Problems solved by technology
However, there are certain problems in this service calling method: First, because mobile users are always in a mobile state, their geographic location is difficult to predict
In addition, due to the distance limitation of wireless communication, once the user moves and the distance between the interacting parties exceeds the maximum limit of the communication distance of the mobile device, the interaction of this service will not be successfully executed
Therefore, in this mobile scenario, there will be certain risks in calling the service
However, in the traditional service composition method, because the mobility of mobile users is not considered, there is a great risk of execution failure in the execution of service composition.

Embodiment 1
[0053] Such as Figure 1 ~ Figure 3 As shown, the risk-avoiding mobile modeling method for mobile service combination provided by Embodiment 1 of the present invention includes: collecting mobile service provider mobile information; establishing a service provider mobile model according to the information provided by the service provider; The problem description of establishing service composition transforms the problem into a multi-objective optimization problem; the result of service composition is obtained by using the existing multi-objective optimization method to solve it.
[0054] In the risk-avoiding mobile modeling method for mobile service combination provided in Embodiment 1 of the present invention, the method for establishing a mobile model for a service provider includes:
[0055] The application scenario of the mobile model corresponds to an area within a certain range, which can be divided into several sub-areas. A region can be modeled as A={a 1 ,...,a n},i...

The invention discloses a risk-avoiding mobile modeling method oriented to mobile service combinations, which includes the following steps: 11) collecting mobile information of mobile service providers; 12) establishing mobile models of service providers according to information provided by mobile service providers ; 13) Establish a problem description of service combination according to user needs, and transform the problem description into a multi-objective optimization problem; 14) Use the multi-objective optimization method to obtain the service combination result, and the risk-avoiding mobile model for mobile service combination provided by the present invention, through Collect the mobile information of mobile users, establish a mobile model for mobile service providers, and then introduce the mobile model into the problem of service portfolio selection, thereby reducing the risk of mobile service portfolio execution and improving its service quality; thus overcoming the problem of only traditional Internet The method of combining services in the mobile environment cannot be directly applied to the mobile environment, so as to improve the execution success rate of service composition in the mobile environment.
Description
technical field [0001] The invention relates to the problem of service composition under the mobile environment, in particular to a risk-avoiding mobile modeling method oriented to mobile service composition. Background technique [0002] In recent years, with the rapid development of the mobile Internet and mobile intelligent terminals (smart phones, tablet computers, etc.), Web services are no longer limited by the traditional network environment, and services can be provided through mobile terminals, making the traditional service provision methods become Being more flexible also brings more challenges. Mobile users will use mobile terminals to call more complex service applications, that is, multiple services are organically combined to complete a complex task. Mobile users can directly realize service interaction through wireless network communication (Bluetooth, wireless local area network, near field communication, etc.) between terminals. This direct interaction can...
