In the last decade, due to the rapid development of GPS, electronic payment, and other technologies, as well as the popularity of smartphones, ridesharing has gradually emerged among people. This paper aims to investigate a new path-based ridesharing user equilibrium model to research 'ridesharing'. The travelers in this model include three travel modes: solo drivers, ridesharing drivers, and ridesharing passengers. In our model, a ridesharing driver can share a ride with passengers from multiple different OD pairs during the entire journey, and these passengers are not meet in this car. Meanwhile, each passenger is carried by only a ridesharing driver throughout the entire travel. Moreover, we optimize functions of travel cost to make it more realistic in our model. Finally, some numerical experiments are provided to illustrate the effectiveness and characteristics of our model. It is shown that: (1) Compared with other models, our model has lower generalized cost. (2) By inducing drivers to drive on the new roadways, the network may create a paradox. © 2024 SPIE.

Formation control of multi-agent systems(MASs) has been applied in various fields, such as autonomous navigation and target encirclement, due to its ability to facilitate coordination and achieve the desired formation or space configuration. Bearing-based formation control offers greater practicality than position-based or distance-based approaches since bearing information is inexpensive and simple to acquire, such as utilizing optical cameras.

Due to the sensitivity and unpredictability of chaos to the initial value, chaos mapping is widely used in the field of image encryption. In this paper an image encryption algorithm based on image block and double diffusion is presented. The algorithm adopts the structure of permutation-diffusion-block diffusion, which can encrypt the image in only one round, and the security is high. On this basis, a fast diffusion algorithm with row and column simultaneous diffusion is proposed, and a block diffusion algorithm using the previous pixel to influence the current pixel is designed. The SHA-256 algorithm and cipher image are used to update the initial values and parameters of the chaotic system, which enhances the ability of the algorithm to resist the chosen plaintext attack. Experimental results and encryption performance analysis show that the algorithm runs fast and has high security. © 2022 IEEE.

Multi-criteria consensus sorting model with flexible linguistic preferences based on fuzzy information granulation from the perspective of preference disaggregation

Multi-criteria group sorting (MCGS) that considers linguistic preferences involves multiple individuals evaluating alternatives and assigning them to pre-determined ordered categories based on specific criteria. Nevertheless, due to the limited availability of class information and the constrained cognitive capacity of decision-makers (DMs), it becomes challenging for DMs to furnish explicit preference information to reach consensus. Besides, decision parameters such as consensus threshold and class thresholds are also too hard to be assumed in advance. Therefore, this paper studies the preference disaggregation problem in MCGS, in which DMs are allowed to provide their pairwise comparisons in flexible linguistic expressions (FLEs) as preference information. To more fully utilize the preferences, semantic granulation is introduced. First, an individual consistency recognition model is proposed to identify inconsistent preferences and provide modification directions to the corresponding individuals. Next, semantic granulation and maximum entropy are combined into a granulation-driven information transformation model to convert the preference information based on FLEs into triangular fuzzy numbers (TFNs). Subsequently, in the consensus-driven preference disaggregation model, decision parameters and sorting results can be obtained at the premise of consensus by adjusting weights. Ultimately, to substantiate the effectiveness of the proposal, two numerical applications concerning the sorting of government venture capitals and information system suppliers are presented, along with comparative analysis, sensitivity analysis, and simulation analysis. © 2025 The Authors

Parameter estimation of fractional uncertain differential equations

引用

Soft Computing 2024年第13-14期28卷 7601-7616页

Fractional uncertain differential equations are used for forecast in this paper. It is crucial to provide an accurate estimation method since fractional uncertain differential equations hold memory effects and parameter estimation strongly depends on the accuracy of numerical schemes. A generalized moment estimation method is developed by the famous L1 numerical scheme. Adam optimization algorithm is adopted in the minimum optimization problem and the obtained optimal parameters can pass the uncertain hypothesis test. Compared with the uncertain differential equations, the fractional one holds more parameter freedom degrees and captures long-term interactions of observed data. Finally, the applications to aftershock frequency and pharmacokinetics are provided as examples. It can be concluded that fractional uncertain differential equations lead to the higher forecast accuracy which also provides some potential works on "fractional deep learning" under uncertain environments. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.
