A polishing apparatus is provided for optimizing a polishing profile in consideration of even such parameters as the temperature on the surface of an object to be polished, and the thickness of a polishing pad, in addition to a polished amount. The polishing apparatus for polishing the object to be polished under control of a control unit CU has at least two pressing sections, and comprises a top ring which can apply an arbitrary pressure to the object to be polished from each of the pressing sections, a measuring device IM for measuring a polished amount of the object to be polished, and a monitoring device SM for monitoring the object to be polished for a polishing condition. The control unit CU forces the polishing apparatus to polish the object to be polished in accordance with a simulation program for setting processing pressures required to optimize a polishing profile of the object to be polished to the top ring based on the output of the measuring device IM and the output of the monitoring device SM.
