Prof. Perakis' Energy Related Research and Teaching

 

My involvement with the Energy field started in earnest as early as 1982, when I was doing a 2-year MBA at the Sloan School, MIT in parallel with my Engineering PhD studies, and chose to do my thesis at Sloan on the evolution and the prospects of the tanker shipping industry (crude oil, products, LNG/LPG, chemical tankers, plus pipelines, form the vast majority of the oil (the biggest of fossil and non-fossil fuels, about 40% of world energy consumption). Since then, and for more than 25 years, I have been following many aspects of the oil and energy industry in general, and since the Internet came of age, I do so on a daily basis.

 

After I joined the UM in 1982, I conducted several sponsored research projects funded by the US Maritime Administration, the National and Michigan Sea Grant Programs, and UM Funding (two Rackham grants) to optimize (ie minimize the cost) of routing and scheduling fleets of ships (both strategic and operational, including ship weather routing), and specifically did more than two decades of work on "Fleet Deployment", the minimum-cost operation and scheduling of a fleet of ships (different research for each different ship category, such as Dry and Liquid Bulk ships, and Liner Ships (containerships). In the case of the dry bulk fleets, we minimized cost by optimally selecting the speed of each vessel, so that the total operating cost is minimized. Of course, for most cargo ships, fuel cost is the largest operating cost category, so by minimizing total costs, we usually also minimize fuel cost, fuel amounts, and also emissions, per ton-mile of cargo carried.

 

My work on optimal energy utilization in marine transportation produced at least two (and a third by this June 30) PhD theses:

 

Nikiforos Andrew Papadakis, On the Optimal Ship Weather Routing Problem, December 1987,

 

Zhiyong Yang, Predictions of Modal Shifts in Export Shipments from the Great Lakes due to Mandatory Ballast Water Treatment Using Game Theory, May 2003.

 

(Working with funding from a multi-year Sea Grant project, developed novel game theoretic models and solutions to determine modal shifts, with significant implication in terms of higher fuel consumption and environmental air and noise pollution, highway fatalities and injuries etc, due to proposed measures to limit the introduction of non-indigenous species in the Great Lakes and the Seaway), and several Master's Theses:

* William Mark Bremer, A Scheduling Optimization System for Tanker Shipping, April 1991.

* David Nels Amble, Inland Waterway Industry Study: Technical and Management Improvements, June 1993.

* Jun Li, Models and Statistical Analysis of Deep Draft Ship Data for U.S. Corps of Engineers Port Planning, June 1995

Here is a list of relevant publications (starting with the most recent)

 

1.1        S-C. Cho and A.N. Perakis, "An Improved Formulation for Bulk Cargo Ship Scheduling with a Single Loading Port," Maritime Policy and Management, Vol. 28, No. 4, pp. 339-345, 2001

 

(Developed an improved, much more efficient formulation for a bulk ship scheduling problem (first modeled by Ronen 1986), eliminating nonlinearities and numerous unnecessary integer variables, making the solution possible by just using available integer programming software for personal computers. Our approach also provides a natural decomposition structure that can be exploited to develop new heuristics to solve larger, more complex problems.)

 

1.2        Rosello, B.J. and A.N. Perakis, "An Efficient Single-Screw-11,000 TEU Containership: The 'Suez Max SS,' Marine Technology, Vol. 38, No. 4, October 2001. (we obtained 15% lower cost than the next best design (by a Dutch professor) by being able to use the largest possible Diesel engine and a single propeller, instead of two, largely due to the much lower fuel consumption for the same speed)

 

1.3        N.A. Moore and A.N. Perakis, "Development of a Diesel Engine Reliability Database for the U.S. Coast Guard," Marine Technology, Vol. 36, No. 3, pp. 127-142, July 1999. (lowering fuel consumption and overall costs by optimal maintenance for minimal failures)

 

1.4        A.N. Perakis and J. Li, "Recent Technical and Management Improvements in U.S. Inland Waterway Transportation," Maritime Policy and Management, Vol. 26, No. 3, pp. 265-278, 1999. ( We solved an important question of the US Corps of Engineers, i.e.; whether their observed decrease in fuel tax revenue, despite the larger amounts of cargo carried and higher fuel tax per gallon, was due to technical or management improvements; it was clearly due to different transport patterns, a significant reduction in empty return trips, and other market changes)

 

The following significant publications have been summarized in the following book chapter:

 

A.N. Perakis, "Fleet Operations Optimization and Fleet Deployment," chapter 26 in Handbook of Maritime Economics and Business, invited and refereed chapter, C. Th. Grammenos, Editor, Lloyd's of London, pp. 580-597. Book commemorated the 10th Anniversary of the founding of IAME, the International Association of Maritime Economists.

 

The main type of problems I solved here were the optimal determination of individual speeds of fleets of generally different ships in order to reduce fuel consumption significantly and overall operating (variable) costs: The optimal such speed for one individual ship, is generally quite different than the optimal speed when that ship is part of the fleet, a far more difficult problem to solve optimally. This research started in Fall 1982, when I discovered and corrected an error (imposition of an artificial constraint producing suboptimal results) in a 1981 approach to bulk shipping fleet deployment, obtaining at least 15% lower total annual operating costs. Subsequently performed extensive research on more complex and realistic fleet deployment models (1983-87). I then formulated and implemented linear/integer programming models for liner shipping fleet deployment, and for operational tanker scheduling (1989-91). Details can be found in the publications below:

 

We also provided elegant analytical solutions and elliptical bounds for the optimal state evolution for several versions of the deterministic, time-dependent and stochastic ship weather routing problems (1986-89). Portions of that work were published in "flagship" journals of the operations research community. (1.11, 1.12, 1.13 and 1.14 below) The general models developed apply not only to ship routing problems, but to any autonomous robot moving over a non-uniform 2-D (extensible to 3-D) terrain.

In May 1989, I was the first in a series of invited academics, to offer a four-hour seminar on Probabilistic Modeling and Optimization in Marine Transportation (heavily based on my own research) at Chevron Shipping Co, San Francisco, CA, and ensuing half-day workshop, interacting with employees at various Chevron Shipping Departments.


More recently, I and a PhD student work on Short Sea Shipping alternatives to Highway Truck (and Train) Transportation, with obvious benefits not only in reduced energy consumption, but also additional savings from the resulting alleviation of highway congestion, including environmental pollution, accidents, fatalities and injuries, and noise pollution. Short Sea Shipping also includes inland waterways, which are already and for a long time, a significant and very efficient component of US marine Transportation. The recently passed Energy Legislation in the USA has a section promoting Short Sea Shipping as a way to achieve the above goals.

I include a large share of my above research in my undergraduate and graduate teaching. In undergrad courses, I include energy-intensive examples in my NA387 Probability and Statistics course, and in grad courses I devote an entire, very popular course (NA582(3)) to study Reliability and Safety Analysis of Systems (Cross-listed as MFG 579), and a large portion of my other graduate course NA580(4), also cross-listed with the Program in Manufacturing, is devoted to teaching state-of-the-art in Fleet Deployment and Ship Routing, as well as the economics of International Trade, with case studies for several different oceangoing cargo ships. We also devote several lectures on Cartels and Cartel Economics, with OPEC used as a case study, and its impact on Tanker shipping."
