Cargo loading and planning is the most essential factor in transportation like railways, airlines, trucks and buses. It is the proper arrangement of goods, items or cargo into the available space of container. Due to improper arrangement of cargo and unavailability of proper optimization techniques the space gets wasted and damage of goods occurs in container. The proper arrangement and placement of the cargo is very difficult task today. To utilize the maximum occupancy of the container the optimization algorithms are required to design. The optimization algorithms, simple algorithm, LAFF (Largest Area First Fit) and LAFF algorithm with Weight consideration are proposed. All algorithms, simple algorithm, LAFF and LAFF with weight consider the dimensions of the cargo and container like base, height, width and weight. These algorithms help to plan and load cargo properly in a container and give the optimized solution for arrangement of cargo. Experimental evaluation shows that, our proposed algorithms give maximum space utilization than existing methods.
