什么是數(shù)學(xué)模型？他們是如何被開發(fā)的？我們應(yīng)該多么信任它們：我們能否對(duì)他們的預(yù)測(cè)保持信心，又知道何時(shí)該付諸行動(dòng)？這些問題，數(shù)學(xué)建模從業(yè)者經(jīng)常討論，同時(shí)也引起了公民和政策制定者的關(guān)注。我們的現(xiàn)代社會(huì)需要可依賴的模型，不僅能加深對(duì)情境的理解，還能指導(dǎo)政策決策。這本數(shù)學(xué)建模入門課程是為攻讀應(yīng)用數(shù)學(xué)、生命科學(xué)或工程方向的大學(xué)四年級(jí)學(xué)生開發(fā)的。課程基于微積分、線性代數(shù)和微分方程的知識(shí)，涵蓋數(shù)學(xué)建模中至關(guān)重要的基本技術(shù)和思維過(guò)程
