In this work, we address a production and inventory routing problem for liquid oxygen supply chain comprising facilities, distribution network, resources. The key decisions of the involve levels plants, delivery schedule through heterogeneous vehicles, strategies national stock-out prevention. Due to complexity, propose two-level hybrid solution approach that solves using both exact metaheurist...

The German Collaborative Research Centre 637 ‘Autonomous Cooperating Logistic Processes’ tries to make a paradigm shift from central planning to autonomous control in the field of logistics. Among other things, autonomous routing algorithms based on internet routing protocols are developed. The Distributed Logistics Routing Protocol (DLRP) was originally designed for transport networks to match...

Sustainable supply chains depend on three critical decisions: production, inventory management, and distribution with reverse flows. To achieve an effective level of operational performance, policymakers must consider all these decisions, especially in Closed-Loop Supply Chains (CLSCs) remanufacturing option. In this research paper, we address the Integrated Production-Inventory-Routing Problem...

the location-routing problem is a relatively new branch of logistics system. its objective is to determine a suitable location for constructing distribution warehouses and proper transportation routing from warehouse to the customer. in this study, the location-routing problem is investigated with considering fuzzy servicing time window for each customer. another important issue in this regard ...

in this article, multiple-product pvrp with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. a mathematical formulation was provided for this problem. each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. to solve the problem, two meta-heuristic methods...

Routing in Wireless Sensor Networks (WSNs) is a very challenging task due to the large number of nodes, their mobility and lack of proper infrastructure. Since the sensors are battery powered devices, energy efficiency is considered as one of the main factors in designing routing protocols in WSNs. Most of energy-aware routing protocols are mere energy savers that attempt to decrease the energy...

using greedy clustering method to solve capacitated location-routing problem with fuzzy demands abstract in this paper, the capacitated location routing problem with fuzzy demands (clrp_fd) is considered. in clrp_fd, facility location problem (flp) and vehicle routing problem (vrp) are observed simultaneously. indeed the vehicles and the depots have a predefined capacity to serve the customerst...
