phytrade 1.3.0

Institutional Physics-based Engine and Protocol for Global Commodity Arbitration

phytrade (v1.2.9)

Institutional Physics Library and Protocol for Global Commodity Arbitration

phytrade is a high-precision computational physics framework designed to resolve mass, quality, and environmental disputes in international trade. By implementing industry-standard thermodynamics, fluid dynamics, and mechanical stress models, it provides an objective "Arbitrator" for maritime and land-based commerce.

🏛️ Project Architecture: The 50-Problem Roadmap

Version 1.2.9 marks the transition from a specialized thermal tool to a comprehensive physics engine. All five core domains are now Active, populating the library with the first 50 essential problem-solvers for global trade.

Category	Domain	Status	Scope
I	Thermodynamics	✅ Active	Problems 1-10 (Moisture, Heat, PCM)
II	Fluid Dynamics	✅ Active	Problems 11-20 (Drag, Cavitation, Siltation)
III	Mechanical	✅ Active	Problems 21-30 (Stress, Torque, Wind Tech)
IV	Logistics	✅ Active	Problems 31-40 (Platooning, Docking, Routing)
V	Strategic	✅ Active	Problems 41-50 (ROI, Risk, Game Theory)

🚀 Key Features (v1.2.9 Expansion)

The library now supports multi-domain arbitration across the following engines:

• Thermo (Category I): Mass Deconvolution (ASABE D245.7), Container Rain Prediction, and Perishable Respiration models.
• Fluids (Category II): Hull Skin Friction analysis for bio-fouling, Propeller Cavitation erosion risk, and Port Siltation depth impact on cargo capacity.
• Mechanical (Category III): Wind-Assisted Propulsion (Sails/Rotors) force calculation, Shaft Torque monitoring, and Hull Stress analysis.
• Logistics (Category IV): Aerodynamic Drafting (Truck/Ship Platooning) fuel savings and optimized Dry-Docking scheduling.
• Strategic (Category V): Economical Speed optimization, Strategic Reserve utilization, and Market Volatility hedging.

##🛠 Usage: The "Any Port" Arbitrator To bypass localized data naming conventions, use the v1.2.9 mapping bridge:

'''bash

from phytrade.engine import Engine from phytrade.schema import Schema from phytrade.mapper import Mapper

1. Initialize the Protocol

schema = Schema() mapper = Mapper() engine = Engine(baseline_entropy=1.5, schema=schema, mapper=mapper)

2. Define Local Port Jargon (e.g., Singapore, Rotterdam, or Chattogram)

local_mapping = { "vessel_displacement": "mass", "current_sog": "velocity", "arrival_delay": "delta_t", "cargo_value_usd": "contract_value" }

3. Raw Telemetry Data

raw_data = { "vessel_displacement": 180000, "current_sog": 24.5, "arrival_delay": 72, "cargo_value_usd": 15000000 }

4. Execute Objective Arbitration

This bypasses human bias by using the laws of physics as the contract base.

mapped_data = {local_mapping[k]: v for k, v in raw_data.items()} result = engine.calculate_dispute_value(**mapped_data)

print(f"Arbitration Status: {result['status']}") print(f"Recommended Settlement: ${result['recommended_settlement_usd']:,.2f}")

📦 Installation

pip install phytrade

🛠️ Usage  
To integrate the arbitration engine into your workflow, initialize the specific domain arbitrator:

from phytrade import ThermoArbitrator, FluidsArbitrator, MechanicalArbitrator

# 1. Initialize the Engines
thermo = ThermoArbitrator()
fluids = FluidsArbitrator()
mech = MechanicalArbitrator()

# 2. Solve a Hull Friction Dispute (Problem 11)
# Estimate drag increase from bio-fouling (15% fouling index) at 12 knots
drag_increase = fluids.estimate_hull_skin_friction(
    velocity=6.17,  # 12 knots in m/s
    wetted_area=3500, 
    bio_fouling_index=0.15
)

# 3. Calculate Wind Propulsion Offset (Problem 19)
wind_force = mech.calculate_wind_propulsion(
    wind_speed=15.0, 
    sail_area=200, 
    angle=45
)

print(f"Added Drag Force: {drag_increase} N")
print(f"Wind Assist Force: {wind_force} N")
