In order to solve the problem of cross-border e-business export logistics, in\nthis paper, a new mode of cross-border e-business export logistics based on\nvalue chain is offered. First, the paper summed up many present modes of\nexport logistics based on cross-border e-business, such as International postal\npacket, International express. And they all cannot satisfy the demands of\ncross-border e-business. Then, the paper cites the principle of the value chain\nand discusses how to apply value chain into cross-border e-business export\nlogistics. The last part of this paper provides some suggestions....
In order to coordinate time-varying price supply chain with inequity-averse retailers, this paper proposes a cooperative system\ndecision model based on buy-back contract. The model concentratedly takes the market demand, manufacturersâ?? order response\ntime, retailersâ?? inequity aversion, and time-varying price into consideration. Through sensitivity analysis of model parameters,\nthe influence of inequity aversion characteristics of retailers on contract parameters is analyzed by a numerical example. The\nresult reveals that the cooperative system based on buy-back contract can coordinate such supply chains. And it shows that when\nthe retailer has disadvantageous inequity aversion, the buy-back contract is beneficial to the manufacturer; when the retailer has\nadvantageous inequity aversion, the buy-back contract is beneficial to the retailer....
In the Big Data era, Big Data Information (BDI) has been used in the book supply industry. Data Company as an important BDI\nsupplier should be included in a book supply chain. Thus, to explore the investment decision-making problems of BDI and its\neffects on the coordination and pricing rules of book supply chain, a three-stage book supply chain with one book publisher, one\nretailer, and one Data Company was chosen. Meanwhile, four benefit models about BDI investment were proposed and analyzed\nin the environments of symmetry information and asymmetric information. A revenue sharing contract was used to achieve book\nsupply chain coordination. Findings: whether the book publisher and the retailer were suitable to invest in BDI, it was influenced\nby the cost improvement coefficient. With the ascent of the cost improvement coefficient, benefits of supply chain members will\nreduce, and, in different investment models, their prices show different change trends with the cost improvement coefficient....
It is extremely important to model the empirical distributions of dry bulk\nshipping returns accurately in estimating risk measures. Based on several\ncommonly used distributions and alternative distributions, this paper establishes\nnine different risk models to forecast the Value-at-Risk (VaR) of dry\nbulk shipping markets. Several backtests are explored to compare the accuracy\nof VaR forecasting. The empirical results indicate the risk models based on\ncommonly used distributions have relatively poor performance, while the alternative\ndistributions, i.e. Skewed Student-T (SST) distribution, Skewed Generalized\nError Distribution (SGED), and Hyperbolic distribution (HYP)\nproduce more accurate VaR measurement. The empirical results suggest risk\nmanagers further consider more flexible empirical distributions when managing\nextreme risks in dry bulk shipping markets....
The development of e-commerce has prompted traditional enterprises to\nopen up online channels and form a dual-channel sales model. The increase\nin the number of channels has led to an increase in the number of orders, so\nhow to properly and effectively match the order with the inventory will test\nthe operational capabilities of the enterprise. Based on this practical problem,\nthis thesis considers a two-echelon distribution system with online and offline\ndual-channel sales, which consists of one group node (G) and multiple distribution\nnodes (D). When online orders are not fully satisfied, we propose an\noperation mechanism of transporting inventory to online orders through offline\ninventory. An optimal decision model is constructed by using the Analysis\nTarget Cascading (ATC). Finally, the model is simulated and analyzed\nwith a specific case. The results show that the ATC method and the transshipment\nmechanism are effective....
