Abstract: A bilevel coordinated optimization method for fixed and mobile charging facilities on highways, includes: constructing an optimization model framework which includes an upper-layer coordinated location optimization model and a lower-layer coordinated capacity optimization model, where the upper-layer coordinated location optimization model is used to optimize locations of charging stations and determine locations and time points of charging demands that require truck mobile charger (TMC) deployment, while the lower-layer coordinated capacity optimization model is used to optimize TMC and fixed charger (FC) capacities at candidate sites, improving an utilization rate of FCs; and performing equivalent linearization on a nonlinear problem using a big-M method and converting the problem into a mixed-integer linear programming model, and implementing a data exchange process between upper and lower layers using analytical target cascading.

Abstract: The present disclosure describes techniques for facilitating a collaborative environment. The techniques may comprise aggregating data shared by at least a subset of a plurality of users via a plurality of message threads and a plurality of virtual rooms in the collaborative environment. The data may be categorized into a plurality of categories based on determining relatedness of the data. Data associated with any category among the plurality of categories may be classified based on a plurality of types of the data associated with the category. One of the plurality of types of the data associated with the category may be displayed on a first computing device associated with a first user among the plurality of users.

Abstract: The present disclosure describes techniques for facilitating collaboration in a workspace. The techniques may comprise automatically displaying an avatar of a user in a representation corresponding to a first virtual room once an application starts to run on a computing device associated with the user. Display of the avatar in the representation may indicate that the user is in the first virtual room. A collaborative mode may be entered based on user input from the user. A visual element may be added to the avatar in response to entering the collaborative mode. The visual element added to the avatar may indicate that the user is available for a real-time communication with other users among the plurality of users.
