It in the described emulator system model of setting up by algorithm for design.To compare by the data dispatching in Master Control Center design-calculated operation result (dynamic data of computing in the Master Control Center) and the emulator (being the data that static data is concentrated), if the re-set target of not meeting, then carry out the correction of System Discrimination type, till the output that generates data fit real data system by emulator.
Simulation result among Fig. 1 and re-set target refer to is meant that respectively the result in the controlling schemes that result that the genetic algorithm optimization by the fuzzy rule that embeds generates and practical problems require compares, usually adopt least square method that the data in the system model are revised, thereby model optimization algorithm among Fig. 1 is adjusted.Adjust back output and optimize the parameter of result's (satisfying objective function optimal value f (x), average, maximal value, superior rate), realize training and adjustment algorithm in the Master Control Center by intersecting parameters such as the factor and mutagenic factor as Master Control Center.The selection and the design itself of described embedding rules optimization of fuzzy method have embodied adaptive processing procedure.
Below in conjunction with the city logistics delivery system in detail concrete application of the present invention is described in detail, the information flow of dynamic data self-adaptive processing control mainly comprises following several core link in the path optimization's scheduling of promptly providing and delivering.The information flow of following algorithm for design is the key component of system.
To shown in Figure 4, the design core of described city logistics delivery system is the solution of the dynamically optimized scheduling problem of LRP as Fig. 3.The work that the scheduler program of its core will be finished in the dynamic data infosystem of city logistics delivery system has: the data of calling in according to control program select delivery home-delivery center, choose vehicle, prestowage vehicle, arrange the time of departure and select traffic route.If all home-delivery centers are regarded as potential facility, and actual road virtual is become traffic route, this scheduler program is exactly in fact an optimizing process that has the LRP of time restriction.The specific implementation of city logistics delivery system varies, this mainly is by professional self the location decision of dispensing, client such as service is enterprise or ordinarily resident, the goods of dispensing is the single relatively bulky goods of kind or short run goods various in style or the like, and these all will influence the specific implementation of its infosystem.But the LRP optimization method as its core is constant, and it has very big stability.Each logistics distribution system all will relate to decision processes such as addressing, arrangement route.Join on time under the prerequisite of goods satisfied by the method that the present invention proposes, not only controlled the cost of logistics distribution, also satisfied simultaneously client's demand, therefore the adaptive processing method that proposes of the present invention is effectively, and this method can promote the use of in the production reality in other field of Optimization Dispatching.
Reasonably city logistics dispensing scheduling should be satisfied following three targets: 1. transportation on time, and promptly the goods time period is on request transported in client's hand; 2. total cost (comprise the haulage track cost, set up and the fixed cost in operation warehouse, obtain means of transport cost etc.) minimum; 3. the vehicle transport total path is the shortest.
In order to solve these problems of city logistics dispensing, the present invention is on the abstract single goal LRP model basis of the LRP of forefathers' research, foundation meets the logistics distribution Model for Multi-Objective Optimization, and adopts heuritic approach and genetic algorithm, from multi-level solution city logistics dispensing Optimization Dispatching design problem.It mainly is to propose at the problem that the location of the facility in the logistics activity, traffic route are arranged.
As Fig. 2 and shown in Figure 5, this logistics distribution system input customer order information is to customer information processing module (not shown), and carry out wavelet analysis by filtrator, finish pre-service to the customer order original input data, and deposit pretreated data in dynamic data set with unified format, operation after being convenient to.This dynamic data concentrates the data that comprise to have: the client connects ETCD estimated time of commencing discharging, place, assortment of article, quantity etc., and these data deposit in along with each customer order, and all these dynamic datas also are kept at the Business Information data centralization as historical summary.
Concentrate regular good data to call in Master Control Center dynamic data then, this Master Control Center is also accepted the data from the static data collection simultaneously.This static data centralized stores be the data that seldom change, position, the number of vehicles of each home-delivery center, type, delivered payload capability as home-delivery center, information such as the numeral of transport routes, Customer Location, these information are not forever constant, and much smaller with respect to the frequency of its change of dynamic data.After this Master Control Center receives static and dynamic data, begin to start dispensing path optimization dispatching algorithm, and set up model bank by the processing rule in the controller based on the distribution network of the genetic algorithm of fuzzy rule, simultaneously the prior model in the emulator is compared, then export result of calculation if meet re-set target; If do not meet then, thereby realize scheduling to constraint conditions such as dispensing delivery period, transportation cost by the further correction model of system model correction identifier.Described result of calculation is the decision information of relevant goods delivery, this decision information mainly be included in which or which home-delivery center arrange cargo transport, which car cargo transport of each home-delivery center, each car load which client goods, dress what, when dispatch a car, the traffic route of each car etc.
This Master Control Center is issued corresponding home-delivery center to these decision informations, instructs home-delivery center to arrange the goods delivery business.Simultaneously, Master Control Center is passed to the customer information processing module to information such as partial data such as acknowledgement of orders, vehicle time of arrival, condition of loadings, and module becomes these information translation friendly form to pass to the client thus.Also to mail to the Business Information data set to these decision informations in addition, preserve as historical summary.
The present invention is on the operating mechanism basis of static scheduling system, proposition is based on the multiple-objection optimization dispatching system of the Adaptive Identification type of intelligent algorithm, both guaranteed the optimal selection of scheduling scheme, can obtain scheduling scheme again, determine the characteristic of real system, as dispensing delivery period, transportation cost according to practical problems, offer emulator and realize accurately simulation real system, by introducing identifier, as the self-correcting controlling mechanism, the slow variation of the dynamic data of adaption object characteristic; In addition, the present invention is in system's input raw data stage, through the pre-service of filtrator realization to real data, self-adaptive controlled by reference making mechanism, but the slow variation of adaption object characteristic.
