Environment Template This UPPAAL SMC template represents an environmental model, named "Env". It uses a clock variable, "ec", to keep track of time within this environment. The template defines a function, "update()", that is used to update the environment. The function sets the clock "ec" back to zero, then adjusts a variable "eff" (which seems to represent some measure of effectiveness) according to certain conditions. If "eff" is greater than or equal to the product of 1 and the difference between 4 and another variable "adh", "eff" is decreased by the product of 1 and the difference between 4 and "adh". If "eff" is greater than 0 but does not meet the previous condition, "eff" is decreased by 1. If "eff" doesn't meet any of these conditions, it remains the same. The template includes a single location with an invariant condition that "ec" must be less than or equal to 9. This means that the system can remain in this location as long as the value of "ec" is less than or equal to 9. A self-loop transition is present in the template, with a guard condition that the transition occurs when "ec" is greater than or equal to 9. When this transition occurs, the "update()" function is called, thus resetting the clock and potentially adjusting "eff". Overall, this template seems to represent a periodic update of the "eff" variable, where the period is determined by the "ec" clock and influenced by the "adh" variable. This could model some sort of environmental influence on the effectiveness of a process.
Asthma Flare Template The template uses a clock variable "hc", possibly representing time spent in hospital. It also includes two functions, "light()" and "no_flare()", which return different values based on the state of a variable "p". This could be used to represent different rates of flare occurrences based on the patient's condition severity. The model includes four locations or states: NoFlare, Light, Serious, and Hospital. The initial state is NoFlare, as indicated by the "init" tag. The NoFlare location has an exponential rate label of "8*p". This could be used to represent the time until the next event (i.e., moving to a different state), with higher values of "p" leading to faster transitions. The Light and Serious locations are marked as urgent, which in UPPAAL means that time can't progress in these states, leading to immediate transitions to other states. The Hospital location has an invariant condition that "...
