    Marl

    Marl

    A hybrid thread / fiber task scheduler written in C++ 11

    ...Under the hood, fibers allow tasks to yield while waiting, keeping cores busy without blocking threads. The runtime is portable across platforms and integrates cleanly with real-time systems that must minimize latency jitter. Graphics, simulation, and media pipelines use marl to turn long serial phases into parallel stages without rewriting everything around coroutines.

    Minsky

    Minsky

    System dynamics program with additional features for economics

    Minsky brings system dynamics and monetary modelling to economics. Models are defined using flowcharts on a drawing canvas (as are Matlab's Simulink, Vensim, Stella, etc). Minsky's unique feature is the "Godley Table", which uses double entry bookkeeping to generate stock-flow consistent models of financial flows. Minsky is good for demonstrating mathematics too, with the most "math-like" interface in system dynamics. Sign up to Minsky's Patreon page (for as little as $1 a month) at...

    No-code system is for the visual creation of structural-functional models and the automatic generation of R language simulation models. The program can be used to describe information, production, organizational, and other processes. For graphical representation, the EdPM/EPM notation is used, which allowed us to implement: - structural-functional modeling using graphical methods; - the study of the efficiency of structural-functional models using simulation methods, that allow (e.g. unlike Petri nets) to process queries in groups, which is important for the study of the efficiency of using such methods as volumetric calendar planning and AI methods in process activities, since the operating time of these methods depends on the number of parameters and changes nonlinearly; - the study of multiprocess systems; - the results were obtained, that allow you to find efficient topologies of structural-functional models.

    BEDS - Bed Evaluation & Design System

    A system for designing and evaluating patient flow in hospitals.

    BEDS evaluates patient flow in hospitals. Specifically, BEDS evaluates the occupancy of beds and the probability of receiving a bed on arrival to the hospital. BEDS is built on the assumption that patients arrive with a stationary intensity, and that the distribution governing their length-of-stay is also stationary. Thus, BEDS works only when modeling inpatient wards. BEDS further assumes a setup consisting of a number of patient types and wards. The wards contain a fixed capacity....

    COVID-19 Scenarios

    Models of COVID-19 outbreak trajectories and hospital demand

    ...In particular, the initial case counts are often only rough estimates. The primary purpose of the tool is to explore the dynamics of COVID19 cases and the associated strain on the health care system in the near future. The outbreak is influenced by infection control measures such as school closures, lock-down etc. The effect of such measures can be included in the simulation by adjusting the mitigation parameters. Analogously, you can explore the effect of isolation on specific age groups in the column "Isolated" in the table on severity assumptions.
