چکیده

محیط به‌شدت رقابتی کسب‌و‌کار امروز، که با خصوصیاتی چون حاشیه‌ی سود اندک، انتظارات بالای مشتری برای دریافت محصولات با کیفیت بالا و حداقل زمان‌های انتظار شناخته می‌شود، شرکت‌ها را ملزم‌به تلاش برای تبدیل محدودیت­ها به فرصت­های کسب مزیت‌های رقابتی از طریق بهینه کردن فرآیند‌های کسب و‌کارشان  ساخته است. در چنین شرایطی، انتخاب تامین‌کننده‌ی مناسب می‌تواند نقش کلیدی در کارایی و اثر‌بخشی سازمان‌ها ایفا نموده و تاثیر مستقیمی در کاهش هزینه‌ها، سود‌آوری و انعطاف‌پذیری یک شرکت داشته باشد. پژوهش حاضر با‌هدف ارائه‌ی یک مدل انتخاب تامین‌کنندگان با در‌نظرگرفتن هم‌زمان دو مسئله‌ی کنترل موجودی و قیمت‌گذاری در زنجیره‌ی تامین ارائه گردیده است. برای ارزیابی صحت مدل و اعتبار آن از داده‌های واقعی شرکت صنایع هفت الماس شامل مواد اولیه ورودی (هات رول) و محصولات (ورق گالوانیزه) استفاده شده است. مدل ارائه‌شده در محیط نرم‌افزار گمز کدنویسی شده و نتایج آن مورد تجزیه‌و‌تحلیل قرار گرفته است.

چکیده [English]

‌In today’s highly competitive business environment, which is known by characteristics of low profitability, high customer expectations for high-quality products and minimum waiting time, make companies efforts to transform constraints into opportunities for gaining competitive advantage by optimizing their business processes. In such a situation, appropriate supplier selection can play a key role in the efficiency and effectiveness of the organization and have a direct impact on reducing costs, profitability, and flexibility of a company. The purpose of this research is to provide a supplier selection model with simultaneous consideration of two sources of inventory control and pricing in the supply chain. To assess the validity and reliability of the model, the actual data of the Seven Diamond Industries Company including input materials (Hot Roll) and products (galvanized sheets) have been used. The proposed model is coded in the GAMS software and its results have been analyzed.
