With the development of the information and internet technology, Vendor-Managed-Inventory (VMI) has been adopted by more and more companies. In this paper, a two-echelon supply chain inventory decision model is discussed. The products are perishable and sold over a single selling season. First a VMI model is constructed, and the supply chain members' optimal decisions are gained. Under VMI, the supplier...
Medium logic is non-classical logic system for both distinct knowledge and fuzzy knowledge. Based on medium logic and distance measure, fuzzy evaluation matrix is established with medium truth grade function, and the index of fuzzy evaluation is educed by considering positive information and negative information of the fuzzy evaluation factors. The evaluation objects are compared with each other by...
In order to accomplish the product special requirements of customers and establish the product developing platform for non-professional effectively, the requirement feature and requirement agile expression model of individualized product were put forward. The logical meta model and physical structure model of individualized product requirement information were built, the basic management and operating...
This paper mainly discusses the control strategy for an profit-oriented ecosystem which is described by multi-dimensional Lotka-Volterra model. The though comes from the concept of impulsive control which can reach the same effect with continuous control strategy but has much more advantages while considering the feasibility factors. The difference with other impulsive control strategies is that we...
The electronic commerce (EC) has fundamentally changed the environment of business, has gained attention as a major theme for enterprises to keep their competitiveness. Research on price competition and strategic behaviors in electronic commerce has advantaged improvement competitiveness of EC firms. This paper applies the game theory to study the pricing strategy of commodities in e-commerce. Firstly,...
According to literature review and a number of market research, there is an analysis about the characteristics of the domestic fragrance market. And then through the research on the consumption habits and attitudes, the result of qualitative and quantitative analysis based on the Logistic Model concludes the impact of the factors in four aspects on the willingness of purchasing perfume. According...
Domain name is a new type intangible of enterprise. For the reason that we don't recognize and measure the domain self-constructed in financial accounting system, there are little study on domain's value estimation and the factors influencing its value. For the absence of value measurement, domain name's valuation management is weak in firm. With the growth of domain trade-off, how to value it become...
This paper proposes a methodology for the design of fault tolerant controllers in parallel parking system that is modeled by a Petri net. The faults that we consider are transient sensor failures that may occur due to external interference and/or hardware malfunction. We first develop a Petri net controller that is able to keep normal operation of the system even in the presence of (possible) sensor...
Based on the analysis of some literature, this paper proposes a multi-criteria evaluation model for breast cancer susceptibility gene and implements the evaluation using Cytoscape. Most of the data come from the online supplementary table of the literature, and a little missing is completed by the BiNGO plugin of Cytoscape. The Pub Med literature search shows CDC2 gene ranked first in our final evaluation...
Legacy systems are usually made of two kind of artifacts: source code and databases. Typically, the maintenance of those systems is carried out through re-engineering processes. Although both artifacts can be independently maintained, for a more effective re-engineering of the whole system both should be analyzed and evolved jointly. This is mainly due to the fact that the knowledge expected to be...
This paper presents the implied United States federal reserve bank (FED) policy behavior under multiplicative model and shock uncertainty, defined through performance objectives, cases by using historical data. Robust system theory frameworks are used to empirically study the characteristics of the FED short-term interest rate-inflation dynamics under different circumstances by using a single-input...
Drain heat utilization system is a key part of energy saving for the thermal system. The partial analysis models of drain heat utilization with traditional Equivalent Enthalpy Drop Method (EEDM) based a different basis, and the algorithms are not well comprehensive. Based on the research on integrated mixing heater and through the mathematical derivation, the paper presented a consistent and comprehensive...
Materials handling of a cross-docking center under retail distribution environment is complicated and labour intensive. Managers are usually under enormous pressure to optimize the staff shifts, inbound schedules and operating rules to minimize handling costs while ensuring just-in-time shipments. In this study, a discrete-event simulation model is developed to understand and validate the operation...
A math model based on Data Envelopment Analysis was proposed to make comprehensive technical efficiency evaluation for coal enterprise with multi-input and multi-output systems generally, and this makes it complex and difficult to make precise technical efficiency evaluation, for example, it is hard to set evaluating weights index and difficult to get sound evaluation when the evaluation function...
Dual-failures are considered as the main contributors to service unavailability in p-cycle based mesh networks that are designed to withstand single failures. Methods such as post-failure reconfiguration and pre-failure provisioning of additional protection capacity have been considered to add another level of protection against dual-failures. In this paper, we present availability-aware service provisioning...
In this paper, we present a performance evaluation study analyzing the behavior of a generic warning message dissemination (WMD) mechanism in a 802.11p based VANET. In our WMD method, warning-mode vehicles notify nearby vehicles in order to improve traffic safety and to control traffic congestion. Our evaluation uses 2k factorial methodology to determine the most representative factors that affect...
According to Maslow's theory on human needs, this paper has analyzed the different kinds of psychological needs which game-players expect to be met when they playing online-games, then built a needs model of online-game from the perspective of players, so as to provide guidance on game-design for the developers and help bring experience for the players.
This paper studies how to establish models for predicting financial distress in China's listed companies. We firstly select 26 companies with financial distress and 54 matching companies' panel data as samples, then use panel data model to conduct an empirical study. The research indicates that: (1) The predictability precision is 91.25%, 92.5%, 91.25% and 87.5% for T-1, T-2, T-3 and T-4, respectively,...
Logistics center location is a key step of logistics system optimization, so it is important to select a proper method to assess it. First, the index system for location evaluation of logistics center is constructed by analyzing influencing factors of logistics center location. Then, the fuzzy matter-element model based on grey relevancy analysis is built in view of the fuzziness and incompatibility...
Price dispersion is an indication about the efficiency of market. An evolution model of price dispersion (EMPD) is put forward in order to research the efficiency of C2C e-business market. By concluding the influence factors of price dispersion and analyzing the trade behavior in C2C e-business market, four representative factors that are business number, business credit, customer type and transfer...
