(jī)分析。

關(guān)鍵詞：在線考試；題庫(kù)管理；遺傳算法組卷；B/S架構(gòu)

ABSTRACT
The purpose of online examination system designed alleviate the workload of teachers, in order to achieve a fair test, just. Through analysis of test results to students,it can provide feedback for teaching and learning, encourage teachers to improve teaching, promote student learning. Teachers establish exam bank,it is a collection of sorting process and a process of accumulation of teaching experience.
The central part of this paper is B / S structure and genetic algorithm. By B/S structure, System at the core of focus to the server, Simplifies system development, maintenance and use. Clients only need to install a browser software, no need to install the user interface application, so that "thin client", Expansion of the system is very easy. Breakthrough random algorithm test paper, test paper can achieve the genetic algorithm, to avoid the random search is easy to produce an infinite loop problems and improve the search efficiency, but also with the difficulty of the questions were questions Forecasting and Endowing, knowledge point total score total scores of papers percentage point of search terms as knowledge, make more reasonable and accurate positioning questions.
This system tests the network, paperless, automated, can be used to INTERNET and LAN, front-end applications and back-end management system were adopted B / S model, but the server configuration requirements are very low, the client do not have any settings. By background management functions , teachers and candidates can establish item bank database; front application system to automatically carry out an assignment on time, and then automatic grading, fair, safe, easy to complete the examination. Front cover: login, start test, an assignment confirmed, rates,. Background includes: candidate information management, paper management, genetic algorithm test paper, performance analysis.

Keywords: Online; Paper management; Genetic algorithm test paper
