LINGO優(yōu)化軟件簡(jiǎn)介lingo是用來(lái)求解線性和非線性優(yōu)化問(wèn)題的簡(jiǎn)易工具。LINGO內(nèi)置了一種建立最優(yōu)化模型的語(yǔ)言，可以簡(jiǎn)便地表達(dá)大規(guī)模問(wèn)題，利用LINGO高效的求解器可快速求解并分析結(jié)果。Lingo 是使建立和求解線性、非線性和整數(shù)最佳化模型更快更簡(jiǎn)單更有效率的綜合工具。Lingo 提供強(qiáng)大的語(yǔ)言和快速的求解引擎來(lái)闡述和求解最佳化模型。Lingo 實(shí)際上還是最優(yōu)化問(wèn)題的一種建模語(yǔ)言,包括許多常用的函數(shù)可供使用者建立優(yōu)化模型時(shí)調(diào)用,并提供與其他數(shù)據(jù)文件（如文本文件、Excel電子表格文件、數(shù)據(jù)庫(kù)文件等）的接口,易于方便地輸入、求解和分析大規(guī)模最優(yōu)化問(wèn)題。 實(shí)驗(yàn)總結(jié)通過(guò)此次運(yùn)籌學(xué)實(shí)驗(yàn)，我對(duì)于運(yùn)籌學(xué)的學(xué)習(xí)方面有極大的收獲,在這一周的實(shí)驗(yàn)過(guò)程中，不僅對(duì)運(yùn)籌學(xué)的有關(guān)知識(shí)有了進(jìn)一步的掌握，而且學(xué)會(huì)了通過(guò)建立模型解決實(shí)際生活中的相關(guān)問(wèn)題.在對(duì)問(wèn)題的分析、建模、求解過(guò)程中鍛煉了我們的思考能力，同時(shí)提高了分析、解決問(wèn)題的能力，也更加了解和熟悉了Ｅxcel規(guī)劃求解的強(qiáng)大功能，提高了我們的計(jì)算機(jī)應(yīng)用水平。 同時(shí)，我在此次試驗(yàn)中也存在一些不可避免的問(wèn)題和不足。例如，在進(jìn)行線性規(guī)劃實(shí)驗(yàn)時(shí),由于對(duì)空格鍵的作用和*的忽視,曾出現(xiàn)過(guò)多次錯(cuò)誤提示,而沒(méi)能運(yùn)行出結(jié)果,最終經(jīng)過(guò)對(duì)實(shí)驗(yàn)資料的詳細(xì)閱讀及多次的反復(fù)試驗(yàn)得到了實(shí)驗(yàn)結(jié)果；在列約束條件時(shí)粗心大意出現(xiàn)差錯(cuò)，導(dǎo)致最終結(jié)果的錯(cuò)誤從而影響實(shí)際問(wèn)題解決的效果，因此，我們?cè)谶@方面應(yīng)該加以注意和改正，在進(jìn)行建模求解時(shí)細(xì)心耐心。在進(jìn)行實(shí)驗(yàn)的過(guò)程中,使得我對(duì)matlab的操作更加熟練。學(xué)會(huì)了操作懂得了一些運(yùn)籌學(xué)的運(yùn)用，結(jié)合實(shí)際生活解決問(wèn)題。所以，通過(guò)這次實(shí)驗(yàn)，不僅對(duì)運(yùn)籌學(xué)的有關(guān)知識(shí)有了進(jìn)一步的掌握，同事對(duì)在自己的計(jì)算機(jī)操作水準(zhǔn)也有了很大的提高。這次實(shí)驗(yàn)讓我懂得了運(yùn)籌學(xué)在電腦的應(yīng)用，讓我對(duì)運(yùn)輸與數(shù)學(xué)相結(jié)合的應(yīng)用理解更深了。在這一系列的操作過(guò)程中，不僅可以體會(huì)到數(shù)學(xué)問(wèn)題求解的嚴(yán)謹(jǐn)和規(guī)范，同時(shí)也有對(duì)運(yùn)籌學(xué)解決問(wèn)題的喜悅。 最后，課程的學(xué)習(xí)很快過(guò)去，但它對(duì)我們掌握運(yùn)籌學(xué)建模問(wèn)題的要求卻并沒(méi)有隨課程的結(jié)束而結(jié)束。此次實(shí)驗(yàn)課的學(xué)習(xí)提高了我們的技能，為以后的學(xué)習(xí)和工作打下了堅(jiān)實(shí)的基礎(chǔ)。簽字： 評(píng)分： ；應(yīng)用理學(xué)院 數(shù)學(xué)與應(yīng)用數(shù)學(xué)專業(yè)2015年 12 月 18 日27
