Simulation Engineering for Manufacturing & Logistics.
Validate system performance, predict bottlenecks, and secure your ROI before you cut steel.
Static CAD Cannot Predict Dynamic Failure
Don’t sign a multi-million dollar CapEx request based on a "Black Box" vendor proposal.
Static drawings rely on "average" conditions. Your facility lives in the margins, where variability destroys throughput.
DSI Simulation Engineering validates the physics of your system before you commit capital, ensuring the design survives the reality of production.
The Hidden Latency in Brownfield Sites
Static layouts show you space, not time. They cannot reveal that your upstream conveyor is 5% too fast for the new downstream packer.
We analyze the dynamic flow of your specific layout to find these invisible bottlenecks, and the lost cycle time they cause, before they become permanent concrete.
The AGV "Deadlock" Risk
An AGV fleet is only as good as its logic. Without simulation, you risk creating "traffic jams" where expensive vehicles fight for right-of-way.
We validate the routing rules first, guaranteeing that your automation flows rather than freezes.
Throughput Verification (Peak JPH)
"Average" throughput is a metric for failure. You need to know if the system survives the peak.
We stress-test your facility against its worst days, simulating specific product mix surges, starvation events, and the critical recovery time after a mechanical fault.
We replace "estimated capacity" with "proven capability," giving you the hard data required to defend your ROI to the board.
What is Simulation Engineering?
It is the transition from theoretical design to mathematical certainty.
Simulation Engineering is the creation of a functional Digital Twin, a dynamic virtual model that replicates the physics, logic, and timing of your manufacturing environment. While static layouts define where equipment goes, simulation validates how it performs. We isolate variables to predict system behavior, ensuring your facility operates as intended before the first beam is installed.
We divide this discipline into two critical vectors:
Process Simulation (The Logic of Flow)
Optimizing Throughput & System Dynamics
Utilizing industry-standard engines like AutoMod and PlantSim, we execute Discrete Event Simulation (DES) to model the flow of materials and information. We program the specific logic of your PLC interactions, conveyor speeds, and merging rules to validate system capacity.
Applications are warehouse congestion analysis, AGV fleet sizing, and bottleneck identification in mixed-model assembly lines.
Structural Analysis (The Physics of Integrity)
Validating Load Limits & Safety Factors
We employ Finite Element Analysis (FEA) to stress-test the physical components of your system. This ensures that the equipment supporting your flow can withstand the mechanical demands of peak operations without fatigue or failure.
Applications are validating overhead carrier integrity, testing racking load capacities, and analyzing fatigue points in custom tooling.
Comprehensive Simulation Services
DSI applies multiple simulation methodologies to address both system behavior and physical constraints.
Each capability is used deliberately based on the decision you need to make, the risk you need to reduce, and the performance you need to prove before implementation.
Discrete Event Simulation (DES)
Discrete Event Simulation is used to model process flow over time.
DSI simulates complex interactions between equipment, material, labor, and logic to evaluate throughput, production mix, and system responsiveness under real variability.
This enables defensible answers to critical “what if” questions before layout changes, automation investments, or capacity expansions are approved.
Finite Element Analysis (FEA)
Finite Element Analysis validates whether system components can physically withstand operational loads. DSI’s FEA consulting engineers analyze stress, deflection, and failure risk in structures such as racking, carriers, and overhead systems.
This prevents overdesign, underdesign, and catastrophic failure before fabrication or installation begins.
System Optimization
Using engineering simulation software, DSI identifies bottlenecks and constraint interactions that limit performance.
The focus is not theoretical improvement, but engineered recommendations.
These are changes to logic, layout, sequencing, or resources that measurably improve system operation and reduce operational risk.
Why North American Manufacturers Choose Design Systems, Inc.
When simulation results influence capital approval and operational risk, experience and execution matter. Design Systems, Inc. has been applying industrial engineering and simulation methodologies since 1983, long before digital manufacturing became a trend. That longevity translates into repeatable, proven decision support for complex manufacturing and logistics systems.
Four Decades of Engineering Continuity
DSI is not a startup or a software reseller. With over 40 years of continuous industrial engineering practice, DSI understands how systems behave beyond ideal assumptions across product mix changes, aging equipment, and real operational variability.
Tool-Agnostic Simulation Expertise
DSI engineers are certified and experienced in AutoMod, Plant Simulation (PlantSim), and FEA platforms, selecting the right methodology based on the problem, not the software. This ensures analysis accuracy without forcing your system to fit a predefined tool.
Local Support Across North America
With engineering teams in the United States (Detroit), Mexico (Saltillo and Querétaro), and Canada (Windsor), DSI supports simulation projects directly at your facility. This enables accurate data capture, stakeholder alignment, and rapid iteration throughout the project lifecycle.
Deliverables Built for Engineering and Finance
Every engagement produces more than insight. Clients receive a Simulation AVI file, Detailed Technical Specification, and Results Summary Report—providing traceable engineering logic for technical teams and defensible ROI justification for executive leadership.
