This study investigates the issue of developing efficient knowledge reduction methods for real decision formal contexts. A corresponding heuristic algorithm is proposed and some numerical experiments are conducted to assess its efficiency. \itemrv{~} \itemcc{} \itemut{} \itemli{doi:10.1007/978-3-642-32115-3\_36} \end
