Exploring and Examining the Public Sense of Gain on YB Conservation and Development based on CSS2019.pdf

Subjects: Management Science >> Management Engineering

Ecological conservation and high-quality development of the Yellow River Basin (abbreviated to YB Conservation and Development) has been determined as another major national strategies of China, and public sense of gain (PSG) has been generally accepted as a macro-criterion of good governance in China New Time. This paper explored to construct the transmission mechanism of the PSG and YB conservation and development, suggested to take the PSG as a better regulation and guidance for the sound development of the Yellow River Basin. Based on the data of Chinese Social Survey in 2019 (CSS2019), this paper tried to exam the PSG on YB Conservation and Development at the beginning of this Chinese major strategy. An evaluation index system including 5 factor dimensions and 25 indices was constructed, and the normal distribution was used to describe the survey data, after that, the dominance matrix method was applied to make decision based on PROMETHEEⅡ. The empirical analysis results indicated that the PSG of the middle and upper reaches of the Yellow River was lower than the overall level of China, while that of Henan and Shandong in the lower Yellow River were both higher than its national average; and the public generally had a higher sense of gain on government public service and social civilization, however, the PSG on individual self-fulfillments of Henan and Shandong and that on economic situations of the middle and upper reaches of the Yellow River were both at a lower level.

The application of Unmanned aerial vehicles (UAVs) in both civilian and military domains is drawing increasing attention recently. This paper investigates a new routing problem of small UAVs for information collection, where UAVs can be recharged at platforms (ground vehicles or stations) distributed in the area. Different from the previous works on UAV routing, the UAVs are allowed to partially recharge their batteries according to the requirement in the following route. A mixed integer nonlinear programming model is developed to formulate the problem, where both the overall time for completing all targets’ observation and the number of UAVs are minimized. An improved adaptive large neighborhood search (ALNS) algorithm with simulated annealing criterion is designed, and a recharging platform insertion heuristic is developed to determine the recharging strategy and construct feasible solutions. To verify the effectiveness of the proposed ALNS algorithm, a set of new benchmark instances are designed based on the well-known Solomon dataset and solved. The computational results are compared with those obtained by the ant colony optimization and variable neighborhood search, which shows that ALNS performs significantly better and stable. Furthermore, analysis of the experimental results indicates that many advantages can be obtained through introducing the recharging strategy for small UAVs.
