In this paper we presented two algorithms applied to select COTS components witth optimization of cost and data redunancy (size). The proposed algorithms are realized based on .NET platform and experimented on case study Geographic Translator Service. The comparison between proposed and original algorithm also is presented. | ’ Tap ch´ Tin hoc v` Diˆu khiˆn hoc, T.23, S.2 (2007), 153–163 ı e e . . a ` . ’ ´ ´ ´ ˆ ` ` ˆ ˆ .

Component-based software development is gaining recognition as the key technology for the construction of high-quality, evolvable and large software systems in timely and affordable manners. Commercial components (COTS) is being used more and more in Component-Based Software Engineering for building software applications, and accordingly, some mechanisms are demanded by developers of software applications to describe, search, select and compose COTS components. In this paper we presented two algorithms applied to select COTS components witth optimization of cost and data redunancy (size). The proposed algorithms are realized based on .NET platform and experimented on case study Geographic Translator Service. The comparison between proposed and original algorithm also is presented. ´ ’ ` ` ` T´m t˘t.
