- Application of Topic-based Real-time Message Bus Technology in Engineering
Management of High-speed Rails
Abstract: Application of Topic-based Real-time Message Bus Technology in Engineering Management of High-speed Rails
Author Zhiyong WenGuoliang HuShaohua LiuYongni L
This paper introduces a design and implementation of distributed real-time message bus technology in engineering management of high-speed rails and trains. It illustrates the distributed self-organized architecture, message detection & filtering, topic-based message subscription and distribution of messaging bus. Besides, the application is verified according to practical needs of a high-speed rail constructor. The practices prove that such messaging bus may process messages of mass production reliably on a real-time basis in an intelligent production management system of workshops in manufacturing high-speed trains, and its application may be promoted in intelligent management systems of other manufacturing industries.
- Adoption of Social Rules in Teams of Different Sizes
Abstract: Adoption of Social Rules in Teams of Different Sizes
Author Hao JiYan Ji
Organizational structuring has been an important subject in the fields of organization science and engineering management. Due to the highly complex task environment and inherently sophisticated structure of organizations, it is often difficult to observe details of how an organization’s structure affects its performance. In computational studies of self-organizing systems, however, agents self-organize through a set of predefined rules for dealing with the dynamic changing environment and tasks. This offers a unique approach to gain insights on why and how structures evolve over time and how structuring impacts team performance under what conditions. In this paper, a computer simulation based study is carried out to explore the impact of social rules on the performance of self-organizing teams with various team sizes. The results have shown that stronger structuring favors team effectiveness in general for both small and large team sizes, while team efficiency under strong structuring peaks at a given team size and then decline with the increase of team size.
