[Thesis] two papers on service Combination Based on Integer Programming on CEC/eee

These two joint conferences are called "flagship conferences of the IEEE Computer Society Technical Committee on e-commerce", but they feel pretty watery. the two articles listed here have only four pages. They are not very good in terms of innovation, technology, and writing.

The author of this article participated in WS-challenge 2008. This four-page essay introduces the framework of their competition works.
1. the framework proposed in this paper uses the MIP method to solve a Service combination solution that meets functional (referred to as parameter matching) and non-functional requirements. (S3.2) briefly introduces MIP formulation for the Web service composition problem.
This formulation has some limitations that are not directly mentioned in the article:
(1) constraints only involves NFR in the target. Therefore, this article mainly uses the MIP Method to Solve the Service combination Problem Based on parameter matching.
(2) The NFR in the target only applies to the QoS attributes that can be added (such as cost and delay time)
(3) it seems that only the sequential composition model is targeted, and the general parallel/condition/loop structure is not discussed.

2. (S5) mentioned two future work items from the service provider's point of view.
(1) If some services appear in multiple solutions at the same time in the combined solutions generated by different service combinations, you can consider package and sell these services.
(2) For a service combination target, use k best solutionsAlgorithmFind out the best K solutions. If some services appear in multiple solutions at the same time, you can consider package and sell these services.
These two problems are more like data mining. The key is to have a real dataset.

Article 2
Time: 1.0 hours
Web service composition using integer programming-based models. Icebe 2005

The author mentioned in (s6) that this article is mainly inspired by liangzhao zeng04 (QoS-aware middleware for Web Services Composition) and has made a comparison:
(1 ). in zeng04, constraints and objective functions all involve quality dimension. in this article, objective functions do not include execution time. the author thinks this process is more natural. (blogger: this is not an innovation, but an unimportant difference in detail processing due to different ideas)
(2 ). capacity and load are added to the QoS model in this article. (blogger: I only introduced these two Qos attributes, but they are not related to the main content in the full text. Abstract: "The effect of service level and workload on QoS is already strated ", however, I have not found the two attributes in the Document)
(3) explains how to define the target function for the combination structure, and discusses common sequential, parallel, switch, and iterative structures. (blogger: I didn't see any discussion about switch and iterative in this article ).

In general, this paper has no nutritional value for me.
