In this decade, due to the current competitive environment,
reputation of industrial brands is markedly dependent upon the
performance of their supply chain. Therefore, it is necessary to examine
the factors affecting their supply chain so as to increase the competitiveness
of their chain. Productivity is among the most important factors
in the advancement of industry and its evaluation requires the identification
of its important criteria. Thus, using interviews with experts
and industry executives and applying basic concepts of system dynamics,
it was endeavored in this research to identify the effective factors
in the productivity of supply chain including 27 variables and then suggest
a model to evaluate the productivity of supply chain in industrial
units. Once the model was implemented and analyzed by the simulation
software Vensim, the responses were graded and the desired results were
presented from among them.
