Optimizing the Flood Limit Water Level of Reservoirs in Sediment-Laden Rivers under Changing Water and Sediment Conditions: A Case Study of the Xiaolangdi Reservoir

Optimizing the flood limit water level (FLWL) of reservoirs in sediment-laden rivers under changing water and sediment conditions is an important research topic that could improve comprehensive utilization benefits. Because reservoir operation has multiple objectives in sediment-laden rivers, this study established a water–sediment mathematical model, a comprehensive benefit evaluation model, and an evaluation index system. Taking the Xiaolangdi Reservoir of the Yellow River as an example, the operation mode of the FLWL under changing water and sediment conditions was studied. Under the scenarios of incoming sediment amounts of 300–800 million tons, when using the operation mode of gradually raising the FLWL, the sediment retention period was 4–13 years longer; the lower average annual siltation of the downstream channel and minimum bank-full discharge of the downstream channel after 50 years was larger by 150–260 m3/s than the operation mode of raising the FLWL at one time. However, with enhanced benefits of sediment blocking and siltation reduction, other benefits such as water resources supply, hydropower generation, and ecological improvement are reduced. The average annual number of days that do not meet the downstream water resources supply requirements, irrigation, and ecological improvement was increased by 0.64–2.16 days, and 91–197 million kW·h reduced average annual hydropower generation. The critical amount of incoming sediment was 350 million for conversion between the two FLWL operation modes, and it will increase to 450 million tons if the incoming runoff of the Yellow River increases by 20%. After constructing the Guxian Reservoir in the middle of the Yellow River, the critical amount of incoming sediment will increase to 600 million tons. This study is of great significance for improving the utilization efficiency of water resources and promoting the socio-economic development of river basins.

Feasibility of Remanufacturing in Shoemaking Machines under the Trend of Net-zero Carbon Emissions

Achieving net-zero carbon emissions by 2050 has become a common goal in the world. An effective strategy to reduce carbon emissions will be the key to maintaining international competitiveness. Although green energy exchange is mature around the world, the relevant systems and regulations in Taiwan are not yet ready. This research examines the feasibility of shoemaking machines remanufacturing and tries to seek effective strategies to achieve carbon neutrality for the original equipment manufacturers (OEMs) of shoemaking machines. The evaluation of remanufacturing in a shoemaking machine is based on imprecise and fuzzy information. First, the feasibility evaluation model of remanufacturing in a shoemaking machine is established, including technical, economic, and resource environment feasibility criteria. Second, the comprehensive benefit evaluation model of the remanufacturing shoemaking machine is established, in which the weight of each criterion is determined by the Analytic Hierarchy Process (AHP). Finally, combined with the questionnaire, the evaluation method is verified and analyzed. The results show that the four criteria (clusters) for remanufacturing shoemaking machines have different weights, in descending order: Product design, Business model, Recycling system, and Corporate image. This implies that Product design is the most important factor for remanufacturing shoemaking machines, followed by the Business model, Recycling system, and Corporate image. Therefore, to succeed in the circular economy, OEMs need to rethink how to redesign their products from the beginning and create a new business model.

Economic Evaluation of Drought Resistance Measures for Maize Seed Production Based on TOPSIS Model and Combination Weighting Optimization

In order to optimize the appropriate drought resistance measures in the implementation of high-efficiency and intensive production of maize seed, in 2018 and 2019, maize cultivation experiments with different drought resistance measures were carried out in the arid area of northwest China, including water retention agent (SA), white plastic film mulch (WF), black plastic film mulch (BF), straw mulch (SM), and open ground flat seed as control (CK). A total of five treatments were conducted. Ten specific indicators contained four types of attributes, namely the yield, quality, water use efficiency (WUE), and economic benefit of maize seed production, aimed at constructing a multilevel evaluation system. To improve the reliability of evaluation results, subjective and objective weights of indexes were calculated using the analytic hierarchy process (AHP) and entropy weight method (EWM), respectively. Then, based on the integrated weighting method of game theory (GT), the combined weights of subjective and objective unity were obtained. Finally, with the help of the technique for order preference by similarity to ideal solution (TOPSIS), a comprehensive benefit evaluation model was established to screen out the optimal drought resistance measures. Compared with CK, different drought resistance measures significantly improved the grain quality of seeds-production corn, and the average annual yield and WUE of black and white film treatments were improved by 49.57% and 42.97% and by 65.67% and 58.21%, respectively. This proved that black film mulching (BF) could significantly increase the yield and WUE of maize seed production and effectively improve grain quality, which could be used as the best drought-resistant cultivation mode for maize seed planting in Hexi and similar areas.

Comprehensive benefit evaluation of transmission and substation project for renewable energy connection: A case in China

With the increasing demand for renewable energy connection, the scale of investment in transmission and substation projects (TSPs) is also gradually expanding. In order to reduce overinvestment and inefficiency in response to the “precise investment” of the State Grid, it is necessary to evaluate the comprehensive benefits of TSPs for renewable energy connection. Therefore, a comprehensive benefit evaluation model of TSPs for renewable energy connection is proposed in this paper. Firstly, a multi-dimensional comprehensive benefit evaluation index system from the dimensions of economy, society, environment and operation is established. Then, triangular intuitionistic fuzzy number is used to collect decision makers’ evaluation information. Best–worst method and entropy weight method are combined to calculate the combined weight of evaluation indexes. MABAC method is used to rank the comprehensive benefits of TSPs. Then, five TSPs in Gansu province are used for empirical analysis. After analyzing through the model, the weights of economic benefits, social benefits, environmental benefits, and operation benefits are 20.78%, 23.03%, 27.42% and 28.77% respectively. In addition, the score of P1 is 0.44, which is the TPS with the optimal comprehensive benefit. Finally, sensitivity analysis and comparative analysis prove the stability and rationality of the proposed model.
