Calculate the correct number of laborers to balance with the lull's production rate and the total and unit cost required to move and distribute all the studs.
 

You have been tasked with determining the correct number of Laborer's to pair with a Lull to distribute 5,000 Metal Studs in a Multi-Floor building The studs come bundled 50 per pallet and you will use a lull to transport them from the laydown yard to the building site. From the laydown yard to the building, it is uphill for the first 175 feet and then level ground for the last 250 feet. Company safety policy limits the travel speed of equipment on site to 5 mph, but the lull will slow on the uphill segment to 2 mph. On the return trip, the full will not slow and will travel at 5 mph for the entire trip. You estimate that it takes 1.5 minutes to approach and pickup each pallet and it takes 1 minute to place each pallet for the laborers to distribute through the building. The efficiency of the lull is such that it works about 50 mins of each hour. The time for a laborer to carry, place, and return varies depending on where in the building footprint the studs are placed, but the average trip will take 4 minutes. A laborer can carry (5) Five Studs/trip. The efficiency of the laborers is such that they work about 45 mins of each hour. From the company files you have the following resource cost rates: Lull $32.00/hr Operator $42.12/hr (already burdened) Laborer $36.45/hr (already burdened) Having all the data you need, you sit down to calculate:
