This article explains how turning everyday tasks into structured checklists serves as an accessible entry point to modeling, illustrating the process with travel packing, year‑end reviews, and house‑buying decisions, and outlining a three‑step thinking method to boost logical and quantitative problem‑solving.
This essay explains that every modeling choice rests on hidden assumptions that encode the modeler's values, showing how different assumptions lead to different perspectives, ethical trade‑offs, and ultimately influence real‑world decisions across domains such as education, insurance, and public policy.
Discover a practical five‑step framework for turning everyday observations into clear, testable models, learn how to quantify phenomena, map variable relationships, build input‑process‑output structures, match them to known patterns, and validate their predictive power for smarter decision‑making.
The article explores how people manipulate evaluation systems by redefining variables, adjusting weights, and shifting perspectives, turning losses into perceived wins, and reveals the psychological and statistical biases that create this illusion, urging more honest, multi‑dimensional, transparent modeling for genuine assessment.
This article explains how adopting a modeling mindset—structuring real‑world problems, quantifying variables, and applying simple optimization and scheduling techniques—can bring order to everyday tasks such as time management, consumer choices, interpersonal communication, health habits, and life planning.
This article explains the core concepts and methods of sensitivity analysis, distinguishes local and global approaches, outlines the simple variation method, and demonstrates how to construct and interpret a tornado chart—complete with a real‑world example of market factors affecting sales—providing clear guidance for robust model evaluation.
The article reflects on the true nature of technology, describing it as a dynamic, recursive creative system that evolves through combinatorial innovation, recursion, and the capture of natural phenomena, and illustrates these mechanisms with examples from mathematics modeling and historical technological breakthroughs.
The article argues that modeling is a process of understanding and exploration rather than mere problem‑solving, introduces a “27‑Method” framework spanning time, space, and analogy, advocates progressive, elegant models, emphasizes the equal partnership of data and models, and links modeling to philosophical principles.
This article explains how adopting a global perspective—coordinating system structure, multiscale analysis, and visualization—helps modelers avoid local optima, understand complex dynamics, and build comprehensive models that reveal core drivers and long‑term insights.
The 2024 HiMCM competition releases two modeling challenges—Problem A asks teams to develop a quantitative model for selecting Olympic sports for the 2032 Brisbane Games based on IOC criteria, while Problem B requires assessing the environmental impact of high‑performance computing and proposing sustainable solutions.
The article argues that effective mathematical modeling relies on uncovering a problem's essence with minimal assumptions, emphasizing simplicity, careful validation, and a three‑step process—understanding key variables, building a compact model, and rigorous testing—to deliver robust, practical solutions.
The article explains the main UML architecture diagram types—class, sequence, component, deployment, use‑case, state, and activity—outlines how to choose the appropriate diagram, and details when each should be applied during requirement analysis, high‑level design, and detailed design phases of software development.
This article explains why software engineers should perform design and modeling—such as business modeling, process analysis, and system modeling—before writing code, highlighting how these practices align development with business goals, improve collaboration, and reduce costly rework caused by changing requirements.
Before writing code, developers should perform systematic design and modeling—including business modeling, process analysis, and system modeling—followed by class analysis and state‑machine design, to align software with business goals, reduce changing requirements, improve quality, and keep teams motivated.
This article explains Domain-Driven Design (DDD), its key concepts such as bounded contexts, ubiquitous language, domain models and layered architecture, traces its evolution, highlights recent trends like Event Storming and CQRS, and draws parallels to technical team management practices for handling complexity, communication, iteration, and strategic focus.
Cellular automata, a discrete mathematical modeling tool built from simple cells, grids, states, neighborhoods, and rules, can simulate complex phenomena such as traffic flow, forest fires, and urban development, demonstrating how local interactions generate emergent patterns and offering insights for scientific research and practical applications.
Domain‑Driven Design aligns software architecture with business needs by establishing a shared language, clear bounded contexts, and strategic‑tactical patterns—entities, value objects, aggregates, services, and events—while using techniques such as Event Storming and Four‑Color Modeling to visualize domains, guide micro‑service boundaries, and produce maintainable, adaptable systems.
This article explores Robin Dunbar’s social‑brain hypothesis, explains the layered structure of human relationships, proposes a vector‑based social model, and shows how similarity and difference metrics can inform personal and organizational network analysis.
This guide explains the seven core UML diagrams—class, sequence, component, deployment, use‑case, state, and activity—detailing when and how to use each across requirement analysis, architecture design, and detailed design to produce clear, actionable software design documentation.
This article compiles a categorized list of recent model papers, covering change models and various prediction models—including time series, machine learning, gray prediction, and deep learning—providing direct references for students and researchers interested in AI and data‑driven modeling.
