    在共享经济时代,物流服务行业建立稳定的联盟至关重要。因此,在物流企业联盟内部,如何确保公平的收益分配成为一大挑战。然而,由于联盟存在信息不完备的情况,一些传统的合作博弈单值解,例如Shapley值,可能并不适用于该问题,这些解法更适用于联盟的总体收益和各博弈者的参与水平都能够被准确估计的情形。研究了信息不完备的物流企业联盟的收益分配问题,并提出了一种相关的收益分配模型。为了证明所提出模型的适用性,进行了一个案例研究。结果表明,模糊Shapley值能合理地提升多方合作后的各方收益,有效地分配物流企业联盟的收益。

    To address the issues of low efficiency, excessive redundancy, and the inability to dynamically avoid obstacles in indoor robot path planning when using the A* algorithm, this paper proposes a fusion algorithm that combines an optimized A* algorithm with the dynamic window approach. The proposed algorithm enhances the heuristic function by incorporating the distance from the parent node to the target node. It quantifies the obstacle information to dynamically adjust the weights of the heuristic function using an obstacle rate function. Additionally, it introduces a cost for turning to reduce unnecessary turns in the path and designs a strategy to remove redundant points, ensuring a globally optimal static path. It incorporates the offside angle, flexibly selects the key nodes of the A* algorithm as local target points within the dynamic window to avoid the path getting trapped in local optima. The experimental results demonstrate that the improved fusion algorithm enhances the search efficiency, reduces the path length, resolves the issue of the dynamic window approach being trapped in local optima and enables the real-time obstacle avoidance.

    Predictive maintenance reduces unnecessary maintenance by timely diagnosing or predicting the state of the device, and deep learning methods can realize the above process by mapping the device feature parameters to the state of the device. The wide variety of equipment and the predictive maintenance of equipment in multiple working conditions also place higher demands for deep learning methods, and a reasonable selection of deep learning methods thus becomes crucial. Therefore, the development process and the latest application of deep learning in predictive maintenance are discussed in this paper, with a view to further promote the application of predictive maintenance in more devices, to improve the accuracy of deep learning methods in predictive maintenance applications, and to envision the future development of deep learning methods in predictive maintenance.

    The machining quality of electric spindles critically determines precision, efficiency, and stability in precision manufacturing. However, the machining process faces challenges due to diverse product types, multiple operating conditions and scarce target-condition data, making consistent quality of electric spindle difficult to guarantee. To address this, this paper proposes a transfer-learning-based method for multi-operating-condition quality prediction. The method first extracts spindle time-series signals and employs the Synthetic Minority Over-sampling Technique to balance historical and target-condition data distributions. Subsequently, constructs a two-stage regression model, TrAdaboost.R2, and leverages knowledge transfer to predict spindle quality under target conditions. Finally, the proposed method is validated with electric spindle data, demonstrating its superior prediction performance. This approach provides an effective framework for the precise quality prediction of electric spindles across varying operating conditions.

    By analyzing the existing gangue sorting manipulator claw and its use, it is concluded that the existing claw has a large weight, is susceptive to wear and tear as well as higher cost of the overall replacement. A method is hence adopted to install replaceable wear-resistant shims and to select lighter quality materials for improvement. The finger force analysis is made before and after the improvement through the Ansys Workbench, and the improved finger effect proves to be better, verifying the feasibility of the installation of replaceable wear-resistant shims, while determining the replaceable wear-resistant shims material being 20CrMnSi, and finger base material being TC4. The fatigue life analysis is made for the finger before and after the improvement using fatigue analysis tools, and the conclusion is drawn that the fatigue life of improved finger matrix is longer, and the replaceable wear-resistant shims begin to fail after being used 4.3794×105 times, and are therefore needed to be replaced after about two months of use.
