摘要

The first essay on improving software development productivity addresses issues related to a new software development approach called pair programming. The remaining two essays in this dissertation focus on economic and operational issues in content distribution networks. Each essay uses methodologies such as integer programming, numerical simulation, and game theory to tackle these Information Systems issues.;Recently there has been considerable interest in pair programming---a novel development approach in which a pair of developers jointly works on the same piece of code. The purpose of the first study is to compare the performance of pair development with that of solo development under two separate objectives---effort minimization and time minimization. In both cases, we develop analytical models to calculate optimal module to developer assignments (for both the pair and solo approaches) so as to minimize the objective being served.;In the second essay, we develop an economic model to investigate the impact peer-to-peer (P2P) networks on the providers of content distribution services (such as Akamai). Our finding is that the eventual impact of a P2P network could either benefit or hurt the profits of a content distribution provider (CDP). Our model considers the incentives of the producer (or content provider, e.g., CNN) together with the incentives of the consumer (who derives some positive utility from consuming the content) to derive the optimal extent of content distribution, with and without the existence of a P2P network.;In the third essay, we present and analyze a simple, structured model of peer-to-peer (P2P) networks to gain insights. The primary objective of this study is to examine whether sharing in P2P networks can result purely from self-interest. Another goal is to understand the conditions under which free-riding can occur. We find that congested external common resources, such an external link through which all traffic enters and leaves the P2P community, play a key role in determining the sharing profile of a P2P community. Finally, free-riding can be shown to occur if the participants are heterogeneous with respect to the resources they possess.
機譯：關(guān)于提高軟件開發(fā)生產(chǎn)率的第一篇文章論述了與一種稱為結(jié)對編程的新軟件開發(fā)方法有關(guān)的問題。本論文的其余兩篇論文集中于內(nèi)容分發(fā)網(wǎng)絡(luò)中的經(jīng)濟和運營問題。每篇文章都使用整數(shù)編程，數(shù)值模擬和博弈論等方法來解決這些信息系統(tǒng)問題。最近，人們對結(jié)對編程產(chǎn)生了濃厚的興趣，這是一種新穎的開發(fā)方法，在該方法中，成對的開發(fā)人員可以共同從事同一工作一段代碼。第一項研究的目的是比較兩個單獨目標（努力最小化和時間最小化）下的結(jié)對發(fā)展和單人發(fā)展的表現(xiàn)。在這兩種情況下，我們都開發(fā)了分析模型，以計算針對開發(fā)人員分配的最佳模塊（針對配對方法和單獨方法），從而最大程度地降低了所服務(wù)的目標。在第二篇文章中，我們開發(fā)了一種經(jīng)濟模型來研究同行的影響-內(nèi)容分發(fā)服務(wù)提供商（例如Akamai）上的對等（P2P）網(wǎng)絡(luò)。我們的發(fā)現(xiàn)是，P2P網(wǎng)絡(luò)的最終影響可能會受益或損害內(nèi)容分發(fā)提供商（CDP）的利潤。我們的模型考慮了生產(chǎn)者（或內(nèi)容提供者，例如CNN）的激勵因素以及消費者（他們從消費內(nèi)容中獲得一些積極效用）的激勵因素，以在存在和不存在以下情況的情況下得出內(nèi)容分配的最佳范圍：在第三篇文章中，我們介紹并分析一個簡單的，結(jié)構(gòu)化的對等（P2P）網(wǎng)絡(luò)模型，以獲取見識。這項研究的主要目的是檢查P2P網(wǎng)絡(luò)中的共享是否可以純粹出于個人利益。另一個目標是了解可能發(fā)生搭便車的條件。我們發(fā)現(xiàn)，擁擠的外部公共資源（例如所有流量進入和離開P2P社區(qū)的外部鏈接）在確定P2P社區(qū)的共享配置文件中起著關(guān)鍵作用。最后，如果參與者在其擁有的資源方面是異類的，則可以表明發(fā)生了搭便車事件。
