Multi-Objective Optimization Algorithm for Grouping Decision Variables Based on Extreme Point Pareto Frontier

The existing algorithms for solving multi-objective optimization problems fall into three main categories:Decomposition-based,dominance-based,and indicator-based.Traditional multi-objective optimization problemsmainly focus on objectives,treating decision variables as a total variable to solve the problem without consideringthe critical role of decision variables in objective optimization.As seen,a variety of decision variable groupingalgorithms have been proposed.However,these algorithms are relatively broad for the changes of most decisionvariables in the evolution process and are time-consuming in the process of finding the Pareto frontier.To solvethese problems,a multi-objective optimization algorithm for grouping decision variables based on extreme pointPareto frontier(MOEA-DV/EPF)is proposed.This algorithm adopts a preprocessing rule to solve the Paretooptimal solution set of extreme points generated by simultaneous evolution in various target directions,obtainsthe basic Pareto front surface to determine the convergence effect,and analyzes the convergence and distributioneffects of decision variables.In the later stages of algorithm optimization,different mutation strategies are adoptedaccording to the nature of the decision variables to speed up the rate of evolution to obtain excellent individuals,thusenhancing the performance of the algorithm.Evaluation validation of the test functions shows that this algorithmcan solve the multi-objective optimization problem more efficiently.

Function Evolution and Landscape Planning Strategy of Inland Rivers in Beilun Port City of Ningbo

In the history, the main roles of inland rivers in Beilun Port City of Ningbo were desalination,blocking tides, shipping, and flood control. Nowadays, with the continuous spread and deepening ofurbanization, the ecological environment of river courses has been destroyed. In the past, remediationmeasures based on engineering and technology played a certain role, but can not “cure the root cause”. Itshould respect the historical evolution process of river courses, and highlight the ecological service functionand leisure tourism value of river courses from the coordination perspective of urban and rural ecologicalenvironment, economic industries, society and culture in the planning ideas of ecology, production, andlife integration. Four aspects of the measures are as below: protecting and repairing the ecological matrixof river courses;building green space system and maintaining flood control functions through the waternetwork;protecting cultural heritage along the rivers;developing waterfront leisure tourism scenic area.

Characterization of saline soil for the halophytes of largest inland saline wetland of India using geospatial technology

About 23%of the surface area and 44%of the volume of all the lakes are occupied by saline lakes in the world.Importantly,agricultural diversion,illegal encroachment,pollution,and invasive species could cause these lakes to dry up completely or partially by 2025.Illegal saltpan encroachment is causing Sambhar,India’s largest saline lake,to shrink by 4.23%every decade.This study aims to characterize the soil parameters where halophytes are growing.A literature survey was conducted for halophytes and soil characteristics.The study area was divided into four zones for stratified random sampling.Soil sampling was conducted in February 2021.The soil indicators for halophyte selected were pH,electrical conductivity,moisture,salinity,organic carbon,and organic matter.The obtained results were interpolated in the geospatial platform for soil characteristic mapping.It is found that no research is conducted on halophytes of the lake.Studies on soil are also inconsistent and only six common parameters could be identified.Results show that the pH ranged 9.37-7.66,electrical conductivity was 16.1-0.38,moisture 23.37%-1.2%,organic carbon 3.29%-0.15%,organic matter 5.6%-0.2%,and salinity 8.86%-0.72%.Though these results show improved condition as compared to last few years,in long term,the lake is desiccating.During the UN Decade of Ecosystem Restoration(2021-2030),if these causes are not addressed,the ecosystem may completely dry up.

Editorial for special issue on frontiers and advances in cemented paste backfill

As an important guarantee for human survival and development,the increasing use of mineral resources has led to the generation of a large amount of tailings and slags.However,with the deep promotion of green concepts such as solid waste resource utilization and sustainable development,adding additives to tailings as filling materials can not only improve resource utilization efficiency and prevent surface collapse,but also reduce solid waste discharge to the surface,which is an effective way to fully utilize tailings resources and achieve land and energy saving,environmental protection,and waste utilization.

Modelling Dry Port Systems in the Framework of Inland Waterway Container Terminals

Overcoming the global sustainability challenges of logistics requires applying solutions that minimize the negative effects of logistics activities.The most efficient way of doing so is through intermodal transportation(IT).Current IT systems rely mostly on road,rail,and sea transport,not inland waterway transport.Developing dry port(DP)terminals has been proven as a sustainable means of promoting and utilizing IT in the hinterland of seaport container terminals.Conventional DP systems consolidate container flows from/to seaports and integrate road and rail transportation modes in the hinterland which improves the sustainability of the whole logistics system.In this article,to extend literature on the sustainable development of different categories of IT terminals,especially DPs,and their varying roles,we examine the possibility of developing DP terminals within the framework of inland waterway container terminals(IWCTs).Establishing combined road–rail–inland waterway transport for observed container flows is expected to make the IT systems sustainable.As such,this article is the first to address the modelling of such DP systems.After mathematically formulating the problem of modelling DP systems,which entailed determining the number and location of DP terminals for IWCTs,their capacity,and their allocation of container flows,we solved the problem with a hybrid metaheuristic model based on the Bee Colony Optimisation(BCO)algorithmand themeasurement of alternatives and ranking according to compromise solution(i.e.,MARCOS)multi-criteria decision-making method.The results from our case study of the Danube region suggest that planning and developingDP terminals in the framework of IWCTs can indeed be sustainable,as well as contribute to the development of logistics networks,the regionalisation of river ports,and the geographic expansion of their hinterlands.Thus,the main contributions of this article are in proposing a novel DP concept variant,mathematically formulating the problems of its modelling,and developing an encompassing hybrid metaheuristic approach for treating the complex nature of the problem adequately.

以文化之名:民国时期政学两界对“中国式边疆”现代化的思考

民国时期政学两界对“边疆”的界定除了基于政治与地理意义外,更多考察其“文化”元素,普遍认为如不从“文化”着眼,无法道尽“边疆的涵义”。这是一种典型的“中国式边疆”,形成了“中国边疆”独特的“边疆性”,由此中国边政内涵也极为丰富。“边疆性”之形成,既然主要来自“文化”因素,那么边疆现代化的实质就是要消除“边疆性”,让其失去“文化上的意义”。所谓“文化”,包括物质文化和精神文化。消除“边疆性”并非抹杀文化,而是通过发展经济和增进认同,按李安宅的观点,就是要通过物质和精神的“区域分工”,也就是要实现边疆现代化及其与内地的一体化。

为提高LNG船舶安全区设置的科学性,保障内河水域LNG船舶的通航安全,提出了一种基于速度特征的内河LNG船舶三维动态安全区建模方法。基于LNG船舶航行方向和速度变化的特点,将传统速度的线性分布模型改进为随机分布模型;利用区域分解法,将复杂的三维几何区域分解成若干个子区域,建立相应的边界方程;基于船舶间极限通过设定约束条件,根据其几何形状,运用停船视距理论、船舶漂移计算方法和富余水深计算方法对安全区内部结构不同方位的安全距离进行数值求解。针对某内河LNG船舶,通过设置不同速度条件进行仿真验证。研究结果表明:该模型能较真实反映船舶安全区在速度影响下的差异变化,为内河LNG船舶航路规划起到参考作用。

我国绿色财政产出效率的地区差异、动态演变及时空收敛性

本文使用2007—2020年我国省级面板数据,测算并分析我国绿色财政产出效率差异、变化趋势、效率损失来源以及未来提升重点,并对绿色财政产出效率的地区差异、动态演变及时空收敛特征进行探究。研究发现:我国绿色财政产出效率的地区差异逐渐缩小、均衡化水平不断提升,效率总体差异变化主要来源于财政发展不同水平地区之间的交叉重叠影响;各省的绿色财政产出均存在不同程度的效率损失;不同产出效率类型省份之间存在效率等级的动态转移现象,具有正向空间溢出效应;我国绿色财政产出效率不存在σ收敛,但存在明显的空间β收敛特征,各省的绿色财政产出效率最终会趋向于同一个最优稳态水平。
