8、on high cube items high variety SKUs medium throughput,9,Palletised storage systems :Block Storage,Features : unit load placed directly onto floor limited depth - 6 plts deep,- back to back 2x6 often used with counter balance - narrow chassis single product per line- limited SKUs large holding Advan

9、tages : no capital equipment required high floor utilisation 55% simplified management can use random access Disadvantages : limited stacking height 3-4 plts, - post pallets, converters difficult to achieve First In First Out (LIFO) limited access to pallets / greater need for double handling typica
