A new method of finding component orthogonal arrays for order-of-addition experiments

The order-of-addition experiments aim at determining the optimal order ofmcomponents such that the yields are optimized. The component orthogonal array (COA) allows to economically find out the optimal order by testing some carefully selected orders from all of them! orders. This paper proposes a new method of finding COAs of broader run sizes. As an application of the new method, some COAs with 4, 5 and 6 components are tabulated. TheD-efficiencies of the COAs found by the new method are investigated under the pair-wise ordering model.
