A multi-enterprise quality function deployment paradigm with unstructured decision-making in linguistic contexts

This paper presents an operational framework of unstructured decision-making approach involving quality function deployment(QFD)in an uncertain linguistic context.Firstly,QFD is extended to the multi-enterprise paradigm in a real-world manufacturing environment.Secondly,hesitant fuzzy linguistic term sets(HFLTSs),which facilitate the management and handling of information equivocality,are designed to construct a house of quality(HoQ)in the product planning process.The technique of computing with words is applied to bridge the gap between mechanisms of the human brain and machine processes with fuzzy linguistic term sets.Thirdly,a multi-enterprise QFD pattern is formulated as an unstructured decision-making problem for alternative infrastructure project selection in a manufacturing organization.The inter-relationships of cooperative partners are directly matched with a back propagation neural network(BPNN)to construct the multi-enterprise manufacturing network.The resilience of the manufacturing organization is considered by formulating an outranking method on the basis of HFLTSs to decide on infrastructure project alternatives.Finally,a real-world example,namely,the prototype manufacturing of an automatic transmission for a vehicle,is provided to illustrate the effectiveness of the proposed decision-making approach.

Default rules in investment decision-making:trait anxiety and decision-making styles

This study investigates the role of default options in the relationship between trait anxiety,and decision-making styles and financial decisions.One hundred and ninety-four participants were divided into three groups and subjected to three different conditions.Under each experimental condition,they had to decide whether to accept or reject investment proposals.In the first group,they had been enrolled in investment plans by default(opt-out condition),in the second group,they had not been automatically enrolled in these plans(opt-in condition),and in the third group they had to choose whether to enroll or not(control condition).The results showed that the investment decisions of anxious,avoidant,rational and dependent individuals could be facilitated by default options.In conclusion,using default options as a“nudge”can support specific groups of people to improve their financial decisions.

Spatiotemporal evolution and prediction of habitat quality in Hohhot City of China based on the InVEST and CA-Markov models

With the acceleration of urbanization,changes in the urban ecological environment and landscape pattern have led to a series of prominent ecological environmental problems.In order to better coordinate the balanced relationship between city and ecological environment,we selected land use change data to evaluate the habitat quality in Hohhot City of China,which is of great practical significance for regional urban and economic development.Thus,the integrated valuation of ecosystem services and tradeoffs(InVEST)and Cellular Automata-Markov(CA-Markov)models were used to analyze,predict,and explore the Spatiotemporal evolution path and characteristics of urban land use,and forecast the typical evolution pattern of land use in 2030.The results showed that the land use types in Hohhot City changed significantly from 2000 to 2020,and the biggest change took place in cultivated land,grassland,shrub,and artificial surface.The decrease of cultivated land area and the increase of artificial surface area were the main impact trend of land use change.The average value of habitat quality had been decreasing continuously from 2000 to 2020,and the values of habitat degradation were 0.2605,0.2494,and 0.2934 in 2000,2010,and 2020,respectively,showing a decreasing trend.The decrease of habitat quality was caused by the needs of economic development and urban construction,as well as the impact of land occupation.During this evolution,many cultivated land and urban grassland had been converted into construction land.The simulated land use changes in 2030 are basically the same as those during 2000-2020,and the habitat quality will still be declining.The regional changes are influenced by the urban rapid development and industrial layout.These results can provide decision-making reference for regional urban planning and management as well as habitat quality evaluation.

基于InVEST模型的蒲河流域景观格局及生境质量时空演变分析

[目的]通过对景观生态格局和生境质量的时空动态分析,深入研究沈阳市蒲河流域实施水土保持措施前后的生境质量响应情况,旨在为小型流域的水土保持策略提供科学依据,以促进生态经济的协同增长和区域生态的持续健康发展。[方法]基于蒲河流域2000年、2010年、2020年的土地利用数据和数字高程模型(DEM)等数据,结合FRAGSTATS和InVEST模型,运用土地利用转移矩阵、景观格局指数、生境质量及生境退化度对土地利用变化进行分析,探究响应机理。[结果](1)在2000-2010年期间,蒲河流域的耕地开发活动频繁,导致森林、草地等土地类型的比例显著下降;在2010-2020年期间,蒲河生态廊道的建设推动土地利用的变化,耕地面积流向人造地表、森林和草地。(2)在2000-2020年期间,蒲河流域的整体景观格局经历先趋于完整后破碎化的演变过程,蒲河两岸景观形成多种要素集合的密集格局,城市中心北部边缘地区生境持续破碎化。(3)从流域整体分析,2000年、2010年、2020年的生境平均质量分别为0.349,0.329,0.354,呈现出先降后升的趋势。生境退化平均值分别为0.098,0.112,0.086,与生境质量变化趋势一致。随着蒲河生态廊道建设,2020年生境质量明显改善,生态系统受到的威胁减少。从空间格局分析,东北部与西南部呈现出明显的空间分布特征;东北山区、西南湿地等区域生境质量总体较好,但有着生境退化的威胁。[结论]在水土保持措施的影响下,蒲河流域的景观生态格局得以改善,有效抑制了生境的退化现象。

基于PLUS-InVEST模型的生态脆弱区生境质量时空演变分析

基于PLUS模型预测阿坝州生态脆弱区2030年土地利用情况,并利用InVEST模型计算2000年、2010年、2020年及2030年生境质量,对其时空演变进行分析。结果表明,研究区草地、湿地退化情况显著且裸地持续增加,预计2030年裸地面积将达334.38 km^(2);与2000年相比将会有204.55 km^(2)湿地退化。驱动因子中,降雨是限制林地、湿地扩张的主要因素,侧面反映水源涵养功能的重要性;草地受各项因子的影响程度相差不大,一般生长在远离政府的地方,且其面积扩张受DEM限制;气温是导致裸地增加的主要因素。生境质量总体较高但空间分布差异较大,且有缓慢变差的趋势,预计2030年生境质量低的区域面积将比2000年增加670.28 km^(2),主要由扩张的耕地、建设用地造成。未来生境质量降低的速率将有所减缓,但仍需加强人工措施来阻止降低。

Influence of Human Activity Intensity on Habitat Quality in Hainan Tropical Rainforest National Park,China

Due to long-term human activity interference,the Hainan Tropical Rainforest National Park(HTRNP)of China has experienced ecological problems such as habitat fragmentation and biodiversity loss,and with the expanding scope and intensity of human activity impact,the regional ecological security is facing serious challenges.A scientific assessment of the interrelationship between human activity intensity and habitat quality in the HTRNP is a prerequisite for achieving effective management of ecological disturbances caused by human activities and can also provide scientific strategies for the sustainable development of the region.Based on the land use change data in 2000,2010,and 2020,the spatial and temporal variations and the relationship between habitat quality(HQ)and human activity intensity(HAI)in the HTRNP were explored using the integrated valuation of ecosystem services and trade-offs(InVEST)model.System dynamics and land use simulation models were also combined to conduct multi-scenario simulations of their relationships.The results showed that during 2000–2020,the habitat quality of the HTRNP improved,the intensity of human activities decreased each year,and there was a negative correlation between the two.Second,the system dynamic model could be well coupled with the land use simulation model by combining socio-economic and natural factors.The simulation scenarios of the coupling model showed that the harmonious development(HD)scenario is effective in curbing the increasing trend of human activity intensity and decreasing trend of habitat quality,with a weaker trade-off between the two compared with the baseline development(BD)and investment priority oriented(IPO)scenarios.To maintain the authenticity and integrity of the HTRNP,effective measures such as ecological corridor construction,ecological restoration,and the implementation of ecological compensation policies need to be strengthened.

考虑地形与生物多样性的InVEST模型及其在县域生物多样性安全格局分析中的应用

县域尺度生物多样性安全格局精细评估可为区域生物多样性保护规划、实施与管理提供科学参考。以粤北山区翁源县为例,采用InVEST生境质量模型,结合区域地形与生物多样性特征,以生境质量指数、地形与生物多样性综合指数为评价指标,开展区域生物多样性安全格局综合评估。结果表明:翁源县整体生境质量指数(HQI)较高,尤其在人为扰动较弱的水系和林区最为明显,生境质量指数较低区集中在建设用地、耕地等人类活动影响强烈区域;地形多样性综合指数(TDCI)与地形起伏度和地形坡度位置指数分布格局较为一致,而与地形湿度指数相对差值分布格局相反;生物多样性指数(BCI)分布格局受到香农-威纳指数物种多样性本底及生物多样性丰富度、人类足迹指数、生物多样性重要度与植被总覆盖度的交互影响;生物多样性综合安全格局指数与HQI、BCI及TDCI分布有较好的一致性,低风险/低脆弱(高安全)区集中在县域内城镇建设用地、交通水利和耕地等人类活动强烈区,高风险/高脆弱(低安全)区主要分布在县域北部、西北部、东南部、东北部自然保护和饮用水源等人类活动干扰微弱区。通过与区域生态保护红线等相关资料进行验证与分析,改进优化后的评估结果更能精细和客观地反映研究区生物多样性安全格局。
