this paper applies a new multi attribute decision-making (madm) model to help companies for enterprise resource planning (erp) selection problem based on balanced score card method. this paper uses three-parameter interval grey numbers which is derived from grey theory (was proposed by j. deng). this numbers is used instead of linguistic variables. beside, a new weighting method that outcomes f...
An accurate and stable short-term traffic forecasting model is very important for intelligent transportation systems (ITS). The forecasting results can be used to relieve traffic congestion and improve the mobility of transportation. This paper proposes a new hybrid model of grey system theory and neural networks with particle swarm optimization, namely, GNN-PSO. The proposed hybrid model can e...
Based on the set of an indicator system and the grey relational analysis model, the regional technology innovation ability of China is evaluated. It shows that the regional technology innovation ability of China is improving gradually; the level of technology input and the environment of technology innovation are promoting the development of the technology innovation ability of China, the level...
This paper constructs a four factors theoretical model of Chinese small and medium enterprises based on the “cartoon characters’ reputation enterprise marketing and management capabilities – protection of the cartoon image institutional environment” by literature research, case studies and investigation. The empirical study show that the greatest impact on current merchandising rights income is...
Grey numbers facilitate the representation of uncertainty not only for elements of a set, but also the set itself as a whole. This paper utilizes the notion of possibility degree from grey system theory coupled with the idea of dominance relation and partial order set (poset) from rough theory to represent uncertain information in a manner that maintains the degree of uncertainty of information...
It is important nowadays to provide guidance for individuals or organizations to improve their knowledge according to their objectives, especially in the case of incomplete cognition. Based on grey system theory, a knowledge architecture which consists of grey elements including knowledge fields and knowledge units is built. The method to calculate the weightiness of each knowledge unit, with r...
Ecological environment quality comprehensive evaluation evaluate different cells’ ecological environment quality, on the basis of region eco-environment investigation , the indexes and math methods selected according to the region, to discover the problems and put forward comprehensive father measures. In electronic government spatial decision-making assistant systems, Estimate the region’s eco...
The idea proposed in this paper utilizes an efficient image retrieval system that is based on computation and combination of grey level, shape and texture features. The proposed system calculates various grey level features which are used to extract attributes from an input image. Grey Level Co-occurrence Matrix is used to compute the texture feature of a given image while the Shape feature fin...
Background: The efficiency of health system services is a critical measure for societies development. During the last fifty years, the world has witnessed a massive increase in health expenditure, and health-related cost, especially in developing countries, is the main obstacle in the way of advance in health care systems. As a remarkable portion of this cost belongs to blood supply chain...
The rapid development of agricultural modernization in Hubei province has an influence on cultivated land resources variations to a certain degree. This paper used grey relational analysis method,combined with Hubei province cultivated land area decreased data within the year covering 2000 to 2010 and agricultural modernization development index data, then analyzed the influence relationship be...
