An Information Flow Framework to Model, Automate, and Optimize Value Delivery in AEC

到2022年，加拿大建筑业预计将达到2676亿美元。项目的成功可以通过其实现多个利益相关者（即客户、设计师、建设者、公共机构、运营商等）的价值的能力来衡量。价值可以理解为满足利益相关者在功能、时间、成本、质量、可持续性、可服务性、美学等方面的需求。然而，建筑业受到各种问题的困扰，包括信息流不足，这些问题成倍增加并向下游传递到建筑业。例如，大约50%的设计时间花在非增值任务上，比如返工。随后，项目无法实现预期的价值，留下了不满意的干系人。因此，加拿大建筑业迫切需要对利益相关者之间的动态互动和跨项目阶段的价值演变进行建模，并开发创新的方法，其中自动化和精益方法可以用于指导专业人员、组织和政策，以更低的成本、时间、浪费和返工交付项目。本研究旨在设计一个量化框架来理解、测量、建模和优化使用精益原则在设计和施工中的价值交付。具体研究步骤包括：(1)在整个项目阶段对产品和过程价值的演变进行建模；(2)调查影响价值的因素，如协作、整合交付、谈判、即兴等；(3)研究利益相关者网络内部不同学科之间的互动与信息交换；(4)开发新的过程绩效指标和行业友好的自动化工具来衡量价值产生；(5)通过采用精益施工技术和先进的BIM功能来优化价值交付。一旦全面实施，这一创新项目有望显著提高加拿大建筑业的价值创造。预计减少20%的隐性浪费和潜在价值可以减少数百万美元的项目成本，带来显着的时间收益，减少返工，并提高加拿大项目的客户满意度。在实际项目中测试的综合框架和现实模型的生产将为加拿大建筑业提供先进的自动化工具，以评估和监控整个设计和施工过程中的价值交付和沟通。提供基于证据的结果来展示价值驱动项目的好处，将鼓励加拿大的利益相关者和政策制定者改变传统的方式，以更低的过程浪费实现更高的价值。除了对HQP进行先进计算方法的培训外，该项目还将为加拿大提供研究和实践机会，使其有机会成为世界范围内技术创新和价值项目交付政策制定的先锋。

The Canadian construction industry sector is expected to reach US$ 267.6 billion by 2022. Project success can be measured by its ability to fulfill the realized value of multiple stakeholders - namely the client, designers, builders, public agencies, operators, and others. Value can be understood as fulfilling stakeholders' needs in terms of functionality, time, cost, quality, sustainability, serviceability, aesthetics, etc. However, the construction industry is plagued with various issues, including information flow deficiencies, that multiply and pass downstream into construction. For instance, about 50% of design time is spent on non-value-adding tasks, such as rework. Subsequently, projects fail to achieve their desired value, leaving behind unsatisfied stakeholders. Therefore, there is a pressing need in the Canadian Construction Industry to model the dynamic interactions between stakeholders and the evolution of value across project phases, and to develop innovative means where automation and lean methods can be used in guiding professionals, organizations, and policy to deliver projects at lower cost, time, waste, and rework. This research aims to design a quantitative framework to understand, measure, model, and optimize value delivery in design and construction using lean principles. The specific research steps include: (1) modeling the evolution of product and process value throughout project phases; (2) investigating factors impacting value such as collaboration, integrated delivery, negotiation, and improvisation; (3) studying interactions and information exchanges between different disciplines of within the stakeholder network; (4) developing new process performance metrics and an industry-friendly automated tools to measure value generation; and (5) optimizing value delivery by employing lean construction techniques and advanced BIM capabilities. When fully implemented, this innovative project is expected to significantly improve value generation in Canadian Construction Industry. An expected 20% reduction in hidden waste and latent value can reduce millions of dollars in project cost, lead to significant time gains, decrease rework, and increase customer satisfaction on Canadian projects. The production of a comprehensive framework and realistic models that are tested on real projects will provide the Canadian Construction Industry with advanced automation tools to assess and monitor the delivery and communication of value throughout design and construction. Providing evidence-based results to showcase the benefits of value-driven projects will encourage Canadian stakeholders and policy makers to transform traditional ways for higher value realization at lower process waste. In addition to training HQP on advanced computational methodologies, the project will provide research and practice in Canada with the opportunity to be world-wide vanguards of technological innovations and policy making in value project delivery.
