In particular, we use modular systems theory to examine how different types of coupling impact the … over a 4-year period.We find that applications with higher levels of coupling cost more to maintain, are less likely to be … retired, and are less likely to be commissioned. However, we show specific types of coupling present greater challenges than …

First, we present a maximum likelihood approach … to define and evaluate a model validation metric. The advantage of this approach is it is more easily applied to …
