New Paper in Games

I recently published a new paper in the journal Games.  You can see it below.

It deals with a very important logistics problem. In a cold chain, different parcels require different conditions of temperature. A multiple compartment vehicle can be sued to consolidate loads with different temperature characteristics in one vehicle.   But loading the vehicle at a low cost is a hard problem, requiring heuristics to solve.  And even then, how do we divide the cost of loading among the different package owners in a fair way?  ‘Fair’ here means that no group of owners will choose to leave the consolidation, because they cannot do better on their own than the cost they are charged.

The paper uses an inductive algorithm on top of a common heuristic to give a method for solution. There is a small example in the paper that shows how to apply the algorithm.

DCLI acquires TRAC domestic chassis fleet

The chassis story never ceases to amaze. TRAC was positioning itself to be a big player only a couple of years ago. Now what? Is it unprofitable?  We are still wrestling with who will pay for chassis, and how to share the cost.

2015 Ocean Cargo Crisis Calls for Collaboration

A reasonable assessment of the outlook for ocean shippers. It’s all about supply chains and how you fit into them.

Ports, terminals, and ocean carriers currently comprise a family in severe dysfunction and denial, but can the intervention of shippers restore some badly needed order?

With that in mind, how can shippers better work with their carriers?

Carlton: They can help at the margins by establishing and maintaining solid long-term relationships with quality carriers. That’s a good solution for both, but it’s not enough to overcome the carriers’ own downward pressure on rates and returns from continued overcapacity.

How important are non-vessel operators (NVOs) in today’s marketplace? Will we see more reliance on these middlemen or less?

Damas: NVOs are increasingly important in an ocean market characterized by ocean carriers generally offering only a basic commoditized service. On some routes, NVOs are incredibly powerful. For small shippers who don’t have in-house freight procurement experts, this is especially true. NVOs are the natural one-stop-shop for a range of services, including consolidation and personalized customer service. For larger shippers, NVOs often serve as forwarders or 3PLs. In my view, the roles of intermediaries will increase – and ocean carriers cannot replace them.
