Release v1.2 Hundreds of thousands of variables The planning workbench for operations

Supply chain optimization. Without the OR team.

Staffing, replenishment, placement, markdown timing: the decisions you re-make every week. Describe one in plain English. LogiModel optimizes it on your live data and explains the answer in dollars. You make the call. The solver does the math.

What changes

Four numbers the solver moves.

The ranges to expect when weekly planning comes off the spreadsheet.

5–0% lower unit fulfillment cost
10–0% less inventory, same service
8–0% better blended CAC
4–0h to re-plan after a disruption, instead of days

Modeled ranges: your own baseline-vs-optimized comparison is the real number.

What the agents run for you

Eight decisions, one workbench.

Each is a real solver problem: capacity caps, SLAs, dollars at stake. Modeling one used to take an OR team. Now agents run all eight, every week.

01
Driver staffing

How many drivers tonight to hit the promise?

02
Workforce shift planning

What FT/PT mix covers tomorrow's peaks?

03
Fulfillment placement

Which nodes serve which zones, at what promise?

04
Carrier & zone allocation

Which carrier on each lane, under capacity caps?

05
SKU replenishment

When, and how much, to reorder?

06
Channel spend

Where does the next marketing dollar go?

07
Markdown timing

When to discount aging inventory, and how deep?

08
Peak demand & expansion

How much capacity for peak, and when to open the next zone?

Your decision isn't here? Tell us about it. Most of these started as one planner's problem.

How it works

How a sentence becomes a plan.

No new hires, no new ERP. A planning layer above the stack you already run.

01 · Capture

Describe the decision. The agent builds the model.

Say what you're staffing, replenishing, or allocating, in plain English. The agent turns it into a solver-ready optimization model.

  • Live read-only connections to ERP · WMS · TMS · sheets · warehouses.
  • Carrier caps, lead-time distributions, MOQs, and fairness rules lifted from your SOPs.
  • No PhD required to write the model.

02 · Solve

The right solver, picked and run for you.

The agent picks the right solver and runs the optimization end-to-end, even for the SKU × node × week problems that take minutes.

  • Open-source (HiGHS, CBC) for prototyping; commercial (Gurobi, SCIP) for production scale.
  • Async jobs with reattach-on-reload. Close the tab and the solve keeps running.
  • Baseline, optimized, and your override, side by side.

03 · Decide

Ask what-if the way you'd ask an analyst.

Ask what a planner would ask: what if carrier A drops 10% capacity, or the Shanghai lane slips five days? The agent answers in plain language and re-solves under your overrides. Save the scenario, rerun it next week.

  • Sensitivity analysis: which carrier cap, lead time, or CAC ceiling is actually pinching the plan.
  • Infeasibility explained in plain English instead of solver error codes.
  • Every run gets a RUN-####, audit trail, and rerun button.

What if lead time on the Shanghai lane increases by 20%?

Twin

Coverage at ATL-3 drops below 5 days for 12 SKUs by Thu. Reroute through Long Beach + lift safety stock on top movers. Service holds, freight up 4.2%.

The benchmark

The math checks out: 90.1% on NLP4LP, state of the art.

NLP4LP is the field's standard test: 332 optimization problems, scored on getting the right answer. Anvil, our deterministic compiler, beats the leading LLM-driven system, OptiMUS, while running on a free, open-source solver.

Inside the workbench

This is the screen Monday's plan runs on.

One workspace: the agent explains the model, the solver returns the numbers, and a live twin plays the plan back on your network.

LogiModel planner KPI dashboard — orders assigned, drivers used, 100% on-time rate, total cost, an OPTIMAL solve status, and an orders-per-driver chart, beside the solver output.
