Two kinds of software-testing management problems are considered: testing-resource allocation to best use specified testing resources during module testing, and a testing-resource control problem concerning how to spend the allocated amount of testing-resource expenditures during it. A software reliability growth model based on a nonhomogeneous Poisson process is introduced. The model describes the time-dependent behavior of software errors detected and testing-resource expenditures spent during the testing. The optimal allocation and control of testing resources among software modules can improve reliability and shorten the testing stage. Based on the model, numerical examples of these two software testing management problems are presented.

TVM 400 is a range of ATC systems built around the same basic architecture with a consistent set of hardware and software modules. System modularity ensures compatibility: the same rolling stock can be used under different operating conditions and with different signalling equipment. The flexibility of the system permits functional (safety and speed increase, etc.) and technical (new transmission channels) improvements. TVM 400 is an open system that can fulfil from the simplest to the most sophisticated needs in train operation requirements, from speed monitoring with or without wayside signalling to fully automated operation.
