Research on Mechanism of Distributors’ Frequent Ordering Intention: A Prospect Theory Perspective  [PDF]
Bingqun Cui, Yuping Li
Modern Economy (ME) , 2015, DOI: 10.4236/me.2015.611110
Abstract: This article is to carry out in-depth mechanism exploration of influences of three different price promotion strategies on Distributors’ ordering intentions. This research finds out that Distributors have stronger intentions of determining ordering in the case of reward promotion rather than in threat promotion. However, among Distributors who have decided ordering, threat promotion can lead to stronger frequent ordering intention. Promotion intensity has strong adjustment effect on Distributors’ ordering intention both in reward and threat promotions. Rebates strategy has positive influence on Distributors’ intentions of both determining ordering and frequent ordering. The study reveals different price promotion strategies’ different influences on Distributors’ ordering intentions. This study provides a good reference for guiding enterprise managers’ application of price promotion.
Dealer’s Ordering Decision Behavior under Different Price Strategies: An Analysis Based on the Modern Behavioral Decision Theory  [PDF]
Bingqun Cui, Tingjui Chou
American Journal of Industrial and Business Management (AJIBM) , 2016, DOI: 10.4236/ajibm.2016.64049
Abstract: The modern behavioral decision theory considers that the decision subject is often in a state of bounded rationality rather than absolute rationality. From the perspective of decision behavior, this thesis based on the prospect theory deeply parses dealer’s ordering decision behavior in response to different price strategies under the random market demand, reveals the intrinsic mechanism of dealer’s ordering decision behavior in response to business price strategy, analyzes the non-pricing factors impacting dealer’s ordering decision under the price strategy, and proposes the countermoves and suggestions for enterprise in terms of business price strategy, product strategy, relationship marketing and other aspects, which will be of some references to guide the application of business price strategy and channel management practices.

Abstract: Background and objective Serum carcinoembryonic antigen (CEA) and the soluble fragment of cytokeratin 19 (CYFRA21-1) are important tumor markers (TMs) in the preoperative examination of patients with non-small cell lung cancer (NSCLC). However, the prognostic role of these markers in NSCLC patients remains controversial. The aim of the study was to investigate the clinical significance of serum CEA variances and CYFRA21-1 levels for the prognosis of NSCLC patients following surgery. Methods This retrospective study investigated the clinical records and follow-up sessions of 175 patients with NSCLC who accepted surgery and adjuvant chemotherapy. Patients were subdivided into groups based on serum CEA and CYFRA21-1 levels. Survival analysis was conducted using Kaplan-Meier method for each group. The prognostic factor was evaluated using Cox proportional hazards model. Results The overall survival (OS) of patients with high preoperative CEA or CYFRA21-1 levels was lower than that of patients with normal preoperative CEA or CYFRA21-1 levels. The OS displayed a significant difference (P=0.001) between groups with high and normal preoperative CYFRA21-1. Compared with groups exhibiting normal preoperative and postoperative levels of CEA or CYFRA21-1, the OS was shorter for groups with high preoperative and postoperative levels of CEA or CYFRA21-1. The difference of the paired groups was significant (P<0.05). Compared with the groups with normal preoperative and postoperative levels of CEA and CYFRA21-1, the OS was lower for the groups with high preoperative and postoperative levels of CEA and CYFRA21-1, which indicated a significant difference (P<0.001). The CEACYFRA211 (HHHH), CEACYFRA211 (NNHH), CYFRA21-1 (HH), CEA (HH), and male gender were identified as independent prognostic factors (P<0.05). Conclusion This study suggested that the prognosis of NSCLC patients was not significantly satisfactory if preoperative and postoperative level of serum CEA or CYFRA21-1 was higher than standard value, especially if the preoperative and postoperative levels of CYFRA21-1 and CEA were higher than the standard values. The measurement of preoperative and postoperative levels of CYFRA21-1 and CEA proved helpful for the prognosis of patients with NSCLC.
Multi-objective Optimization using Chaos Based PSO
Bingqun Ren,Weizhou Zhong
Information Technology Journal , 2011,
Abstract: As a novel optimization method, chaos has gained lots of attentions and applications in the past few years. Chaos movement can go through all states unrepeated according to the rule of itself in some area. It was introduced into the optimization strategy to accelerate the optimum seeking operation in this study. A chaos based particle swarm optimization strategy was developed to solve multi-objective optimization problems. The proposed approach is validated using several benchmark test functions and metrics on evolutionary multi-objective optimization. Results demonstrate the effectiveness and efficiency of the proposed strategy and that can be considered a viable alternative to solve multi-objective optimization problems.

Study of operator reliability in nuclear power plants
Mengzhuo Yang,Jia Gao,Bingqun Zhao,Xiangrui Huang,Zupei Shen
Chinese Science Bulletin , 1997, DOI: 10.1007/BF02882562
Abstract: The study of the reliability of operator’s diagnosis and decision-making during abnormal events with HCR model has been introduced. A new approach has been proposed by the authors to deal with the classification of HIs. The modification of T0.5 by PSFs coefficients has been discussed. In addition, it is emphasized that T0.5 and SD(σ) of response times can be used as a scale to predict and evaluate the reliability of crew/operator behavior. These processings provide improvement and refinement to HCR model arid its practical application. The experiment for operator response time of Chinese NPP using a full-scale simulator has proved the above-mentioned processings and presented the quantitative results of operator reliability in Chinese NPP.
Bayesian Factorized Cointegration Analysis  [PDF]
Kai Cui, Wenshan Cui
Open Journal of Statistics (OJS) , 2012, DOI: 10.4236/ojs.2012.25065
Abstract: The concept of cointegration is widely used in applied non-stationary time series analysis to describe the co-movement of data measured over time. In this paper, we proposed a Bayesian model for cointegration test and analysis, based on the dynamic latent factor framework. Efficient computational algorithms are also developed based on Markov Chain Monte Carlo (MCMC). Performance and efficiency of the the model and approaches are assessed by simulated and real data analysis.
Spike-and-Slab Dirichlet Process Mixture Models  [PDF]
Kai Cui, Wenshan Cui
Open Journal of Statistics (OJS) , 2012, DOI: 10.4236/ojs.2012.25066
Abstract: In this paper, Spike-and-Slab Dirichlet Process (SS-DP) priors are introduced and discussed for non-parametric Bayesian modeling and inference, especially in the mixture models context. Specifying a spike-and-slab base measure for DP priors combines the merits of Dirichlet process and spike-and-slab priors and serves as a flexible approach in Bayesian model selection and averaging. Computationally, Bayesian Expectation-Maximization (BEM) is utilized to obtain MAP estimates. Two simulated examples in mixture modeling and time series analysis contexts demonstrate the models and computational methodology.
