PSS-based Maintenance Simulation Modeling
Budget: €30 – €250 EUR
Objective
Develop a simulation model to evaluate the economic and environmental sustainability of an industrial system in a Product-Service System (PSS) context using AnyLogic.
In this scenario:
The customer purchases an asset
The provider delivers condition-based maintenance services
Project Scope & Key Elements
1. Simulation Context (PSS-based Maintenance)
You must select an industrial system where:
An asset is sold to a customer
The maintenance is delivered via a condition-based approach (predictive/monitoring-driven)
Example contexts may include:
Manufacturing machinery
Energy systems (e.g., turbines, boilers)
Transport fleets
Medical equipment
(You are free to choose any real or hypothetical setting—ChatGPT or GenAI tools should not define it for you)
2. Two Main Sustainability Evaluations
Economic Sustainability
Assessed using the Total Cost of Ownership (TCO) framework
Consider costs of acquisition, operation, maintenance, and disposal over the lifecycle
Environmental Sustainability
Calculated using CO₂ emissions:
For asset usage
For delivery and execution of maintenance
Use provided conversion factors (Conversion factors.xlsx on Moodle)
3. Technical Development Requirements
A. AnyLogic Deliverables
Causal Loop Diagram (CLD)
Depict the full PSS system and lifecycle
Include as many relevant variables, feedback loops, and relationships as possible
Base loops on hypotheses and known system behaviors
Stock & Flow Model
A simplified quantitative simulation based on the CLD
Focus on a subset of key variables
Time horizon: 24 months
Model should output key metrics related to costs, maintenance events, and CO₂ impact
Report & Presentation Deliverables
B. Written Report (Mandatory)
Must include:
Description of your reasoning process
Justification for loops and relationships in the CLD
Explanation of:
Stock & Flow logic
Formulas used for simulations
Assumptions made
Interpretation of simulation results
Reflection on limitations and improvement areas
Evaluation based on:
Quality and depth of the simulation model
Clarity and logic of written report
Presentation and defense of the work
Understanding of concepts (TCO, sustainability, maintenance, PSS)
