How do i model a multi state system (a machine having many states: working, failed, not working well) using...
I am trying to model a machine having many states, similar to a Markov chain, but the transition between the states are random variables, (time to shift from a state to another). I am trying to do it on python using simpy but I am lost honestly.
if anyone uses simpy and have an idea on how to proceed, I would be thankful !
thank you in advance,

So you want your machine to randomly change between the states and then stay in that particular state for some time (also random or does each state have a specific timeout time?)? Maybe something like the code below would work for you? You assign a number to each state (state_dic) and a timeout time for each state (state_time_dic, this could also be an random number), and then in the function you see that the variable i is generated randomly. You could go through that loop as often you like.
state_dic= {1: "state 1", 2: "state 2", 3: "state 3"}
state_time_dic = {"state 1": 5, "state 2": 10, "state 3": 8}
def mulit_state_system(resource):
i = random.randint(1,4)
if i in state_dic.keys:
state = state_dic[i]
with resource.request as req:
yield req
yield timeout(state_time_dic[state])
I did not test the code. It's just to give you an idea.
