Service-correlation aware service selection for composite service
This is a paper on the "service computing" album of the Computer journal.

The problems to be solved in this article are clear:
WS are not independent. The choice of one ws will affect the QoS of the other. In the previous studies, we assumed that QoS is independent between Ws.
This article mainly solves the problem of combining multiple QoS constraints after the service-related QoS is introduced.

Contributions of this article include:
(1) A QoS description model and ing model supporting service association are proposed.
(2) generate the QoS description associated with the serviceAlgorithm(Service Association ing is input as a parameter)
(3) Two combined service selection methods supporting service association are proposed. One is Based on Integer Programming, and the other is a heuristic algorithm.
The Zeng method is used to model Web Service combinations.

In this article, QoS associated with services is related to specific functions of related services.
Rather than the Association caused by reasons at the technical level.
In order to describe the Association caused by this business level, the author divides the service description into attribute description and supported QoS description.
Attribute descriptionIt refers to the nature of the service. For example, for a ticket booking service, the attributes can include airlines and specified accounts.
QoS descriptionResponse time, price, etc.
Describes the value of QoS through the relationship between attributes and QoS of different services, in the form of value <-- precondition
