I began writing this letter on a boat in Halong Bay, Vietnam, traveling on International Plant Trek with 41 of the LGO '16s, with our vessel proudly flying the MIT flag. Now that we're back on campus, I'm amazed at everything we saw and did during five intense days in Shanghai and Hanoi: visits to Caterpillar, WNC (a Verizon supplier), SanDisk, the Port of Shanghai, Piaggio and Converse; a keynote address by Honeywell China CEO Stephen Shang; gracious receptions by our CLGO friends from the Shanghai Jiao Tong University (SJTU); and a memorable karaoke night (apparently there is a saying in China that what happens in a karaoke bar in Shanghai stays there).
Together with Academic and Student Affairs Coordinator Patty Eames, our students once again did a fantastic job in planning and executing a plant trek. The CLGO students went out of their way to make us feel welcome and experience the essence of Chinese culture and Shanghai life. It was particularly rewarding to see how well the two groups interacted and the bonds of friendship that began to form across continents and cultures.
The visit was a powerful reminder of the opportunities offered by our ties with CLGO. With only two Lion Team projects at Apple and Verizon this year, we are not fully taking advantage of this partnership, and I hope that more Lion Teams will form in the future. Both partner companies and students in the two programs would benefit greatly.
The LGO staff is finally complete again after Ekaterina Trizlova joined us as our new Senior Financial Administrator. Katja brings a lot of experience from Tufts University and I'm excited to working with a complete staff for the first time since joining LGO last summer.
Finally, I would like to thank Jane Deutsch, who retired in early March after many years as LGO’s admissions director. We are grateful for her many contributions to the program and for the excellent cohorts of students recruited by her. Enjoy your retirement, Jane!

The Alumni Newsletter includes periodic first-person accounts by students who have benefited from an LGO Alumni Scholarship.
When I first encountered the Leaders for Global Operations program, it was still called Leaders for Manufacturing. I was an undergraduate at MIT at the time and started to hear about the program—a professor first mentioned LGO during one of my classes and then I noticed an LGO student in another class (later, as an LGO myself, I would run into her during alumni events).
Years later, when I began to look at graduate programs, I immediately realized that LGO was a great fit for what I was interested in. I had been exposed to operations during my time as an undergrad and wanted to learn more about the field—in particular, I wanted to focus on transportation, logistics and supply chain. As someone who was unsure about business school or pursuing a master’s in engineering (I ended up applying to both), the dual-degree program was very attractive to me. LGO ended up being the perfect mix of coursework, exposure to operations and research that I was seeking.
The size of the LGO program (approximately 50 per year) also was an attractive factor. Having had a fairly “mainstream” undergraduate experience, I knew that it would be invaluable to have such a close-knit community. What I didn’t consider at the time, however, was that a small class size also meant a tight alumni base.
Over the course of the program, I’ve been continuously surprised by the support of the alumni community—from the sponsorship/support of alums during plant trek, to the WLGO webinars, to the whitewater rafting trip I went on arranged by an LGO alum, to the LGO reunion BBQ hosted by an alum at her house during my internship, to the LGO alums who eagerly introduced themselves to me during my full-time recruiting process, to the LGO alum who will be the skipper for our BVI boat, etc. The alumni truly help make this program not only possible, but also an amazing experience.
I am truly grateful to be a recipient of an Alumni Scholarship.

This month will feature two projects involving predictive modeling to assist in the planning for preventative maintain and risk mitigation. Rick Mullen worked on corrosion modeling for Pacific Gas and Electric to avoid leaks or other more catastrophic failures. Daniel Roberson worked on engine interval prediction at Pratt and Whitney, a UTC company, one of the findings from his work was that engine life can be tied to route patterns used by the airlines.
If you have companies or areas of research you are interested in having highlighted in the monthly news, please contact Ted Equi (firstname.lastname@example.org).
Metallic corrosion is the third-largest cost to the U.S. economy after healthcare and real estate. A National Association of Corrosion Engineers study estimates the direct and indirect costs of corrosion within the U.S. at 6.2 percent of GDP. The study concluded that the use of optimal corrosion prevention and control methods would increase public safety, prevent damage to property and the environment, and save billions of dollars. PG&E is dedicated to discovering those optimal processes that will help them become the safest, most reliable gas company in the U.S.
Currently, federal regulation requires that all utility gas assets be inspected every 36 months for atmospheric corrosion (AC). While this timeframe is conservative in many cases, it is not optimal and treats all of PG&E’s gas assets the same. California has a very wide range of corrosive atmospheres; by treating all assets the same, waste is created in some areas and system safety is decreased in others. The ability to predict where corrosion will cause system failures (leaks) and optimize the results will allow for better allocation of limited resources to minimize system risk.
The project focused on developing a model to predict where failures caused by atmospheric corrosion occur on customer meter assets. We used past meteorological data (relative humidity and temperature), past pollution data (chlorides and sulfur dioxide), 2014 AC inspections on 2.27 million meters, leak data, and gas system asset information (meter age, type, etc.). Since corrosion physics is understood, we are utilizing the existing International Organization for Standardization (ISO) corrosion model to define how corrosion progresses over time. Through data and statistical analysis, we developed a model to estimate when the corrosion-inhibiting coating on meter assets fails (thus starting corrosion) and applied a localized corrosion factor for accelerated corrosion in order to predict the number of failures in a defined geographic area.
Using this model, PG&E can determine the optimal meter asset corrosion inspection frequency, thus improving system safety. From the analysis, we also identified several opportunities for PG&E to improve the AC inspection process. By collecting targeted data on localized corrosion and atmospheric corrosion rates, the model can be improved to provide more accurate results in determining optimal inspection intervals.

Airplane engine maintenance contracts represent a significant portion of overall customer value to airline operators. Maintenance contracts are awarded competitively by the operator to one of three options: independent maintenance repair and overhaul (MRO) companies, airline-operated MROs, and the engine’s primary original equipment manufacturer (OEM).
The pricing of these contracts is developed carefully by the OEM based on predicted time on wing (interval) and maintenance costs. While historical methods have provided accurate assessments of typical costs, the potential exists for improved use of available data in forecast engine lifetime and maintenance costs. An algorithm will be developed having the capability to predictively model engine lifetime and damage based upon currently available engine lifecycle information. A final product will be delivered to Pratt & Whitney containing a heuristic for deriving this algorithm using engineering provided relationships for any specific engine design. A method will be documented by which this system can be implemented to the existing simulation software used by Pratt & Whitney for cost estimating.
The project also involves developing data acquisition and storage methods within the company that considers the impacts of the current organizational structure and incentives for data maintenance. The implications upon the data usability and recommendations for data architecture will be provided.
A system dynamics model was created through interviews within the engine services and life prediction groups to identify the primary drivers of engine damage. These damage sources were mapped to available data, and relationships were analyzed to inform screening methods. Engine lifetime and damage accrual varies by section, and failure modes unique to sections were identified.
Data covering engine performance, maintenance, operations, and worldwide weather data was collected. All data was gathered into a Teradata database and rationalized by flight, while maintenance records are tabulated by section. The targeted response for the section will be the probability distribution for failure of each module as a function of measurable parameters. Existing engineering models for predicted engine life are used to form the basis of the regression model. The physics-based model to compute a residual life factor representing the deviation between each maintenance interval and the expected life. The data is transformed by Kaplan Meier method to enable parametric survival analysis.
The work has identified significant primary and cross-terms as damage drivers that directionally agree with physical interpretations. De-correlation of regional effects is made possible by mapping of cause and effect through physics-based models. The present value of ongoing maintenance can be established for certain maintenance procedures. Strong predictive power is achieved for new fleets prior to first engine failure provided that cities in the fleet flight network are consistent cities used in the model development. Implementation of the models to future engines will be possible by careful factor consideration by engineering teams.
