Abstract:
1. A computerized method for retrieving and processing data to provide dependency and root cause information for a process, comprising: receiving data corresponding to a historic performance of the process; detecting temporal dependencies and precedence tasks in the process from the historic data, wherein the temporal dependency is a dependency among tasks that are related through time constraint; generating historic dependency data; aggregating the historic dependency data into a probabilistic precedence network (PPN), the PPN including a complete set of all possible temporal dependency relationships reflected in the historic data; pruning the PPN by removing dependencies that occur a minimum number of times based on the historic dependency data, wherein the minimum number of times is a predefined minimum threshold value; identifying, from tasks that maintained a dependency in the pruned PPN, tasks that have had at least one of a delay or variance above a defined threshold based on the historic data; determining, from the tasks that have had at least one of a delay or variance above a defined threshold, tasks that have had a failure or a delay from one or more of the following: rework, repair, part shortage, and operator request for parts; identifying the tasks that have had a failure or a delay from one or more of the following: rework, repair, part shortage, and operator request for parts as a root cause for delay; and presenting results to a user.
