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...

Grey system theory has been widely applied to many domains such as economy, biology, agriculture, control and so on. Based on the theory of grey system, this paper established GM(1,1) grey predict modeI for the first time to forecast Chinese every hundred rural households owned computers and every hundred rural households owned mobile phone. The predicting results are almost close to the actual...

The grey system theory studies the uncertainty of small sample size problems. This paper using grey system theory in the deformation monitoring field, based on analysis of present grey forecast models, developed the spatial multi-point model. By using residual modification, the spatial multi-point residual model was developed in further study. Then, combined with the sedimentation data of Xiaol...

the shapley value, one of the most common solution concepts of cooperative game theory is defined and axiomatically characterized in different game-theoretic models. certainly, the shapley value can be used in interesting sharing cost/reward problems in the operations research area such as connection, routing, scheduling, production and inventory situations. in this paper, we focus on the shapl...

This paper designs evaluation method based on the grey theory which aims at evaluate the usage of Wireless Sensor Networks in rail traffic. With the features of the facts that: The requested data sizes for assessment via grey theory method are not big, distribution rules of the data samples are not obliged ,and the evaluation workload is small , we use grey theory to verify each index mark in c...

Purpose – The purpose of this paper is to propose a grey linear control system for regulating the price of China’s real estate and provide the necessary support to assist the relevant management departments with their policy making. Design/methodology/approach – A grey state equation of the real estate market price that can reflect both the market supply-demand price mechanism and the productio...

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...

In this paper, grey system theory and DEA are combined to establish a grey DEA model. In traditional DEA model, Input and output values of decision-making groups are all real numbers and real variables. They are replaced by grey numbers and grey variables in grey DEA model respectively. Using positioning solution method of grey linear programming, we prove the necessary condition for grey effec...
