چکیده

رشد پایدار ارزش سهام یک شرکت بدون توجه به جریان مالی و یکپارچه‌سازی این تصمیمات با دیگر تصمیمات مرسوم زنجیره، امری بعید به نظر می‌رسد. مدیریت مبتنی بر ارزش تلاش دارد تا با در نظر گرفتن سرمایه در گردش و دارایی‌های ثابت، در کنار عواملی چون فروش و هزینه تمامی عوامل مؤثر بر ارزش را در نظر گیرد تا دستیابی به ارزش سهام پایدار امکان پذیر باشد. در این مقاله یک مدل برنامه‌ریزی عدد صحیح مختلط به منظور یکپارچه‌سازی تصمیمات مالی و فیزیکی در یک زنجیره تأمین چند سطحی، چند دوره‌ای و چند محصولی با هدف بیشینه نمودن ارزش افزوده اقتصادی، به عنوان یکی از پرکاربردترین معیارهای سنجش ارزش، ارائه شده است. مدیریت سرمایه در گردش با در نظر گرفتن اختیارات پیش خرید و پیش فروش در کنار خرید و فروش مدت‌دار، به عنوان یکی از مهمترین نوآوری‌های این مقاله در نظر گرفته شده است. در قسمت نتایج، پس از ارائه مسائلی با ابعاد مختلف و تایید اعتبار و کارایی مدل پیشنهادی، به بررسی اثرات وجود اختیارات پیش فروش، پیش خرید و خرید و فروش مدت دار پرداخته شده است. نتایج بدست آمده نشان می‌دهند که بدون وجود این اختیارات، ارزش زنجیره می‌تواند تا 64% کاهش داشته باشد.

چکیده [English]

Sustainable growth of a company share value, 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 taking working capital and fixed assets into consideration as well as factors such as sales and costs. 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. Working capital management with the option of pre-buy or pre-sell as well as the credit buy or credit sell is one of the most important contributions of this paper. Performance and validation of proposed model, are proven through solving large scale problem sizes. Then, the effect of different buy and sell options, are illustrated. Company value is 64% reduced when options were not considered.
