Artificial Intelligent (AI) techniques make a great influence on real-world distribution operations due to the complexity and the difficulty of finding an optimal solution within the limited time frame. To bridge the gap between standard problems in distribution and the real world problems, in this research, the standard VRP problem is extended to Multi Depot Vehicle Routing Problem with Time W...

In this paper, we present a methodology for solving a multi-product, multi-depot periodic vehicle routing problem. The problem focuses on allocating products and assigning appropriate delivery days to a set of customers, and designing a set of delivery routes for every day of the planning period. A tabu-search based heuristic is proposed to find the best allocation and routing plan that would g...

Beef is a perishable product and requires special handling. Demand for beef also fluctuates quite high heavily influenced by various religious events traditions in Indonesia. Under these conditions, reasons, products are returned from customers to distributors. An increase the number of leads costs risk damage. The research created an optimization model distribution recall with minimal risks. a...

in this paper, the capacitated location-routing problem with fuzzy demands (clrp-fd) is considered. the clrp-fd is composed of two well-known problems: facility location problem and vehicle routing problem. the problem has many real-life applications of which some have been addressed in the literature such as management of hazardous wastes and food and drink distribution. in clrp-fd, a set of c...

This paper introduces a novel variant of the cumulative vehicle routing problem (CCVRP) that deals with home health care (HHC) logistics. It includes multiple nonfixed depots and emergency trips from patients to closest depot. The aim is minimize system's delayed latency by satisfying mandatory visit times. Delayed corresponds caregivers' total overtime hours worked while visiting patients. A n...

The Multi Trip Vehicle Routing Problem with Time Windows and Release Dates is a variant of the Multi Trip Vehicle Routing Problem where a time windows is associated with each customer and a release date is associated with each merchandise to be delivered at a certain client. The release date represents the moment the merchandise becomes available at the depot for final delivery. The problem is ...
