It is not easy for fuzzy model to describe the uncertainty of language, because the fuzzy model is a conventional function. The membership function of type-2 fuzzy sets(T2 FS) combines a variety of possible type-1 membership, and the primary membership function reflects the impact of uncertain factors. Online reviews are perceptive informatics, and with the time varying??the evaluation criteria also...
Based on customer-oriented e-commerce flow, this paper analyses the knowledge of e-commerce flow and builds e-commerce domain ontology and sub-ontology. Based on this analysis, this paper builds reusable model of e-commerce domain ontology by using ontology construction standard technology. This reusable model can reveal the knowledge and the relationship between knowledge of the e-commerce flow deeply...
On the purpose to adapt to ever complicated business models, an efficient consistency checking approach is needed for Business Process Model Repository to manage Multi-View models. We present a consistency checking framework to resolve the problems for service-based application. Firstly, based on business model analysis, a Multi-View business meta-model is built to act as a referred framework to find...
Logistics enterprises have developed fast in the past 20 years, and achieved very good results, but with the increasing competition of the international and domestic logistics enterprises, the logistics enterprises have not only encountered many problems, but also faced with severe challenges. Customer requirements are getting higher and higher, so logistics enterprises should focus on customer relationship...
This paper was to investigate the application of item response theory to specify an appropriate item response model for the equating of the mixed-format of multiple-choice items and open-ended items, since equating is the precondition of the development of an item bank for the Computer-Based College English Placement Test. It was shown that the equating approach based on common-item nonequivalent...
Experiment teaching for Industrial Engineering (IE) was an important component of IE teaching, traditional experiment equipment and method had revealed many limitations. In this paper, Virtual technology was applied to experiment teaching for IE according to IE curriculum requirement, virtual experimentation platform for IE was developed. New lab management system was developed, this provided a reference...
Many logistic system rely on a network of hub facilities to help concentrate flows of freight or passengers to exploit the economies of scale in transportation. Wheras , "bypass cost " and "congestion effect" also exist in hub-and-spoke network .This paper address a novel approach which unite economies of scale and "bypass cost" and reports on implementation of a route...
This paper analyzes the problems of the main credit evaluation model, and establishes an improved comprehensive evaluation model for C2C e-commerce credit. The improved model is based on the main indicators of the current credit evaluation: product quality, logistics, and service attitude, and comprehensive considerates the impact weights of various indicators. At the same time, we calculate the user's...
The purpose of this paper is to review key points about the cooperation for the inner performance of retail chain. The paper finds that to cooperate the information among retailers, stores, traffics and suppliers in the retail chain, the system should build the real time monitor system of goods traced by an RFID system firstly. The integration of retail chain information based on RFID can coordinate...
This paper research adopted the item response theory and studied the aspects such as the generation of random numbers of the students' ability and the method of identifying and selecting examination questions from the item bank. This paper put forward to the basic principle of paper intelligent-production system, the implementation process, test of fit and so on. Meanwhile the implementation process...
Location selection of distribution center is one of the most complicated problems in modern business operations; hence many mathematical algorithms were developed. The subject investigated is the regional E-supermarket with JIT distribution pattern in ring-like area, this paper proposes a two-stage model to solve its location selection problem while minimizing the number of distribution centers and...
Predicting students’ academic performance is critical for educational institutions because strategic programs can be planned in improving or maintaining students’ performance during their period of studies in the institutions. The academic performance in this study is measured by their cumulative grade point average (CGPA) upon graduating. In this study, the students’ demographic profile and the CGPA...
This paper is aimed at the image encryption scheme applicable to JPEG2000 codec. Firstly, two chaotic maps are suggested and their statistic characteristics are also analyzed. Secondly, to accomplish a controllable visual effect of encrypted image, a visual quality control model is presented, and on the basis of which, a chaotic image encryption scheme is constructed by chaotically modulating the...
