The problems which remain for further studying in grey system theory are identified. Including the synthesis axiom of degree of greyness for “multiplication” and “division”, how to construct and select a suitable buffer operator? how to select and test a grey prediction model? how to build a negative grey incidence analysis models? the test rules and criteria of grey clustering evaluation models,...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Based on the existing theories of buffer operators, several kinds of buffer operators based on the interpolating function has been proposed, which all have the universality and practicability. We prove them to be strengthening buffer operators. The problem of some contradictions between qualitative analysis and quantitative forecast in pretreatment for vibration data sequences is resolved effectively.
In this paper, a new method for ranking interval grey numbers to address the challenge in multi-criteria decision making problems with interval grey numbers has been proposed. This new method involves the risk preferences of decision makers. First, we propose a new method to rank the interval grey numbers by comparing the possibility degree or whitened-value. Second, we classify the decision makers...
Since Chinese reform and opening up, the total economy has kept a rapid development trend, which also makes Chinese environmental pollution problems become increasingly serious. In recent years, Chinese government has introduced a large number of environmental protection policies to alleviate the contradiction between economic development and environmental pollution. However, the economic level, resource...
Industrial innovation platform is the engine of China's industrial structure transformation and upgrading in the new era and how to protect the interests of the cooperative units in the platform is an important factor to ensure the stable operation of the entire platform. Cooperative interest distribution is a complete and complex system engineering, which needs to consider the input, output, risk,...
Most systems in the real life are complex systems. In the study of complex systems, we tend to get highly uncertain information due to the dynamic and complexity of the cases and our knowledge limitations. Moreover, complex systems are compounded of many parts, and the methods of data collection and storage vary considerably. Hence, the data processed by complex systems are associated with multi-type...
Conflict of interests in industry-university-research cooperation is the root cause impeding the achievement of cooperation. To provide a basis for decision makers involved in this conflict, dynamic method of conflict analysis could be effectively utilized. Due to the difficulty to obtain preferences of decision makers influenced by several uncertain factors, interval grey number is introduced to...
Based on the idea of grey theory, the uncertain duration with clear extension but unclear intension in project scheduling can be characterized as the grey number. However, the operations of the grey number borrowed from other uncertainty theory had long puzzled scholars. This paper address grey project scheduling based on grey linear space. The grey linear operation based on grey linear space and...
Many decision-making problems use vague and imprecise information in linguistic variable formats as preferences. In this paper, we present a linguistic representative model based on discrete fuzzy numbers whose support is a subset of consecutive natural numbers. The arbitrary linguistic term is defined to give decision makers more freedom to express their preferences. The discrete fuzzy weighted normal...
Firstly, aiming at the characteristics of accuracy and complexity of uncertain information representation. the interval grey number extended the general grey number. Then, the concept of extended general grey number is put forward based on grey number theory, which is used to represent complex uncertain information. Secondly, according to the essence of the kernel and degree of greyness of general...
Disease cost estimation is an important and challenging issue. It serves as the key factor of hospital cost and cost control. It has been a challenge to estimate the disease cost because of the complexity of the disease pathology, individual differences of treatment process, adverse drug reaction, and complications. Especially in some high risk and high noise diseases there is another challenge from...
In the incomplete information system, no matter which dominance relation is being used to construct a rough set model the results would contain uncertainty. Considering three influence factors include the amount of information, the weight of attribute and the degree of different objects, a new grey dominance relation are defined in this paper. On this basis, a rough decision model is set up. The concept...
This paper tries to obtain the main factors influencing quality and safety of dairy products by using grey relation analysis model. We select 11 sub factors from four fields and confirm the system behavior character by applying principal component analysis. Finally, we find cow's milk yields, proportion of urban population, qualified rate of veterinary drug, qualified feed rate and the proportion...
