According to the theory on Dominance-based variable precision rough set,we study and program Matlab codes to compute the attribute reductions and realize the variable precision rough set in ordered information systems.While a single dominance decision is considered in an ordered information system,the forms of reductions are not affected by the consistence of the system.And the attribute reductions with respect to a single decision are considered in this paper.Furthermore,cases are employed to illustrate the corrective of the program.
