This book describes how to plan and design efficient logistics systems considering simultaneously all integral aspects of their operation, and how to evaluate economically existing or proposed systems. The approach, more physical than mathematical, requires little data. Building on an...

We study a vehicle routing problem with soft time windows and stochastic travel times. In this problem, we consider stochastic travel times to obtain routes which are both efficient and reliable. In our problem setting, soft time windows allow early and late servicing at customers by incurring...
