چكيده فارسي :
امروزه باوجود اينكه زنجيرهي تأمين سبز يكي از راهبردهاي اساسي دولتها و مزيتي رقابتي براي شركتهاست، موانع و مشكلات فراواني در انتشار و گسترش آن در ميان صنايع توليدي وجود دارد. وجود ذينفعان مختلف با اهداف متفاوت و متناقض بههمراه طيف گستردهيي از عوامل تأثيرگذار كه داراي اثرات متقابل و غيرمستقيماند، دو ويژگي اصلي اين مسئله است. اين پژوهش با استفاده از ابزارهاي تحليل پويايي سيستم، تعاملات ميان ذينفعان كليدي شامل دولت، توليدكنندگان و مصرفكنندگان را بهصورت كمّي و پويا مدلسازي كرده است و الگوي انتشار مديريت زنجيرهي تأمين سبز را تشريح خواهد كرد. مدل پيشنهادي ضمن تجزيه و تحليل انواع روابط بازخوردي و علّي بين ذينفعان كليدي، روند انتشار مديريت زنجيرهي تأمين سبز را در گذر زمان بررسي ميكند. نتايج شبيهسازي و تحليل حساسيت مدل در صنعت خودروسازي ايران نشان
ميدهد كه يارانهي مصرفكننده و بهاي توليد محصول سبز اثر به مراتب بالاتري نسبت به يارانهي توليدكننده و حساسيت ترجيح مصرفكننده در گسترش زنجيرهي تأمين سبز دارد.
چكيده لاتين :
The implementation of the Green Supply Chain (GSC) has become one of the
fundamental strategies of governments today, and is recognized as a competitive
advantage for companies. Nevertheless, the diffusion and expansion of Green
Supply Chain Management (GSCM) in manufacturing industries is a complex subject and faces many barriers and difficulties. The existence of different stakeholders with different and sometimes contradictory goals, along with a wide range of influential factors that have mutually interactive and indirect effects, are two main features of this issue. Using system dynamics tools, this research models the interactions between the key stakeholders including government, manufacturers, and consumers quantitatively and dynamically, and describes the pattern of GSCM diffusion in manufacturing companies. The proposed model analyzes feedback and causal relationships among key stakeholders, evaluates the path of GSCM diffusion over time. It also evaluates the sensitivity of the results to the model parameters. Moreover, as a case study, the model is simulated in Iran's automotive industry and the results of various scenarios have been analyzed. The most important results are:
Diffusion of GSCM in automotive companies has a decreasing oscillation
pattern, and over time, the revenue of the two green producer groups and normal producers comes close together and reaches to a certain proportional level.
The amount of government subsidies to producers and consumers of green
products has an effect on GSCM diffusion. The results show that in the case of
same changes in these two parameters, the impact of the consumer subsidy (SC)
is far greater than the effect of the producer subsidy (SM), and if the
government's target is more green production, the consumption subsidy has a
better effect. GSCM releases will be significantly enhanced, if green manufacturers
can reduce the cost of their products in a variety of ways. Sensitivity of consumers to green product preferences is also effective in GSCM diffusion, but its effect is less than other factors.
