In this paper, we propose a method that extracts information from sequences of financial ratios and investigate the usefulness of this information for bankruptcy prediction, which constitutes an important class of financial services. We use the annual financial reports available from an external financial information services provider to extract predictors based on the Markov for Discrimination (MFD)...
Grid technology can achieve full connectivity of network resources, eliminate information silos, and thus realize resource sharing. Through standardized management of knowledge, the knowledge excavation, access and reuse can be facilitated. Because of the limitation of information management object, it is difficult to achieve the goal of intelligent logistics system, making logistics information inevitably...
Spatial data analysis and mining is more difficult to put into practice than classical data analysis due to complexity of geographical phenomena. This paper preliminary analyzed main problem faced by SDM, provided a basic framework for SDM with spatial statistical methods. Logistic regression is popular in LUCC for building relationships between land use types and influential factors by spatial sampling...
CLUE-S is a tool that can predict future land use changes. CLUE-S had been successfully applied to simulate land use change in Bandung region. The dependent variable was land use which classified into seven classes (water, forest, others, built area, plantation, dry land, and rice field). The independent variables were social economical aspect, biophysical aspect, accessibility and climate. The result...
This research is designed for manufacturing companies with sparse transportation networks to evaluate the strategic possibility of private shipment consolidation, to screen a network for opportunities to implement consolidation policies, and to optimizes the network design to maximize the amount of transportation cost savings. The proposed mathematical models and solution methodologies determine the...
This paper illustrates the feasibility and superiority of the efficiency measurement of logistics enterprises by DEA model. Under the case of CRS and VRS input oriented DEA models, we conduct an analysis on the efficiency measurement of 16 logistics public companies basing on the cross-sectional data of 2008 solved by the multi-stage DEA method. By use of DEAP Version 2.1 we can calculate CRS and...
One of the key challenges in the promotion of Web-based learning is the development of effective collaborative learning environments. Empirical studies have more recently started to focus less on establishing parameters for effective collaboration and more on trying to understand the role which such variables play in mediating interaction. The procedures and methods of collaborative learning mode,...
Because of its strong ability in capture the nature of complex systems, cellular automata (CA) have been widely used to simulate suburban land use changes and urban pattern evolution. Driving forces impacting suburban land use changes could be derived from the multi-temporal remotely sensed imageries to retrieve the transition rules of geographic CA (geo-CA). With the images of two stages ranging...
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...
Atractylodes lancea (thunb.) DC is a kind of geoherbs. The superior variety by the selecting of the A. lancea is vital to promoting production. In the present study, we had established the growth model for stem thickening, plant height increment and leaf area expansion using the logistic equation with four parameters. The growth parameters of four type's A. lancea were compared. The prediction on...
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...
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...
Based on the analysis of the international procurement status, this paper designed the evaluation index system of international provider, introduced the corresponding relationship between the evaluation index system and fuzzy Petri nets evaluation model combining with the definition of fuzzy Petri nets, then the fuzzy Petri nets evaluation model of provider in international procurement is constructed...
With the accession into the WTO, modern logistics in China possess the great development opportunity. Shanghai, Hong Kong and Guangzhou, some of the major gates to the outside world in China, plan to build themselves into major international logistics center in 5 to 10 years. Therefore the research of Logistics Infrastructure (LI) has recently become a hot topic in the logistics area. In this paper,...
The urban rail transit which has large capacity will become main transfer way and change the structure of transfer to certain extent in urban railway passenger hub. The research on the influencing factors for choosing urban rail transit is premise for the optimal arrangement of capacity on urban rail transit which matches with transportation demand in urban railway passenger hub. According to the...
The theory of procurement auction of production traditionally assumes that the bidder profit is affected by his own attribute, such as cost and quality. In our paper, we consider a logistics service e-procurement mechanism affected by information resources sharing attribute of both sides, which is based on a simple multidimensional auctions model. We also discuss an application framework of our mechanism...
In recent years, the equity ownership structure of the listed company has drawn the attention of the world. The paper introduces the nonfinancial indexes, for example equity ownership structure, to improve the financial early-warning study. Firstly, we have chosen 60 agricultural listed companies as the object of study. Secondly, we use the factor analysis method and SPSS15.0 software to establish...
Double principal-agent relationship is the initial driving mechanism for the formation and development of logistics services supply chain. The characteristics of double principal-agent mode of logistics services supply chain are investigated firstly, and then the double principal-agent model of logistics services supply chain is built based on the theory of principal-agent. Further research is done...
This study presents a multilayer perceptron (MLP) cascaded with a logistic regression (LR) model for the probability of default (PD) estimation of real-life small and medium enterprises (SMEs). The MLP does a preprocessing for LR which is used to compute PD value. The obtained raw PD values are calibrated according to the real portfolio default average. In experiments, a Turkish SME database is used...
Electronic business has made logistics collaboration more and more important. Electronic logistic (e-logistic) as an open electronic platform can realize logistics collaboration. Workflow management system (WFMS) supports the operation of e-logistic. Exact logistic business process can ensure the normal running of WFMS. With the constantly change of logistic environment, logistic business process...
