The flow diagram in Figure 29 shows the original layout of the receiving department of an aircratt factory. The path of movement of the goods from the point of delivery to the storage bins is shown by the broad line. The sequence of activities is one of unloading from the delivery truck cases containing aircraft parts (which are themselves packed individually in cartons), checking, inspecting, and marking them before putting them into store. These cases are slid down an inclined plane from the tail of the truck, slid across the floor to the "unpacking space" and there stacked one on top of another to await opening. They are then unstacked and the lid removed. The delivery notes are taken out and the cases are loaded one at a time on a hand truck, by which they are taken to the receiving bench. They are placed on the floor beside the bench. After a short delay they are unpacked, each piece is taken out of its carton and checked against the delivery note. It is then replaced in its carton; the cartons are replaced in the case and the case is moved to the other side of the receiving bench to await transport to the inspection bench. Here the case is again placed on the floor until the inspectors are ready for it. The parts are again unpacked, inspected, measured, and replaced as before. After a further short delay the case is transported to the marking bench. The parts are unpacked, numbered and repacked in the cartons and the case, after another delay is transported by hand truck to the stores and there placed in bins to await issue to the assembly shops. Required: (a) Prepare a flow process chart for the present method. (b) Develop a flow diagram for inspecting and marking incoming parts for the improved method
