A Predictive Approach for Disassembly Line Balancing Problems

Abstract

In selective serial disassembly sequence planning, when the target node (component) is reached, the selective disassembly task is completed and the refurbished component is repaired, reused or remanufactured. Since the efficient utilization of existing resources is necessary, it is crucial to predict disassembly operation times and the condition of joints for recycling, reusing or remanufacturing. The method of estimating the disassembly times of a joint if it is intended for remanufacturing, recycling and reuse is an important and urgent requirement for research development and results. The aim of the paper is to investigate the disassembly system with predicted operation times and the quality of product connections (joints) in order to balance the line smoothness index, to minimize a line time factor, line efficiency and profit and minimize an ex post error. Disassembly times for remanufacturing, recycling and reuse are estimated separately based on the historical data of disassembly times and the quality of joints. The presented estimation method of disassembly operation times increases the reliability and efficiency of elaborated balances of tasks in lines. Underestimated disassembly operation times can be compensated for during the idle points in the successive cycles, provided that the transport operations are performed manually and that travel time determines the cycle time.

A Novel Simulated Annealing-Based Hyper-Heuristic Algorithm for Stochastic Parallel Disassembly Line Balancing in Smart Remanufacturing

“…In summary, the exact method may obtain the optimal solution, but it has limitations and is not suitable for solving the large-scale and multi-objective optimisation of DLBP. The exact method consumes high computing resources and time dealing with large-scale optimisation of DLBP [ 31 ]. According to the characteristic of heuristic algorithms, the proposed heuristic algorithms cannot obtain the optimal solution of NP problems and easily obtain the local optimal solutions [ 32 ].…”

Transient Behavior of a Queueing Model with Hyper-Exponentially Distributed Processing Times and Finite Buffer Capacity

“…The balancing result is the determination of the smallest number of stations in a given cycle time or the determination of the lowest cycle value for a given number of disassembly stations. The problem of estimating the times of disassembly operations was considered in [6]. In order to establish a sequential relationship between operations, it is necessary to predict the frequency of product arrival and its quality.…”

Modeling and solving the parallel mixed-flow remanufacturing disassembly line balancing problem for multi-variety products

“…Disassembly is the key step in obtaining the remanufacturing cores. The remanufacturing disassembly line balancing problem (RDLBP) focuses on obtaining an optimal disassembly line configuration scheme with reasonable task allocations, balanced workstation operations, a high disassembly efficiency, and a low cost, thereby reducing the remanufacturing costs 1 , 2 .…”
