LEAN Toolboxby Availix · Interactive LEAN tools

Purpose and method

Distribute sequential work elements between stations while respecting takt and task dependencies.

When to use it

Use line balancing for serial flow where station workloads should be even and precedence constraints matter.

Core principle

A mathematically balanced line is not automatically robust. The assignment must respect precedence, variability, skills, equipment, ergonomics and recovery capacity.

What the interactive module provides

  • Station assignment
  • Efficiency and idle time
  • Current and future-state comparison
  • station assignment, cycle comparison, efficiency, idle time and unresolved constraints
Professional verification: The module supports learning, analysis and documentation. Verify results against actual process conditions, internal standards, safety requirements and competent professional judgement before implementation.
01

Recommended workflow

Assign work elements to stations under takt, precedence and capability constraints, then compare efficiency, idle time and bottleneck risk.

  1. 1

    Calculate takt from valid demand and net time

  2. 2

    Define work elements, times and precedence

  3. 3

    Record fixed and variable station capabilities

  4. 4

    Create and compare feasible assignments

  5. 5

    Validate the selected balance under real variability

02

Practical example

A seven-station line meets average takt but one station repeatedly exceeds it because two variable manual tasks are combined. Separating one task reduces queue formation.

Calculation or verification principle

Minimum theoretical stations = total work content ÷ takt, rounded up. Line efficiency = total work content ÷ (stations × maximum station time) × 100%.

Frequently asked questions

What data do I need to use this tool?

Prepare demand, net available time, work elements, times, precedence, station capabilities and assignment constraints.

What result does the module produce?

The module produces station assignment, cycle comparison, efficiency, idle time and unresolved constraints.

Can I implement the result without further review?

No. Treat the output as a structured engineering and improvement aid. Verify source data, assumptions, safety, quality, legal requirements and local process conditions with competent responsible people before implementation.
