چکیده

این پژوهش، در یک شهرک صنعتی دارویی، شامل روابط بین تأمین‌کنندگان، مجموعه تولیدکنندگان و مشتریان، با استفاده از مفهوم هاب تأمین تحت مدیریت 3PL بهینه شده است. در این راستا یک مدل جدید ریاضی برای زنجیره تأمین این مجموعه صنعتی در حالت پایدار پیشنهاد شده است که محورهای اقتصادی، اجتماعی و زیست‌محیطی در این مدل لحاظ و سپس توسط نرم‌افزار گمز به‌طور دقیق حل شده است. هدف، کمّینه‌کردن هزینه‌های تحمیل‌شده به سیستم، شامل هزینه عملیاتی هاب تأمین، هزینه حمل‌ونقل مواد خام و محصولات، هزینه سفارش‌گذاری، هزینه انبارداری مواد خام و محصولات نهایی، هزینه کمبود محصولات نهایی که به شکل پس‌افت در نظر گرفته شده‌اند، هزینه استخدام و اخراج نیروی انسانی و هزینه معدوم­کردن ضایعات این کارخانه‌های دارویی است. همچنین یک روش ابتکاری مبتنی بر آزادسازی در این پژوهش پیشنهاد شده است؛ سپس مجموعه‌ای از مسائل نمونه‌ای با الهام از مطالعه موردی اجرا و پیاده‌سازی شده‌‌اند. در ادامه نتایج دقیق به‌دست‌آمده توسط نرم‌افزار گمز و روش ابتکاری با یکدیگر مقایسه شدند. در انتها به‌منظور درک بهتر میزان حساسیت‌پذیری محورهای مختلف رویکرد پایداری (اقتصادی، اجتماعی و زیست‌محیطی)، چندین تحلیل حساسیت مختلف صورت پذیرفته و یافته‌های مدیریتی و عملیاتی مفیدی در این خصوص برای مدیریت ارشد چنین صنایعی ارائه شده است.

چکیده [English]

This study, in a pharmaceutical industrial zone, including relationships between suppliers, manufacturers and customers, are optimized using the concept of supply hub under 3PL management. In this regard, a new model for the supply chain of this industrial zone has been proposed in a sustainable approach, in which the economic, social and environmental axes are considered and then carefully solved by GAMS software. The goal is to minimize the costs imposed on the system, comprising the operating cost of the supply hub, the cost of transporting raw materials and products, the cost of ordering, the cost of storing raw materials and finished products, the cost of shortage of finished products considered as back-ordered, the cost of hiring and firing as well as the cost of destroying the waste of these pharmaceutical factories. An efficient heuristic relaxation-based approach is proposed in this paper. Then, a series of sample instances inspired by the case study have been implemented. The results obtained by GAMS and the proposed heuristic method are compared. Finally, to understand the sensitivity of different axes of the sustainability approach, several sensitivity analyses have been conducted and useful managerial and operational insights are presented for top management of such industries.
