Component Based Software Development at NLR: Assembling Aerospace Applications.

摘要

The classical approach to the production of software is to write a tailored solution dedicated to each application. For each new application the production process starts from scratch. This approach is becoming increasingly infeasible due to the commercial realities of unaffordable costs combined with an unaffordable time-to-market. Furthermore experience has shown that in general this labor intensive approach can not guarantee the application's quality, i.e. that the application performs its intended functions correctly. Re-use has been seen as a solution to some of these problems for a long time. Due to problems related with finding which modules to re-use, ambiguities in the documentation of the module's behavior combined with an unspecified and hence unknown reliability of the module, re-use has not achieved the success expected from it. Component based development is the latest attempt to improve the software production process on all of the three items mentioned.
