Powdery mildew (PM) is a typical disease in winter wheat which causes severe yield loss in China. To control the disease effectively, it is important to develop a disease forecasting model at a regional scale. In this study, the remotely sensed data that reflect crop vigor and habitat traits were adopted as candidate inputs in model development, including various vegetation indices, land surface temperature...
As an important source of logistics demand, the manufacturing industry played a role as demand promoter for the logistics industry. At the same time the level and extent of the development of the logistics industry directly related to the efficiency and effectiveness of the manufacturing enterprise. It is the key to improve the core competitiveness of enterprises. Based on the data of Dongguan logistics...
In this paper, we introduce the Guangdong Plastics Exchange's e-commerce application. The GDPE' e-commerce services include the B2B electronic transaction service, the Internet-based customer service, the logistics service, the goods charge financial service and the information service. The GDPE's innovation transaction model includes the trading method, the trading time, and the varieties of the...
In this paper, the concept of invisible conveyance ability for logistics enterprise is put forward. According to the characters of road conveyance for logistics enterprise, we establish the index system of road conveyance capacity. After delimiting and analyzing the related indexes, we build a model based on the BP neural network from three stages, and make an empirical analysis, finally discuss the...
This paper designs an improved E-commerce model and adds logistics provider to the traditional E-commerce model, puts emphasis on the mutual supervision of the third-party payment and logistics provider with reputation mechanism in order to reduce the service risks especially the payment risks in network transaction.
Maturity model is applied in armored materiel warehouse logistics capability appraisal, an armored materiel warehouse logistics capability maturity model based on ANN is proposed and the logistics capability appraisal indexes are set up. The treatment method of “the dimensional analysis plus main composition analysis” is adopted in the input index and “GA-AHP plus collecting value statistics” is adopted...
Profited from the theory of customer satisfaction(CS), the factors, influencing selection and evaluation of the third-party logistics(TPL) service provider, were analyzed by the customer satisfaction characteristics of direct logistics service, indirect logistics and third-party logistics(TPL). Firstly, this paper constructed the structural equation model(SEM) about the selection and evaluation of...
This paper uses listed companies as research object, selects 102 2006–2008 ST companies and 102 paired normal companies as an analysis sample, the other 40 selected in 2009 as a test sample. Logistic Regression is used to constructed Early warning model, the results show that: The model that contains the three indicators — a return on assets, asset-liability ratio and total asset turnover is able...
Grain is the key factor for social development. Through the vitality evaluation of the grain lifeline system of Henan province China, several appropriate proposals are provided in this paper to increase the vitality of the system. Firstly, the evaluation indexes are established based on process and security vitality indicators. Then the fuzzy comprehensive evaluation analysis is applied to evaluate...
Assessing the third-party payment risk is to use scientific methods and forecast risk, which could provide executive scientific basis. Qualitative analysis and quantified analysis are dialectical and unified. To analyze the third-party payment risk assessment with the methods of AHP and vague general evaluation model, the third-party payment business is showed as an example for research. The conclusions...
According to the characters of the logistics center location project evaluation, considering that the incomplete and uncertain intraval attribute information of the logistics center location evaluation can be reflected effectively by the traditional extension decision-making model, Extension decision-making model with grey interval number is proposed based on the grey system theory. At the course...
Combined with the characteristics of enterprise logistics system, the evaluation index system of enterprise supply logistics system was established using systematic evaluation method. The BP neural network for appraising the performance of enterprise supply logistics system was built. Through the training and simulation of neural network, it is indicated that this evaluation method proves feasible...
As market competition intensifies, numerous enterprises transfer auxiliary logistics functions to professional logistics service provider (LSP) in order to enhance their core competitiveness. Reasonable and practical evaluation method is premise of selecting LSP which is suitable for the enterprise. A comprehensive evaluation index system is established based on the requirements of various factors...
This paper designs a set of enterprise credit rating index system,in addition to traditional financial ratios, it joined the non-financial factors. then used the logical regression approach to create company's credit rating model, the result shows that the overall discrimination rate reached 95%, the models predict results accurately.
Now the rapid development of modern logistics industry is causing more and more concerns. The relationship of coordinated development between logistics and economy also becomes one of the focuses gradually. In this paper, system dynamics has been adopted to study the theory of economic pulling logistics demand, and the relationship of coordinated development between logistics and economy has been...
Regional Logistics, which is the basic industry of regional economy, is the mirror of the level of regional economy development. Scientific evaluation method is of great significance. Based on the demand/supply of regional logistics which are the original driving forces and internal factors of regional logistics, and the DEA method, this paper starts a new direction, which is different from the majority...
The paper makes the model of multilevel fuzzy optimization into location decision on distribution center of emergency logistics for emergency event, and uses information entropy and analytical hierarchy process to determine the combined weight of the indexes, which provides a new way for location decision on distribution center of emergency logistics. Finally, an example is used to validate the feasibility...
The third party logistics is a kind of service pattern, which produces under the outsourcing environment and gradually shows huge potential and vital status in the economic development. This paper constructed the index system and studied the core competence of third party logistics. With the usage of Analytic Network Process (ANP), the paper evaluated the criteria and alternatives in a feedback system...
This paper provided a new method to evaluate the priorities on location selection of the dry port. The factors that affect the facilities of the dry port were systematically analyzed and an evaluation model was built when considering the feed back and the relations between those factors. With the analytic Network Process, the dry port location is selected based on the index system in view of the factors...
Selection of suppliers is the precondition and foundation of supply chain operation. It is an important aspect to choose the best supplier for supply chain management. During recent years, how to determine suitable suppliers in the supply chain has become a key strategic consideration. However, the nature of these decisions usually is complex and unstructured. The proposed methodology consists of...
