In attended home delivery, the delivery time slot offering problem has a significant impact on the efficiency of the retailer providing this service. Since the decision on which time slots to offer is typically made online during the customer booking process, this problem requires a real-time...

In this paper, we introduce an integrated schedule of order picking and delivery for instant delivery. The schedule of order picking, including order batching and picking sequencing, is formulated considering order delivery by depicting orders' location dispersion. The online schedule of order...

Clinical laboratories play a key role in the delivery of healthcare services, as the result of clinical tests affect 70 percent of medical decisions. Therefore, to provide high quality services, small labs send some of their samples to a well-equipped central lab. The objective of this paper is...

In this paper, we investigate optimization of an aircraft maintenance routing problem (AMRP), which is currently a hot research topic in the air transport industry. The optimization of AMRP can help airline companies improve their management capacity and operational efficiency. However, there...

Conflict-Free Vehicle Routing Problems(CF-VRPs) arise in manufacturing, transportation and logistics facilities where Automated Guided Vehicles (AGVs) are utilized to move loads. Unlike Vehicle Routing Problems arising in distribution management, CF-VRPs explicitly consider the limited capacity...

Companies can gain significant advantages from the integrated optimization of production, inventory, and routing in a supply chain. The production routing problem (PRP), which aims to jointly optimize production, inventory, and vehicle routing, is motivated in this fashion. In actuality, the...

Most public facilities in the European countries, including France, Germany, and the UK, were built during the reconstruction projects between 1950 and 1980. Owing to the deteriorating state of such vital infrastructure has become relatively expensive in the recent decades. A significant part of...

This study investigates the periodic vehicle routing problem (PVRP) and its variant with time windows with a particular focus on alternative formulation approaches that can be solved by a state-of-the-art commercial solver. We propose a new vehicle flow formulation for the PVRP and strengthen it...

As satellite communications emerge, meeting the deadline requirement of data flow concentrates more on the trade-off between the route lengths and capacities, since the propagation delay becomes more outstanding in satellite networks.To deal with the transmission optimization problems of...
