For own improved storage, compute the total cubiccapacity by multiplying the net storage space (SQ FT)by an average stacking height of 10 feet. Rememberthat stacking height may vary depending on thecharacteristics of the material.For unimproved open storage, multiply the squarefeet occupied by the representative stacking height.ATTAINABLE CUBIC FEETThe attainable cubic feet is the product of netstorage space (SQ FT) multiplied by the stacking heightpermitted by safety regulations and floor loadlimitations with the use of MHE. Therefore, theattainable cubic feet represents the cubic space usableor available for storage with existing resources asshown in figure 2-8.For determining the attainable cubic feet forimproved open storage, use the same formula as cubicspace capacity.BIN CUBIC CAPACITYThe cubic capacity of the bin is computed bymultiplying the length by the width by the height of itsoutside dimensions. The unused cubic space above thebin will not be included as attainable space.RACK CUBIC CAPACITYThe cubic capacity of the rack is computed bymultiplying the outside dimensions of the length by thewidth by the height. The cubic space above the rack isincluded to the extent permissible by safety regulations.OCCUPIED SQUARE FEETThe occupied square feet is the area occupied bybins, racks, and materials in covered or open bulk areas.The bin and rack space is considered occupied whetheror not material is stored therein. To determine theoccupied area (SQ FT), multiply the length by thewidth.OCCUPIED CUBIC FEETDetermine the occupied cubic feet by multiplyingthe net square feet by actual storage height(s).Compute the bin and rack occupancy bydetermining the vacant cubic feet portion and subtractit from the attainable cubic feet.OCCUPIED NET STORAGE SPACEThe simpler method of determining the occupiednet storage space is by computing the total vacant spaceand subtracting it from the total net storage space.Computing the actual vacant space is easier thanmeasuring the space actually occupied. To compute thevacant space, measure the floor area that is not actuallyoccupied by material. Include the space occupied byempty pallets and dunnage as vacant space.POTENTIAL VACANT SPACEThe two types of potential vacant space are type Aand type B. Type A is short spaces or broken spaces infront of stacks that cannot be used for storing suppliesother than identical sires, lots, and so forth. Type Avacant space is usually the result of honeycombing orpoor warehousing. Type B is low stacking that iscaused by failing to stack material to the full permissibleheight. The following factors are not considered aspotential vacant space: low stacking caused by floorload limitations, the height of roof rafters and ceilingjoists, and commodity characteristics.STORAGE OPERATIONSThe basic storage operations involve receiving,storing, and shipping of materials. An effective supplysystem greatly depends on the smooth flow of materialand paperwork from these operations.RECEIVINGQuick and accurate processing of receipts directlycontributes to an effective supply system. Receivingoperations are directly influenced by several factors.These include the type of materials to be handled,distance to storage locations, type of MHE available,and characteristics of the storage facility. Theprinciples of receiving is basically the same. Theincoming material is received, processed, anddistributed. Some incoming material requires specialhandling and control. These include materials that areclassified as pilferable or sensitive (including smallarms).
