Supply chain optimization sets what a network carries, where it carries it and how fast. Three patterns bend the target before the arithmetic starts.
01
The target comes from shipments
Own shipment history supplies the demand series the network optimizes toward. It records what a company managed to sell in the markets it already serves, filtered through whatever sat in the outlet at the time.
A sell-out week reads as a demand ceiling.
Cost falls while unmet demand holds steady.
02
Sight ends at the shipment
The record runs to the point of dispatch, and the trail goes quiet after it. What the outlet held on the day and what the buyer took home arrive later, as a partner report compiled by the partner.
Demand that met an empty outlet sits off the record.
A service level of 96% describes the order and the outlet separately.
03
One figure per market
A single demand figure covers a market where formats, outlet types, and price tiers move in different directions. The parts cancel inside the total, and the network optimizes toward an average that sits away from every segment underneath it.
A climbing format sits hidden behind a falling one.
Route and cover follow a figure the mix has left behind.
Sena is the decision AI with access to real-world data. It counts what consumers across a market purchased and records what each outlet held on the day, so the demand side of an optimization rests on the category itself.
01
Demand counted at the buyer
Sena counts category purchases across the market, including purchases made from every other player, so the series behind a target describes what buyers did.
Every player in the category counted, market by market.
Met demand and unfilled demand kept separate.
02
Availability read in the outlet
Contributors record what each outlet held and which lines had gone, dated to the day of capture.
Presence per outlet, market and line.
Every availability figure carrying its outlet photograph.
03
Markets ranked by movement
Sena reports how fast recorded purchases moved in each market, indexed against the others, so route and cover follow demand a team can open.
An optimization holds up on two things: whether the demand series it runs toward measures the category or one company's shipments, and whether availability was recorded apart from wanting.
Supply chain optimization explained
The demand target decides most of the answer
Supply chain optimization sets the cost, the flow and the service level a network runs at, against a demand target for a named market and period. A network optimized toward a shipment series inherits every stockout, every listing gap and every promotion that shaped those shipments, and carries all of them forward as though buyers wanted that much.
01
Shipments describe supply meeting demand
Complete, internal, and shaped by whatever sat in the outlet.
02
Category purchase describes demand
Every player counted, per market, with availability recorded beside it.
The three optimization layers
Three layers cover most of what runs in practice, and each takes the same demand input.
Layer 01
Network
Where production, holding, and consolidation sit, and which route serves which market. Set once a cycle, and expensive to revisit.
Layer 02
Planning
How much to make and hold per period, per market, and per line. Revisited monthly or weekly.
Layer 03
Execution
Order sizing, cover levels, and replenishment against the plan. Revisited each cycle.
All three run toward a demand figure, and it is usually the same figure. An error in it propagates through every layer at once.
The models behind an optimum
Four families of methods sit under the three layers, and each one takes a demand figure as a parameter.
01
Linear and mixed-integer programming
States the network as an objective function with constraints, then solves for the lowest cost meeting them. Exact within its own terms, and every term arrives from an input.
02
Simulation
Runs the network forward many times against varying conditions and reports the spread of outcomes. Handles variability well and inherits whatever demand spread it was given.
03
Heuristics and rules
Reorder points, min-max levels, and allocation ratios. Fast, transparent, and widely used, with the demand assumption sitting inside the parameter.
04
Machine learning on the operational series
Learns patterns from history and projects them forward. Strong where the future resembles the past, and it learns the constraints alongside the demand.
Where the objectives conflict
An optimization runs against an objective, and the common ones pull apart.
Objective
What it pushes toward
What it trades away
Lowest landed cost
Fewer locations, larger runs, longer routes.
Speed of response when a market turns.
Highest service level
More cover, held closer to the buyer.
Working capital and obsolescence exposure.
Lowest working capital
Leaner cover, later commitment.
Availability in the markets moving fastest.
Lowest emissions
Shorter routes, consolidated movement, local supply.
Flexibility across markets.
Where demand input comes from
Four sources supply the demand target in practice, and each carries a known limit.
01
Shipment history
Fast, complete, and internal. It records supply meeting demand, so it inherits every constraint that shaped it.
02
Partner and channel reports
Closer to the buyer, compiled by the party being measured, covering the markets that party already reports on.
03
Point of sale
Real movement, covering the outlets a company already reaches, which leaves the rest of the market dark.
04
Consumer-measured
Category purchases counted across every player per market, with what the outlet held recorded beside it.
Four inputs behind the target
The demand series comes from four collected inputs, applied per market.
Input
What it answers
Receipts
Category purchases and their dates, so the target counts demand every player met.
Store captures
What each outlet held on the day, which separates a demand fall from an availability gap.
Geo-verified photos
The outlet as the capture found it, with the market and the date attached.
Stated preference
What buyers say they move to when a line has gone, which prices what a gap costs.
What a target must carry
Four things decide whether an optimum survives contact with the market.
The series measures the right thing.Category purchase describes demand. Shipments describe supply meeting demand.
The level matches the decision.A figure accurate at the market level can be wrong at every format inside it, and route and cover run against formats.
Availability stays separable.A flat week caused by an empty outlet asks for a supply answer. A flat week of soft wanting asks for a different one.
The market coverage is honest.A target built on the outlets a company already reaches optimizes the part of the market it already holds.
Where the demand side ends
Sena reports the demand side and the availability side. Freight, lead times, supplier operations, and stock policy stay with the planning and execution systems, and Sena sets its answer beside them. The split earns its place because an optimization that reads a supply gap as soft demand corrects in the wrong direction and then compounds it.
Direct from real consumers
Shared under explicit consent
Real people share what they buy and prefer, under explicit consent. Sena captures it directly at the source, so every figure traces back to where it came from whenever a number comes under question.

Service level sits at 96% across three markets, and sell-through is soft in two of them. Where is the demand?
The product reached the outlets in all three markets, and the capture runs record it sitting there. Recorded purchases in the two soft markets moved toward a smaller pack at a lower price per unit, where the network carries the larger format. The larger format ran absent across a run of captures in one outlet type earlier in the period, and buyers who switched then have stayed switched. The third market holds the original mix and its run rate is steady. Against demand recorded this cycle, cover in the two soft markets sits on the format buyers left.

Figures in this exchange are illustrative.
01
Demand apart from availability
Sena records what sat in the outlet, so an empty slot and soft wanting read as separate causes.
02
Each market has its own rate
Sena indexes recorded movement per market, so route and cover follow the markets taking the category fastest.
03
Open a target to purchase
Any point in the demand series opens to the weeks of purchase and the outlet photographs that produced it.
An optimum carries weight only as far as the demand series underneath it, and most series measure supply meeting demand. Sena builds every figure from real-world signal captured when the question needs it, from consumers purchasing across the category through to the dated capture a service level review is checked against.
01
Consumer activity
Counts what buyers purchased across the category and when, including purchases made from every other player, so the demand target describes the market.
02
Computer vision
Reads what each outlet held off images captured in real outlets, which is what separates an availability gap from a fall in wanting.
03
Zero-party data
Signal arrives from the consumer network under explicit consent. What buyers move to when a line has gone is stated by those buyers.
04
Connect the systems
Shipment history, service level exports, and cover models join over 250+ integrations, so own movement reads against the category around it.
05
Trace every answer
Every point in the series holds its market and its capture date, so a target reopens on the evidence it was built from.
06
From files to databases
Historic movement exports and planning models become one base, so every period the team has measured sits together.
Most optimizations run toward the one demand series a company holds in full, which is its own shipment history. Sena measures the category that history sits inside.

FAQ
Supply chain optimization questions
01 What is supply chain optimization?
Supply chain optimization tunes what a network costs, how fast it flows and what service it holds, against a demand target set for one market and one period. It covers three layers: where production and holding sit, how much to make and hold per period, and how orders and cover run against the plan. The demand target feeds all three.
02 How do teams optimize a supply chain?
By fixing the demand target first, then working the three layers against it. Network decisions set where holding and route sit. Planning sets volume per market and per line. Execution sets order sizing and cover. Sena supplies the demand target from category purchase counted across every player, with what each outlet held recorded beside it.
03 What are the layers of supply chain optimization?
Network optimization places production, holding and route, and is revisited once a cycle. Planning optimization sets what to make and hold per period, per market and per line, and is revisited monthly or weekly. Execution optimization sets order sizes and cover levels against the plan and runs each cycle. All three take the same demand figure, so an error in it reaches every layer.
04 What data is used for supply chain optimization?
Four sources supply the demand target in practice. Shipment history is complete and internal, and it records supply meeting demand. Partner reports are closer to the buyer and compiled by the party being measured. Point of sale covers the outlets a company already reaches. Consumer-measured demand counts category purchases across every player per market.
05 What is the difference between supply chain optimization and supply chain planning?
Planning is one layer inside optimization. Planning decides how much to make and hold per period, per market and per line. Optimization spans that alongside the network layer above it and the execution layer below it. A plan can be optimal against its own demand figure while the network underneath it serves the wrong markets.
06 Why do supply chain optimizations fail?
Most often because the demand series behind them records supply meeting demand, so every stockout and listing gap carries forward as though buyers wanted less. The second cause is aggregation: formats and outlet types moving in opposite directions cancel inside one market total, and route and cover follow an average that sits away from both.
07 How does consumer demand data improve supply chain optimization?
It changes what the target measures. Category purchase counted across every player describes the market, where shipment history describes one company's supply meeting demand. Recording what each outlet held on the same day keeps an availability gap separable from soft wanting, so a supply answer and a demand answer stay apart.
08 Does Sena cover suppliers, freight, and lead times?
Sena works the consumer end of the chain: demand, availability, and what reached the buyer. Freight, lead times, supplier operations and stock policy remain the work of the planning and execution systems, with Sena's answer sitting alongside. The boundary is deliberate, since the demand side is where a capture at the outlet carries evidence.
09 What data does Sena use for supply chain optimization?
Recorded category purchase from consumers in the markets named, contributed under explicit consent by a 5M+ network reaching 190+ countries. Store captures sit beside it, holding what each outlet had on the day, which keeps availability and wanting separable. Shipment history, service level exports and cover models connect through 250+ integrations for comparison.
