FactoryOS — Capacity & ILUO Planner Pro

Advanced Production Capacity Planning & Overtime Optimization in Excel

Realistic Capacity Based on Workforce, Machines, OEE, and Absenteeism — Not Theoretical Assumptions

Stop Planning on Nominal Hours. Start Planning on Effective Capacity.

Most capacity planning spreadsheets calculate theoretical hours.
Factories do not run on theory.

FactoryOS Capacity & ILUO Planner Pro is a professional-grade Capacity Planning Excel template designed to model how production actually behaves on the shop floor.

It converts workforce, shifts, and machines into gross capacity — then systematically removes:

• Absenteeism

• Planned downtime

• Planned OEE losses

The result is true effective capacity — the only number that matters in real operations.

What Makes This Capacity Planning Tool Different?

Traditional planners assume 100% attendance and perfect efficiency.

This model applies an operational lens by integrating:

• Workforce-based capacity modeling

• Machine constraints

• Attendance loss modeling

• OEE-adjusted productive time

• Demand comparison and utilization analysis

• Structured overtime decision logic

It is not just a production capacity calculator.
It is a decision-support system for operations leaders.

Core Capabilities

👷 Workforce & Machine-Based Capacity Modeling

The planner converts:

• Number of operators

• Shift structure

• Shift duration

• Number of machines

into structured gross available hours.

It supports environments where capacity is:

• Labor-constrained

• Machine-constrained

• Or mixed-constraint systems

This makes it ideal for manufacturing lines, cells, and discrete production environments.

📉 Effective Capacity After Real-World Losses

The model automatically adjusts gross capacity by removing:

• Absenteeism rate

• Planned downtime

• Planned OEE performance losses

This produces Net Effective Capacity, aligned with real operational behavior.

Instead of inflated planning numbers, you get a realistic production capability forecast.

Perfect for OEE-based capacity planning and operational review meetings.

⚖️ Capacity vs Demand & Utilization Analysis

The planner compares effective capacity against demand and calculates:

• Utilization percentage

• Capacity surplus or shortfall

• Clear quantified capacity gap

This enables production planners to immediately identify whether they are:

• Underutilized

• Balanced

• Or facing overload risk

It functions as a structured Utilization Analysis Excel tool for weekly or monthly planning cycles.

⏰ Intelligent Overtime Planning Engine

When a capacity gap exists, the tool calculates:

• Overtime hours required

• Coverage percentage

• Day-equivalent overtime requirement

• Structured recommendation

Instead of guessing how many extra hours are needed, you receive a data-driven answer.

This makes it a practical Overtime Planning Tool for Manufacturing, ideal for line-level decisions and S&OP discussions.

🚦 Scenario-Based Capacity Status

The planner automatically evaluates and categorizes the situation as:

• Sufficient Capacity

• Tight Capacity

• Insufficient Capacity

It also allows scenario testing under:

• Normal conditions

• High-demand situations

• Reduced-attendance environments

This enables risk analysis and contingency planning before problems occur.

ILUO Logic — Structured Capacity Thinking

The embedded ILUO logic (Installed, Loaded, Utilized, Overtime) ensures that capacity evaluation follows a disciplined hierarchy:

1. Installed Capacity

2. Effective Loaded Capacity

3. Utilized Capacity

4. Overtime Requirement

This structured approach aligns with professional operations management methodology and supports clearer executive communication.

Business Impact

When applied consistently, structured capacity planning can:

• Reduce last-minute overtime decisions

• Prevent line overload and burnout

• Improve delivery reliability

• Support S&OP alignment

• Increase cost transparency

• Strengthen production meeting discipline

FactoryOS Capacity & ILUO Planner Pro transforms capacity planning from reactive firefighting into proactive operational control.

Designed for Real Manufacturing Environments

This template is ideal for:

• Production Planners

• Operations Managers

• Manufacturing Engineers

• Line Leaders

• Plant Managers

• Continuous Improvement Teams

Especially in environments where workforce variability and OEE losses significantly impact output.

Why Excel?

Because Excel is:

• Widely available across organizations

• Transparent and auditable

• Easy to deploy without IT barriers

• Flexible for scenario modeling

This is a Manufacturing Capacity Planning Excel solution without macros or hidden logic — fully visible, fully adaptable.

Make Capacity Visible. Make Overtime Predictable.

FactoryOS Capacity & ILUO Planner Pro delivers:

• Realistic effective capacity modeling

• Demand vs capacity clarity

• Utilization transparency

• Structured overtime recommendations

• Scenario-based risk visibility

Plan capacity the way the shop floor actually operates — not the way textbooks describe it.
