= Nelson complexity index
{wiki=Nelson_complexity_index}
The Nelson Complexity Index (NCI) is a numerical measure used in the field of process engineering, particularly in the context of evaluating and ranking the complexity of refinery configurations. Developed by Dr. Robert Nelson, the index is primarily used to assess the complexity of refining processes based on the range of conversion capacities and types of processes included within a refining operation. The NCI is derived from the types of equipment and processing capabilities present in a refinery.
