Disassembly line balancing problem: a review of the state of the art and future directions

Abstract

The disassembly line balancing (DLB) problem assigns the set of tasks to each workstation for each product to be disassembled and aims at attaining several objectives, such as minimising the number of workstations, ensuring similar idle time at each workstation and removing hazardous parts/highly demanded components at the earliest moments possible. Over the past two decades, the DLB problem and its variants have grown ever more popular for researchers and practitioners of environmentally conscious manufacturing. Yet, the problem characteristics and assumptions vary widely and there is no literature review to classify the existing articles accordingly. Hence, a comprehensive literature review of recent and state-of-the-art papers is vital to draw a framework of the past, and to shed light on future directions. To do so, 116 studies published in proceedings and journals since 1999 are selected and reviewed. The papers are then analysed and categorised to construct a useful foundation of past research. Finally, trends and gaps in the literature are identified to clarify and to suggest future research opportunities.

Evaluation of Waste Electronic Product Trade-in Strategies in Predictive Twin Disassembly Systems in the Era of Blockchain

“…The facets of disassembly operations include a variety of aspects, including scheduling [44], design for disassembly [45], disassembly line balancing [46][47][48], disassembly sequencing [43,49], and disassembly-to-order systems [43,50,51]. Lambert and Gupta [52] introduced a comprehensive study of various approaches utilized in disassembly.…”

Robotic disassembly re-planning using a two-pointer detection strategy and a super-fast bees algorithm

“…The preliminary disassembly sequence consists of both the order of component removals and their directions. 6. Each robotic operation is executed at a standard speed without extra processing.…”

“…Disassembly sequencing involves searching for an optimum order to dismantle a product partially or completely [5]. Disassembly line balancing is to assign multiple disassembly tasks to a group of workstations on a disassembly line to minimise the number of workstations, ensure similar idle times at different workstations or remove hazardous parts/required components at the earliest moment possible [6].…”

A Novel Multi-Efficiency Optimization Method for Disassembly Line Balancing Problem

“…To avoid this phenomenon and maximize both the value and disassembly efficiency of the disassembly line, VE is defined, which is not the maximization of the value obtained from the disassembled parts, but the maximization of the disassembly value in per unit time. Equations (5) and (6) are constrains of the objective functions. Equation 5represents that any task can be assigned to only one workstation.…”

“…Firstly, for each employee bee (parent1), randomly selects another individual parent2 (parent2 parent1). Secondly, randomly choose a swap position in parent1 and randomly choose a swap-able position in parent2 constrained by Equations (5) and (6). Then swap their positions, and four x pieces(x 1 ,x 2 ,x 3 ,x 4 ) and four d pieces (d 1 ,d 2 ,d 3 ,d 4 ) are generated.…”
