Sustainable Solutions for SCM

The highest energy consumption is during the climb flight of a plane. For short distances of 1,500 km or less, the proportion of the energy consumption for the climb flight is much higher than compared to a transatlantic or transpacific flight. The shortest distance is generally taken for the calculation. In addition, 95 km are added for any planned or not planned actions during the transportation. In Table 6.10 the energy consumption for different distances is given for medium and long haul range.

The flight distance is 6,305 km. The energy consumption is: F = 0,1 t x (6,305 + 95) km x 0.147 kg/t km = 92.6 kg of kerosene. Warehouses still have an important role in a supply chain. They buffer imbalances in supply chains. Warehouses are installed upstream in a supply chain between suppliers and a producing company, as well as downstream between a retailer and the final customer. The typical tasks of a warehouse in a supply chain are: • Receiving goods. • Storing goods. • Dispatching goods. Warehouses are found at major logistics nodes like highways, airports, train stations and harbours. As in a lot of other logistics situations, a trade-off between delivery service and costs exists. Customers of consumer goods do not want to wait a couple of days for their products ordered from an online-retailer. They expect their delivery the next day. New concepts of retailers even offer same-day-delivery possibilities to customer. To handle this service level, the inventory of stock must be sufficient to meet customer demand. This could result in high inventory and large warehouses which are typical cost-drivers. Sometimes, high costs for storing products are necessary.
