[ 1 ] - Multi-objective robust optimization model for social responsible closed-loop supply chain solved by non-dominated sorting genetic algorithm
In this study a supply chain network design model has been developed considering both forward and reverse flows through the supply chain. Total Cost, environmental factors such as CO2 emission, and social factors such as employment and fairness in providing job opportunities are considered in three separate objective functions. The model seeks to optimize the facility location problem along with …
[ 2 ] - A new mathematical model for intensity matrix decomposition using multileaf collimator
Cancer is one of the major causes of death all over the globe and radiotherapy is considered one of its most effective treatment methods. Designing a radiotherapy treatment plan was done entirely manually in the past. RecentlyIntensity Modulated Radiation Therapy (IMRT) was introduced as a new technology with advanced medical equipmentin the recent years. IMRT provides the opportunity to deliver …
[ 3 ] - یک مدل چندهدفه مکانیابی- مسیریابی برای احداث مراکز پالایش، بازیافت و دفع زبالههای بیمارستانی
در پی پیشرفت بشر و توسعه فعالیتهای انسانی، حجم ضایعات و پسماندهای خطرناک افزایش یافته و با توجه به خطرات حمل و نقل، پاکسازی، دفع و مهمتر از همه مشکلات زیست محیطی که دارند، توجه بسیاری را به خود جلب کردهاند. 10 الی 25 درصد زبالههای بیمارستانی نیز از جمله پسماندهای خطرناک به شمار میرود و از معضلاتی است که بهداشت عمومی و محیط زیست را تهدید می کند. لذا در این مقاله با ارائه یک مدل برنامه ریزی عددصحیح…
