than convincing somebody of a reality they can not see in their very own knowledge.
Information science and sustainability consultants face the identical downside: our ideas could also be too summary and theoretical, making them troublesome for decision-makers to narrate to.
I discovered this the onerous method whereas developping my startup!
Once I printed a case examine on Inexperienced Stock Administration on TDS in 2024, I assumed the logic was strong and convincing, however the influence was restricted.
The article defined the mathematical principle behind it and used an precise case examine to exhibit the sustainability advantages.
But it didn’t convert sceptics.
Buyer: “I’m positive it gained’t work with our operations!”
Why? As a result of it wasn’t related to their knowledge and constraints.
So I made a decision to vary the strategy.
I packaged the simulation software in a FastAPI microservice and gave my clients the power to check the mannequin themselves utilizing an MCP Server related to Claude Desktop.
The target was to have them ask the LLM to run their very own eventualities, regulate their parameters, and see how CO₂ emissions dropped in response to completely different stock insurance policies.
On this article, I’ll share the strategy I used for this experiment and the suggestions I acquired from a prospect, the Provide Chain Director of a retail group primarily based within the Asia Pacific area.
What’s Inexperienced Stock Administration?
On this part, I need to briefly clarify the idea of Inexperienced Stock Administration so you’ve the context to grasp the software’s added worth.
Context: Stock Administration for a Retail Firm
Allow us to put ourselves in our Provide Chain Director’s sneakers.
His groups (stock groups, warehouse and transportation operations) are answerable for replenishing shops from a central distribution centre.
Once they want particular merchandise, shops mechanically ship replenishment orders by way of their ERP to the Warehouse Administration System.
These automated orders observe guidelines carried out by the stock staff, often called the periodic assessment “Order-Up-To-Degree (R, S)” coverage.
- The ERP is reviewing shops’ stock ranges, additionally referred to as stock readily available (IOH), each R days
- The delta between the goal stock S and the stock degree is calculated: Δ = S— IOH
- A Replenishment Order is created and transmitted to the warehouse with the amount: Q = S — IOH
After transmission, the order is ready on the warehouse and delivered to your retailer inside a selected lead time (LD) in days.
To be extra concrete, I share the instance above:
- R = 25 days: we assessment the stock each 25 days as you possibly can see within the blue scatter plot
- S = 1,995 items: we ordered to achieve this degree, as proven within the newest graph.
The stock groups within the methods normally set these parameters, and the replenishment orders are mechanically triggered.
What if we optimise these parameters?
Impacts on Logistics Operations
Based mostly on my expertise, these parameters are, more often than not, not set optimally..
The issue is that they considerably influence the effectivity of your warehouse and transportation operations.
This will increase carton and plastic consumption and reduces productiveness.
Within the instance above, objects are saved in cartons containing items that may be picked individually.
If the order amount is 5, the operator will:
- Open a field of 20 items and take 5 items ;
- Take a brand new field and put these things in it ;
- Palletise the bins utilizing plastic movie ;
The opposite influence is on truck filling charge and CO2 emissions.
With a excessive supply frequency, you cut back the quantity per cargo.
This results in the usage of smaller vans that will not be full.
What can we do?
Aims of Inexperienced Stock Administration
We are able to check a number of eventualities, with completely different operational parameters, to search out the optimum setup.
For that, I’ve loaded buyer knowledge into the simulation mannequin
to check the software with actual eventualities.
Customers can regulate a few of these parameters to simulate completely different eventualities.
class LaunchParamsGrinv(BaseModel):
n_day: int = 30 # Variety of days within the simulation
n_ref: int = 20 # Variety of SKUs within the simulation
pcs_carton: int = 15 # Variety of items per full carton
cartons_pal: int = 25 # Variety of cartons per pallet
pallet_truck: int = 10 # Variety of pallets per truck
okay: float = 3 # Security issue for security inventory
CSL: float = 0.95 # Cycle service degree goal
LD: float = 1 # Lead time for supply (days)
R: float = 2 # Overview interval (days)
carton_weight: float = 0.3 # Carton materials weight (kg)
plastic_weight: float = 0.173 # Plastic movie weight per pallet (kg)These parameters embrace:
n_dayandn_ref: outline the scope of simulationpcs_carton,cartons_pal,LDandpallet_truck: parameters linked to warehousing and transportation operationscarton_weight,plastic_weight: sustainability parametersR,okayandCSL: parameters set by the stock staff
I would like our Provide Chain Director to sit down together with his groups (stock, warehouse, transportation and sustainability) to problem the established order.
If they should attain a selected goal, our director can:
- Problem his stock groups to search out higher assessment intervals (R), or cycle service degree (CSL) targets
- Ask the sustainability staff to search out lighter carton supplies
- Redesign his warehouse operations to scale back the lead time (LD)
For that, we have to present them with a software to simulate the influence of particular modifications.
That is what we’re going to do with the assist of an MCP Server related to Claude AI.
Demo of the Inexperienced Stock Administration AI Assistant
Now that we all know how this simulation software can add worth to my clients, let me present you examples of analyses they’ve carried out.
These assessments have been carried out utilizing buyer knowledge over a simulation horizon of as much as 90 days.
I’ve replicated the questions and interactions utilizing anonymised dummy knowledge to keep away from sharing confidential data right here.
Onboarding of customers
I’ve related the MCP server to the Claude setting utilized by the Provide Chain managers to have them “play with the software”.
The bulk didn’t take the time to assessment the preliminary case examine and instantly requested Claude concerning the software.
Hopefully, I’ve documented the MCP instruments to supply context to the agent, like within the toot launch_greeninv shared under.

def launch_greeninv(params: LaunchParamsGrinv):

🌱 WHAT THIS TOOL DOES
-------------------------------------------------------------------------
It runs the total simulation described within the "Inexperienced Stock Administration"
case examine, reproducing the conduct of an actual retail replenishment system
utilizing a (R, S) Periodic Overview Coverage.
The simulation estimates:
- Replenishment portions and order frequency
- Inventory ranges and stockouts
- Variety of full and blended cartons
- Variety of pallets and truck deliveries
- CO₂ emissions for every retailer and globally
- Carton materials and plastic utilization
- Operator productiveness (orderlines and items per line)

besides Exception as e:

}I used to be fairly happy with Claude’s introduction to the software.
It begins with the introduction of the core capabilities of the instruments from an operational viewpoint.
Rapidly, our director began to ship me lengthy emails with questions on the right way to use the software:
- Methods to arrange the parameters?
- Who ought to I contain on this train?
My preliminary reflex was to reply: “Why don’t you ask Claude?”.
That is what they did, and the outcomes are glorious. Claude proposed a framework of research.
This framework is almost excellent; I might simply have put the lead time (LD) additionally within the scope of the Warehouse Supervisor.
Nonetheless, I have to admit that I might by no means have been capable of generate such a concise and well-formatted framework alone.
Then, Claude proposed a plan for this examine with a number of phases.
Let me take you thru the completely different phases from the consumer’s perspective.
Part 1: Baseline Evaluation
I suggested the staff to repeatedly ask Claude for a pleasant dashboard with a concise govt abstract.
That’s what they did for Part 1.
As you possibly can see within the screenshot above, Claude used the MCP Server software launch_greeninv to run an evaluation with the default parameters outlined within the Pydantic mannequin.
With the outputs, it generated the Government Abstract for our director.
The abstract is concise and straight to the purpose.
It compares the outputs (key efficiency indicators) to the targets shared within the MCP docstring and the grasp immediate.
What concerning the managers?
Then it generated team-specific outputs, together with tables and feedback that clearly highlighted probably the most vital points, as proven within the instance under.
What’s fascinating right here is that our warehouse supervisor solely talked about the goal items per line in a earlier message.
Which means we will have the software be taught not solely from the MCP’s instruments docstrings, grasp immediate, and Pydantic fashions, but in addition from consumer interactions.
Lastly, the software demonstrated its means to have a strategic strategy, offering mid-term projections and alerting on the important thing indicators.
Nonetheless, nothing is ideal.
When you’ve weak prompting, Claude by no means loses the chance to hallucinate and suggest choices outdoors the scope of the examine.
Allow us to proceed the train, following Anthropic’s mannequin, and proceed to Part 2.
Part 2: Situation Planning
After brainstorming with its staff, our director collected a number of eventualities from every supervisor.
What we will see right here is that every supervisor needed to problem the parameters centered on their scope of accountability.
This thought course of is then transcribed into actions.
Claude determined to run the six eventualities listed above.
The problem right here is to compile all the outcomes into an artificial, insight-driven abstract.
Within the case examine printed in 2024, I centered solely on the primary three eventualities, analyzing every efficiency indicator individually.
What about Claude?
Claude was smarter.
Though we had the identical kind of knowledge readily available, it produced one thing extra “cross-functional” and decision-driven.
- We have now business-friendly names for every situation which might be comprehensible throughout features.
- Every situation is linked to the staff that pushed for it.
Lastly, it offered an optimum situation that may be a consensus between the groups.
We’re even supplied with a scorecard that explains to every staff why the situation is finest for everyone.

Conclusion
A brand new hope for the idea of Inexperienced Stock Administration
After a few weeks of experimentation, the Provide Chain Director is satisfied of the necessity to implement Inexperienced Stock Administration.
The one bottleneck right here is on their aspect now.
With Claude’s assist, our 4 managers concerned within the examine understood the influence of their roles on the distribution chain’s general effectivity.
This helps us at LogiGreen onboard Provide Chain departments for complicated optimisation workout routines like this one.
In my view, it’s simpler to conduct a inexperienced transformation when all groups have possession and sponsorship.
And the one strategy to get that’s to ensure all people understands what we’re doing.
Based mostly on the preliminary outcomes of this modest experiment, I believe we’ve discovered a superb software for that.

AI Agent for Provide Chain Community Optimisation
In one other article printed on In the direction of Information Science, I share an analogous experiment centered on the Provide Chain Community Design train.
The target right here is extra macro-level.
We need to decide where items are produced to serve markets on the lowest price in an environmentally pleasant method.
Whereas the algorithm differs, the strategy stays the identical.
We attempt a number of eventualities with parameters that favour completely different groups (finance, sustainability, logistics, manufacturing) to achieve a consensus.
Like right here, Claude does an ideal job in synthesising the outcomes and offering data-driven suggestions.
