报告摘要

Digital fabrication is growing in adoption within the architecture, engineering, and construction industry. Because digital fabrication often requires a systematic rethinking of the design process, research emphasizes new understanding is needed for digital systems across multiple areas, including technical development, technological systems, organizational contexts, contractual provisions, and business models. To fill better understand the strategies for wider adoption of digital fabrication approach and processes, this guest lecture will explain the how the industry needs and perceived benefits are categorized to drive the success of digital fabrication in construction. This include (1) a multi-aspect mapping of variable correlations under different categories of the industry needs of fabrication information and aspects in design modeling, review, and documentation; and (2) a single-aspect mapping of the correlations regarding the industry needs for various benefits of digital systems to adopt digital fabrication. The consistent identification of the needs and their interdependencies constitute an integral part of knowledge in digital construction management and integration.

报告摘要

Exchange markets are a significant type of market economy, in which each agent holds a budget and certain (divisible) resources available for trading. Most research on equilibrium in exchange economies is based on an environment of completely free competition. However, the orderly operation of markets in reality also relies on effective economic regulatory mechanisms. This paper initiates the study of the mechanism design problem in exchange markets, exploring the potential to establish truthful market rules and mechanisms. This task poses a significant challenge as unlike auctioneers in auction design, the mechanism designer in exchange markets lacks centralized authority to fully control the allocation of resources.

In the paper, we model market mechanism design. The problem is formalized as a two-stage game. In stage 1, agents submit their private information to the manager, who then formulates market trading rules based on the submitted information. In stage 2, agents are free to engage in transactions within these rules, ultimately reaching an equilibrium. We generalize the concept of liquid welfare from classical budget-feasible auctions and use market liquid welfare as a measure to evaluate the performance of the designed mechanism. Moreover, an extra concept called profitability is introduced to assess whether the market is money-making (profitable) or money-losing (unprofitable). Our goal is to design a truthful mechanism for the market manager that achieves an (approximate) optimal welfare while minimizing unprofitability as much as possible. We propose two mechanisms for the problem. The first one guarantees truthfulness and profitability while approaching an approximation ratio of approximately 1∕2 in large markets. The second one is truthful and achieves 1∕2 approximation in general markets but incurs bounded unprofitability. Our aim is for both mechanisms to provide valuable insights into the truthful market design problem.
