Discrete facility location, Distribution center, Logistics, Inventory policy, Queueing theory, Markov processes, The distribution center location problem is a crucial question for logistics decision makers. The optimization of these decisions needs careful attention to the fixed facility costs, inventory costs, transportation costs and customer responsiveness. In this paper we stu...
We study a multi-echelon joint inventory-location model that simultaneously determines the location of warehouses and inventory policies at the warehouses and retailers. The model is formulated as a nonlinear mixed-integer program, and is solved using a Lagrangian relaxation-based approach. The efficiency of the algorithm and benefits of integration are evaluated through a computational study.
In this paper, it was an attempt to be present a practical perishability inventory model. The proposed model adds using spoilage of products and variable prices within a time period to a recently published location-inventory-routing model in order to make it more realistic. Aforementioned model by integration of strategic, tactical and operational level decisions produces better results for sup...
در بحث امدادرسانی به مصدومان بلایای طبیعی و غیرطبیعی، هدف اصلی یک زنجیره این است که اقلام موردنیاز مانند آب مواد غذایی، دارویی، پناهگاه سایر ملزومات سریعترین زمان ممکن دردسترس قرار بگیرد تا از تعداد مرگومیر ناشی وقوع بلایا حد امکان کاسته شود؛ بنابراین طراحی توسعه اجراییکردن میتواند نقش مهم بزرگی دستیافتن پاسخ مناسب ایفا کند. بارزترین تفاوتها برخورد با ، غیرقابلپیشبینیبودن تقاضا نظر ...
Abstract A network of queueing-inventory systems is considered where the inventories are replenished by a common central server. Travel times for transport items send out from center and an adaptive dispatching regime to direct transportation towards locations with incorporated in model. The stationary distribution system product form explicitly given. An optimization procedure developed find g...
Solving the Inventory Location-Routing Problem can been seen as an approach to optimize both a supply chain design and its operations costs. Assumptions consider that vehicles might visit more than one retailer per route and that inventory management decisions are included for a multi-depot, multi-retailer system with storage capacity over a discrete time planning horizon. The problem is to det...
Vendor-managed inventory (VMI) is one of the emerging solutions for improving the supply chain efficiency. It gives the supplier the responsibility to monitor and decide the inventory replenishments of their customers. In this paper, an integrated location–inventory distribution network problem which integrates the effects of facility location, distribution, and inventory issues is formulated u...
today, the effective inventory management plays an important role in the success of the organizations in the new business environment. it is not clearly possible for the organizations that store hundreds of inventory items to economically design an inventory management policy for each inventory item separately. moreover, various inventory items may play quite different roles in the business of ...
