Predictika · Cummins C-series diesel generator sets for data centers: capacity, emissions, sound and terms
An AI sales agent prepares a quote for diesel generator sets for a fictional data center. Before it goes out, the agent sends it to Predictika’s validator, which checks it against the sizing, emissions, installation and pricing rules, compares the quote total the agent states with the one it computes, and returns a verdict with every reason.
This validator models Cummins C-series diesel generator set quotes for data centers. It handles any combination of quantity, rating, redundancy, site conditions and use case that the five modeled units can produce, not just the scenarios shown below.
It does not cover non-diesel generation, generator sets outside the five modeled models, real Cummins prices or terms, or applications other than data centers.

What this means
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ or Revenue Cloud) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.
| What the validator catches | Typical rules-based CPQ | Predictika |
|---|---|---|
| Site capacity from rating, derate and redundancy | Only with workarounds Capacity depends on the rating, a derate that combines altitude and temperature, and the units left in service; chaining those into one comparison with the load usually takes several price or validation rules that must run in order. | Each figure is computed once and the capacity check reads them all. |
| Combined sound level across unit count | Only with workarounds The sound level of several identical units adds on a logarithmic scale; a rules-based CPQ usually needs a lookup table kept by hand. | The level per enclosure and the unit-count effect are modeled together and compared with the site limit. |
| Emissions and use-category rules | Only with care Rating and EPA tier restrictions by use category are simple validation rules; keeping them complete as models and tiers are added is the work. | Use, rating, tier and model availability are checked together on every call. |
| Lead time with options | Only with care Lead time that grows with the Tier 4 Final package and sound enclosure needs a rule that reads the chosen options. | Lead time is computed from the model and options and compared with the time available. |
| Discount authority that depends on quantity | Only with care A distributor limit, a quantity-based maximum and an approval step need separate rules. | All thresholds are evaluated together and returned with the reason. |
| The total the agent states | Only with workarounds Comparing a stated total with a computed one means a separate rule per quote layout, and price rules rarely run on stated figures. | The stated quote total is a field in the request and is checked against the computed total. |
| Every problem returned in one answer | Only with workarounds Rules tend to fire as the quote is saved, so a rep often fixes one error and meets the next. | All findings come back together, whatever order the choices arrived in. |
Every rule is checked on every call, in whatever order the choices arrive, and one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.
| Rule | Effect | What it checks |
|---|---|---|
| 1 | computed | Rated kW comes from the ISO 8528 rating: standby, prime or continuous |
| 2 | computed | Derate of 1 percent per 100 m above 1,000 m and 1 percent per degree C above 40 C |
| 3 | computed | Units counted in service by redundancy scheme: N, N+1 or 2N |
| 4 | block | Site capacity must be at least the critical load |
| 5 | needs approval | Derate above 10 percent needs an application engineering review |
| 6 | block | Non-emergency use (demand response, peak shaving) cannot use the standby rating |
| 7 | block | Non-emergency use requires EPA Tier 4 Final emissions |
| 8 | block | The Tier 4 Final package must be offered for the chosen model |
| 9 | block | More than one unit on a bus requires paralleling controls |
| 10 | block | Combined sound level (enclosure level plus the effect of unit count) must not exceed the site limit |
| 11 | block | Fuel tank runtime must cover the required runtime |
| 12 | block | Lead time, including Tier 4 Final and sound enclosure options, must fit the time available |
| 13 | approval, then block | Discount: up to 5 percent distributor authority, approval up to 10 percent (15 percent for four or more units), beyond that blocked |
| 14 | computed | Unit price roll-up from model, options and paralleling, plus startup per unit |
| 15 | block | The quote total the agent states must match the validator total within $1 |
