Purpose Complex mechanical 3D computer-aided design (CAD) model embodies rich implicit design knowledge. Through discovering the key function parts and key function module in 3D CAD assembly model in advance, it can promote the designers’ understanding and reuse efficiency of 3D assembly model in design reuse. Design/methodology/approach An approach for discovering key function module in complex mechanical 3D CAD assembly model is proposed. First, assembly network for 3D CAD assembly model is constructed, where the topology structure characteristics of 3D assembly model are analyzed based on complex network centrality. The degree centrality, closeness centrality, betweenness centrality and mutual information of node are used to evaluate the importance of the parts in 3D assembly model. Then, a multi-attribute decision model for part-node importance is established, and the comprehensive evaluation for key function parts in 3D assembly model is accomplished by combining Analytic Hierarchy Process and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS). Subsequently, a community discovery of function module in assembly model-based Clauset–Newman–Moore (CNM)-Centrality is given in details. Finally, 3D CAD assembly model of worm gear reducer is taken as an example to verify the effectiveness and feasibility of proposed method. Findings The key function part in CAD assembly model is evaluated comprehensively considering assembly topology more objectively. In addition, the key function module containing key function part is discovered from CAD assembly model by using CNM-Centrality-based community discovery. Practical implications The approach can be used for discovering important design knowledge from complex CAD assembly model when reusing the assembly model. It can help designers capture and understand the design thinking and intent, improve the reuse efficiency and quality. Originality/value The paper first proposes an approach for discovering key function module in complex mechanical 3D CAD assembly model taking advantage of complex network theory, where the key function part is evaluated using node centrality and TOPSIS, and the key function module is identified based on community discovery.

“…Remark The dynamic behavior of the flexible marine riser is described by a typical E‐B beam. The E‐B beam can be utilized to represent a great number of flexible structures, such as a flexible manipulator, 32 solar panels of a spatial spacecraft, 52 and high‐rise building structures 53,54 . This article provides a detailed control synthesis step and the reported control scheme is available to be applied to the above‐mentioned flexible structures dominated by the E‐B beam.…”

In this article, we investigate the stabilization control problem of a flexible marine riser system with a failed and bounded control action and time‐varying boundary constraints. The considered system is modeled as a distributed parameter system dominated by a partial differential equation. The involved problems are extended to some more general conditions. The saturation and failures of the actuator make the input and output of the actuator a nonlinear relationship, which leads to the normally designed control input invalid. By applying the Nussbaum gain technique, we report a synthetical control method to tackle the input nonlinearity. A piecewise barrier Lyapunov function (BLF) is introduced to reduce the boundary displacement in an asymmetric open set. Compared with the traditional BLFs, the initial boundary displacement is not forced to retain within the given region by integrating a shifting function into the BLF design. In addition, the adaptive method is combined with the hyperbolic tangent function to provide a smooth control solution to the unknown parameters from nonlinear input and external perturbation. Relying on a Lyapunov‐based analysis and a numerical simulation, it is proven that the actuated riser system is uniformly bounded and the boundary displacement always keeps in the limited set even subject to actuator failures and limitations.

“…However, most of his research involves buildings with about 10-20 floors, which is not typical. Song et al proposed an infinite-dimensional system model for describing high-rise building structures with large inertial loads [3]. His model provided some support for the stability of high-rise building construction, but still has limitations in the study of all-round control.…”

The construction of high-rise buildings usually involves many problems. With the increasing population and demand for tall buildings, researchers have also proposed different design approaches for various aspects of tall buildings. The design of traditional construction organization is difficult to cover all systems of high-rise buildings comprehensively and efficiently. Among the high-rise buildings involved, the first important is safety, followed by energy conservation. The high floor and complex structure of high-rise buildings bring hidden dangers to safety, and the large volume brings a burden to energy conservation. In this paper, in order to solve the problems that the system is difficult to fully cover in high-rise buildings and the design of consumables and energy materials, the method of distributed system is adopted. The main aspects of high-rise buildings are studied in an all-round way, and a distributed system model is first constructed in this paper. Then, the lighting, air conditioning, and fire protection systems of high-rise buildings are correspondingly formed under this system. Through the simulation experiment of the B4 building in the business district, it is concluded that the average luminous flux of lighting under the distributed system of this paper is 11385 lm, saving more than 60% of energy. The error of the air-conditioning system is less than 0.2°C, and the energy consumption is saved by 10%. The fire detection window length of the fire protection system exceeds 0.15, which can detect the fire sensitively. In addition, the evacuation pressure of personnel is reduced by more than 20% in emergency situations. The results show that the system establishment of high-rise buildings under the distributed method in this paper can effectively improve the efficiency, save energy consumption, and reduce the pressure of resource utilization. The design of this paper unifies the overall and local control objectives, which can fully meet the needs of comfort and convenience.
