ABSTRACT
As a most important index in calculating network interrelationships, there
are many definitions and more than 400 different centrality dimensions,
such as degree, and betweenness, among many others, have been developed.
All centrality indexes are calculated using the number of connection lines,
and its position in a given network. In the automotive industry, interrelationships
among partner firms are tied within a typical systemic network known as
keiretsu. As it is widely known that different partners play different
roles in assembly line, it is crucial to measure the centrality of transaction
network in the keiretsu.. Thus, the relative importance of each partner
in a connection line in a transaction network should be measured based
upon the pivotal nature of each part, which has never been proposed. This
paper contributes and advances our knowledge to the literature by proposing
a new parts-importance weighted centrality model.
