چکیده

توجه به یکپارچگی تصمیمات مالی و فیزیکی برای رسیدن به رشد پایدار ارزش، امری حیاتی است. دراین‌بین مدیریت زنجیره تأمین مبتنی بر ارزش، با در نظر گرفتن عواملی مانند مدیریت سرمایه در گردش، دارایی‌ها و بدهی‌ها، تلاش دارد به این مهم دست یابد. تصمیمات مرتبط با مدیریت دارایی‌ها و بدهی‌ها و نیز نحوه و میزان تأمین مالی، همواره یکی از مهم‌ترین تصمیماتی است که هر بنگاه اقتصادی با آن مواجه است. چنین تصمیماتی تحت تأثیر برخی نسبت‌های مهم مالی قرار دارند که تاکنون در مدل‌های بهینه‌سازی زنجیره تأمین به آن‌ها توجه نشده است. در این مقاله، یک مدل برنامه‌ریزی خطی عدد صحیح مختلط به‌منظور یکپارچه‌سازی تصمیمات مالی و فیزیکی در یک زنجیره تأمین چند سطحی، چند دوره‌ای و چندمحصولی با هدف بیشینه نمودن ارزش‌افزوده اقتصادی، به‌عنوان یکی از پرکاربردترین معیارهای سنجش ارزش، ارائه شده است. یکی از مهم‌ترین وجوه متمایزکننده این مقاله، تأمین مالی از طریق استقراض کوتاه‌مدت مشروط بر رعایت نسبت‌های مهم مالی است. در ضمن، عواملی چون پیش‌خرید و پیش‌فروش در کنار خریدوفروش مدت‌دار و توجه به ارزش زمانی پول از دیگر عناصر متمایزکننده این مقاله هستند. در قسمت نتایج، پس از ارائه مسائلی با ابعاد مختلف و تائید اعتبار و کارایی مدل پیشنهادی، به بررسی اثرات تغییرات نرخ نسبت‌های مالی و وجود شرایط خریدوفروش نقدی و مدت‌دار بر روی ارزش زنجیره پرداخته شده است.

چکیده [English]

Sustainable growth of share value of a company, regardless of financial flow and integration of financial decisions with other physical decisions, is not reachable. Value based supply chain management, attempts to make it possible through managing working capital, assets and debts. Decisions regarding assets management and financing has always been though decisions every company face. Such decisions, are affected by financial ratios which has not been considered in any optimization models. In this paper a mixed integer programming is presented to integrate financial and physical decisions in a multi echelon, multi period and multi commodity supply chain in order to maximize economic value added, as a most prevalent value metric. Financing through short term borrowing considering fulfillment of financial ratios as well as option of credit buy and sell along with pre sell and pre buy are the most important contributions. Problems with different sizes are solved in order to approve effectiveness of the proposed model. The effect of financial ratios variation and various buy and sell options on supply chain value are analyzed afterward.
