The analytic hierarchy process (AHP) is recognised as one of the most commonly applied methods in multiple attribute decision-making (MADM) literature. In AHP, encompassing uncertainty feature necessitates using suitable theories, since dealing efficiently with subjective judgements great importance real-world problems. neutrosophic set (NS) theory and grey systems are two reliable theories whi...

The reliability of a motion mechanism is affected by corrosion, wear, aging and other components’ performance degradations with the extension service time. This paper tackles this problem proposing time-varying analysis method for uncertain mechanisms. First, model error constructed assessing difference between actual expected motion. A proposed. function discretized into several static ...

The fuzzy completion time and customer request are two main uncertain factors in the process of the actual workshop production. The scheduling model under uncertain situation based on fuzzy mathematics is established in this paper. The average customer satisfaction acts as the objective of the model. Next, a novel hybrid algorithm is obtained through improving the mutation operation of genetic ...

The crypto and digital assets ecosystems have attracted investment, regulators, speculators to their environment. As the blockchain-based framework can reduce transaction costs, generate distributed trust, enable decentralized platforms, it has become a potential new base for business models. Previous studies highlighted advantages drawbacks of each platform, such as interest rates, cost concer...

Uncertain hypothesis test is a statistical tool that uses uncertainty theory to determine whether some hypotheses are correct or not based on observed data. As an application of uncertain test, this paper proposes method differential equation fits the data not. In order demonstrate method, numerical examples provided. Finally, both currency model and stochastic used US Dollar Chinese Yuan (USD–...

The real life decisions are usually made in the state of uncertainty. This fact providesa motivation to study the behavior of uncertain phenomena. In order to deal withsubjective uncertainty, Liu (2007) founded an uncertainty theory that is a branch ofmathematics based on normality, monotonicity, self-duality, countable subadditivity,and product measure axioms. After that, u...
