Social Network Analysis the Short-Term Evolution of Environment, Safety and Health Management System for a Petro-Chemical Company

Petrochemical industry was one of the important bases in economic development of Taiwan for the past decades. The environment, safety and health system (ESH) and organization was studied by survey and Social Network Analysis in the past for personnel, network operation and related information. Upon those changes in ESH issues as well as the management organization happened in the past few years. Could the qualitative and quantitative means in network analysis observe and catch the changes and differences among the system operation and personnel changes?

This study used the analytical tool Gephi to analyze the network、personnel types and relationship in the networks. As the company structured its ISO system and organization, the changes should not affect the management system or its effectiveness as the ESH issues strike. Will the company’s inner networks change as the time went by and/or manager changes in a few years? While as the qualitative analysis focused on the operation types of organization, the quantitative analysis studied the measurement indices. After collecting the organization, personnel and ESH issues changes three year before and now, the network analysis studied the indices and organization charts in order to understanding the changes. The changes in the networks, personnel types, workflows in organization were investigated by the survey in order to analyze the differences and variations. We believed this study could function as the tool for helping the company in planning and managing the ESH organization and personnel through the understanding the internal network operation. Only through the timely adjustment in those ESH networks, the efficiency and effectiveness of the organization could be guaranteed.
