public class LFTM_Service
extends Service

This class models a service offered in a P2P, Ad-hoc or Wireless Sensor Network, or even an agent in a multi-agent system. Its several attributes (price, quality, deliveryTime, etc.) are defined through fuzzy sets (Variables)

Constructor Detail

LFTM_Service

public LFTM_Service(Service service,
                    java.util.Collection<LinguisticTerm> linguisticTerms,
                    java.lang.String fuzzyPrice,

                    java.lang.String fuzzyDelivery,
                    java.lang.String fuzzyQuality)

Class LFTM_Service constructor

Parameters:

service - Service to "fuzzify"

linguisticTerms - Set of linguistic terms applied in the fuzzy sets representing this service attributes (price, quality, etc.)

fuzzyPrice - Price fuzzy value ("Very High", "High", etc.)

fuzzyCost - Cost fuzzy value ("Very High", "High", etc.)

fuzzyDelivery - Delivery time fuzzy value ("Very High", "High", etc.)

fuzzyQuality - Quality fuzzy value ("Very High", "High", etc.)

LFTM_Service

public LFTM_Service(java.lang.String id,
                    Variable price,
                    Variable cost,
                    Variable delivery,
                    Variable quality)

Class LFTM_Service constructor

Parameters:

id - Services's identifier

price - Fuzzy set representing the price of this service

cost - Fuzzy set representing the cost of this service

delivery - Fuzzy set representing the delivery time of this service

quality - Fuzzy set representing the quality of this service

Method Detail

compareTo

public Variable compareTo(LFTM_Service service,
                          double prizeWeight,
                          double costWeight,
                          double deliveryWeight,
                          double qualityWeight)

This method compares two services, by comparing their attributes and returns a fuzzy set representing such comparison. Each attribute is weighted with a given weight. If service1.compareTo(service2) output is, for instance, "Very High", it means that "service1 is much better than service2"

Parameters:

service - Service to be compared with this service

prizeWeight - Price weight

costWeight - Cost weight

deliveryWeight - Delivery time weight

qualityWeight - Quality weight

Returns:

A fuzzy set representing the comparison between this service and the given one

clone

public Service clone()

Overrides:

clone in class Service

Returns:

A copy a this service

get_price

This method returns the service's price fuzzy set

Returns:

The service's price fuzzy set

get_cost

public Variable get_cost()

This method returns the service's cost fuzzy set

Returns:

The service's cost fuzzy set

get_delivery

public Variable get_delivery()

This method returns the service's delivery time fuzzy set

Returns:

The service's delivery time fuzzy set

get_quality

public Variable get_quality()

This method returns the service's quality fuzzy set

Returns:
