Web Service intermediary (WSI): 这个角色就是composer.
问题:we consider the joint decision of location and pricing problem in a market of complementary Web services.
市场上有两个Provider分别提供S1, S2, WSI可以把S1,S2组合成一个服务提供给用户,
用户选择时可以直接向WSI请求合成服务, 也可以向Providers分别请求服务,自己合成.
从price+response time的角度来考虑.
对于WSI来说, Providers是它的竞争者, WSI要选取合适的location, 使得在竞争中具有价格和response time的优势.
