The last-mile vehicle routing problem with delivery options

AbstractThe ongoing rise in e-commerce comes along with an increasing number of first-time delivery failures due to the absence of the customer at the delivery location. Failed deliveries result in rework which in turn has a large impact on the carriers’ delivery cost. In the classical vehicle routing problem (VRP) with time windows, each customer request has only one location and one time window describing where and when shipments need to be delivered. In contrast, we introduce and analyze the vehicle routing problem with delivery options (VRPDO), in which some requests can be shipped to alternative locations with possibly different time windows. Furthermore, customers may prefer some deli…
Fossil Fuel and Biofuel Boilers in Ukraine: Trends of Changes in Levelized Cost of Heat
2022
An increase in the share of renewables in heat supply systems is a promising direction to reach sustainable development goals and decarbonization. Decision makers should consider various factors, including energy market prices, the availability of biofuels, boiler and auxiliary equipment costs, logistic costs, and the taxation system. In the European Union, the energy crisis causes a rapid increase in fossil fuel prices. Moreover, the use of fossil fuels results in greenhouse gas emissions, which threatens the achievement of sustainable development goals. We studied the influence of the delivery cost and the value of environmental tax rates on the levelized cost of heat. Low-capacity boiler…

Last mile logistics is considered the most expensive part of the supply chain. This is due to the high cost of deliveries related to the costs of organizing the transport of small parcels to individual customers, including the costs of fuel, vehicle operation and couriers. Considering the growing popularity of e-commerce among citizens, the growing problem of the last mile of deliveries should be analysed. The study focuses on the analysis of the literature on the subject, as well as on the existing or possible solutions to issues related to deliveries to the end customer. The main aim of the study is to present the proposed solutions to the last mile problem in the light of possible benefi…
