History

"Last mile" was originally used in the telecommunications industry to describe the difficulty of connecting end users' homes and businesses to the main telecommunication network. The last "mile" of cable or wire is only used by one customer. Therefore, the cost of installing and maintaining this infrastructure can only be amortized over one subscriber, compared to many customers in the main "trunks" of the network. In

the last mile describes a similar problem for transporting either people or freight. In freight networks, parcels can be delivered to a central hub efficiently via ship, train or other means, but they must then be loaded into smaller vehicles for delivery to individual customers. In transportation networks, "last mile" describes the rising marginal cost of getting people from a transportation hub such as an airport or train station to their final destination. In 2018,

or port, they must then be transported to their final destination. This last leg of the supply chain is often less efficient, comprising up to 53% of the total cost to move goods. This has become known as the "last mile problem". The last mile problem can also include the challenge of making deliveries in urban areas. Deliveries to retail stores, restaurants, and other merchants in a central business district often contribute to congestion and safety problems. A related last mile problem is the transportation of goods to areas in need of humanitarian relief. Aid supplies are sometimes able to reach a central transportation hub in an affected area but cannot be distributed due to damage caused by a natural disaster or a lack of infrastructure. One challenge faced in last-mile delivery is unattended packages. Shipping companies, like

in the United States has deployed lockers where customers can pick up packages rather than them being left at their home. This protects them from theft and damage as well as allowing companies to deliver to one location, rather than a number of individual homes or businesses. Similarly, in Taiwan, some online vendors offer the option of delivery to a convenience store of the customer's choice, for pickup from the store by the customer. Not only does this reduce the chance of theft and consolidate packages but also payment of the purchase at the store may also be offered. To reduce cost retailers have researched using autonomous vehicles to deliver packages. US-based

The last mile problem

The last mile problem refers to last mile being the most expensive stage of the entire logistics journey. In fact, it accounts for 53% of total delivery costs.

increases small-scale delivery expenses. * Customer expectations for rapid deliveries add pressure for costly express options. * Maintaining a skilled delivery workforce. * Rising fuel prices, vehicle maintenance. The last mile problem is exacerbated in rural areas due to dispersed populations and lower demand. The last mile problem is usually addressed by route optimization methods that lead to reduced mileage, fuel consumption and working hours. Businesses in the last mile sector can either optimize routes manually or use a delivery management technology platform.


Last mile technology platforms

Due in part to demand on retailers and product manufacturers to provide expedited (same and next day) deliveries, tech-enabled last mile technology platforms have emerged. Increased demand for last-mile fulfillment has put pressure on shippers to manage many types of delivery companies, which range from traditional parcel carriers to couriers, to on-demand service providers that execute an "
