System An average of customers arrive each hour; interarrival times are exponential. Customers must complete three types of service before leaving the system. The first server takes an average of seconds exponentially distributed to perform type service. After waiting in line, each customer obtains type service exponentially distributed with a mean of minute from a single server. After completing type service, a customer will go to obtain type service exponentially distributed with a mean of secnds from a single server. After completing type service, a customer leaves the system. System The arrival process for system is identical to the interarrival process for system In system a customer must complete only one type of service. Service time averages minutes and is exponentially distributed. Three servers are available. In which system does a typical customer spend less time? Please justify your answer with your step by step analysis results.
