New Paper in American Journal of Transportation and Logistics

My colleague and I and a student recently published a new paper in the American Journal of Transportation and Logistics.  You can see it below.  The paper is based on a presentation made at the International Association of Maritime Economists’ 2017 annual meeting in Japan.

The paper is about Ocean Trading Intermediaries (OTI’s) and their distribution across the US. The data came from the Federal Maritime Commission’s lists of registered US and foreign OTIs, which includes Ocean Freight Forwarders and Non Vessel Owning Ocean Carriers.  WE discuss the history, legal framework, and current conditions facing OTIs and make special reference to the Chicago area, in which a cluster of these businesses has arisen.

We used statistical cluster analysis to show that despite the belief that ocean freight forwarding is becoming more technology driven and thus able to locate anywhere, the businesses still choose to form clusters in major ports.

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.

Gartner Survey Reveals Scarcity of Current Blockchain Deployments

​Naturally CIOs are an entrenched bunch.  But the lack of use cases that actually work is definitely a barrier to experimentation, along with the inflated cost and risk of finding software engineers with the expertise.​
