In this paper, emphasis has been given to both the expected number of runs and the expected number of incorrect decisions and two stage group-screening designs have been obtained which minimise one fixing the other or minimise some sort of cost function which connects the two. Some group-screening plans have been given at the end as illustrations.
Keywords: group-screening plans, orthogonal main-effect plans, group-factor
