All Implemented Interfaces:

public enum ImpatienceType
extends Enum<ImpatienceType>
implements Serializable

Constants for specifying customer impatience types. Impatience refers to customers leaving a queueing system without receiving service. The main types are: - RENEGING: Customer abandons after joining the queue (timer-based abandonment) - BALKING: Customer refuses to join based on queue state (queue-length or wait-time based) - RETRIAL: Customer moves to orbit and retries entry after a delay ID values match MATLAB ImpatienceType constants.

Enum Constant Details

RENEGING

public static final ImpatienceType RENEGING

Reneging - customer abandons the queue after waiting too long. This is the standard "impatience" where a job joins the queue but leaves before service if its patience time expires. Currently supported by JMT solver.

BALKING

public static final ImpatienceType BALKING

Balking - customer refuses to join the queue based on queue state. This occurs when a customer arrives but decides not to join based on factors like queue length or expected waiting time.

RETRIAL

public static final ImpatienceType RETRIAL

Retrial - customer moves to orbit and retries queue entry after a delay. This occurs when a customer is rejected due to capacity constraints and enters an "orbit" buffer, periodically attempting to re-enter. Supports both unlimited retries and configurable maximum attempts.

Method Details

values

public static ImpatienceType[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ImpatienceType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getID

public int getID()

Get the numeric ID for this impatience type. IDs match MATLAB ImpatienceType constants.

Returns:

numeric ID

fromID

public static ImpatienceType fromID(int id)

Convert numeric ID to ImpatienceType enum value.

Parameters:

id - numeric impatience type ID

Returns:

corresponding ImpatienceType enum value

Throws:

IllegalArgumentException - if ID is not recognized

toText

public static String toText(ImpatienceType type)

Convert ImpatienceType to human-readable text.

Parameters:

type - the impatience type

Returns:

text description
