Interface QueueLogic

All Known Implementing Classes:
MM1dLogic, MM1Logic, MMNdLogic, MMNLogic
public interface QueueLogic
This interface represent the logic of the queue types: the arrival and the execution of the process/job. This changed with respect to inputs arrival rate(lambda), service time, number of station capacity or number of servers. Each queue type could have different inputs.

  • Method Details

    • getStatusProbability

      double getStatusProbability(int status) throws NonErgodicException
      Calculates the probability of each status.
      Parameters:
      status - number of elements in the status
      Returns:
      the probability of the status
      Throws:
      NonErgodicException - if the operation cannot be completed

    • getRunTime

      double getRunTime()
      Calculates the service time of the job.(ms)
      Returns:
      service time

    • getArrivalTime

      double getArrivalTime() throws NoJobsException
      Calculates the arrival of the next job.(ms)
      Returns:
      interarrival time
      Throws:
      NoJobsException - if the operation cannot be completed

    • getMaxStates

      int getMaxStates() throws InfiniteBufferException
      Returns the maximum number of the jobs in the queue(only buffer)
      Returns:
      0 if the buffer is ideal(infinite), a positive number, otherwise
      Throws:
      InfiniteBufferException - if the operation cannot be completed

    • mediaJobs

      Throws:
      NonErgodicException

    • throughput

      double throughput() throws NonErgodicException
      Calculates the average throughput(X)
      Throws:
      NonErgodicException

    • responseTime

      double responseTime() throws NonErgodicException
      Calculates the average response time(R)
      Throws:
