Tecnomatix APS Manufacturing Simulation Model

Project: Development of a Manufacturing Simulation Model Using Siemens Tecnomatix Plant Simulation

Project Overview

I am looking for an experienced Siemens Tecnomatix Plant Simulation specialist to assist with developing a realistic discrete-event manufacturing simulation model.

The objective of this project is to investigate and quantify the performance improvements that Advanced Planning and Scheduling (APS) approaches can offer compared to traditional production scheduling methods.

The research will focus primarily on production scheduling. Rather than implementing a commercial APS software package, we intend to develop and implement an APS-inspired scheduling algorithm that can be evaluated against conventional scheduling rules such as FIFO/FCFS, SPT, LPT and EDD.

Manufacturing System Development

An initial simulation model has already been developed as part of previous research. However, the existing model is relatively simplistic and does not sufficiently represent the complexity of real manufacturing environments.

We therefore want to develop a more realistic production system in Siemens Tecnomatix Plant Simulation.

The new model should incorporate manufacturing characteristics such as:

- Multiple products with different processing requirements and production routes.
- Multiple machines and shared production resources.
- Alternative processing routes where applicable.
- Production processes where components split into different paths and merge at later stages.
- Intermediate buffers with limited capacities.
- Different processing times depending on the product and operation.
- Resource constraints and realistic production bottlenecks.
- Variable processing times to represent production variability.
- Machine breakdowns and downtime where appropriate.

The objective is not necessarily to simulate a very large factory, but to create a sufficiently complex and realistic production environment in which congestion, waiting times, resource competition and bottlenecks naturally occur.

Production Scheduling Implementation

The simulation model should support the implementation and comparison of different production scheduling strategies.

These may include:

- FIFO/FCFS – First In, First Out / First Come, First Served.
- SPT – Shortest Processing Time.
- LPT – Longest Processing Time.
- EDD – Earliest Due Date.
- NEH heuristic, where applicable.
- An APS-inspired scheduling algorithm that considers multiple production factors when prioritising production orders.

The scheduling strategies should be interchangeable within the same production model, allowing performance comparisons under identical manufacturing conditions.

Performance Measurement and KPIs

The simulation should provide the ability to measure and compare relevant manufacturing performance indicators, including:

- Makespan.
- Total production throughput.
- Work-in-progress (WIP).
- Average waiting time.
- Machine utilisation.
- Machine idle time.
- Blocking and starvation.
- Buffer occupancy.
- Order tardiness and delivery performance.

The model should ideally support multiple simulation replications and different production scenarios to evaluate how scheduling strategies perform under varying operating conditions.

Expected Deliverables

- A fully functional Siemens Tecnomatix Plant Simulation model (.spp).
- A realistic manufacturing system with multiple products, machines, production routes and resource constraints.
- Implementation of interchangeable scheduling rules.
- Integration of an APS-inspired scheduling algorithm.
- Automated KPI collection and reporting.
- Ability to run different simulation scenarios and experiments.
- Documentation explaining the model architecture, simulation logic and scheduling implementation.

### 5. Required Expertise

I am looking for someone with practical experience in:

- Siemens Tecnomatix Plant Simulation.
- Discrete-event manufacturing simulation.
- Production planning and scheduling.
- SimTalk scripting.
- Scheduling heuristics and optimisation algorithms.
- Manufacturing performance measurement and bottleneck analysis.

Collaboration and Project Approach

I can provide the previous research project and its associated simulation materials as a starting reference.

The project will be developed collaboratively, beginning with the design of the manufacturing system and its production logic before progressing to implementation and testing.

The exact factory configuration, number of machines, product routes and model complexity can be discussed and refined during the initial project phase.



I am interested in working with someone who can contribute both technical implementation skills and practical manufacturing simulation knowledge.
