The product recovery operations are fully based on disassembly line balancing. The disassembly line is a best chaise of automated disassembly or returned product. It is very difficult to find the optimal balance of a disassembly line because of its N-P hard nature. In this paper a new U-shaped heuristic is proposed to assign the parts to the disassembly work stations under precedence constraint...

Promoter chromatin disassembly is a widely used mechanism to regulate eukaryotic transcriptional induction. Delaying histone H3/H4 removal from the yeast PHO5 promoter also leads to delayed removal of histones H2A/H2B, suggesting a constant equilibrium of assembly and disassembly of H2A/H2B, whereas H3/H4 disassembly is the highly regulated step. Toward understanding how H3/H4 disassembly is re...

Disassembly Sequence Planning (DSP) is a challenging NP-hard combinatorial optimization problem. As a new and promising population-based evolutional algorithm, the Teaching–Learning-Based Optimization (TLBO) algorithm has been successfully applied to various research problems. However, TLBO is not capable or effective in DSP optimization problems with discrete solution spaces and complex disass...

After attachment to receptors, reovirus virions are internalized by endocytosis and exposed to acid-dependent proteases that catalyze viral disassembly. Previous studies using the cysteine protease inhibitor E64 and a mutant cell line that does not support reovirus disassembly suggest a requirement for specific endocytic proteases in reovirus entry. This study identifies the endocytic proteases...

The first crucial step of product recovery is disassembly. Some product disassembly is almost always needed in remanufacturing, recycling, and disposal. Since disassembly tends to be expensive, disassembly sequence planning becomes important in minimizing resources (time and money) invested in disassembly and maximizing the level of automation. A disassembly sequence plan (DSP) is a sequence of...

The establishment of disassembly plants and the creation of product designs which specifically facilitate disassembly are enabling manufacturers to carry out item segregation. Item segregation is defined as the separation from an assembly of a part or a group of parts by following a reverse assembly process. Once segregated, the items can be reused, recycled or discarded. However, there are ope...

Abstract: The best choice for large scale disassembly processing is a disassembly line. In this paper, we consider a disassembly line balancing problem (DLBP) with multiple objectives that requires the assignment of disassembly tasks to a set of ordered disassembly workstations while satisfying the disassembly precedence constraints and optimizing the effectiveness of several measures. The four...

An important aspect in recycling and reuse for environmentally conscious manufacturing is disassembly. Although disassembly systems contain the same basic elements as assembly systems, the disassembly problem differs significantly from the assembly problem due to the fact that the incoming disassembly product is not controlled. In addition, complete dismantling of products is not necessarily re...
