Planning Models for Component-Based Software Offerings under Uncertain Operational Profiles

We present a modeling framework for allocating development or support effort among software components to meet a specified cost or reliability objective. The approach is based on knowledge of the linkage between the operational profile and the architecture of the system, but allows for uncertainty through the use of probability distributions to characterize usage. An approach based on stochastic optimization is presented to obtain efficient solutions to the allocation problem. Results are demonstrated when uncertain usage is characterized by a Dirichlet distribution.
