Determine a mixed-model sequence that will efficiently meet

As local developers prepare for an increase in housing starts, they must anticipate their demand for various materials. One such material is tile. Used in bathrooms, kitchens, and for decoration, tiles come in many shapes, colors, and sizes. In order to accommodate the varying needs, the tile manufacturer must schedule its production efficiently. Each month developers order 30,000 boxes of quarry tile, 15,000 boxes of Italian mosaic tile, and 45,000 boxes of 4-inch bathroom tile. Determine a mixed-model sequence that will efficiently meet these needs. Assume 30 days per month.
