Web Service intermediary (WSI): 這個角色就是composer.
問題:we consider the joint decision of location and pricing problem in a market of complementary Web services.
市場上有兩個Provider分別提供S1, S2, WSI可以把S1,S2組合成一個服務提供給使用者,
使用者選擇時可以直接向WSI請求合成服務, 也可以向Providers分別請求服務,自己合成.
從price+response time的角度來考慮.
對於WSI來說, Providers是它的競爭者, WSI要選取合適的location, 使得在競爭中具有價格和response time的優勢.
