Magline Discusses Model and Algorithm for Courier Delivery Uncertainty in Delivering Excellence
Standish, MI, May 06, 2015 –(PR.com)– This week’s Delivering Excellence, sponsored by Magline reported that academics are attempting to solve a problem. “A Model and Algorithm for the Courier Delivery Problem with Uncertainty” was the work of Sungura, Rena Ord´o˜neza, Dessoukya, and Zhongb, part of Industrial and Systems Engineering, University of Southern California.
In their academic paper they considered the courier delivery problem, a variant of the vehicle routing problem with time windows in which customers appear probabilistically and their service times are uncertain. They used scenario-based stochastic programming, with recourse to model the uncertainty in customers and robust optimization for the uncertainty in service times. The proposed model generates a master plan and daily schedules by maximizing the coverage of customers and the similarity of routes in each scenario while minimizing the total time spent by the couriers and the total earliness and lateness penalty.
The computational results show that their heuristic improves the similarity of routes and the lateness penalty at the expense of increased total time spent when compared to a solution by independently scheduling each day. Experimental results also show improvements over current industry practice on two real world data sets. While interesting, the operational pragmatism of ergonomic factor, route delivery safety, and other considerations were not examined.
