集装箱装载问题是多约束多目标的组合优化问题,属于NP完全问题,即在有限的时间内找不到问题最优解.鉴于最大穴度算法在装箱领域的成功经验,将其与分层算法相结合构造混合算法,解决装箱问题,以求得全局最优解或次优解.运用举例和对比分析验证了该算法的有效性,能够直接应用于物资的集装箱配载. 相似文献

The fast development of machine learning and artificial intelligence has led to a great improvement of the smart tourism recommendation system, however many problems associated with the choice of transport modes in city tourism have yet to be solved. This research attempts to address this issue by proposing a model of customized day itineraries with consideration of transport mode choice. With improved particle swarm optimization and differential evolution algorithm, a nondominated sorting heuristic approach was devised. A case study was carried out in Chengdu, China to examine the performance of our approach. The results show that compared with extant methods, our approach achieves better performance. In addition, our approach can create more sensible, multifarious, and customized itineraries than previous methods. Tourism organizations and mobile map app providers could integrate our proposed model into their existing smart service systems, as part of their e-business or digital strategy for enhancing tourist experience. 相似文献

Designing a complex product such as an aircraft usually requires both qualitative and quantitative data and reasoning. To assist the design process, a critical issue is how to represent qualitative data and utilise it in the optimisation. In this study, a new method is proposed for the optimal design of complex products: to make the full use of available data, information and knowledge, qualitative reasoning is integrated into the optimisation process. The transformation and fusion of qualitative and qualitative data are achieved via the fuzzy sets theory and a cloud model. To shorten the design process, parallel computing is implemented to solve the formulated optimisation problems. A parallel adaptive hybrid algorithm (PAHA) has been proposed. The performance of the new algorithm has been verified by a comparison with the results from PAHA and two other existing algorithms. Further, PAHA has been applied to determine the shape parameters of an aircraft model for aerodynamic optimisation purpose. 相似文献

Online travel reviews have become increasingly important as a result of the intangible and heterogeneous characteristics of the tourism industry as well as the recent diffusion of social media. This exploratory case study intends to examine the comparative importance of the six heuristic attributes (reviewer location, reviewer level, reviewer helpful vote, review rating, review length, and review photo) with respect to review helpfulness in the online hotel review context. Moreover, the salience of the individual levels within each review attribute and the importance of the attributes in positive and negative review-rating groups are compared. In total, 1,158 reviews of a hotel on TripAdvisor were collected and analyzed through conjoint analyses. This study found that the review rating and reviewer helpful vote attributes are the two most important factors. Finally, three major propositions are suggested based on findings of the study, and several theoretical and managerial implications are discussed. 相似文献

Retailer customer service has been shown to lead to increases in consumer attraction and retention, but what is less apparent is whether shareholders are fully rewarded for retailers’ customer service efforts. Results from an event study on 48 retailer announcements of customer service strategies indicate that customer service increases retailer market values by 1.09 percent on average. The magnitude of this abnormal return suggests that customer service is one of the more effective ways for firms to create shareholder wealth. Further, analysis of the abnormal returns suggests that the shareholder value created by the retailer's customer service is affected by the heuristics and cues used to judge the likelihood of service delivery. Consistent with the availability heuristic, we find that services that are difficult to bring to mind and non-vivid services create significantly less shareholder value. Results further show that the retailer's reputation can also significantly inhibit the customer service's shareholder wealth creation. 相似文献

行为金融理论中的决策偏差与相对理性 总被引:5,自引:0,他引:5
行为金融 (behavioralfinance)结合了心理学与金融学的研究 ,认为人具有启发式 (heuristic)和框架依赖(frame -dependence)两大类心理决策偏差 ,从而在金融市场上造成了用标准金融理论难以解释的异常(anomalies)现象。基于行为金融理论中的决策偏差 ,并结合经济学理性假设中的理性行为假设和有限理性假设 ,提出相对理性的概念。 相似文献

我国高职院校经济类专业普遍开设了经济学(或称西方经济学、经济学基础、经济学原理)课程。由于经济学理论抽象、教学方法陈旧等,使得培养和提高学生将理论知识运用于分析和解决实际经济问题的能力显得尤为重要。需要探讨经济学教学新方法,构建启发式的教学方法体系。 相似文献
