Predictika · Elevator landing door configuration checks

An AI sales agent's landing door order, checked before it goes out

An AI sales agent assembles a landing door order for a new elevator project: the door model, the closing system, the clear opening width and height, the elevator rated speed, the number of elevators and landings, and options such as full glass or an EN 81-58 EI fire rating. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public landing door comparison table and returns a verdict, every reason and the figures it computed.

Scope: Wittur landing doors (Augusta Evo, Hydra, Pegasus, Pegasus Skyline, Pegasus Industrial, Hydra 3000, Nettuno, Luna, Sematic 2000 B-HR): opening size, speed, closing system and options. See everything this validator covers

This validator models the public landing door comparison table for nine door models, not just the scenarios shown below.

  • Opening size — the published clear opening width and height range of each model, for example 600 to 3,200 mm wide and 2,000 to 3,800 mm high on the Pegasus, or 700 to 1,100 mm wide on the Augusta Evo.
  • Speed and closing system — the published elevator speed of each model (for example up to 2 m/s on the Augusta Evo, up to 4 m/s on the Hydra, up to 5 m/s on the Pegasus) and the closing systems each model lists (spring, counterweight, Spirator).
  • Options and door count — whether full glass and the EN 81-58 EI fire rating are listed for the model, and whether the total number of landing doors stated on the order equals elevators times landings.

Any order for these nine door models that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Wittur publishes none, so no price build-up or line-item quote is produced), car doors, drive systems, frames and other accessories. Assumptions: the Pegasus Skyline (listed as over 6 m/s) and the Sematic 2000 B-HR (over 5 m/s) are given no upper speed limit; the Hydra 3000 is read as offering the Spring or Counterweight closing system; full glass on the Sematic 2000 B-HR is listed as optional (limited) and the EI rating is not listed for the Hydra 3000, so both go to a person rather than being blocked.

The AI sales agentBuilds the 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
Options listed for some door models only, such as full glass or the EN 81-58 EI ratingOnly with care
Each option has to be tied to the models that list it, and the table kept in step as the range changes.		The model and every option requested are in one request and compared together on every call.
Opening width and height ranges that differ by modelOnly with care
A width and a height range per model, each with a lower and an upper bound.		The model and the opening are in one request, and every limit is checked on every call.
A stated door count that disagrees with elevators times landingsOnly with workarounds
The total comes from a multiplication; checking a stated figure against it takes extra formulas.		The stated figure is one more field in the request and is compared with the computed total on every call.
A closing system that a model does not listEasy
A compatibility rule between the closing system and the model; routine in a product-rules CPQ.		The same rule, checked together with all the others on every call.
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.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent assembles a landing door order for a new elevator project: the door model, the closing system, the clear opening width and height, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the public landing door comparison table 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 prepare a landing door order for 2 elevators with 6 landings each, using the Wittur Augusta Evo door with the spring closing system. The elevators are rated at 1.6 m/s, and the doors should have full glass panels. 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 clear opening is 1,200 mm; this model goes up to 1,100 mm. Full glass panels are not listed as an option for the quoted door model.
    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 options listed for some door models only, such as full glass or the EN 81-58 EI rating, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the door model to Sematic 2000 B-HR and the clear opening width to 1,100 mm.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Not blocked, but held for a person.
    12. 
      
  12. The two blocking findings are cleared; one approval remains for a person: full glass on the Sematic 2000 B-HR to confirm.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the door model to hydra.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared.
    18. 
      
  18. Two problems caught in one call, fixed in two passes, 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.
