A flexible manufacturing system which includes a stack yard, a machine tool and a stacker crane. In the stack yard, a pallet group, formed by stacking a number of pellets, is stored. The pallet group is transferred to a machine tool cell by the stacker crane. Each pallet has a memory, and data of the pallet itself and the member loaded on the pallet are memorized by the pallet. There are various kinds of members such as work-piece, tool and chuck jaw. These members are stored on exclusive pallets made for each kind of the member. Of the members, each tool and chuck jaw has its own memory and memorizes its own data. The data of all the memory can be read and written; therefore, the position of the pallet, tool and chuck jaw can be controlled at all times.
