1 EXERCISE 1 Cream, a producer of personal care products, needs to build a new storage system, made by single deep selective racks, served by counterbalanced forklift trucks. Assuming the following: - required storage capacity= 10,000 pallet locations; - maximum pallet load dimensions: 800 x 1,200 mm x h=1,500 mm; - pallet locations per bay = 2; - building available height = 9 m; - input/output point distributed along the storage front; - fixed length of the working aisle = 60 m; - width of the working aisle = 2.8 m; - width of the across aisle = 3 m; - upright width and beam height = 100 mm (both); - distance between upright and pallet load, between two pallet loads in the bay = 100 mm; - clearance between the top of the pallet and the above beam = 150 mm; - distance between two opposite pallet loads in the facing racks = 200 mm - horizontal speed of the truck = 2 m/s; - vertical speed of the forks (up and down) = 0.4 m/s; - maximum height reachable by the forks = 7.5 m; - fixed time for a single command cycle (fork cycle, positioning…) = 60 s, you are requested to: - design the storage system and determine the minimum number of trucks to provide 200 single command cycles/h, assuming the same probability to access each pallet location - determine the minimum number of trucks to provide 200 single command cycles/h, assuming to divide the storage system in two areas as reported in figure 1 and table 1 2 EXERCISE 2 Shoes S.p.A. is a small Italian company that manufactures and distributes shoes and accessories. Its picker to part low level picking system has a layout as shown in Figure 2, with 26 working aisles 12 m long. Pickers use a traversal routing policy and a batch sort-while-pick picking policy. Assume the following: - (average number of order lines)/batch = 40; -…
