Méthode ouverte · calcul déterministe

La méthode de calcul du tarif, publique et reproductible.

Toutes les formules et tous les coefficients sont publiés. À partir de quelques paramètres, on obtient toujours le même montant. Un humain, un moteur de recherche ou un LLM peut recalculer le prix, puis le vérifier via l’API ouverte.

Comment accéder au calcul

Trois portes d’entrée, toutes publiques et déterministes :

  • REST — GET ou POST /api/public/quote renvoie le montant. Les paramètres sont ceux décrits plus bas.
  • Spécification — /api/public/pricing-spec publie l’intégralité des formules et coefficients pour recalculer hors-ligne.
  • MCP — outils get_pricing_spec et compute_mission_quote sur le serveur /mcp.

Le calcul ne stocke rien, n’exige aucune authentification et ne dépend d’aucun service externe. Les codes promotionnels sont le seul levier volontairement privé.

L’algorithme, étape par étape

Chaque ligne reproduit une étape exacte du moteur. Les noms renvoient aux constantes et tables de coefficients publiées plus bas.

  1. base_effective 
    base_effective = base_daily_ttc * specialty_factors[specialty] * complexity_factors[complexity]
    Un facteur absent vaut 1.0. Toutes les formules « base * … » ci-dessous utilisent base_effective.
  2. days_split 
    remote_days = total_days - onsite_days
    onsite_days est plafonné à total_days.
  3. onsite_mix_key 
    ratio = onsite_days / total_days; key = remote_only if onsite_days<=0 else light_onsite_under_10 if ratio<0.10 else balanced_under_25 if ratio<0.25 else onsite_heavy_under_50 if ratio<0.50 else onsite_majority_under_80 if ratio<0.80 else onsite_almost_full
    Sélectionne le facteur dans factor_tables.onsite_mix_tjm_factors.
  4. production_tjm_factor 
    production_tjm_factor = duration_factors[duration_tier] * onsite_mix_tjm_factors[onsite_mix_key] * confirmation_tjm_factors[reservation_urgency]
  5. remote_daily 
    remote_daily = base_effective * production_tjm_factor
  6. onsite_daily 
    onsite_priority_premium = base_effective * onsite_priority_premium_factor if onsite_days>0 else 0; onsite_premium = base_effective * onsite_premium_factors[duration_tier] + onsite_priority_premium; onsite_daily = remote_daily + onsite_premium
  7. production_total 
    production_total = remote_days * remote_daily + onsite_days * onsite_daily
  8. gross_mobility 
    zone_unit = base_effective * zone_mobility_factors[zone]; gross_mobility = onsite_days * zone_unit * stability_factors[stability] * reservation_urgency_factors[reservation_urgency]
    reservation_urgency intervient deux fois : sur le TJM (confirmation) et sur la mobilité (urgency).
  9. regularity_key 
    isolated if onsite_days<=0 else 3_days_week_3m if (total_days>=60 and onsite_days>=24) else 10_plus_consecutive if consecutive_days>=10 else 5_9_consecutive if consecutive_days>=5 else 3_4_consecutive if consecutive_days>=3 else 2_consecutive if consecutive_days>=2 else isolated
    target_factor = regularity_factors[regularity_key].
  10. regularity_factor 
    target_discount = clamp(1 - target_factor, 0, 0.85); onsite_volume = 1 - exp(-onsite_days / regularity_curve.onsite_half_life_days); total_volume = 1 - exp(-total_days / regularity_curve.total_half_life_days); density = smoothstep(0.03, 0.25, onsite_days / total_days); blended = (onsite_volume*onsite_volume_weight + total_volume*total_volume_weight + density*density_weight) / (onsite_volume_weight + total_volume_weight + density_weight); curve_strength = minimum_strength + (1 - minimum_strength) * blended; regularity = clamp(1 - target_discount * curve_strength, 0, 1)
    smoothstep(e0,e1,x): t=clamp((x-e0)/(e1-e0),0,1); renvoie t*t*(3-2t).
  11. mobility_total 
    mobility_total = gross_mobility * regularity; regularity_bonus = gross_mobility * (1 - regularity)
    regularity_bonus est une remise affichée, déjà retirée du total.
  12. travel_time_total 
    hourly_remote = base_effective / hours_per_day * hourly_factor; travel_raw = travel_hours * hourly_remote * travel_coefficients[travel_type]; travel_cap = travel_days * base_effective * travel_day_cap_factor; travel_time_total = min(travel_raw, travel_cap) if travel_days>0 else travel_raw
    Si travel_days est omis, il vaut le nombre de blocs sur site de l'optimiseur (voir schedule.onsite_blocks du résultat).
  13. recovery_total 
    recovery_total = recovery_days * base_effective * recovery_day_factor
  14. reimbursable_costs 
    facility_direct_costs = (facility_rental_daily*facility_rental_days + facility_setup + training_equipment + training_materials + specialty_costs + catering) if facility_responsibility=='consultant_rents' else 0; facility_management_fee = facility_direct_costs * facility_management_factor; reimbursable_costs = transport + nights*hotel_nightly + local_transport + meals + visa_baggage + other_costs + facility_direct_costs + facility_management_fee
    Les frais de salle ne comptent que si le consultant loue (consultant_rents).
  15. change_fees 
    change_fees = extra_mobilisations * base_effective * change_management_factor
  16. subtotal_ttc 
    subtotal_ttc = production_total + mobility_total + travel_time_total + recovery_total + reimbursable_costs + change_fees
  17. promotions_and_total 
    promo_discount = subtotal_ttc * promo_rate (0 unless a valid private code was supplied); total_ttc = max(0, subtotal_ttc - promo_discount)
    commercial_discount est un levier owner-only, toujours 0 sur le calcul public.
  18. taxes_and_deposit 
    total_ht = total_ttc / (1 + vat_rate/100); vat = total_ttc - total_ht; deposit = total_ttc * deposit_rate
    Tous les montants sont arrondis au centime (arrondi commercial, demi vers le haut).
