End of Life (EoL) products management through crude recycling methods and direct shredding causes severe threat to environment by different kinds of pollution. The environmental benefits such as reduced CO₂ emissions observed through recycling are mitigated by the direct release of toxic gases. De-manufacturing through systematic disassembly operations can reduce environmental damage but it requires more input cost to work within the threshold limit value (TLV). Complete disassembly sequence planning (CDSP) methods are not given importance in de-manufacturing objectives, which produce non-optimal solutions. The objective of present work is to produce an optimal solution to extract valuable materials from the EoL products while separating the toxic elements within TLV. A multi-layered method has been proposed that consists of five different layers, namely data input layer, application layer, modification layer, implementation layer and performance layer. It requires product bill of materials (BOM) and disassembly attributes such as liaison, geometric feasibility and stability as input from the user and generates an optimal solution by suggesting permissible operations to work within TLV. The proposed method has been applied on a case study and workability at producing practically feasible optimal solution has been confirmed. The effectiveness in working has been evaluated by comparing to the existing DSP methods. The proposed method can be used as a tool to achieve maximum profits through systematic disassembly operations within TLV by supplying essential information.

通过粗循环利用方法和直接切碎来管理寿命终止（EoL）产品管理会因各种污染而对环境造成严重威胁。减少CO ₂等环境效益通过回收释放的有毒气体可直接释放有毒气体，从而减少排放。通过系统的拆卸操作进行反制造可以减少对环境的破坏，但要在阈值极限（TLV）内工作需要投入更多的成本。完整的拆卸顺序计划（CDSP）方法在非制造目标中并不重要，因为这会产生非最佳的解决方案。当前工作的目的是提供一种最佳解决方案，以从EoL产品中提取有价值的材料，同时分离TLV中的有毒元素。已经提出了一种多层方法，该方法由五个不同的层组成，即数据输入层，应用程序层，修改层，实现层和性能层。它需要产品物料清单（BOM）和拆卸属性，例如联络人，用户输入的几何可行性和稳定性，并通过建议允许在TLV内工作的操作来产生最佳解决方案。所提出的方法已应用于案例研究，并在产生实际可行的最佳解决方案的可操作性方面得到了证实。通过与现有DSP方法进行比较，评估了工作的有效性。所提出的方法可以用作通过提供必要信息在TLV内进行系统拆卸操作来获得最大利润的工具。通过与现有DSP方法进行比较，评估了工作的有效性。所提出的方法可以用作通过提供必要信息在TLV内进行系统拆卸操作来获得最大利润的工具。通过与现有DSP方法进行比较，评估了工作的有效性。所提出的方法可以用作通过提供必要信息在TLV内进行系统拆卸操作来获得最大利润的工具。
