Sustainability in pull supply chain through leasing services

What human has been doing on earth natural system till now is competitively unfair consuming of limited resources. Continuing this trend without thinking of Sustainable Development caused irreparable destruction. Sustainable development is a kind of development which satisfies the present generation needs without weakening the next generations abilities to meet their needs. Absolutely, sustainable development is a complex concept including different dimensions. However, most of the time, sustainable development is studied in three main areas: Environmental, Social and Economical. Today, the firms consider their goals and missions compatible with sustainable development. This research tries to design an optimal mathematical model based on moving towards sustainable pull supply chain through leasing. Sustainable leasing is an effective tool for fulfilling consumer’s demands with attaining high level of resources productivity. In the presented model; all three economical, environmental and social impacts are balanced during leasing and its EOL phase from customers and leasing company point of views. To solve the problem, multi-objective genetic algorithm (MOGA) has been applied to find the Pareto-optimal solutions. These Pareto-optimal solutions will give some trade off information about the three mentioned objectives. So decision makers can analysis the variability of economical impact in compare to environmental and social improvements. In the next step, a company of electronic leasing has been considered as a case study to validate the method and potential applications of the developed model which can help specially leasing companies to achieve sustainable development. Finally, conclusions and result will have been ended up in last chapter.
