Abstract: By considering $n$ components displayed on a structure (e.g., a steel plates), a Cox-type model for the hazard function is proposed which includes spatial dependency between components. The state (non-failed or failed) of each component is observed at some inspection times. From this data, we propose to use the SEM algorithm to estimate the parameters of the model. A study based on numerical simulation is then provided.
