A new algorithm for obtaining mixed-level orthogonal and nearly-orthogonal arrays

Orthogonal arrays are frequently used in industrial experiments for quality and productivity improvement. Due to run-size constraints and level combinations, an orthogonal array may not exist, in which case a nearly-orthogonal array can be used. Orthogonal and nearly-orthogonal arrays can be difficult to find. This project will introduce a new algorithm for the construction of orthogonal arrays and nearly-orthogonal arrays with desirable statistical properties, and compare the new algorithm to a preexisting algorithm.
