چکیده | ||
طراحی کارآمد زنجیرهتأمین باعث بهبود عملکرد در سازمانها میشود. این موضوع در زنجیرهتأمین محصولات کشاورزی کمتر مورد توجه قرار گرفته است. در این مطالعه تلاش میشود با رویکردی یکپارچه به بررسی برنامهریزی برای تأمین، تولید و توزیع پرداخته شود. در این پژوهش یک مدل برنامهریزی عدد صحیح چند هدفه که به دنبال حداقل کردن هزینهها، آثار زیست محیطی و حداکثرکردن اهمیت تأمینکنندگان میباشد، ارائه شده است. در این پژوهش از ترکیبی از روشهای تصمیمگیری چند معیاره برای اولویتبندی تأمینکنندگان استفاده شد. پس از آن وزنهای به دست آمده تحت ورودیهای مدل چند هدفه در نظر گرفته شدند. مدل پیشنهادی با در نظر گرفتن ترکیبی از معیارهای کیفی و کمی و با توازن برقرار کردن بین معیارها میتواند ترکیبی از بهترین تأمین کنندگان را پیدا کند. مقایسه جوابهای حاصل از مدل ارائه شده با میزان واقعی متغیرها در بازه زمانی مورد مطالعه تفاوت آشکار در هزینهها را روشن ساخت و نتایج حاکی از آن است که مدل ارائه شده میتواند هزینهها را به میزان قابل توجهی کاهش دهد. با انجام تحلیل حساسیت بر روی یکی از پارامترهای کلیدی مدل (تقاضا)، اثر این پارامتر بر توابع هدف بررسی شد و نتایج نشان دادند در فاصله تغییرات 10 درصدی در میزان تقاضا تفاوت قابل ملاحظهای در توابع هدف مشاهده نمیشود در حالی که اگر تغییرات تقاضا در محدوده 20 درصدی تغییر کند تفاوت آشکاری در توابع هدف پدید میآید. بنابراین میتوان گفت جوابهای حاصل از حل مدل و در زمان مناسب حاکی از کارایی و صحت مدل میباشد و مبین قابلیت مدل مذکور برای پاسخگویی به شرایط واقعی است. جهت اعتبارسنجی مدل ارائه شده جوابهای حاصل با میزان واقعی متغیرها در بازه زمانی مورد مطالعه مقایسه گردیده که نتایج حاکی از کاهش هزینه در مدل ارائه شده میباشد. بنابراین میتوان گفت جوابهای حاصل از حل مدل و در زمان مناسب حاکی از کارایی و صحت مدل میباشد و مبین قابلیت مدل مذکور برای پاسخگویی به شرایط واقعی است. | ||

چکیده [English] | ||
Efficient supply chain design improves performance in organizations. This issue has been given less attention in the supply chain of agricultural products. This study uses an integrated approach to planning for supply, production, and distribution. This research presents a multi-objective integer programming model that seeks to minimize costs, environmental effects and maximize suppliers' importance. This research used a combination of multi-criteria decision-making methods to prioritize suppliers. After that, the obtained weights were considered under the inputs of the multi-objective model. The proposed model can find a combination of the best suppliers by considering a variety of qualitative and quantitative criteria and balancing the criteria. Comparing the answers obtained from the presented model with the actual amount of variables in the studied period clarified the apparent difference in costs. The results indicate that the proposed model can reduce costs significantly. The effect of this parameter on the objective functions was investigated by performing a sensitivity analysis on one of the critical parameters of the model (demand). The results showed that there is no significant difference in the objective functions within the interval of 10% changes in the amount of demand. In comparison, if the demand changes within 20%, a noticeable difference in the objective functions appears. Therefore, it can be said that the answers obtained from solving the model at the right time indicate the model's efficiency and accuracy and show the model's ability to respond to actual condition. | ||
