Complete Anno 117: Pax Romana Resource Management Guide

Production ratios form the backbone of economic efficiency in Anno 117: Pax Romana. These ratios represent the optimal number of buildings needed in a supply chain to ensure 100% efficiency, with the fundamental unit being the talentum (1t) representing one unit of goods.

Mastering perfect production ratios prevents bottlenecks and idle buildings while maximizing output and minimizing workforce and resource consumption. Whether you're building a thriving Roman empire in Latium or establishing Celtic settlements in Albion, understanding these ratios transforms your gameplay from resource struggle to satisfying logistical planning.

Key Terminology & Unit Definitions

The Talentum System

The talentum (abbreviated as '1t') is the fundamental unit of measurement for goods and resources in Anno 117: Pax Romana. Every production building has a specific production time for creating exactly 1t of its designated good.

Production Cycle Time: The fixed duration a building requires to complete one full production cycle and output exactly 1t. Production ratios are calculated by comparing these cycle times to create balanced supply chains.

Efficiency: This modifies production time per unit rather than output quantity. At 150% efficiency, a building produces 1t every 40 seconds instead of 60 seconds, directly impacting your ratio calculations.

1t (One Talentum): The basic production unit that represents a single item of output from any production building.

The talentum system standardizes measurement across all goods
Ratio calculations match supplier production time to processor consumption time
Unbalanced talentum production causes raw material pile-up or processing building idleness

Production Ratio Calculation Method

Ratio Derivation Process:

Identify cycle times for each building in the chain (e.g., Building A: 30s/1t, Building B: 60s/1t)
Calculate relative speeds (Building A produces 2x faster than Building B)
Apply inverse proportion (Need 2:1 ratio A:B to maintain balance)
Verify efficiency (All buildings operate at 100% with no idle time)

Understanding Production Ratio Fundamentals

Why Perfect Ratios Matter

Perfect production ratios can improve city efficiency tenfold by optimizing workforce and building space. They ensure:

• No building idle time: Prevents processing buildings from sitting idle due to lack of raw materials • Eliminates waste: Stops overproduction of raw materials that clutter storage • Maintains happiness: Ensures consistent supply of essential goods like food and tools • Stable growth: Provides predictable foundation for expanding infrastructure and populations

Inefficient ratios cause bottlenecks where downstream factories sit idle because upstream buildings cannot produce materials fast enough. This leads to shortages that cause population happiness to plummet.

Overbuilding raw material producers creates waste through stockpiles of unused resources, wasting valuable workforce and storage space.

Calculating Perfect Ratios

Perfect ratios are determined by comparing production and consumption cycle times:

Example Calculation: If one building produces 1t every 30 seconds and another consumes 1t every 60 seconds, you need a 2:1 ratio to maintain balance.

This mathematical approach ensures that for every production cycle completed by your upstream buildings, your downstream buildings can consume the exact amount produced, preventing both shortages and surpluses.

Luxury Goods & Cross-Region Production

Managing Inter-Regional Trade Routes

Trade Route Management: Accessed by pressing the 'T' key to create routes with multiple waypoints and specify cargo operations for efficient resource distribution.

Optimal Trade Route Strategies

Hub-and-Spoke System: Designate one central island as a hub to collect surplus goods from surrounding spoke islands for efficient distribution to consumer destinations.

Circular Trade Routes: Collect from production islands and distribute to multiple consumer islands. These routes are more efficient than individual point-to-point connections.

Production Monitoring

Monitor warehouse levels using the trade route manager to identify:

Empty warehouses signal production shortages requiring immediate attention
Full warehouses indicate overproduction that may need route adjustment
Route optimization based on these signals prevents costly overbuilding

Cross-Region Production Optimization

Wine and Spices Dependency: These luxury goods cannot be produced in Albion and must be imported from Latium province, requiring careful trade route planning between regions.

Raw Material Shipping: Cross-region optimization involves shipping raw materials from Albion to Latium for processing into higher-value luxury goods, utilizing both regions effectively in production chains.

Protecting Your Trade Network

Route Security: Protect trade routes from pirates or hostile factions by assigning naval patrols or escort vessels to key shipping lanes during vulnerable periods.

Economic Timing: Avoid early over-investment in expensive steam cargo ships. Use smaller vessels until economy is established with treasury surplus exceeding +10,000 credits or 2000 investors for sustainable expansion.

Advanced Optimization Strategies

Layout and Logistics Optimization

Clustered Production: Layout optimization involves clustering related production buildings together to minimize transportation time between raw material producers and processors, reducing worker travel time.

Strategic Warehouse Placement

Multiple Warehouse Strategy: Advanced logistics includes using multiple warehouses strategically placed to serve production clusters and reduce worker travel time across your settlements.

Production Monitoring: Monitor warehouse levels using trade route manager to identify production shortages (empty warehouses) or overproduction (full warehouses) for strategic route adjustments.

Workforce Management for Production

Population Tier System: Population in Anno 117 is stratified into tiers where each tier provides a different type of workforce required for specific production buildings. Higher-tier populations provide specialized workforces necessary for more advanced production chains.

Population Growth Mechanics

Growth Stages: Population growth works in stages: meet residents' needs, upgrade their homes, and unlock the next tier of specialized workforce.

Positive Feedback Loop: Population growth creates a positive feedback loop where larger population provides more workforce, enabling more production buildings to satisfy even larger population demands.

Strategic Workforce Distribution

Labor Monitoring: Strategic workforce distribution involves monitoring labor requirements against available workforce from each population tier to avoid shortages that halt production.

Specialist Activation: Activating key specialists can significantly boost production building output, maximizing workforce effectiveness during critical expansion phases.

Silent Collapse Prevention: Proactive monitoring of workforce distribution across all islands is essential to prevent "silent collapse" in late-game production chains.

Critical Sector Protection: Workforce shortages in critical sectors like mining can trigger catastrophic failure across multiple advanced production chains in late game scenarios.

Efficiency Calculations with Different Percentages

Efficiency Impact Examples:

100% Efficiency: Standard production time (e.g., 60s/1t)
125% Efficiency: Production time reduced by 25% (e.g., 48s/1t)
150% Efficiency: Production time reduced by 33% (e.g., 40s/1t)
200% Efficiency: Production time halved (e.g., 30s/1t)

Calculation Formula: New Production Time = Base Time / (Efficiency Percentage / 100)

Example: A building with 60s base time at 150% efficiency produces every 60 / 1.5 = 40 seconds
