Mechanism design of reverse auction on concession period and generalized quality for PPP projects

Xianjia WANG, Shiwei WU

Frontiers of Engineering Management 2017, Volume 4, Issue 2, Pages 156-170 doi: 10.15302/J-FEM-2017016

Abstract: Thus, the multidimensional reverse auction model of a PPP project can be replaced by a two-dimensionaldirect mechanism based on the concession period and the generalized quality.Moreover, two feasible multidimensional reverse auctions for implementing such a direct mechanism: Adjustingthe scoring function and establishing a special reverse auction rule are built.In such a direct mechanism, the investment and financial pressure of the public sector can be reduced

Toward resilient cloud warehousing via a blockchain-enabled auction approach

Frontiers of Engineering Management Pages 20-38 doi: 10.1007/s42524-022-0224-2

Abstract: Accordingly, a floating mechanism can be considered to introduce more flexible billing.A one-sided Vickrey–Clarke–Groves (O-VCG) auction mechanism model is designed as the underlying floatingbilling mechanism to reflect the real-time market value of fine-grained CWS resources.By analyzing the performance of the O-VCG auction and comparing it with that of the fixed-rate billingmodel, the proposed mechanism has more advantages.

Theory and method of mechanism system design

Huijun ZOU, Qinghua LIANG, Qing ZHANG

Frontiers of Mechanical Engineering 2010, Volume 5, Issue 4, Pages 399-411 doi: 10.1007/s11465-010-0116-8

Abstract: Conceptual design is the most critical and creative phase of design. Recently, increasing attention has been directed to supporting conceptual-level computer aided creative design and its theories and methodologies. Specifically, for conceptual design of mechanical products, this paper presents a novel function solving model for mechanical product design and highlights the importance of systematic synthesis to achieve creative design. Then it builds a framework as a function-effect-process-action- mechanisms (FEPAM) mapping process, which enables creative design on the basis of conceiving different action schemes. After that, several key points are elaborated including 1) representing and decomposition methods of functions and motion behaviors; 2) action scheme representing method based on network plan techniques; and 3) variation and creation methods based on action scheme transformations.

Optimal design of a linkage–cam mechanism-based redundantly actuated parallel manipulator

Frontiers of Mechanical Engineering 2021, Volume 16, Issue 3, Pages 451-467 doi: 10.1007/s11465-021-0634-6

Abstract: A redundantly actuated parallel manipulator (RAPM) with mixed translational and rotational degrees of freedom (DOFs) is challenged for its dimensionally homogeneous Jacobian modeling and optimal design of architecture. In this paper, a means to achieve redundant actuation by adding kinematic constraints is introduced, which reduces the DOFs of the end-effector (EE). A generic dimensionally homogeneous Jacobian is developed for this type of RAPMs, which maps the generalized velocities of three points on the EE to the joint velocities. A new optimization algorithm derived from this dimensionally homogeneous Jacobian is proposed for the optimal design of this type of RAPMs. As an example, this paper presents a spatial RAPM involving linkages and cam mechanisms. This RAPM has 4 DOFs and 6 translational actuations. The linkage lengths and the position of the universal joints of the RAPM are optimized based on the dimensionally homogeneous Jacobian.
