Method & Evidence

AimHow can selective disassembly sequences be optimized to simultaneously maximize profit and minimize disassembly time for end-of-life products?
MethodMetaheuristic optimization (Scatter Search)
ProcedureA multiobjective optimization model was developed to represent the selective disassembly sequence problem. An improved scatter search algorithm was employed, incorporating diversification, crossover, local search, and reference set updates, to find optimal disassembly sequences. The algorithm's performance was evaluated through simulation experiments on various products and compared against a non-dominated sorting genetic algorithm (NSGA-II).

Strengths & Limitations

Strengths

  • +Addresses a critical aspect of sustainable product lifecycle management.
  • +Proposes and validates an effective optimization methodology for a complex problem.

Limitations

Real-world disassembly can be unpredictable due to wear and tear, damage, or variations in product assembly. The computational complexity of these optimization models can also be a limitation for very large or complex products.

Reliability & validity

The study's validity is supported by comparing its method to a well-established algorithm (NSGA-II) and conducting simulations on different products. Reliability would depend on the reproducibility of the scatter search algorithm's results.

Think critically

How might the 'profit' and 'time' objectives in disassembly be weighted differently depending on the type of product or the company's strategic goals?
