Full Description
If your supply chain, logistics network, or operations are costing more than they should — or you simply need a smarter, data-driven way to make decisions — this service delivers the rigorous mathematical modelling to get you there.
Zinn Digital, based in London, specialises in mathematical optimisation and supply chain analytics. The work goes well beyond plugging numbers into a formula: every model is formulated to reflect the real constraints and trade-offs in your business, solved with appropriate open-source or commercial solvers, validated thoroughly, and delivered as clean, industry-ready code you can actually use.
**What is included across all tiers:**
- Research into your specific problem and domain context
- Data preprocessing and cleaning so the model is fed reliable inputs
- Full model creation — Linear Programming (LP), Mixed Integer Linear Programming (MILP), scheduling, capacity planning, workforce optimisation, multi-objective formulations, heuristics, or dynamic programming as the problem demands
- Model validation and testing to confirm the solution is robust
- Full source code delivered in Python, R, Excel VBA, or Julia — your choice
**Larger tiers additionally include:**
- Performance monitoring so you understand how the model behaves under different conditions
- Formal model documentation making the work transferable to your wider team
- Fine-tuning to sharpen solution quality and push performance further
**Typical problems solved here include:**
Inventory optimisation, vehicle routing and last-mile logistics, warehouse flow, multi-echelon network design, workforce scheduling, production planning, cost-efficiency trade-off analysis, and sensitivity analysis to quantify risk.
**Who this is for:**
Operations managers, supply chain analysts, data teams, consultancies, and founders who need a technically sound optimisation solution but do not have in-house OR (operations research) expertise. This service is equally suited to those validating a concept with a small model and those who need a fully documented, performance-monitored solution ready to hand to a development team.
**How it works:**
After you place your order, share your data, problem description, and any constraints via the order chat. If anything is unclear, the team will follow up before work begins. You receive clean, reproducible code and results — not just equations — with a clear explanation of what the model is doing and why.
Please message before ordering if your problem is unusually complex or involves large-scale data, so scope and timelines can be confirmed upfront.

Frequently Asked Questions
The Starter tier suits small, well-defined problems with one or two scenarios — for example, a single-depot routing problem or a basic inventory model. The Standard tier suits more complex formulations requiring monitoring and documentation. The Premium tier is for large-scope or multi-objective problems where fine-tuning and full documentation are essential. If you are unsure, send a message before ordering and the team will advise.
You will need to share your dataset (spreadsheet, CSV, database export, or similar), a clear description of the problem you are trying to solve, and any constraints or business rules that must be respected. The more context you can provide, the more accurate and useful the model will be. If anything is missing, the team will follow up via order chat.
The model can be delivered in Python, R, Excel VBA, or Julia — whichever you prefer or already use within your team. Please specify your preference when submitting your requirements.
Before delivery, the model is tested against your data to confirm it produces feasible, logical solutions, handles edge cases correctly, and behaves as expected when inputs change. This step ensures you receive a robust result rather than a model that only works under ideal conditions.
Documentation covers the mathematical formulation, the assumptions made, variable and constraint definitions, and guidance on how to update or extend the model. This makes the work transferable to colleagues or developers who were not part of the original engagement.
Fine-tuning involves iterating on the model after initial validation — adjusting solver parameters, constraint tightening, objective weighting, or heuristic design — to improve solution quality and computational performance. It is particularly valuable for large or complex problems where the first feasible solution is rarely the best one.
Yes — cloud deployment is available as an optional add-on. Please add it to your order or discuss requirements via order chat before purchasing, so the correct environment and scope can be confirmed.
You will be asked to share your project details and data via the order chat. The team reviews your submission and may follow up with clarifying questions before work begins. You will receive updates through the order manager and the final deliverables — code, notebooks, and any reports — via the same channel.
