Journal of System Simulation
Abstract: Email is favored by people and has become one of the most universal information communication methods, inspired by its convenience and low cost. However, E-mail has also been abused by malicious people. As a result, Internet has been polluted by spam. Spam not only wastes bandwidth resource, disrupting people's normal life and work, but also influences routine application of mail servers and poses a serious threat to Internet security. Decision tree algorithm was utilized to train extracted mail head feature information to construct a decision tree, which could be further used to filter spam. Variable precision rough set model …

Increase in the frequency of disruptions in the recent times and their impact have increased the attention in supply chain disruption management research. The objective of this paper is to understand as to how a disruption might affect the supply chain network - depending upon the network structure, the node that is disrupted, the disruption in production capacity of the disrupted node and the period of the disruption - via decision trees. To this end, we first developed a 5-tier agent-based supply chain model and then simulated it for various what-if disruptive scenarios for 3 different network structures (80 trials …
