Based on traditional Vehicle Routing Problem with Time Windows, after analyzing the characteristics of fresh product distribution and studying on the time-dependent truck running time in urban areas and time-varying temperature in a day, the paper constructed the relevant cost function and established a cold chain Distribution Routing optimization model. A case with sensitivity analysis on main parameters...
Maximizing the lifetime of wireless sensor networks under constrained resources is an interesting problem that has gained increasing attention. Most methods assume an ideal link layer model when increasing the lifetime of wireless sensor networks and energy saving techniques using geographic routing remains largely unexplored. Based on a realistic link layer model, we propose a novel geographic routing...
An autonomous iteration-based approach is proposed to identify faulty links for LEO satellite systems employing intersatellite links (ISLpsilas). A designed network satellite with management responsibilities collects the routing information of communication itself with other satellites, based on which a fault diagnosis model is introduced. Then the most likely faulty link is identified by using an...
The vehicle routing problem (VRP) is an important problem occurring in many distribution systems, which is also defined as a family of different versions such as the capacitated vehicle routing problem (CVRP) and the vehicle routing problem with time windows (VRPTW). The ant colony optimization (ACO) is a metaheuristic for combinatorial optimization problems, and the max-min ant system (MMAS) is a...
An autonomous diagnosis approach of faulty links is proposed in this paper,. Given the information by which paths a designated network node with management responsibilities can communicate with certain other nodes, and can't communicate with another set of node, with the help of building diagnosis model and computing probability of link's failure the node with management responsibilities would like...
Currently, a lot of studies on network fault management have focused on the terrestrial network, which appears to not easily be applied to satellite networks. An autonomous iteration-based algorithm is proposed to identify faulty links for LEO satellite systems employing intersatellite links (ISL's). A designed network satellite with management responsibilities collects the routing information of...
