cutting the percentage use of superior materials and conserving on expenditures for TQM$/$Six Sigma quality controls at each of the company's production locations where $500$ models are going to be produced in order to help offset the $$15$ million in annual production run setup costs for $500$ model$/$styles$.$

instituting production improvement option D at all production locations where $500$ models are to be produced; the use of robot$-$assisted production of $500$ models will boost the S$/$Q rating of the branded pairs being produced and also eliminate any increase in reject rates associated with producing $500$ models.

instituting production improvement options A and D at each of the production locations where $500$ models$/$styles are going to be produced.

concentrating all production of $500$ models at newly$-$established production locations in Europe$-$Africa and Latin America.
