Agent-based simulation of enterprise communication network

In this paper, we consider an agent-based simulation of dynamic enterprise organization and communication networks. Along with recent progress and popularization of information technology, social sciences have been experiencing great advances in survey methodology. It has become possible for researchers to utilize huge social data with computers. However, there have been only conceptual studies in business school and few quantitative studies about enterprise organizations. In a survey of an enterprise, we evaluated strategic organization changes with graph/network analysis of the communication network constructed from email transaction data. Moreover, there is strong business needs to know how activities change according to an organization transformation. Utilizing the agent-based approach, we have constructed a dynamic model and simulation of communication over an organization structure. The result of the simulation indicates the power distribution for link degrees which is also observed in the real world as universal characteristics of the scale-free network

Digital Link: High Functional Digital Monitor Interface

We discuss a high-functional digital monitor interface, called Digital Link, which can support very high resolution monitors, high-level control of monitor functions, and flexible monitor connections. This interface is essentially an upper layer protocol and takes advantages of the physical layer of existing digital interfaces. This paper also describes a prototype system that we have developed to evaluate various aspects of the protocol.

Enterprise Organization and Communication Network

In this paper, we consider enterprise organization structures and communication networks obtained from email transaction data. Along with recent progress and popularization of Information Technology, social sciences have been experiencing great advances in methodology. It has become possible for researchers to utilize huge computational social data. However, there have been only conceptual studies in business school and very little quantitative analysis for enterprise organizations. We evaluate the strategic organization change with graph/network analysis of the communication network.
