Answer 1

QUESTION 1 :

Solution 1:

There are types of simulation models . the simulation model in which the result of one trial does not affect the subsequent trial is referred as Discrete - event simulation model.

static simulation model : it is used to represent a system in which time plays no roles i.e. we are generating the statistical result by dwawing some random samples.

Dynamic simulation model: it analazing manufacturing and services and service system since the operate over time. it includes the passage of time. it looks at state changes as they occure over time.

Discrete - event simulation models : it proceed sequence of event changes at decrete point in time as triggered by events. such events occure at a particular instant in time and mark a change of state in the system.

Continious - event simulation model : its behaviour changes only in response to specific event and typically model changes to a system resulting finite number of event distributed over time.
