Transportation Cost Matrix

Transportation Cost Matrix is a table that shows the costs of transporting goods from various sources (warehouses, plants, suppliers) to various destinations (retailers, customers, distribution centers). It helps in logistics decision-making, cost optimization, and route planning.

Structure of the Matrix:

Destination A Destination B Destination C
Warehouse 1 ₹500 ₹600 ₹550
Warehouse 2 ₹450 ₹620 ₹580
Warehouse 3 ₹480 ₹610 ₹540
  • Rows: Represent sources (e.g., factories, warehouses)

  • Columns: Represent destinations (e.g., cities, ports, customers)

  • Cells: Contain the transportation cost between the corresponding source and destination

Purpose Transportation Cost Matrix:

  1. Cost Optimization: Identify the lowest-cost path for delivering goods

  2. Decision Support: Helps managers choose the best warehouse-to-customer routes

  3. Resource Allocation: Efficiently allocate vehicles and logistics resources

  4. Scenario Analysis: Helps simulate changes in fuel price, routes, or distance

Applications of  Transportation Cost Matrix:

  • Cost Optimization

The transportation cost matrix enables businesses to compare costs across different routes and suppliers. By identifying the lowest-cost paths, companies can reduce total transportation expenses while maintaining service levels. This helps in planning deliveries economically and avoiding unnecessary expenses. Cost optimization becomes especially crucial in large-scale distribution networks where minor savings per shipment can lead to significant financial benefits.

  • Route Planning

A transportation cost matrix is essential for effective route planning. It helps logistics managers evaluate multiple delivery options and select the most cost-effective or time-efficient route. By analyzing matrix data, companies can minimize fuel consumption, improve delivery timeframes, and maximize vehicle utilization. This supports streamlined operations and consistent, on-time deliveries.

  • Network Design

In supply chain network design, the matrix helps determine ideal warehouse and distribution center locations by comparing transport costs from each source to various destinations. It supports decisions on whether to consolidate shipments, open new warehouses, or reroute deliveries. This results in a leaner, more responsive supply chain with optimized infrastructure.

  • Scenario Analysis

Companies use transportation cost matrices to run “what-if” scenarios, such as rising fuel prices, supplier changes, or weather disruptions. By modifying cost values in the matrix, they can anticipate the impact on total logistics cost and adjust their strategies proactively. This predictive capability enhances agility and preparedness in dynamic business environments.

Transportation Cost Matrix Example:

A company needs to transport goods from 3 warehouses (W1, W2, W3) to 4 distribution centers (D1, D2, D3, D4). The cost (in ₹ per unit) of transporting goods from each warehouse to each distribution center is shown below:

D1 D2 D3 D4
W1 ₹20 ₹24 ₹11 ₹25
W2 ₹28 ₹27 ₹82 ₹83
W3 ₹74 ₹97 ₹71 ₹96
  • Transporting goods from W1 to D3 costs ₹11 per unit — the lowest cost option.

  • Transporting from W2 to D3 or D4 is very expensive (₹82/₹83), so these routes are less favorable.

  • This matrix helps the logistics planner choose routes with the lowest cost and design optimal shipping plans.
