How do transportation modes influence supply chain costs?

Transportation modes significantly influence supply chain costs primarily by impacting delivery speed, reliability, and shipping expenses. Each mode of transportation—whether it be air, road, rail, or sea—comes with its own set of characteristics that affect how and when goods reach their destination.

For example, air transportation is typically much faster than sea transport, which means that when time is a critical factor, businesses may opt for the higher shipping costs of air freight. On the other hand, shipping via sea is generally more cost-effective for transporting large volumes of goods but takes considerably longer. This decision affects inventory holding costs because if goods arrive later than expected, companies may need to hold larger inventories to meet customer demand, further driving up costs.

Moreover, reliability can also influence overall supply chain costs; for instance, if a shipping mode is prone to delays, companies may need to invest in buffer stocks or expedited shipping options, which can increase costs. Therefore, the choice of transportation mode is critical for managing expenses effectively within the supply chain, as it encompasses both the direct costs associated with shipping and the indirect costs arising from delays or shortages.

In contrast, the other options do not directly relate to how transportation modes influence supply chain costs. For example, determining supplier payment terms is more
