An AI sales agent's traveling axle trailer order, checked before it goes out

An AI sales agent prepares an order for a heavy-haul traveling axle trailer with its model, length, axles, crossmembers, tires and options, and states the capacity, deck height and weight it expects. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published equipment list and returns a verdict, every reason and the figures it computed.

Scope: Landoll Model 440 and Model 455 traveling axle trailers: model and length, axles, crossmembers, tires and deck height, capacity and weight, and options. See everything this validator covers

This validator models orders for the Landoll Model 440 (40 ton) and Model 455 (55 ton) traveling axle trailers, not just the scenarios shown below.

  • Model and length — the Model 440 in 41, 45, 48, 50 CA and 53 foot lengths and the Model 455 in 48, 50, 50 CA, 53 and 57 foot lengths, each with its listed estimated empty weight (plus or minus 3 percent).
  • Equipment tied to the model — two 25,000 lb axles with alternating 4 inch and 3 inch crossmembers on the 440, three axles with 4 inch crossmembers on the 455, and the frame capacity (80,000 lb or 110,000 lb) and deck rating (50,000 lb or 70,000 lb in 10 feet) that go with each.
  • Tires, deck height and options — the loaded deck height from the tire size (37 inches on 17.5 inch tires, 5 inches more on 22.5 inch tires), the winch, brake, tire brand, toolbox, finish, color and dock level choices, and a referral to a person for any option that is not on the list.

Any 440 or 455 order that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the sheet lists none, so this validator produces no price build-up or line-item quote), other Landoll trailers, the 215/75R17.5 low-profile tire and dock-level restriction, the dock-level capacity choice, hitch and state weight limits, and options the sheet leaves to the factory. Capacity ratings on the sheet are frame capacities only; actual load capacity depends on axle ratings and regulations, and the validator does not calculate payload.

The AI sales agentBuilds the trailer order from the conversation and says it is ready.

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
Lengths that exist for only one of two modelsOnly with care
Each model has its own list of lengths, so every length is another condition on the model, and the lists change when a new length is added.		Model and length are in one request, so a length the model does not come in is found whichever order the choices arrive in.
A weight the quote states that must fall within the listed toleranceOnly with workarounds
The listed weight depends on the model and the length, and the quote carries a free-entry figure; a rules-based CPQ needs a lookup table, a percentage band and a separate field that stay in step.		The stated weight travels with the order and is compared with the listed estimate, plus or minus 3 percent, on every call.
Deck height that moves with the tire sizeOnly with care
A price or product rule can set the height, but the figure the agent writes in the quote is typed by hand and is not compared with it.		The deck height is computed from the tire size and compared with the figure the quote states.
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.

  

  

    
What this validator catches: findings from its test cases

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 an order for a heavy-haul traveling axle trailer with its model, length, axles, crossmembers, tires and options. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published equipment list and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a Landoll Model 440 traveling axle trailer, 57 foot, with three axles and 4 inch Jr. I-beam crossmembers, a 12,000 lb worm gear winch, 12.25 x 7.5 air brakes, Double Coin 235/75R17.5 tires, non-load-bearing top-opening upper deck toolboxes, and a powder coat finish. The rest of the request is on screen. The quote states a frame capacity of 80,000 lb and a loaded deck height of 37 inches.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The Model 440 is listed in 41, 45, 48, 50 CA and 53 foot lengths; the 57 foot length is listed for the Model 455 only. The Model 440 is listed with two 25,000 lb axles and the Model 455 with three; the axles on the order do not match the model. The Model 440 has alternating 4 inch and 3 inch Jr. I-beam crossmembers on 8 inch centers and the Model 455 has 4 inch Jr. I-beam crossmembers on 8 inch centers; the crossmembers on the order do not match the model.
    6. 
      
  6. The validator returned three 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 lengths that exist for only one of two models, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to Model 455 (55 ton) and the stated frame capacity to 110,000 lb. It sets the stated empty weight to 25,750 lb.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three 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.
