Due to mandatory emission reduction and rising oil prices electric vehicles are about to be introduced in mass markets. This paper presents a system dynamics model of Chinas development strategy of electric vehicle industry. The focus of the paper is to study the influence of four major dynamic factors government policies, technology innovation, market demand and competitive ability. It gives an overall scenario of the development and highlights the major problems faced by Chinese electric vehicles industry, and how SD modeling can be used for the analysis of the industry developing policy. The model has been used to simulate the influence of these dynamic factors for 20 years, and a serious of policy tests and some useful policy suggestions were put forward. The result suggested that government support will still play a key role in a long-term.

“…The systems dynamics modeling technique has been suggested for the quantitative evaluation of resilience of industrial systems (Salzano et al, 2014). Systems dynamics was utilized to proffer solution to the complex dynamic structure of sugar industry management (Javalagi and Bhushi, 2007). Rwashana et al, 2014, in their work applied systems dynamics modeling technique to the health care system to understand the dynamics of neonatal mortality in Uganda.…”

Purpose – Globally, supply chains compete in a complex and rapidly changing environment. Hence, sustainable supplier selection has become a decisive variable in the firm’s financial success. This requires reliable tools and techniques to enhance understanding on how supplier behavior evolves with time and to select the best sustainable supplier. System dynamics (SD) is an approach to investigate the dynamic behavior in which the system alterations correspond to the system variable changes. Fuzzy logic usually solves the challenges of imprecise data and ambiguous human judgment. The paper aims to discuss these issues. Design/methodology/approach – This work presents a novel modeling approach for integrating information on supplier behavior in fuzzy environment with SD simulation modeling technique. This results in a more reliable and responsible decision-support system. Supplier behavior with respect to relevant sustainability criteria were sourced through expert interviews and simulated in Vensim to select the best possible sustainable supplier. The simulation runs were carried out in four scenarios, namely, past, current, future and average time horizon for four different suppliers. A multi-criteria decision-making model was presented to compare results from the systems dynamics model. Findings – An increase in the rate of investment in sustainability by the different suppliers causes an exponential increase in total sustainability performance of the suppliers. The growth rate of the total performance of suppliers outruns their rate of investment in sustainability after about 12 months. Originality/value – While a significant work exists regarding supplier selection, little work has been found that investigates how to insure sustainable suppliers maintain their status for a long period of time.
