In recent years, intensive researches focused on customer equity management. This paper reviews researches on the customer equity management and concludes the numerous studies in three sectors: customer equity analysis, strategy development and customer equity optimization. We classify the customer equity evaluation models in three categories: customer retention model, customer behavior model and...
Most of existing researches focus on POMDP modeling or solution. But in some study fields, before obtaining optimal policy from a POMDP, we need first learning a POMDP model from history data. Assumed that history data including observation sequence and action sequence, the state sequence are unobservable, we derive necessary formulas for using EM Algorithm to estimate the parameters of a POMDP model,...
This paper applies the social network theory to analyze the FOODMART sales dataset which is from a large supermarket company in the United States. We first measure the node degree distribution, the average path length and the clustering coefficient. The results show that the basket network accords with the characteristics of a small world network, but its topology is different from a number of actual...
Aiming to overcome the shortcomings of P2P Grid safety, this paper presents and constructs a new P2P Grid trust model based on price motivate mechanism, and then designs and achieves an algorithm based on the model. The penalty factor of the algorithm can prevent the bad behavior and attack of malicious peers from systems; the time attenuation function reflects the trust value real and current situation...
Aiming to overcome the shortcomings of Grid resource discovery, this paper presents a Grid resource discovery model with different layers, which adopts P2P (Peer-to-Peer) technology in Grid resource discovery mechanism. The model includes three layers based on three different peers: the Super peer_Agent, Super Peer and Ordinary peer. According to the model, this paper produces a novel Grid resource...
In order to improve the dynamic and scalability of grid, the paper adopts the way fusing P2P and Grid organically, which resolves the issue that the node can join randomly and the resource-sharing can be dynamic in gird. This paper builds a resource architecture model based on P2PGrid and proposes a resource discovery algorithm fusing DHT and ant colony algorithm. This algorithm can accurately and...
The network learning environment is one of the keys who decide the quality of network-based education. The paper discusses the learning idea of constructivist theory and the design principles of learning environment based on constructivist theory. Then the paper proposes the overall framework of multi-strategic learning environment based on constructivist theory and analyzes in details the multiple...
This paper addresses the issue of modeling and understanding the dynamics of customer relationships. Our approach to modeling relationship dynamics is structurally different from the models in the existing literature. We construct a Partially Observable Markov Decision Process (POMDP) to relate the latent relationship states to the observed buying behavior. The POMDP enables the marketer to estimate...
