This model uses @RISK to run a discrete-event simulation of insurance claims through time. It assumes that a company starts with an initial number of customers and an initial amount of cash. There are three types of events, and the times between each are assumed to be exponentially distributed. A type 1 event is when a customer makes a claim for a random amount, a type 2 event is when a current customer leaves the company, and a type 3 event is when a new customer joins the company. All of the company's customers pay a premium at a given daily rate.
