“…When using the NSGA-II algorithm for multiobjective optimization, it is necessary to obtain the objective function of the corresponding objective. The response surface method (RSM) is one of the effective methods to construct its objective function and has high accuracy [28,29]. The RSM method is used to optimize the experimental scheme, which can reduce the cost of computational fluid dynamics (CFD) simulation.…”

“…Although experimental measurement can provide real data, it is expensive and inconvenient to implement. Therefore, low-cost CFD simulation has considerable potential for a wide range of applications [28,29]. The AIRPAK 3.0.16 is used as CFD simulation software in this study [35].…”

“…The four ventilation performance indexes in this study are LMAA, ΔT, s Q and PMV, and their corresponding formulas are obtained by Equation ( 4). The Design-Expert software [39] can make the development of the RSM model convenient, and more detailed development of RSM models can be found in [29]. Figure 2 compares the predicted indoor temperature and wind speed along sampling L1 under three grid numbers.…”

“…x r and x s are design parameters; and c 0 , c r , c rr and c rs are the coefficients of the RSM model. The Box-Behnken design is one experimental design method of the RSM model to determine the specific operation cases as the Box-Behnken design requires fewer cases than other methods to ensure the accuracy of the RSM models [29,40]. Shen et al showed the details of developing the Box-Behnken design [27].…”

Since occupants spend most of their time indoors, an energy-saving and comfortable indoor environment are particularly important. The differences in the metabolic rate of occupants make them have different requirements for their thermal environment. To save energy under the comprehensive needs of occupants for thermal environment, the combinatorial optimization strategy based on NSGA-II and improved the TOPSIS method is proposed in this study. Firstly, the physical model of the CFD simulation is verified by experiments. Secondly, the specific operation cases corresponding to combinations of different levels of factors are determined via the RSM method, and the ventilation performance prediction model considering the metabolic rate differences and outdoor weather changes is established. Thirdly, supply air velocities and temperatures are optimized by using Pareto-based NSGA-II; the Pareto optimal solution set under different outdoor temperatures is obtained. Finally, based on the Pareto optimal solutions at different outdoor temperatures, the optimal strategy under dynamic outdoor air temperature is obtained by improved TOPSIS by the CRITIC method. The optimization of ventilation parameters significantly improved the ventilation performance, and the results show that the predicted mean vote, energy consumption, vertical air temperature difference between head and ankle levels and the local mean age of air for different metabolic rates decrease by 64.1%, 4.74%, 24.83% and 7.39% on average, respectively. Moreover, the relative energy saving rate increases as the metabolic rate increases, and the strategy facilitates adaptation to outdoor weather changes and meets the individual needs of occupants for the indoor environment. This has important implications for achieving the global goal of energy efficiency and emission reduction.

“…However, the production of this stabilizer causes more emissions of a greenhouse gas like carbon dioxide (CO2) which is hazardous to the environment. Therefore, researchers or engineers always search for new, sustainable, costeffective stabilizer alternatives to ordinary portland cement and lime [3].…”

Due to rapid urbanization and industrialization, the construction of roads increases rapidly for easy and fast transportation. Adequate land is not available everywhere to construct good roads; hence, roads are forcefully built on locally available soil such as loose soil or expansive soil. In this paper, an experimental investigation was carried out on low plastic soil (LPS) to enhance engineering properties by using chemical soil stabilization (fly ash-based geopolymer). The design of flexible pavement thickness was carried out for conventional and stabilized soil material using IITPAVE software as per IRC 37 guidelines. The results show the feasibility of fly ash-based geopolymer significant enhancement of strength were observed in terms of unconfined compressive strength (UCS) for various curing days (0 to 128 days), California bearing ratio (CBR), and Resilient modulus (MR). The microstructural analysis via Scanning Electronic Microscope (SEM) and X-Ray Diffraction Analysis (XRD) was also reveling the formation of geopolymeric gel which leads to the dense matrix to soil mass. The flexible pavement thickness significantly reduces with the application of stabilized low plastic soil.
