The product structure diagram for an assembly is shown below (numbers in parentheses indicate the quantity of part for each assembly). Each eight-hour day the assembly line produces 400 units. Because the assembly line is located in a different area of the plant than the areas where the parts A, B, and C are produced, a two-card ( C and P ) pull system is used. Information about producing and moving the three parts is shown in the following (all times in hours): If a safety margin of 20% is to be maintained, how many each of conveyance and production cards are needed for each of the three kinds of parts? Draw a schematic diagram showing the assembly and parts production areas, and the location of containers and cards
