The Value of Inaccurate Advance Time Window Information in a Pick-Up and Delivery Problem

The Bi-Objective Location-Routing Problem based on Simultaneous Pickup and Delivery with Soft Time Window

The location-routing problem is the most significant and yet new research field in location problems that considers simultaneously vehicle routing problem features with original one for achieving high-quality integrated distribution systems in beside of the global optimum. Simultaneous pickup and delivery based on time windows are the two main characteristics of logistic management that have be...

Generating Feasible Schedules for a Pick-Up and Delivery Problem

The supply-chain pick-up and delivery problem with transshipments

Abstract In this work, a strict MILP formulation for the supply-chain pick-up and delivery problem with transshipments is presented (SC-PDP-T). This problem adds the option for transferring goods from one vehicle to another. This additional flexibility is very attractive for the optimal management of supply chains. Based on the novel features of the SC-PDP-T, this work addresses the major model...

Vehicle Routing Problem with Time Windows and Simultaneous Delivery and Pick-Up Service Based on MCPSO

This paper considers two additional factors of the widely researched vehicle routing problem with time windows VRPTW . The two factors, which are very common characteristics in realworld, are uncertain number of vehicles and simultaneous delivery and pick-up service. Using minimization of the total transport costs as the objective of the extension VRPTW, a mathematic model is constructed. To so...

Real Time Vehicle Routing Problem with Time Window Simultaneously Delivery Products and Pick up Wastage Materials with Proposed Master-Slave Genetic Algorithm

The real-time vehicle routing problem with time windows and simultaneous delivery products and pickup wastage materials (RT-VRPTWDPPWM) is formulated as extension of VRP. The real-time delivery/pickup demands are served by capacitated vehicles with limited initial loads. Moreover, pickup services aren’t necessarily done after delivery services in each route. A improved genetic algorithm ( maste...
