Transportation, electric, and communication networks are clearly common applications of Network Optimization. These types of problems can be viewed as minimizing transportation problems.
Keeping production costs low by producing or sourcing raw goods in other countries or states allows companies to make more profit, but the logistical costs of transporting and storing products can eat into those profits.
Business owners can benefit from understanding logistics, and the detailed costs involved, to maximize their margins and minimize costs. Logistics Logistics is defined as the management process for the movement of goods across country or across the globe. Companies map out the transportation path of their goods into a supply chain, or a path of transport that they use repeatedly to have goods shipped to them or to customers.
When goods travel, they are moved using a combination of travel methods that includes ships, trucks, trains and airplanes.
Companies use logistics to manage the timing and location of their goods in transport as a component of their overall supply chain management.
Managing Logistics Costs Companies need to manage their logistics with a balance between cost and performance, since the lowest-cost transportation path is not necessarily the fastest.

Logistics costs relate to the charges for various transportation methods, including train travel, trucks, air travel and ocean transport. Additional logistics costs include fuel, warehousing space, packaging, security, materials handling, tariffs and duties.
Logistics Planning Many companies plan out the logistics for their supply chain using diagrams resembling flowcharts, or software that can diagram and simulate the supply chain.
This helps work through each phase of the goods' journey through the supply chain to calculate the time and related logistical costs for various sections of the shipments' travel. Considerations Logistics is a complex discipline with several different fields of emphasis, including procurement logistics, distribution logistics and production logistics.
Every company has its own unique supply chain, with highly individualized logistics costs. Many companies employ logisticians to apply professional knowledge to the ongoing challenges of optimizing the logistics within a supply chain.
Their goal is to enforce a steady flow of goods or materials through their network of transportation links and storage points, or nodes, in the most efficient and cost effective manner.
They also plan for emergencies, such as production delays or specialized parts or equipment transport that are urgently needed to prevent incidents such as a shipping delay, telecommunications failure or grounded airplane.

Gaffney holds a Bachelor of Science in finance and business economics from the University of Southern California.Least Cost Method Definition: The Least Cost Method is another method used to obtain the initial feasible solution for the transportation problem.
Here, the allocation begins with the cell which has the minimum cost.
The lower cost cells are chosen over the higher-cost cell with the objective to have the least cost of transportation. Journal. Figure 2. Coal transportation network.
The main objective of the problem is the minimization of purchase and transportation cost. The detailed. The transportation cost incurred varies with the mode of transportation chosen and the particular mode chosen depends on the characteristics of the mode and the company’s need.
In Nigeria, roads are the dominant mode of transportation as it accounts for about 90% of the internal movement of passenger and freight (Oni, ). Table describes a cost minimization transportation problem. Table Supply | 3 | 5 | 4 | 6 | 5 | 8 Demand (a) Use the northwest corner rule to get an initial feasible solution.
(b) Solve using the MODI solution method.
14) The transportation algorithm can be used to solve both minimization problems and maximization problems. 15) Assignment problems involve determining the most efficient assignment of people to projects, salesmen to territories, contracts to bidders, and so on. The Vogel Approximation Method is an improved version of the Minimum Cell Cost Method and the Northwest Corner Method that in general produces better initial basic feasible solution, which are understood as basic feasible solutions that report a smaller value in the objective (minimization) function of a balanced Transportation Problem (sum of the supply = sum of the demand). NEW ALTERNATE METHODS OF TRANSPORTATION PROBLEM Introduction indicated the transportation cost transporting from source to destination and Sink also use these two methods for unbalanced transportation problem for minimization and maximization case.
Transportation cost data from the peak period in the year under study were analyzed and linear programming methods were employed in finding the routes that will optimize total transportation cost of .
