Joint Optimization for Pedestrian, Information and Energy Flows in Emergency Response Systems With Energy Harvesting and Energy Sharing

Abstract

The rapid progress in informatisation and electrification in transportation has gradually transferred public transport junctions such as metro stations into the nexus of pedestrian flows, information flows, computation flows and energy flows. These smart environments that are efficient in handling large volume passenger flows in routine circumstances can become even more vulnerable during emergency situations and amplify the losses in lives and property owing to power outage triggered service degradation and destructive crowed behaviours. On the bright side, the increasingly abundant resources contained in smart environments have enlarged the optimisation space of an evacuation process, yet little research has concentrated on the joint optimal resource allocation between transportation infrastructures and pedestrians. Hence, in the paper, we propose a queueing network based resource allocation model to comprehensively optimise various types of resources during emergency evacuations. Experiments are conducted in a simulated metro station environment with realistic settings. The simulation results show that the proposed model can considerably improve the evacuation efficiency as well as the robustness of the emergency response system during emergency situations.

Dynamic Path Planning Analysis of Warehouse Handling Robot

“…Moreover, due to the limitation of the loading volume of the shelf, the handling robot cannot carry the goods with large volume and heavy weight, so there are certain restrictions on the types of goods and the promotion scope is narrow. Scheduling and path planning for multiple robots are also difficult and prone to conflict, which requires continuous improvement [10].…”

Mathematical Modeling Analysis of Data Attribute Encryption for Robot

“…Other scholars have proposed a full homomorphic encryption method of multisource information resources in cloud computing environment with short public key, adding a set of homomorphic encryption of perceptual resources with the same remainder pair, extracting the real resources from the ciphertext data after additive fusion, then using the Chinese remainder theorem to verify the integrity of resources, and finally fusing the new security parameters into the integrity verification parameters. After linear conversion, the number of public key elements is reduced and the size of public key is improved [4,5]. This method still has the problem that the encryption algorithm takes a long time.…”

Navigation and Positioning Analysis of Electric Inspection Robot Based on Improved SVM Algorithm

“…At a time when the energy system is developing rapidly, power grid companies are facing a huge workload [5]. In recent ten years, China has carried out the research and application of inspection robot and achieved gratifying results [6]. However, from a practical point of view, the current control robot system is still difficult to perform on its own [7].…”
