Abstract:

To solve the problem that stock and increment sharing of container can not be effectively implemented, a container sharing model based on blockchain principle was proposed. Firstly, the operation mechanism of blockchain based container sharing mode was elaborated. Secondly, the changes of container transportation process with the influence of this mode were analyzed. Thirdly, based on Petri net theory, Colored Timed Petri Net (CTPN) models of traditional mode and blockchain based container sharing mode were established respectively by CPN Tools. Finally, the simulation of the models were carried out with four indicators compared and analyzed under different modes. The four indicators were the time from receipt of orders to picking up of empty containers, the ratio of empty driving time in the road, the order loss rate and the proportion of unloaded containers. The experimental results show that compared with under the traditional mode, under the blockchain based container sharing mode, the shipper's picking up time is shortened, the empty driving proportion reduces by 5.28% while there is no longer any order lost due to the mismatch between the shipping time and the order time window, and the proportion of unloaded containers is reduced by 6.99%. The simulation results show that the blockchain based container sharing mode can not only make up for the shortcomings of stock and increment sharing of container in the traditional ways, but also optimize the container transportation process. It is an effective way to reduce costs and increase efficiency in container transportation industry.

摘要:

针对集装箱存量共享与增量共享均不能有效实施的问题,提出基于区块链原理的集装箱共享模式。首先,阐述基于区块链原理的集装箱共享模式的运作机制;其次,分析在该模式的作用下,集装箱运输流程发生的变化;然后以Petri网理论为基础,使用CPN Tools分别建立传统模式与基于区块链集装箱共享模式下的集装箱运输流程的赋时着色Petri网(CPTN)模型;最后,对模型进行仿真实验,选取不同模式下接收订单到提取空箱装货的时间、路运段空车行驶时间比例、订单损失率、作漏装的集装箱比例这四项指标对比分析。实验结果显示,与传统模式下相比,基于区块链的集装箱共享模式下,发货人提箱时间缩短,集卡空车行驶比例减小5.28%,不再出现因船期与订单时间窗不匹配而损失的订单,作漏装的集装箱比例减小6.99%。通过仿真实验结果可知,基于区块链原理的集装箱共享模式不仅能够弥补集装箱存量共享与增量共享中存在的不足,而且对集装箱运输流程起到优化作用,是集装箱运输行业实现降本增效的一种有效途径。
