Supply chain planning: let AI assist and simulation prove

November 13, 2026 Alexandra Ezhova

Two colleagues at a whiteboard planning a supply chain project: one points to a printed logistics map and timeline while holding a tablet with charts.

Be honest: when your supply chain planning software hands you a plan, do you trust it, or do you quietly open Claude and ask it to validate the findings?

Many planners do some version of the second. They export the plan to a spreadsheet, ask a colleague to sanity-check it, or paste it into a chatbot. The doubt is healthy and common. In BCG's Supply Chain Planning 2026 report, more than 70% of companies had invested in advanced planning systems, but only about one in five said automation, optimization, or AI had delivered meaningful value. A plan on screen looks precise, but nobody has seen it run through a bad month.

A chatbot can help you read the plan. It cannot show you what happens when a supplier is three weeks late and demand jumps at the same time. A simulation can: you run the plan through a model of your network and watch where it bends.

In this article we investigate how simulation does that and where AI fits in the flow as an assistant.

AI IN SUPPLY CHAIN PLANNING: A HELPFUL ASSISTANT, NOT THE DECISION-MAKER

AI is useful in supply chain planning, mostly as support for the people who plan. According to BCG, it adds the most value today in four assisting roles:

  • Demand forecasting, including promotions and new products.
  • Exception management, flagging what needs a planner's attention.
  • Interpreting data from documents, emails, and sensors.
  • Automating routine planning workflows.

These tasks speed up the work around the plan. None of them decides whether the plan is viable. Vendors promise more: Gartner predicts half of supply chain management solutions will include AI agents by 2030, with these agents making and executing decisions on their own. But an AI feature in the supply chain planning software is not evidence that a plan will hold.

But every AI model learns from the past. That creates three blind spots in supply chain planning.

Three blind spots of AI in supply chain planning compared with simulation

AI learns from the past. Simulation tests the plan against events your history has never seen, shows how it behaves day by day, and keeps every run traceable

  1. Events with no history. A new tariff regime, a closed port, or a supplier bankruptcy may never appear in your data.
  2. Behavior over time. A forecast tells you how much demand to expect, not how queues, lead times, and inventory policies will interact week by week.
  3. Explainability. When a plan fails in month seven, leadership asks why. A model that cannot show its reasoning is hard to defend.

This is why BCG concludes that fully autonomous planning is still aspirational. Only 7% of the leaders it surveyed report value from agentic or GenAI applications so far.

The same gap shows up for AI itself. In PwC's 2025 Digital Trends in Operations Survey, 59% of 610 operations and supply chain leaders already use AI. Yet 92% say their tech investments have not fully delivered, most often because of integration complexity and data issues.

STRESS-TESTING SUPPLY CHAIN PLANNING WITH SIMULATION

A stress test asks a simple question: what happens to this plan when the world does not follow the forecast? In anyLogistix, you answer it by defining the disruptions yourself. Six event types cover the most common shocks.

Six disruption event types in anyLogistix supply chain simulation

Each disruption is an event in the anyLogistix model. Set its probability and timing, chain it to other events, then compare results across replicated runs

Each event gets its own likelihood and time window, and one event can trigger another, so a port closure can cascade into a DC shutdown.

Supply chain simulation answers it. It builds a working model of your network, with sites, lanes, lead times, capacities, and inventory rules, and runs the plan through time with realistic variability. Replicated runs then turn one result into a range. Instead of one number, you get a range of outcomes and the exact points where the network strains.

SUPPLY CHAIN PLANNING RESULTS FROM REAL STRESS TESTS

How does stress-testing pay off? These anyLogistix projects combined supply chain optimization to find the best design with simulation to check that the design holds.

In each case, the team did not accept the first good-looking plan. They compared alternatives under pressure and chose the one that held.

ANYLOGISTIX: SUPPLY CHAIN PLANNING SOFTWARE FOR REAL DECISIONS

anyLogistix brings the main supply chain planning methods together in one model of your network. You can design the network, optimize it, run it through time, and check its risks without moving data between tools:

  • Network design: greenfield analysis finds the best number and locations of distribution centers.
  • Optimization: the CPLEX optimizer solves network design and sourcing questions, cost-to-serve analysis breaks down costs at every link, and last-mile optimization builds delivery routes.
  • Simulation: the engine runs the network over time with real lead times, queues, and inventory policies.
  • Inventory and risk: safety stock estimation and risk analysis show how much buffer you need and where the network is exposed.
  • Ten experiment types that work on the same network data: the results are on the map and in dashboards that any colleague can review and reproduce.

For teams, anyLogistix Professional Server turns the model into a shared workspace. It runs on your own server, so your supply chain data stays in-house, and planners open projects in a web browser on any device, including tablets. Colleagues can share projects with each other, while an administrator manages users and licenses. Professional Server also includes the anyLogistix API for Java and Python, so you can connect the model to your own systems and scripts.

To see anyLogistix Professional Server in action, check out the demo video with the anyLogistix Support Team Lead.

Whether it's a colleague, a script, or an AI tool interacting with the model, the model remains the single source of truth. That is why AI follows the same rule here as in the rest of this article: it assists. anyLogistix is exploring AI to streamline workflows around the model, such as turning spreadsheets into a valid scenario and summarizing what changed in a run. The solver and the simulation engine stay deterministic, so every number points back to a run you can reproduce.

A 5-STEP PLAYBOOK TO STRESS-TEST YOUR SUPPLY CHAIN PLANNING

You can add stress tests to your current supply chain planning process without replacing your systems. Start small, with one decision that matters.

Five steps to stress-test supply chain planning from plan to go-live

From plan to go-live in five steps

  1. Pick a decision with real money at stake. A new DC, a second supplier, a change in safety stock. Skip cheap, reversible decisions you can test for real.
  2. Build a baseline model of the network. Load sites, lanes, products, costs, and capacities from Excel files or a database, for example, ERP exports. Supply chain planning software with built-in templates speeds this up.
  3. Define the stress scenarios. Write down three to five "what ifs": a demand spike, a closed DC or lane, a 25% tariff on one cross-border route. Include at least one event your history has never seen.
  4. Run the simulation and compare. Look at the spread of service level, costs, and inventory across runs, not only the average. Note where and when the network breaks.
  5. Feed the results back. Adjust the plan, then share the animated runs with stakeholders. Let AI assist where it helps, preparing data, forecasts, and run summaries, but validate any AI-generated plan the same way before go-live.

Maturity pays off. BCG found that the most mature planning organizations beat the least mature on forecast accuracy by more than 25 percentage points.


FAQ

What is supply chain planning?

Supply chain planning is the process of matching supply with demand across a network: what to make, buy, store, and ship, and where and when. It covers long-term network design, mid-term sales and operations planning, and short-term production and distribution plans.

What are the steps of the supply chain planning process?

A typical cycle includes demand planning, supply and capacity planning, inventory planning, and sales and operations planning (S&OP), followed by execution and review. A stress test with simulation before execution shows whether the plan will hold.

What is the difference between supply chain optimization and supply chain simulation?

Supply chain optimization finds the best plan for a given goal and set of constraints. Supply chain simulation runs that plan over time with variability and disruptions and shows the range of results you can expect.

How do I choose supply chain planning software?

Choose a tool that models your real network, combines optimization and simulation, compares scenarios on business KPIs, and imports data from your ERP. The fastest way to judge is to test it on a real decision, for example, in the free anyLogistix Sandbox.

How is AI used in supply chain planning?

Mainly as an assistant: for demand forecasting, exception alerts, data interpretation, and workflow automation. It supports planners but does not replace testing. Any plan it suggests still needs to be checked in supply chain planning software.

TEST SUPPLY CHAIN PLANNING DECISIONS BEFORE REALITY DOES

So, back to where we started. Next time you are at the supply chain planning stage, go ahead and ask Claude what it thinks. Just don't stop there. Put the plan in a model and simulate everything you could think of. Then walk into the planning meeting with proof.
