Optimal Design of Demand-Responsive Feeder Transit Services

Quadrifoglio, Luca (contributor) - 2009

The general public considers Fixed-Route Transit (FRT) to be inconvenientwhile Demand-Responsive Transit (DRT) provides much of the desired flexibility with adoor-to-door type of service. However, FRT is typically more cost efficient than DRT todeploy. Therefore, there is an increased interest...

A method for distribution network design and models for option-contracting strategy with buyers' learning

Lee, Jinpyo - 2008

This dissertation contains two topics in operations research. The first topic is to design a distribution network to facilitate the repeated movement of shipments from many origins to many destinations. A method is developed to estimate transportation costs as a function of the number of...

Time Slot Management in Attended Home Delivery

Fleischmann, Moritz; Agatz, Agatz, N.A.H.; Campbell, A.; … - Erasmus Research Institute of Management (ERIM), … - 2008

Many e-tailers providing attended home delivery, especially e-grocers, offer narrow delivery time slots to ensure satisfactory customer service. The choice of delivery time slots has to balance marketing and operational considerations, which results in a complex planning problem. We study the...

A vendor managed inventory model using continuous approximations for route length estimates and Markov chain modeling for cost estimates

Larsen, Christian; Turkensteen, Marcel - In: International Journal of Production Economics 157 (2014) C, pp. 120-132

We consider a vendor who supplies goods to a set of geographically dispersed retailers and can monitor and control the inventory levels at the retailers. Such an arrangement is often called vendor managed inventory (VMI). The decisions in this set-up are the inventory levels at the warehouse and...
