It is good, as departure time, place of arrival refer to as the constraint condition for multiplying trip altogether, the data processing of path model and protocol model
It is that the mathematical formulae established to this path model and protocol model carries out data verification.
A further improvement of the present invention lies in that removing the LIST SERVER (DF) in traditional JADE Platform, only protect
Agent management system and the big module of message delivery system two have been stayed, entire analogue system operational paradigm is improved.
The present invention improves JADE platform.JADE (JavaAgent Development Framework) is one
Cover software development framework.Purpose is to develop Agent system and follows the intelligent agent application program of FIPA standard.
JADE platform written in Java is made of various Java packets, these software packages provide ready-made for application program
Function and abstract excuse, independent application program.In Agent system, communication is the key that progress problem solving, and each
Agent realizes the basis of cooperation purpose.Agent communication language (agent communication language, ACL) is a kind of
For expressing the description language of interaction message between Agent.It provides the tool exchanged between Agent, makes between Agent
It can be in communication with each other to which interaction is to achieve the purpose that Solve problems.ACLMessage class describe can agent it
Between the ACL message that swaps.It contains a set of attribute by FIPA norm-setting.
Agent communication language feature is as follows:
(a) one message of response is supported.It is standardized according to FIPA, the rule that a response message must be perfect by a set of tissue
It constitutes, for example, the suitable value of in-reply-to attribute setting, uses identical conversation-id etc..JADE passes through
CreateReply () method helper person of ACLMessage class completes this work.This method return one it is new
ACLMessage object, it is effectively responded to one of current message.
(b) it supports Java serializing and sends byte sequence.Perhaps, some application programs, which are benefited from, to be passed through
The content of ACLMessage transmits byte sequence.One it is typical using be exactly utilize the serializing of Java two agent it
Between transmit Java object.ACLMessage class support program person using setContentObject () and
GetContentObject () method transmits ACLMessage object, the two methods activate Base64 to encode automatically.
(c) ACL encoder.Under normal circumstances, agent never needs to the encoder for explicitly calling ACLMessage,
Because platform can be automatically completed.However, in some special circumstances, programmer should use StringACLCodec class to provide
Method come the parsing of ACL message and be encoded into character string (String) format.
(d) possess message template (Message Template) class, it is several that JADE behavior model allows an agent to execute
Parallel task.However any agent should have execution multiple while the ability of dialogue.Because the queue for receiving message is complete
Portion's agent behavior is shared, so to realize the queue access pattern based on pattern match.MessageTemplate class
Allow to construct the mode of matching ACL message.Programmer can be each ACLMessage attribute by using the method for this class
Create a mode.The mode that user can be specified with definition application, this mode inheritance MatchExpression connect
Mouthful, new match () method is provided, can be used for the pattern match stage.
It is a kind of based on the above-mentioned implementation methods for multiplying trip analogue system altogether for acting on behalf of cooperation interaction referring to Fig. 1 more, including with
Lower step:
Step 1: being pre-processed by the data of registering of the Poi to passenger Agent and driver Agent, wherein passenger Agent
It include longitude, latitude, arrival time, time departure and location information with the Poi of driver Agent data of registering, by A1Mould
One group of trip constraint is generated after block.
1 Poi of table registers data
According to longitude and latitude distance calculation formulaIt calculates
The distance between two places of distance l.Wherein WA, WB indicate that the latitude of A, B two o'clock, JA, JB indicate the longitude of A, B two o'clock, R table
Show earth radius, value is 6378137.0 meters.
Step 2: using constraint condition as A2The input of module, driver Agent generation multiply motivation, structural motive model altogether.
Motivation Model is described as Agent (departure time, the time of reaching, destination).Driver Agent (10:07,11:10, favorable to the people reputation
Print service society) passenger Agent (10:31,10:44, Tsinghua University).
Step 3: driver Agent will multiply motivation altogether and link up with multiple passenger Agent, and negotiation result is inputted A3Module
Form (path) Matching Model.The model is mainly used for the similar road by similarity search driver Agent and passenger Agent
Diameter.
There are two types of basic class for similarity:
(1) objective similarity, i.e. similarity between object are certain functional relations between the multidimensional characteristic of object, than
Such as the Euclidean distance between object；
(2) subjective similarity, i.e. similarity is cognition relationship of the people to research object.
The present invention uses objective similarity.Consumed time cost M in driver's Agent unit distance is calculated first,
Next calculates separately out passenger Agent consumed time cost n in unit distance1、n2、n3, it is then added to obtain N, most
After calculate M/N, resulting value is similarity size.
Step 4: the driver Agent and passenger Agent for meeting route matching model are multiplied negotiation altogether, pass through modules A4It is raw
At protocol model.The content of negotiation mainly includes driver Agent and passenger's Agent departure time and arrival time.
Multiplying in the stage altogether, acted on behalf of driver and passenger as one, only when two desired strokes of agency are opened
Beginning the time can be with universal time coordinated, and negotiation can just succeed.
Step 5: using AMS optimization module A5, to obtain the Motivation Model of driver Agent and passenger Agent, path
With model, protocol model.Wherein, optimization refers to that AMS (agent management system) is responsible for access of the supervision and management to Agent platform
With the Agent used, retain Agent identifier catalogue (AID) and Agent status information.
Step 6: in JADE platform, AMS generates driver by Motivation Model, route matching model and protocol model
Multiply system altogether between Agent and passenger Agent.In the operation of entire analogue system, the interaction between more agencies is logical
Cross message delivery system (MTS) completion.
