Warehousing basically involved two types of activities, inbound and outbound operations. Inbound activities consist of sourcing, expediting, receiving and storage while outbound activates involve picking, checking, packing, and transportation. Outbound processes are more work concentrated than inbound process, particularly order picking is the most labor-intensive work because for each SKU the picker have to travel to the storage location to retrieve the goods.
In transportation, there are different modes of transport by Air, Sea, and Land. Air transport is the fastest and most efficient method of transportation used by many companies. However, being the fastest and highest efficiency, it is also considered costlier compared to the other mode of transport.
Sea transportation has the largest carrying capacity that is suitable for carrying bulky cargo over long distances. Although sea transportation will take a longer time to reach the destination, but the cost is lower and more affordable compared to Airfreight.
