The issues and challenges involved in controlling the collaborative changes in a Building Information Modeling (BIM) data repository, in a multi-model collaboration environment, are discussed. It is suggested that managing iterative changes in BIMs is a database problem, exacerbated by the long transaction times needed to support collaborative design progression. This is yet to be resolved in the construction industry and better solutions are needed to support the underlying workflows and computing operations for seamless collaboration on BIMs. With this in mind, this paper proposes the use of the structural and semantic characteristics of BIM objects as a mechanism for tracking changes across co-developed solutions. The creation of object signatures, using hash codes derived from their characteristics, provides a potential mechanism for object comparison and effective change recognition and management.

技术发展现状——为什么施工中会出现返工?返工会造成什么后果?怎样才能减少返工? Review

已有大量研究对施工中的返工问题进行了研究,但解决返工问题的成效有限,仍然困扰着施工进程,这对项目的绩效产生不利影响。几乎所有返工研究都侧重于确定其近端或根本原因,因此忽略了导致返工的条件。本文借鉴了之前的实证研究,对这一空白进行了研究,以提供一个急需的理论框架,从而更好地理解返工原因、返工后果以及如何在施工期间减少返工。从审查中得出的理论框架使施工组织认识到,减少返工应首先建立一套差错管理文化,包括真正的领导力、心理安全、差错管理导向和复原力。本研究认为,一旦在施工组织及其项目中建立了差错管理文化,施工组织就能更好地认识用于解决返工问题的方法、工具和技术的益处,如精益生产®和建筑信息模型。本文还为未来研究提供了方向,并确定了对实践的意义,以便能够在施工中减少返工。

本文提出了一种基于近似分析方法的环缝天线罩带内和带外微波无线功率传输特性分析方法。本文的主要贡献是对环形天线罩的近似分析,推导了E平面和H平面扫描时天线罩表面入射场的统一表达式,并将环形天线罩近似分为30段直条。求解相应的60 × 60线性方程得到了沿环形带的电流分布。沿着互补槽环的磁电流是通过对偶获得的。得益于电流分布的全解析格式,使用Munk方案有效地计算了微波无线功率传输特性。以环缝双层对称混合天线罩为例,验证了该方法的准确性和有效性。HFSS和所提出的方法的CPU计算时间分别约为690 s和2.82 s。

Knowledge representation is the core of artificial intelligence research. Knowledge representation methods include predicate logic, semantic network, computer programming language, database, mathematical model, graphics language, natural language, etc. To establish the intrinsic link between various knowledge representation methods, a unified knowledge representation model is necessary. According to ontology, system theory, and control theory, a standard model of knowledge representation that reflects the change of the objective world is proposed. The model is composed of input, processing, and output. This knowledge representation method is not a contradiction to the traditional knowledge representation method. It can express knowledge in terms of multivariate and multidimensional. It can also express process knowledge, and at the same time, it has a strong ability to solve problems. In addition, the standard model of knowledge representation provides a way to solve problems of non-precision and inconsistent knowledge.
