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

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!
Rochelle Jones, Associate Professor - Systems Engineering and Operations Research Dept. is privileged to serve on a STEMNoire panel on "Building a Competitive and Transferrable STEM Career Skillset".
The panel is part of a 3-day event aimed to dramatically increase the presence of Black women in STEM. In 2017, only 2.48% of Black women in the United States were employed in science and engineering occupations.

Mason placed No. 41 out of 475 universities around the world that are 50 years old or younger.
Dr. Chen and team win Best Paper Award at the 2021 IEEE International Conference on Communications (ICC), being held this week. This is the flagship conference of the IEEE Communications Society.
The paper is titled "Multiband Spectrum Sensing with Non-exponential Channel Occupancy Times" by Hanke Chen, Brian Mark, Yariv Ephraim, and Chun-Hung Chen.
The paper received the best paper award in the Cognitive Radio & AI-Enabled Networks Symposium.
The paper uses a new OCBA scheme to improve the probability of choosing the best open channel.
It is great to see so many diverse applications of OCBA!
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.
