We address a single commodity Pickup and Delivery Vehicle Routing Problem from the literature. A network of customer nodes is given with both travel times costs. fleet vehicles limited capacity exploited to satisfy node demands, set routes must be found such that vehicle capacities are never exceeded, each route does not exceed time resource, cost minimized. The demands pickup delivery can spli...

Neighborhood search is a cornerstone of state-of-the-art traveling salesman and vehicle routing metaheuristics. Whereas neighborhood exploration procedures are well-developed for problems with individual services, their counterparts one-to-one pickup-and-delivery more scarcely studied. A direct extension classic neighborhoods often inefficient or complex because the necessity jointly considerin...

One important requirement of modern supply chain management is the frequent exchange containers via multiple cross-docks which requires spatial and time synchronisations between different types vehicle. Moreover, as collaborations in logistics several companies become popular, more flexible extended models must be solved to consider needs companies. This high importance a new concept, Physical ...

We analyze a business model for e-supermarkets to enable multi-product sourcing capacity through co-opetition (collaborative competition). The logistics aspect of our approach is to design and execute a network system where ‘‘premium’’ goods are acquired from vendors at multiple locations in the supply network and delivered to customers. Our specific goals are to: (i) investigate the role of pr...

This contribution gives an introduction to an integrated vehicle routing and resource allocation problem. We refer to it as the Swap Trailer Problem and formulate the mathematical model. After the analysis of dynamic decision problems and the development of a framework for this problem, we highlight the dynamic aspect of the problem. Two different solution strategies are supposed. Special prope...

A multiobjective-model-based predictive control approach is proposed to solve a dynamic pickup and delivery problem in the context of a potential dial-a-ride service implementation. A dynamic objective function including two relevant dimensions, user and operator costs, is considered. Because these two components typically have opposing goals, the problem is formulated and solved using multiobj...
