A Logic-Based, Value-Oriented Science of Design

摘要维吉尼亚大学主校区建筑决策定义了设计发展的搜索空间。架构承诺对经济和技术成功具有决定性的影响，但我们缺乏架构和此类结果之间的关键关系的有效说明。鲍德温和克拉克建议从设计规则的角度来解释建筑的本质，并从实物期权的角度来解释建筑的经济价值。Sullivan对设计中灵活性的价值开发了基于选项的帐户，并测试了Baldwin和Clark的模型解释信息隐藏和面向方面设计的能力。一个主要的悬而未决的问题仍然是：这种方法不仅能描述并支持复杂的、软件密集型系统的开发吗？这项研究将进行一项实验，以检验它可以做到这一假设。如果成功，这项工作将在设计决策、设计规则、对设计决策的依赖关系以及依赖结构中的模块化方面证明对复杂体系结构建模的支持；并说明系统设计中的关键价值来源，通过其演变和被利用来为用户创造价值的方式来判断。一个需要解决的理论问题是对实物期权估值模型的西格玛参数进行合理估计的可能性。

Abstract 0438898Kevin SullivanUniversity of Virginia Main CampusArchitectural decisions define search spaces within which designs evolve. Architectural commitments decisively influence economic and technical success, yet we lack a validated account of key relationships between architectures and such outcomes. Baldwin and Clark have proposed an account of the nature of architecture in terms of design rules, and of its economic value in terms of real options. Sullivan has developed options-based accounts of the value of flexibility in design and tested the ability of Baldwin and Clark's models to explain information hiding and aspect-oriented design. A major open question remains: Can this approach not only describe but support development of complex, software-intensive systems? This research will perform one experiment to test the hypothesis that it can. If successful, the work will demonstrate support for the modeling of complex architectures in terms of design decisions, design rules,dependence relations on design decisions, and modularity in the dependence structure; and account for key sources of value in the system design, judged by the ways it evolved and was exploited to create value for users. A theoretical issue to be addressed is the possibility of defensible estimates of the sigma parameter of the real options valuation model.
