PSS-based Maintenance Simulation Modeling

Job ID: 39635683

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)
