Abstract:To deal with the design of remanufacturing reverse logistics network, considering the uncertainty of the product recovery and consumer market demand, a multi-period remanufacturing reverse logistics network model based on third-party recovery was established in order to maximize the benefits of both the third-party logistics supplier and the manufacturer. The model can be determined for the best price of products that the manufacturer pays for the third-party logistics supplier each period. The numbers of recycling centers and inspection/disassembly centers, and the allocation of the corresponding goods flows in the network can be decided. The uncertainty parameters were denoted by the triangular fuzzy numbers. With fuzzy chance constrained programming methods, the network model in the uncertain environment can be transferred into a certainty equivalent model. The validity of the model was illustrated by a numerical example, and the relationship between the two goals was analyzed by goal programming method.

Meanwhile, to reduce its computation complexity, the convolution operation is replaced by summation for its potential linear relation in the special time. Theoretical analysis and simulated result proves that the proposed algorithm can improve receivers' sensitivity and reduce its computation.

Abstract:HHJ is one of the mostly used core join algorithms for query processing in a database management system. This paper proposes a buffer-optimized hybrid hash join algorithm(OHHJ) by optimizing the bucket buffer to reduce the random I/O in hash join, i.e., to minimize the random I/O by optimizing the bucket buffer size in partition phase. By quantitatively analyzing the relationship between the bucket size, bucket buffer size, available memory size, relation size and random I/O access characteristics of hard disk, we have derived the heuristics for allocating the optimal bucket and bucket buffer sizes. The experimental results demonstrate that OHHJ can effectively reduce random I/O in HHJ during partition phase, and thus enhance the performance of the algorithm.

After image processing, diameter of each log and the number of logs is obtained, and this process is key point of scaling automation for bundled logs. Because the imaging environment of bundled logs is complex, much man-machine interaction is needed while using the existing methods for outline identification of bundled logs.

In the next step, Laplace filter is used to work out the edge in the image, implementing the separation of log outlines. Finally, we achieve outline identification of bundled logs.
