[ 1 ] - الگوریتم جدیدی برای حل مسأله مسیریابی-موجودی با ارسال مستقیم
این مقاله به بررسی مسأله مسیریابی-موجودی چند محصولی چند دورهای در یک زنجیره تأمین دو سطحی؛ شامل یک تولیدکننده و مجموعهای از خردهفروشان اختصاص دارد. در مسأله مورد بررسی، علاوه بر مدیریت موجودی و برنامهریزی توزیع، برنامهریزی تولید نیز در نظر گرفته شده است. مسأله با هدف کمینهسازی مجموع هزینههای سیستم شامل هزینههای راهاندازی، توزیع و نگهداری موجودی مدلسازی شده است. محصولات توسط ناوگانی از ...
[ 2 ] - الگوریتم شاخه و کران برای مسئله برون‌بری- مکان‌یابیِ (ایستا و پویای استوار) در لجستیکِ اضطراری
فرآیند تخلیه از کلیدی‌ترین فعالیت‌های همزمان با بحران هنگام رخداد فجایع است. در پژوهش‌های مدیریت بحران، فرض بر وجود مکان‌های اسکان اضطراریِ از پیش‌تعیین‌شده‌ای است که تخلیه افراد از نواحی بحران‌زده به سوی آن‌ها انجام می‌شود. ما در این مقاله در پیِ یافتن یک پایگاه اسکان از میان مجموعة پایگاههای پیش‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌بینی‌شده هستیم که جریان تخلیه افراد از ناحیة بحران را بیشینه می‌کند و بنابراین ا...
[ 3 ] - User-based Vehicle Route Guidance in Urban Networks Based on Intelligent Multi Agents Systems and the ANT-Q Algorithm
Guiding vehicles to their destination under dynamic traffic conditions is an important topic in the field of Intelligent Transportation Systems (ITS). Nowadays, many complex systems can be controlled by using multi agent systems. Adaptation with the current condition is an important feature of the agents. In this research, formulation of dynamic guidance for vehicles has been investigated based...
[ 4 ] - Simultaneous reduction of emissions (CO2 and CO) and optimization of production routing problem in a closed-loop supply chain
Environmental pollution and emissions, along with the increasing production and distribution of goods, have placed the future of humanity at stake. Today, measures such as the extensive reduction in emissions, especially of CO2 and CO, have been emphasized by most researchers as a solution to the problem of environmental protection. This paper sought to explore production routing pro...
[ 5 ] - قیمت‌گذاری و کنترل موجودی به صورت توام برای کالاهای فاسدشدنی با در نظر گرفتن هزینه کمبود به صورت پس‌افت پاره‌ای
Determining the optimal selling price and inventory control policy for deteriorating items is one of the important issues in academic and industrial researches. In this paper, a joint pricing and inventory control model for deteriorating items is considered. The demand rate is known, continuous and functions of price and time. Shortages are allowed and partially backlogged, where the backlogg...
[ 6 ] - Considering Production Planning in the Multi-period Inventory Routing Problem with Transshipment between Retailers
Generally, the inventory routing problem occurs in a supply chain where customers consider the supplier responsible for inventory replenishment. In this situation, the supplier finds the answer to questions regarding the time and quantity of delivery to the customer as well as the sequence of customers in the routes. Considering the effect of production decisions on answering these questions, t...
[ 7 ] - Logical selection of potential hub nodes in location of strategic facilities by a hybrid methodology of Data Envelopment Analysis and Analytic Hierarchical Process: Iran Aviation case study
Hub facility location problem looks to find the most appropriate location for deploying such facilities. An important factor in such a problem is the pool of potential locations from which the optimal locations must be selected. The present research was performed to address two key objectives: identifying the factors contributing to the selection locations for hub establishment, and presenting ...
[ 8 ] - Coordination of Pricing and Order Quantity for Two Replaceable and Seasonal Products
This paper deals with the coordination of pricing and order quantity decisions for two seasonal and substitutable goods in one firm. We assume that the customers are price sensitive and they are willing to buy the cheaper products, which is known as one way and customers-based price driven substitution. First, a mathematical model is developed for one firm, which contains two replaceable produc...
