SysML Extension for Logistics Modeling and Analysis (SysLMA)

April 23, 2025
Author(s)
Raphael Barbau, Conrad Bock
Many engineers use analysis tools to predict behavior or find optimal values for properties of systems built to proposed designs, informing system design work by identifying cases where a design will perform incorrectly or in suboptimal ways. Design and

From Principles to Practice: Product Design Foundations for a Circular Economy

January 23, 2025
Author(s)
Buddhika Hapuwatte, Noah Last, Sami Karsli, Gaurav Aher, Katherine Morris, Vincenzo Ferrero
A circular economy moves from the current linear model of production and consumption, i.e., the take-make-use-dispose model, to one that uses resources efficiently, avoids pollution, and creates triple bottom line (i.e., economic, environmental, and social

A Systems-Based Framework for Product Circularity Assessment

January 7, 2025
Author(s)
Gisele Bortolaz Guedes, Junwon Ko, Fazleena Badurdeen, I.S. Jawahir, Katherine Morris, Vincenzo Ferrero, Ardeshir Mashhadi, Ryan Bradley
One of the key aspects of Circular Economy (CE), particularly when focusing on the product level, lies in its emphasis on designing products to facilitate the circulation of resources and maximize value throughout their entire lifecycle. To effectively

Digital Twins for Robot Systems in Manufacturing

October 26, 2024
Author(s)
Ali Malik, Guodong Shao, Jane Tarakhovsky
The surging demand for industrial automation is propelling the use of robots, with emerging trends like autonomous mobile robots and collaborative robotic arms swiftly gaining widespread popularity. Simultaneously, a growing focus is on simplifying the

Physical Component Libraries for SysPhS Modeling and Simulation in Manufacturing

October 10, 2023
Author(s)
Charles Manion, Conrad Bock, Raphael Barbau
Computer-interpretable representations of system structure and behavior are at the center of developing today's complex systems. Systems engineers create and review these representations using graphical languages and information models that capture

A Methodology for Digital Twins of Product Lifecycle Supported by Digital Thread

February 8, 2023
Author(s)
Laetitia Monnier, Guodong Shao, Sebti Foufou
The technological advancement has led to the transition of manufacturing industries to Smart Manufacturing and Industry 4.0. Promising concepts such as Digital Twin and Digital Thread could help speed up the transition. One of the benefits of using digital

Verifying Executability of SysML Behavior Models Using Alloy Analyzer

February 24, 2022
Author(s)
Jeremy Doerr, Conrad Bock, Raphael Barbau
This report presents an approach to verifying executability of system behavior models by treating them as logical constraint problems solved using Alloy Analyzer, a non-proprietary software tool supporting a textual language for logical constraints and

Refocusing the Barriers to Sustainability for Small and Medium Manufacturers

February 14, 2022
Author(s)
Xavier R. Escoto, Demsas Gebrehewot, KC Morris
Sustainable manufacturing practices are a necessary component of sustainable development. Current practices in a linear economy—produce, consume, discard—will not be sufficient to sustain humanity over the long term. At the same time manufacturing is

Model of Operational Control of Discrete Event Logistics Systems (DELS)

July 8, 2021
Author(s)
Timothy A. Sprock, Conrad Bock
Operations management systems manage flows of work, resources, and information through production and logistics systems, ensuring the correct and efficient execution of requested work. These systems can leverage recent advances in data availability
