Worker’s behaviour in manufacturing industry: An evidence from a minimum spanning tree

Abstract

A manufacturing industry contributes around 10% Malaysian economic. It provides economic opportunities for related industries and business. However, the number of accidents in manufacturing sector, including fatal accidents, has been increased from time to time. We analyze worker’s behaviour to understand the real situation. The method developed in econophysics has been used to transform the correlation structure into sub-dominant ultrametric structure. Its corresponding minimum spanning tree and the centrality measure are performed in order to identify the most influential variables.
