Predictika · Marine propulsion configuration: transmission model, ratio, duty class and engine match

An AI sales agent's Twin Disc MGX-5114 transmission order, checked before it goes out

An AI sales agent prepares a marine transmission order for a boat builder: an MGX-5114 model, a reduction ratio, a duty class, the engine's power and speed, and options such as a PTO or flexible coupling. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published input ratings and optional equipment and returns a verdict, every reason and the rating it computed.

Scope: Twin Disc MGX-5114SC, MGX-5114IV and MGX-5114RV orders: reduction ratio, duty class, engine power and speed against the input ratings, PTO, coupling and housing options. See everything this validator covers

This validator models orders for one transmission series, the Twin Disc MGX-5114, not just the scenarios shown below.

  • Models and ratios — the MGX-5114SC (0.93 to 3.00:1), MGX-5114IV (1.05 to 2.57:1) and MGX-5114RV (1.03 to 2.50:1), each with the reduction ratios listed in the bulletin.
  • Input ratings — the published kW rating for each model, ratio group and duty class (pleasure craft, light, intermediate, medium and continuous duty), the engine power compared with it, and the 450 to 3000 rpm input speed limits (2800 rpm for the 0.93:1 ratio). An engine speed above the speed at which the rating is listed goes to a person for confirmation.
  • Options — live PTO sizes with their maximum torque, the hydraulic clutchable PTO, flexible couplings and the SAE housing (SC and IV only; the RV has the SAE C live PTO option only), and the stated rating compared with the published rating.

Any MGX-5114 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Twin Disc publishes no price list, so this validator produces no price build-up or line-item quote), other Twin Disc transmission series, left-hand rotation engines, controls, oil coolers, mounting brackets, installation and regional terms.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A rating that depends on model, ratio and duty classOnly with workarounds
The permitted power comes from a table keyed by model, ratio group and duty class, so the rules multiply and have to be kept in step with the bulletin.		All the choices arrive together and the rating is looked up from them on every call.
Ratio lists that differ by modelOnly with care
Each model offers its own ratios, so a ratio valid on one model is wrong on another and the lists have to be maintained per model.		The model and ratio arrive together and the ratio is checked against that model's list.
Options available on some models onlyOnly with care
PTO sizes, couplings and housing are listed for some models only, so dependencies between the model and each option need their own rules.		Each option is checked against the model it is ordered with, together with its torque limit.
A rating that needs a person to confirmOnly with care
An engine speed above the one at which the rating is listed is neither allowed nor forbidden; a rules engine tends to treat it as one or the other.		It comes back as an approval item next to the blocking findings.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, 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 any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a marine transmission order for a boat builder: an MGX-5114 model, a reduction ratio, a duty class, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published input ratings and optional equipment and returns a verdict, every reason and the rating it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a Twin Disc MGX-5114SC with the 3.00:1 reduction ratio, rated for pleasure craft, behind an engine of 640 kW at 2,300 rpm, with no PTO. The order states an input rating of 673 kW. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The engine power is 640 kW, but this model, ratio and duty class are rated up to 578 kW at the listed input speed. The order states an input rating of 673 kW, but the model, ratio and duty class are rated 578 kW.
    6. 
      
  6. The validator returned two blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a rating that depends on model, ratio and duty class, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the reduction ratio to 1.50:1.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. Both earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Two problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    14.
