This paper aims to introduce a new modelling approach that represents departure time, destination and travel mode choice under a unified framework. Through it, it is possible to overcome shortages of the traditional 4-step model associated with the lack of introducing actual travellers’ behaviours. This objective can be achieved through adopting discrete 3-level Nested Logit model that represen...

introduction intensity modulated radiation therapy (imrt) has made a significant progress in radiation therapy centers in recent years. in this method, each radiation beam is divided into many subfields that create a field with a modulated intensity. considering the complexity of this method, the quality control for imrt is a topic of interest for researchers. this article is about the various ...

We address the issue of multi-aircraft cooperative strategic trajectory planning in free-route airspace (FRA) this study, taking into consideration impact time-varying and altitude-varying wind forecast uncertainty. A bi-level model was established response to properties wind. The upper level focused on minimizing flight time, while lower aimed reduce potential conflicts. Meanwhile, a heuristic...

This paper examines the path of new energy development in China against backdrop carbon maximum and neutralization, studies risk large scale power transmission. In order to solve complex uncertainty challenges renewables grid expansion planning, this proposes an optimal economic planning model, which includes thermal generation start-up shutdown expenses during operation, hydro surplus water re...
