Decision support
Deployment Opportunity Model.
A transparent way to test what a deployment would have to look like at your destination. Every assumption is yours to change, and every number below is derived from those assumptions — not from Knull performance data.
Illustrative only
This tool produces modelled figures from inputs you control. It is not a forecast, a quotation, or a report of observed results. Model version 1.0 — August 2026.
01Your assumptions
Set the inputs.
Total recorded visits to the destination across a year.
Share of eligible visits that actually start a session. Keep this conservative for a first deployment.
Number of trolleys deployed across the destination.
Days the destination is open and the service is live.
Minutes between release and return, including time parked mid-visit.
Hours per trading day the service is available to shoppers.
Illustrative only. Actual pricing is agreed per destination and may be zero where the service is funded by the operator.
02Modelled outcome
What that implies.
- Modelled annual sessions
- 162,000
- Average sessions per day
- 450
- Sessions per trolley per day
- 3.8
- Fleet utilisation
- 23.4%
- Suggested fleet for demand
- 44
- Modelled service value
- 324,000
Sensitivity band (±20% adoption)
129,600 – 194,400 sessions per year
Band shows the modelled range if adoption lands 20% below or above your input; the marker is your current assumption.
Figures are modelled from the inputs above and are illustrative. They do not represent measured Knull performance, a service commitment, or a price.
03Method
Every assumption, stated plainly.
If a number here is going to inform a decision, you should be able to see exactly how it was produced.
Sessions are derived, not observed
Annual sessions = footfall × eligible share × adoption. All three are your inputs; none is a measured Knull figure.
Capacity is theoretical
Daily capacity = fleet × (service hours ÷ average session length). Real capacity is lower because of peak concentration, charging and servicing.
Fleet sizing carries headroom
Suggested fleet serves modelled demand at 65% of theoretical capacity so peak hours are not run at the limit.
Sensitivity band is fixed at ±20%
A deliberately wide band. It is a reminder that adoption is the least certain input, not a statistical confidence interval.
No cost side is modelled
The model deliberately excludes capital, operating and staffing costs, because those are set by the commercial structure agreed for each destination.
04Next step
Have us review your model.
Send the assumptions you have landed on and we will tell you which ones we would challenge, and what a site assessment would need to confirm.
Next step
From model to assessment.
A site walk replaces the assumptions in this tool with facts about your destination.
