A method for dealing with multi-objective optimization problem of disassembly processes

Disassembly Line Scheduling with Genetic Algorithms

“…A cost function which combines both disassembly costs and revenues was proposed in [19,Duta,Filip,and Henrioud ].…”

“…We generated 24 matrices S that fulfill the constraints (5)- (7) by using the method presented in [19,Duta,Filip,and Henrioud]. We randomly chose three of them as shown bellow: Step…”

Applying Equal Piles Approach to Disassembly Line Balancing Problem

“…In the case of the disassembly lines we have to equalize the station loads by taking into account the appropriate disassembly task (destructive or not), or even in the situation of process failure. Another difference between the ALBP and DLBP is that in the last case the cycle time is not the ratio between the planning period and the demand of assembled products, but the ratio between the duration of the planning period and the maximum number of products that need to be disassembled to meet a certain demand of components (Duta, et al, 2003), (Gungor and Gupta, 1999).…”

“…When we speak of controlling a disassembly process we must take into consideration the use in real time of the Decision Support Systems (DSS). Usually, DSS in real time are used in "crisis" situations like: the stop of the production flow, the machines out of order, appearance of unpredictable situations, value changing of one or more production parameters (Filip, 2002). The DSS must be in permanent dialog with the control system.…”

“…Although the problem of DLBP seems similar to Assembly Line Balancing (ALBP) there are many important differences between assembly and disassembly processes (Duta, et al, 2003).…”
