Assembly line balancing problem

As explained in Optimization Algorithms: AI techniques for design, planning, and control problems

An assembly line balancing problem assigns production tasks to workstations while satisfying constraints and optimizing measures such as station count, cycle time, or idle time.

The assembly line balancing problem (ALBP) assigns production tasks to workstations while respecting constraints and reducing idle time. It also covers decisions about cycle time, station count, equipment, task assignment, and operation sequence before production begins. section 6.6

Bicycle assembly line

A five-station bicycle line illustrates the idea: stations successively install the frame, forks and handlebars, wheels, drivetrain components, and seat and accessories. A precedence diagram determines which tasks can follow others, while station workloads must fit the cycle time. section 6.6

Common ALBP distinctions include:

  • SALBP handles one product on a serial line with one-sided workstations; GALBP includes mixed-model, parallel, U-shaped, and two-sided lines. section 6.6

A tabu-search implementation loads task durations and precedence data, sets a cycle time, initializes a solution, and iterates with tenure and iteration limits. Results can be assessed using workstation count, workloads, and smoothing index.

How Optimization Algorithms: AI techniques for design, planning, and control problems covers it

How deep it goes
Explains classifications, objectives, precedence, and tabu-search implementation, then stops short of formal optimization derivations.
Examples
Uses a bicycle assembly line, precedence diagrams, Python data files, workstation workloads, and smoothing-index outputs.
What it assumes
Assumes task durations, precedence relationships, and cycle time while defining their role in line balancing.
What you can do after
Apply tabu search via Python to assign tasks and evaluate workstation counts, workloads, and smoothing index.
How it connects
Connects workstation assignment with cycle time, precedence constraints, combinatorial optimization, and tabu search.
