Complex Project Schedule Risk Simulation Based on Multi-agent

Haolin Wen, Tao Hu, Gongda Yan
In order to solve the problems of complex projects schedule risk assessment, a project schedule risk assessment model based on the multi-agent was established by the Anylogic software in this paper. In this model, a "process" agent, a "process flow", a "risk factor" and a "control" agent were designed...

The Effect of Behavior Conformity on Prisoner's Dilemma Game

Zidong Chai, Yanbo Zhang, Xinyu Zhang, Xiaobo Liu
Explaining the evolution of cooperative behavior is one of the most important and interesting problems in a myriad of disciplines. Game players on complex networks usually change their strategies by copying special rules. In this research, we combine the prisoner's dilemma game player's behavior conformity...

CT Image Segmentation Algorithm Based on Merging of Similar Adjacent Components

Xueguang Sun, Weigen Qiu
CT is one of the most widely used medical imaging techniques. Image segmentation is of great significance to medical image aided clinical diagnosis. Due to the complexity of structure and shape of CT image, and the inhomogeneity of organization, the commonly used image segmentation algorithm can not...

The Semantic Retrieval System for Learning Resources Based on Subject Knowledge Ontology

Bei Wu
There are many kinds of learning resources in the online education platform, but there are still many problems, such as learning resources are difficult to retrieve, search results are redundant, and can only be retrieved by keywords, but lack of semantic support. This paper integrated semantic web into...

A QoS-based User Reputation Measurement Method for Web Services

Jianlong Xu, Yindong Chen, Changsheng Zhu
In Web services environment, high-quality services discovery and selection depend on reliable users with high reputations. However, user reputation is hard to accurately obtain directly. To evaluate the reliability of users, we present user reputation measurement method, named URMM. Based on the historical...
