Local Kitchens Redefines Takeout With Digital Suburban Food Halls

Congratulations to GMU SEOR B.Sc. Class of 2014 graduate, Founder & CTO of Local Kitchens, Jason Bramble. Every process is a "systems" problem, right? #localkitchens, #systemengineering, #maketheworldabetterplace

Local Kitchens has raised $28mm to transform former restaurants into mini suburban food halls focused on the digital pickup experience featuring brands like Wise Sons, Proposition Chicken, Curry Up Now, and The Little Chihuahua.

Is this a good design?

A complex system of interacting components, designed decades ago for an environment not anticipated, is monitored and managed by unpaid, untrained, unsupervised staff, who must understand and respond to the cumulative effects of the complex interaction of independent faults. The case of the Surfside condo collapse.

Condos emerged in the 1960's as an effective way to house more people on less land, increase developer profits, and increase municipal revenues from local property taxes. It is a win-win-win.

To manage the common services (e.g. garbage collection, gardening) and infrastructure (e.g. pools, parking garages) at these buildings, Home Owner Associations (HOAs) were founded. The 350,000 HOAs in U.S. now manage a cumulative $7 billion in private properties used by 30% of U.S. population.

Anyone with experience in HOAs managing the lawn care and garbage collection knows how dysfunctional the process can be. Why should I have to pay for a common area or service I dont use? or is'nt there a cheaper way to do this? Furthermore, HOAs are designed to manage the status-quo, not an evolving climate change-driven future. No body wants to pay for roof repairs today needed for the property in the distant future.

As the infrastructure managed by the HOAs age, and the effects of unanticipated climate change affect the integrity of the properties, the HOAs must understand the impact of an accumulation of small, independent faults whose complex interactions threaten the overall integrity of the property. By the way, the HOAs are staffed by unpaid, untrained, and unsupervised volunteers,

How can a system be implemented to provide HOAs the technical knowledge to monitor, understand, and address the complex issues as infrastructure ages in an environment that was not anticipated by the designers 60 years ago? How should the laws under which HOAs operate be adjusted to address this issue?

This is a System Engineering problem!

A paper co-authored by esteemed colleague Dr. Chung-Hun Chen was featured in the IISE Magazine this month.

The paper discusses a decision problem involving running a simulation.

Due to the practical need to make decisions quickly, simulations may not be run in a long stretch of time to guarantee the reach of its steady state.

To safeguard the quality of decisions, the authors devised a sequential sampling strategy for running the simulation, conducting ranking and selection accordingly, and deciding when the decision is credible enough so that one can stop the simulation.

This article will appear in the July 2021 issue of IISE Transactions (Volume 53, No. 7).

Recommended reading: New book by System Engineering Professor Larrie Ferreiro. - Bridging the Seas: The Rise of Naval Architecture in the Industrial Age, 1800–2000

In the 1800s, shipbuilding moved from sail and wood to steam, iron, and steel.

The competitive pressure to achieve more predictable ocean transportation drove the industrialization of shipbuilding.

In Bridging the Seas, System Engineering historian Larrie Ferreiro describes this transformation of shipbuilding, portraying the rise of a professionalized naval architecture as an integral part of the Industrial Age, and as a forerunner to modern System Engineering.

Congratulations to Dr. Roman Polyak, mathematician extraordinaire, on new book: "Introduction to Continuous Optimization"

Roman developed the Nonlinear Rescaling (NR) theory and methods for constrained optimization. The NR theory overcomes the limitations of classical barrier and distance functions for Nonlinear Programming (NLP).

These methods, in particular, the Modified Barrier Functions method, has been used with great success for solving large scale real life NLP problems including planning radiation therapy ,truss topology design, optimal power flow, and antenna design.

INCOSE - Johns Hopkins University / APL Award

Systems Engineering Graduate Scholarship Opportunity

The INCOSE Foundation, a charitable organization formed by the International Council on Systems Engineering (INCOSE), is seeking nominations for the Johns Hopkins University/ Applied Physics Laboratory Alexander Kossiakoff Scholarship.

The Scholarship recognizes and encourages promising applied systems engineering research by students in a masters or doctoral program. Awardees must be U.S. citizens who show rigor and creativity in their proposed applied research and have strong academic recommendations, among other criteria. The student will receive a $5,000 grant along with an optional paid internship at JHU/APL to work on relevant systems engineering problems. The student will also be provided with a plaque and recognition at the annual winter INCOSE International Workshop. Previous recipients have come from prestigious colleges, such as the University of Southern California, George Mason University and Johns Hopkins University. The deadline for applications is Nov. 30.

New Undergraduate Specialization in Data Analytics

We are pleased to announce a new specialization in Data Analytics for the BS/SE program beginning Fall 2013. Data Analytics is the process of acquiring, extracting, integrating, transforming, and modeling data with the goal of deriving useful information. It is becoming an important (and hot) quantitative methodology in a wide variety of applications. The need for data analytics is due to the massive accumulation of “Big Data” in all industries to include but not limited to healthcare, finance, government (federal, state, and local), and cyber defense.

The specialization consists of 3 courses (9 credits):

**CS 310 Data Structures. Prerequisite(s): Grade of C or better in CS 211 and MATH 113. Offered Fall and Spring

** CS 484 Data Mining. Prerequisite(s): Grade of C or better in CS 310 and STAT 344. Offered Spring.

** STAT 463 Intro to Exploratory Data Analysis. Prerequisite(s): STAT 350 or 354, or equivalent. Offered: Alternate Springs. Will be offered Spring 2014.

Students who wishes to take this specialization MUST obtain signed approval from their advisor on their plan of study.

Because the specialization is till under development, and because STAT 463 is currently only offered every other year, some requirements may change over time. This makes it even more important that students obtain their advisor's approval before deciding on this specialization.

New Programs in Data Analytics.

The Volgenau School of Engineering will be offering a new Graduate Certificate in Data Analytics starting Fall 2013. The School has also submitted for a proposal for a Masters program in Data Analytics Engineering for approval by the State Council of Higher Education of Virginia, with a target of launching the program in Fall 2014

Data analytics (i.e., the process of acquiring, extracting, integrating, transforming, and modeling data with the goal of deriving useful information) is becoming an important quantitative methodology in a wide variety of applications. The need for data analytics is due to the massive accumulation of “Big Data” in all industries to include but not limited to healthcare, finance, government (federal, state, and local), and cyber defense.

The certificate program in Data Analytics provides a broad overview of the end-to-end value chain for Big Data Analytics, from the capture and management of the data, through the analytics that harness the data to create value. The program is designed to provide a framework for the methodologies for organizing and integrating disparate data, analyzing and visualizing the integrated data, and determining what decisions or actions should be taken to generate value from the data. The program is comprised of four courses: AIT 580 Analytics: Big Data to Information, STAT 515 Applied Statistics & Visualization for Analytics, CS 504 Principles of Data Management and Mining, and OR 531 Analytics & Decision Analysis.
