Widely used deep neural networks currently face limitations in achieving optimal performance for purchase intention prediction due to constraints on data volume and hyperparameter selection.To address this issue,based on the deep forest algorithm and further integrating evolutionary ensemble learning methods,this paper proposes a novel Deep Adaptive Evolutionary Ensemble(DAEE)model.This model introduces model diversity into the cascade layer,allowing it to adaptively adjust its structure to accommodate complex and evolving purchasing behavior patterns.Moreover,this paper optimizes the methods of obtaining feature vectors,enhancement vectors,and prediction results within the deep forest algorithm to enhance the model’s predictive accuracy.Results demonstrate that the improved deep forest model not only possesses higher robustness but also shows an increase of 5.02%in AUC value compared to the baseline model.Furthermore,its training runtime speed is 6 times faster than that of deep models,and compared to other improved models,its accuracy has been enhanced by 0.9%. 展开更多

Recycling is viewed as a key component in a circular economy and serves as an ideal solution for promoting sustainability.During the global plastic crisis,plastic recycling practices have been adopted worldwide,leading to the production of various products made from recycled plastics(PRP).Nevertheless,a gap persists between consumption and demand for such products,which is primarily attributed to a lack of comprehension from the consumer perspective.Given the pivotal role consumers play in the adoption of these products,this study explores consumers’intentions to purchase PRP.This is particularly significant in Vietnam,which is an emerging economy aspiring to achieve the objectives of a circular economy and sustainable development.Utilizing an integrated cognitive-emotional framework comprising the Valence Theory and the Norm Activation Model,data from 564 Vietnamese students were gathered and analyzed using structural equation modeling.The results show that awareness of consequences is a major driver of consumer purchase intentions,followed by perceived ease of application and monetary incentives.The results also indicate that health concerns have the strongest effect on purchase intention and in the negative side,meaning that the health-related risk is the primary concern for consumers during the decision-making process.This research holds substantial value for academics and managers,as it aids in the theoretical exploration and the formulation of strategies to improve consumer acceptance of PRP. 展开更多

This research introduces a novel approach to improve and optimize the predictive capacity of consumer purchase behaviors on e-commerce platforms. This study presented an introduction to the fundamental concepts of the logistic regression algorithm. In addition, it analyzed user data obtained from an e-commerce platform. The original data were preprocessed, and a consumer purchase prediction model was developed for the e-commerce platform using the logistic regression method. The comparison study used the classic random forest approach, further enhanced by including the K-fold cross-validation method. Evaluation of the accuracy of the model’s classification was conducted using performance indicators that included the accuracy rate, the precision rate, the recall rate, and the F1 score. A visual examination determined the significance of the findings. The findings suggest that employing the logistic regression algorithm to forecast customer purchase behaviors on e-commerce platforms can improve the efficacy of the approach and yield more accurate predictions. This study serves as a valuable resource for improving the precision of forecasting customers’ purchase behaviors on e-commerce platforms. It has significant practical implications for optimizing the operational efficiency of e-commerce platforms. 展开更多

The advent of the digital age has profoundly changed consumers’mindsets and habits.The rapid development of e-commerce and the widespread use of mobile applications have created enormous demand for individual recommendation systems based on mass data.This system not only increases the convenience of purchases and conversions but also alters the purchasing behavior of consumers,leading them to make choices subconsciously.Potential risks associated with large-scale data sharing and usage have heightened consumer concerns regarding privacy,thereby weakening the foundational trust in platforms and deterring them from shopping.Additionally,the rapid growth of e-commerce in the digital age,coupled with changing market circumstances,has intensified psychological pressure on consumers,making their decision-making processes more complex and difficult.Furthermore,the program will explore issues related to improving customer experience,developing individual marketing strategies,and designing customer loyalty plans.It will also address questions of privacy in a digital environment,the dilemmas of excessive or disruptive consumption behavior,and the complexity and diversity of consumer behavior in the face of digital change.The objective of this study is to develop a fear study that will enable a better understanding of the impact of online shopping on consumer behavior and provide a strategic guide for retailers to meet the challenges and opportunities presented by the digital age. 展开更多

Objective To analyze the impact of the centralized drug procurement policy on pharmaceutical enterprises,and put forward some suggestions for improving China’s centralized drug procurement policy.Methods Through literature analysis and comparative research,the relevant policies and implementation effects from the“4+7”drug procurement pilot to the seventh batch of volume procurement were sorted out,and the impact of the procurement policy on pharmaceutical enterprises was analyzed.Results and Conclusion The centralized drug procurement policy has continuously improved the enthusiasm of enterprises to participate in bidding,and the consistency evaluation work has been carried out well.However,there are also some problems,such as the reduction of enterprise profits,the difficulty of enterprise operation,the decline in the quality of winning drugs,and the insufficient innovation ability and the supply capacity of enterprises.In this regard,enterprises should reasonably control the cost of drugs to ensure the stable supply of winning drugs.Besides,enterprises should create brand effect for their timely transformation and development.While strengthening pharmaceutical innovation,they can change from low-level generic drug production to R&D innovation.The government should pay close attention to the impact of centralized procurement on the quality and efficiency of enterprise drugs.For instance,the government should improve the pricing rules for drug procurement and increase supervision of drug quality and supply.At the same time,it should give certain policy and financial support to enterprises’technological innovation and talent introduction. 展开更多

A two-period duopoly model is developed to examine the competitive effects of targeted advertising with customer recognition (TACR). In the model, two competing firms sell goods to end consumers in the first period, during which customer recognition is obtained. In the second period, advertising can be targeted toward different consumer types. Advertising is assumed to be persuasive in the way that consumer valuation is increased. Equilibrium decisions and profits in each period are derived, showing that the firm who loses the current competition will win in the future. As a result, forward-looking firms price less aggressively so that their long-term profits can be enhanced with the help of TACR. Particularly, TACR improves profits through three important effects: valuation increasing, customer poaching, and anti-competition. Finally, this paper investigates the welfare issues, showing that firms enhance profits at the expense of consumer surplus. It is, therefore, suggested that public sectors take a step to protect consumers with the rapid development of targeting technology. 展开更多

This paper presents a mathematical model for components/parts unification (CPU) policy. This model considers two components/parts that are functionally interchangeable but purchased from suppliers with different prices and quality characteristics. Because of the buyer's quality preference and suppliers' discount rates for bulky purchases, the model assists the procurement manager to determine how best to purchase the components/parts to meet its demand while minimizing the total acquisition costs. 展开更多

This research plans to evaluate the changes and evolutions from the real world of key account management compared to literature review: How decisions are taken, what processes help to be successful on tenders, how to cooperate on a world basis, what methods facilitate conclusions. This work looks for a measure of evolution and changes during a negotiation process by KAM compared to existing literature research. Key account negotiators take strategic dimensions into account when starting a negotiation process. They measure the cost of negotiations, help their clients to position themselves properly, and develop partnerships. In general, researchers are more interested in organization and clients than in integrated processes. The process analysis is built on an in-depth analysis of Key Account Management (KAM) on three matters: an in-depth interview of 20 Key Account Managers from such companies as Air Liquide, Matra, Alcatel, GEC Alstom, Bull, EADS, PPG, an advertising agency and Omnicom on prospecting, partnerships, client’s effectiveness optimization, client’s qualification, lobbies, networks, international accounts. This research shows how KAM faces complex situations, how training and monitoring bring solutions to difficult situations, how information is managed through transparency relationships, TV shows, press media, information from shows and fairs, competitors evaluation. This work conceptualizes the KAM negotiation process and permits to managers to identify the different negotiation steps from their numerous mutual professional witnesses. The number of companies could have been larger, but we interviewed each salesperson in depth. Future work on key account salespeople should consider the following subjects: influence of KAM on tenders. Which ethical steps KAM can take with client companies to improve results. Innovation perception by clients is as a tool for success. 展开更多
