چکیده
بازیافت دارو از جمله موضوعاتی است که اخیراً از ابعاد گوناگونی همچون کاهش عواقب زیست محیطی، تأمین داروهای ضروری و توسعه اقتصاد چرخشی مورد توجه قرار گرفته است. در این راستا، جمع‌آوری داروهای مازاد شهروندان هم با هدف بازیافت مجدد داروهای ضروری مورد نیاز بیماران و هم در راستای مدیریت اصولی پسماندهای دارویی خطرناک از طریق لجستیک معکوس بیش از پیش اهمیت یافته است. از طرفی، با تخصصی‌تر شدن موضوعات مرتبط با مدیریت لجستیک معکوس، سازمان‌ها به منظور تمرکز بیشتر بر فعالیت‌های اصلی خود و صرفه‌جویی در هزینه‌ها، به دنبال واگذاری تمام و یا بخشی از فعالیت‌های خود به شرکت‌های ارائه‌دهنده لجستیک معکوس شخص ثالث (3PRLP) هستند و در نتیجه لزوم انتخاب استراتژی عملیات مناسب توسط شرکت‌های 3PRLP اهمیت فراوانی یافته است. در این پژوهش با هدف مدیریت بازیافت دارو با محوریت دولت، خرید و جمع-آوری داروهای مازاد شهروندان به شرکت‌های 3PRLP واگذار گردیده است. در اینجا با در نظر گرفتن سه ذینفع اصلی شامل دولت، جامعه و فروشندگان دارو و اهداف هر یک، از پتانسیل سه ابزار بلاکچین، لجستیک زنجیره سرد و همکاری میان شرکت‌های 3PRLP در جهت تأمین این اهداف و انتظارات استفاده شده است و در ادامه یک استراتژی عملیات مناسب برای شرکت‌های 3PRLP پیشنهاد گردیده است. با توجه به مدلسازی ریاضی پژوهش و محاسبه تابع هدف سود شرکت‌های 3PRLP در قالب درآمد حاصل از فروش داروهای خریداری شده به دولت، نتایج نشان می‌دهد برنامه‌ریزی همکارانه بهتر از عدم همکاری بوده و از طرفی تعریف پارامتر "ضرورت دارو" بر سود نهایی شرکت‌ تأثیرگذار خواهد بود.

چکیده English

Drug recycling is one of the issues that have recently been considered from various dimensions such as reducing environmental impacts, providing essential drugs, and developing a circular economy. In this regard, collecting the surplus drugs of citizens has become more important with the aim of recycling essential ones needed by patients and managing hazardous pharmaceutical wastes through reverse logistics. On the other hand, with reverse logistics management becoming more specialized, in order to focus more on their main activities and save costs, organizations are looking to hand over all or part of their activities to Third-Party Reverse Logistics Providers (3PRLP) and as a result, it has become a vital need for 3PRLPs to choose the appropriate operations strategy. In this research, with the aim of government-centered drug recycling management, the purchase and collection of citizens' surplus drugs has been assigned to 3PRLPs. Considering the three main beneficiaries, including the government, society and drug sellers and the goals of each, we have used the potential of the three tools of blockchain, cold chain logistics and cooperation among 3PRLPs to meet these goals and expectations, and have proposed an appropriate operations strategy for 3PRLPs. Based on the mathematical modeling of the research and the obtained objective function of 3PRLPs through the revenues received from the sale of the purchased drugs to the government, numerical results show that collaborative planning is better than non-cooperation, and on the other hand, the definition of the "drug essentiality" parameter will affect the final profit of 3PRLPs.
