Agent-Based Modeling of an Optimal Maintenance Program for Green Stormwater Infrastructure Assets under The Clean Water Partnership in Prince George’s County, MD
Interim Chair and Associate Professor Morgan State University, Maryland, United States
Abstract Submission: The Clean Water Partnership which spans across multiple implementation phases has been instrumental in addressing environmental challenges in Prince George’s County, MD, while concurrently fostering sustainable workforce development efforts for green stormwater infrastructure (GSI) implementation. Over the 10 years of its establishment, a total of 354 GSI assets have been successfully installed under the CWP. However, as the program progresses, it becomes increasingly crucial to explore and understand its long-term sustainability, specifically the viability of the 30 years maintenance agreement for the installed GSI assets under the CWP. Thus, this study explores the use of agent based modeling (ABM), using the software package AnyLogic as the modeling tool, to devise optimal maintenance programs for the GSI assets over a 30 year period which transitions through different states such as operation, maintenance, repair, and replacement. The network of 354 GSI assets completed through the three phases of the partnership will be modeled as static agents, whereas the variable number of service teams available that would be responsible for maintenance tasks over the 30 years period will be modeled as dynamic agents. The overarching goal of the model is to find the optimal maintenance strategy that would ensure the GSI assets continue to fulfill their stormwater management functions in the long term.
