New Formulation for an Economic Order Quantity Distribution Policy in Vendor-Managed Inventory Routing Problems
Authors: Guimarães Thiago , Scarpin Cassius Tadeu , Arns Steiner Maria Teresinha
Published: June 2014

In vendor managed inventory systems, logistics decisions are centralized at the vendor, allowing inventory storage and transportation costs to be reduced simultaneously. Operation of such systems requires the solution of a complex combinatorial optimization problem, known as the Inventory Routing Problem (IRP), which involves managing client inventory and determining the frequency and size of product deliveries as well as the route taken by the vehicle over a given planning horizon. We present a new formulation based on an economic order quantity distribution policy for the multivehicle inventory routing problem (MIRP). A mathematical programming model with additional practical constraints was used for the MIRP. A new heuristic approach that breaks the MIRP down into the following two sub-problems was also proposed: one dealing with the scheduling of deliveries and the formation of delivery clusters over the planning horizon, and the second sub-problem, which builds the routes for the delivery clusters using classic route construction heuristics and a procedure for intra-route improvements. Adjustments between routes are performed with the aid of a new large neighborhood search (LNS) strategy. Small, medium-sized and large scenarios with different storage and transportation costs were generated using parameters based on data from the literature. Extensive computational tests were carried out to determine the effectiveness of the proposed distribution policy and the heuristic used.

Sentiment Information to Vector, a more Automatic Approach for Sentiment Analysis
Authors: Du Lin , Xu Wei Ran , Liu Ping Yang
Published: June 2014

As sentence level sentiment analysis having been studied extensively, it has been proven that the syntactic structure of a sentence usually holds important information for sentiment analysis, especially for handling polarity reversal. However, the previous attempts of adopting such structural information mainly focus on making certain predefined rules which requires large linguistic expertise of the rule-maker,and the procedure itself is often manually labored and time consuming. To solve this problem, in this paper we propose a novel simple vector model to represent a sentence’s syntactic structure and its prior sentiment information uniformly and rapidly. Experiment results show that our proposed approach performs well in COAE 2013 dataset, and could also be used for machine learning algorithms to extract more distinguish features automatically.

Authors: Yan Shou Gang , Xu Qing Tao
Published: June 2014

Considering each interdune lowland as a self-contained unit, we investigated species composition of 15 interdune lowlands in stabilized and active dunes, respectively, and identified the relationship of species richness and lowland area. The results showed that 1) with the enlargement of lowland area, the overall species richness of interdune lowlands in stabilized and active dunes increased logarithmically. When the area was the same, richness of stabilized dunes was more than that of active dunes. 2) with the increasing of lowland area in stabilized and active dunes, psammophytes richness relative to the overall species richness decreased logarithmically. When the area was the same, the percentage in lowlands of active dunes was more than that of stabilized dunes. Therefore, We concluded that dune stabilization, on one hand, raises species richness and on the other, leads to the loss of endemic or rare psammophytes in interdune lowlands.

The mechanical design of computerized glove machine was traditional. It was not only lack of theoretical analysis of key institutions, but running stability needed to be improved. We analyzed the impact of the needle and cams which was based on the computerized glove machine’s knitting theory and key process points. On the basis of SolidWorks, 3-D model of computerized glove machine’s knitting element was created; We imported the 3-D model to ANSYS/LS-DYNA system and realized the motion simulation of needle and cams. As a result, we got the curves of needle’s displacement, velocity and acceleration. According to the simulation parameters of needle’s movement, the knitting element was optimized design. The result reveals that acceleration reaches a maximum of 0.63×105m/s2 when knitting time is 0.052ms. It reduces nearly 16% compare to the result before design optimization of knitting element. The smooth of computerized glove machine is being improved significantly.

Published: June 2014

Since the work conditions of the crankshaft are complicated and the crankshaft interfaces are very weak, strength analysis of crankshaft interfaces is very important. Three dimensional finite element model of the crankshaft is built for strength analysis of the crankshaft interfaces. The crankshaft has three interfaces. During the analysis, contact problem is taken into account. The results show that the maximal stress of the crankshaft is 535MPa, which is less than the yield limit of 1Cr11Ni2W2MoV steel (993MPa). Therefore, the crankshaft interfaces can not be broken during the work of caterpillar tractor.

The escapement mechanism in a mechanical watch movement plays a critical role. Its purpose is to maintain and count the oscillations of the balance wheel. The timekeeping accuracy is therefore regulated. The motion of the escapement mechanism is highly complicated and no in-depth study on its kinematics has been done by now. This paper investigates the kinematics of the Swiss lever escapement which is used in almost all mechanical watches. One half cycle of the motion is described in different phases. Mathematical models for each key component are developed. Simulation result shows that the model is precise in describing and predicting the motion of the escapement. This method is essential for improving and optimizing the design.
