“…Robustness refers to the ability of tolerating perturbations that might affect the system's functional body [29,30]. For EMS, it reflects the ability to provide medical rescue service when uncertainties occur.…”

Abstract:It is important for station managers and emergency medical service (EMS) managers to understand the available ambulance stations for each metro station. EMS managers can make use of this information to reallocate EMS resources to improve the performance of EMS system. Station managers can pay attention to the safety management of metro stations with fewer medical rescue support. This paper aims to develop a selection diversity index to address two questions: "How many available ambulance stations are available or can serve the rescue of metro stations in emergency?" and "Which ambulance stations are most vulnerable?". To implement this measure in practice, definition of available ambulance stations for rescue of metro stations is described based on the response time threshold. The selection diversity is proposed to measure the preparability of medical rescue service for metro stations. To show proof of concept, a real-world case is presented to demonstrate the feasibility of the selection diversity index.

“…The most-heavily loaded K lines are then removed. (A similar approach is taken in [107] and [108]) Elec_between This static metric of electrical betweeness was proposed in [109] (cf [45]). It uses the notion of unit transactions of power between each generator and each load, and sums each branch's involvement in the partial flows [110] that these transactions invoke.…”

“…We chose both the graph and the edge very carefully in this paper, but some of our logic might still be relevant to this larger problem. Considering the close relationship between the power grid and the Kuramoto model, this question might bear on current issues of power grid resilience [32][33][34][35][36][37].…”

Comparing the locking threshold for rings and chains of oscillators

We present a case study of how topology can affect synchronization. Specifically, we consider arrays of phase oscillators coupled in a ring or a chain topology. Each ring is perfectly matched to a chain with the same initial conditions and the same random natural frequencies. The only difference is their boundary conditions: periodic for a ring, and open for a chain. For both topologies, stable phase-locked states exist if and only if the spread or "width" of the natural frequencies is smaller than a critical value called the locking threshold (which depends on the boundary conditions and the particular realization of the frequencies). The central question is whether a ring synchronizes more readily than a chain. We show that it usually does, but not always. Rigorous bounds are derived for the ratio between the locking thresholds of a ring and its matched chain, for a variant of the Kuramoto model that also includes a wider family of models.
