基于指数加权算子与自适应粒子群优化灰色模型的负荷预测

针对传统灰色预测模型GM(1,1)在预测增长较快的电力负荷时预测效果变差及数据离散度越大导致预测精度越差这一局限性,对传统灰色预测模型做进行改进。一方面,采用指数加权算子对原始数据序列进行处理,有效地减弱异常值的影响,强化了原始数据序列的大致趋势;另一方面,利用自适应粒子群优化算法与GM(1,1)模型相结合,优化GM(1,1)模型中的背景值,使其更合理,使原始信息得到更好的利用。     

林业信息化中电信运营商的机遇及应对策略

林业信息化是实现林业现代化建设的基础和重要标志,经过30多年的发展已进入全面加快发展的阶段。这为处于向综合信息服务商进行战略转型的电信运营商而言,提供了巨大的市场潜力及政策支持。但鉴于信息化过程的复杂性及长期性,运营商在面对机遇时仍需统筹规划,对优势区域进行重点投资和建设,让林业龙头企业的信息化实施带动产业信息化,并积极构建产业合作平台来弥补自身不足。     

Sustainable supply chain management in tourism

Sustainable supply chain management (SSCM) encapsulates the trend to use purchasing policies and practices to facilitate sustainable development at the tourist destination. Most research has focused on environmental aspects of manufacturing, while other aspects of sustainability or the challenges for the service sector are largely ignored. Yet SSCM is particularly important for tour operators, as the product depends on the activities of suppliers, such as accommodation, transport and activities. Therefore, tour operators' contribution to sustainable tourism will be more effective through the definition and implementation of policies that acknowledge responsibility for the impacts of suppliers. Exploratory research of SSCM practices amongst tour operators generated a wide range of examples of good practice across the whole supply chain, and recommendations are made for more widespread engagement.

Applying fuzzy linguistic quantifier to select supply chain partners at different phases of product life cycle

Owing to rapidly growing global competition, enterprises are increasingly focusing on their core competencies. The focal company faces the challenge of creating alliances with more suppliers to create outsourcing synergy and provide heterogeneous products for customers. This study proposes a fuzzy multiple attribute decision making (FMADM) method based on the fuzzy linguistic quantifier. An attempt is made to ensure that the evaluation results satisfy the current product competition strategies, and also improve the effectiveness and efficiency of the entire supply chain. The fuzzy concept is applied to both the ordinal and cardinal information. Furthermore, the fuzzy linguistic quantifier guided order-weighted aggregation (FLQG-OWA) operator can be used to satisfy the enterprise product development strategy based on different phases of product life cycle.
