Deterrence is badly needed in the cyber domain but it is hard to be achieved. Why is conventional deterrence not working effectively in the cyber domain? What specific characteristics should be considered when deterrence strategies are developed in this man-made domain? These are the questions that this paper intends to address. The research conducted helps to reveal what cyber deterrence can do and...
The intuitionistic fuzzy set which is characterized by a membership degree and a non-membership degree, is a very powerful and useful tool to cope with fuzziness and uncertainty. Recently, the Pythagorean fuzzy set which is an extension of the intuitionistic fuzzy set has been introduced. In this paper, we focus on multi-attribute decision making with Pythagorean fuzzy information. First of all, considering...
Arms race is a typical conflict among rational and non-myopic decision-makers (DMs). Nevertheless, the assumption of basis graph model for conflict resolution (GMCR) is not suitable for this issue that each DM possesses identical priority disregarding the difference of their capabilities. In order to handle with this drawback, this paper proposes a novel methodology, entitled capability-based GMCR...
The operation scheduling is a crucial factor that can affect the economic and environmental benefits and operation reliability of the microgrids (MGs). However, widely used scheduling methods are lacking in the comprehensive consideration for the multi-objective (MO) property and robustness of the system operation. Also, the generated solutions might not diminish the disturbance of uncertainty under...
The traditional power grid is confronted with great challenges brought by the integration of renewable power sources (such as solar and wind) for their uncertain, volatile, and intermittent characteristics. This paper investigates the unit commitment problem with stochastic solar power integration and makes the following major contributions. First, the scheduling problem is formulated as a two-stage...
The procedure of the aggregation of experts' individual probability estimates for solving probability inference problems in probability trees are proposed. The suggested methodology allows to consider specific forms of uncertainty arising from the process of interaction between the expert judgments. The structure of such interactions may be different in nature — they can be consistent, compatible,...
Generally, investment decision is an evaluation of the proposed alternatives for the investor using a set of indicators. Evident, that to the start of the investment, the project should be finished and valid, however, search of investment resources and other difficulties can delay significantly start of the investment stage, which would increase risks. Therefore, it is important in addition to evaluating...
The importance of enterprise innovation risk management is constantly increasing, because it has influence on the company's leading positions, increasing its competitiveness in the domestic and international markets. It also helps to increase the economic and production potentials that are necessary to implement the innovative development strategy of the state as a whole. There are certain problems...
This paper presents a probabilistic model for optimal economic load dispatch problem to address integration of renewable energy resources into conventional power system network grid. The power generated from the solar photovoltaic (PV) array unit and load demand are recognised as random variables with given probability distribution functions. The economic load dispatch objective function is converted...
This paper investigates the potential of minimax-cost and minimax-regret approaches for centralized & determinative transmission expansion planning under uncertainty regarding market-based generation expansion, particularly when the times needed to implement transmission facilities are longer than those required to build renewable generators. The approaches can deal with non-probabilistic uncertainties...
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.
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...
Multi-area economic emission dispatch problem provides an optimal schedule for active power of generators and interchange active power between different areas by considering the operational limitations such as balance between generation and consumption, tie-line capacity limitation, generators output constraint, and transmission losses. In this paper, a hybrid method based on shuffled frog leaping...
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,...
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...
Based on the three-terminal interval number and the project risk theory, this paper discusses the problem of risk weighting in uncertain market decision-making, and puts forward the method of combining the grey system theory and the three-terminal interval number to determine the weight of decision-making. The best-selling weight, the unsalable weight and the normal weight are calculated by expert...
When launching a new product to the market, in order to get the maximal profit, it is quite important to decide its selling price. This paper introduces a new multioligopoly model, in which the market price of a product is assumed to be an uncertain variable since it is lack of the historical data. Expected value operator and optimistic value approach are used to deal with the uncertainty in the model...
Knowledge outcome improvement is critical to the success of e-communities. We build on attitude-based theory and trust literature to propose a model that explains the relationship between belief, knowledge exchange, and knowledge outcomes. This model is based on the trust-centered lens, and theorizes knowledge exchange as affected by one's constructed support, in terms of individual virtual skill...
We investigates a two-echelon supply chain with one risk-natural supplier and one loss-averse retailer where there is one short life cycles product with stochastic demand. The loss-averse preference is adopted to describe the retailer's decision-making behavior. We introduce a combined contract by organically combining the quantity flexibility contract and the buy-back contract with this issue. It...
In this paper, the problem of fleet management in electric vehicles (EVs) sharing service under demand uncertainty is studied. To solve this problem, we propose two robust methodologies to generate robust fleets reposition plans that mitigate rental demand uncertainty and imbalances. More specifically, an adjustable robust optimization model (AROM) and joint chance constraints model (CCM) are developed...
