A Disassembly Optimization Problem
… in near perfect condition. However, product disassembly is a complex task requiring human labor as well as automated processes and, consequently, a huge amount of monetary investment. This research addresses a disassembly optimization problem, which aims at minimizing the costs associated …

Heuristics method for truck disassembly process
… parts can be used in remanufacturing processes. Disassembly is an important process that extract related valuable parts or subassemblies and materials from discarded products. The discarded products have high degree of uncertainty in the structure and the quality of the returned product. Some …

Case studies in disassembly process planning
… more efficiently is the availability of a disassembly process plan. In this thesis we represent set of intelligent disassembly rules that are able to automatically generate a disassembly plan. Few electronic equipments have been used to carry out experiments of disassembly process plans …

Staging disassembly : incubating post-industrial renewal
… the thesis will explore an incremental disassembly and phased reorganization of a site in Brooklyn at the material and urban scale. Through on-site implementation of manufacturers and automated tooling, this project will speculate on means of creating new value for salvaged materials. …

A biochemical investigation of actin disassembly mechanisms
… wound healing, motility and division of cells. Disassembly of actin filaments is extremely critical for the reorganization of cell shape. The cell possesses several factors that depolymerize actin filaments in an environment that has a high concentration of polymerizable monomer. However current …

Constraint-aware distributed robotic assembly and disassembly
… system capable of the efficient assembly and disassembly of complex three-dimensional structures. We introduce algorithms for equitable partitioning of work across robots and for the efficient ordering of assembly or disassembly tasks while taking physical constraints into consideration. We …

Programmable, isothermal disassembly of DNA-linked colloidal particles
… developing approaches to direct the assembly and disassembly of sub-micron sized particles will be paramount to further advances in materials science engineering. This project focuses on using programmable and reversible binding between oligonucleotide strands to assemble and then disassemble …

A strategic operations framework for disassembly in remanufacturing
Previous studies into the field of disassembly have widely focused on both product attributes. These attributes include the number of components, product structure, type of materials and other geometrical information. From a management perspective, disassembly that focuses on these attributes is …

Destructive disassembly of bolts and screws using impact
Disassembly, the process of separating parts or components at the end of their useful life is complex due to a variety of fastener shapes and variability in their damage during use. As a natural solution, mechanical impact has been suggested as a cost-effective method for destructive disassembly of …

SELF-ASSEMBLY, DEFORMATION, AND DISASSEMBLY OF SOFT MATERIALS
… such as self-assembly, deformation, and disassembly, dictating their functionality. These transitions can occur by design under given circumstances, allowing man and nature to meet targeted needs expeditiously, with soft matter literally underlying the phrase “well-oiled machine,” e.g. …

Urbanism of disassembly : strategies for Alang's shipbreaking industry
Waste is an integral part of our contemporary civilization based on consumption and material culture. From an empty soda can to the spent nuclear fuel rod, we define waste as the matter without immediate use: rotten, broken, unwanted. The notion of waste is also spatial-waste is simply matter in …

Distributed algorithms for self-disassembly in modular robots
We developed a modular robotic system that behaves as programmable matter. Specifically, we designed, implemented, and tested a collection of robots that, starting from an amorphous arrangement, can be assembled into arbitrary shapes and then commanded to self-disassemble in an organized manner. …

Innovative Design for Active Disassembly and Sustainable Product Recovery
… loop product lifecycle requires product ease of disassembly. Active disassembly, which uses external triggers that remotely disassemble active joints purposefully impeded in a product, shows great potential. The objectives of this dissertation are: first, to fulfill the need for comprehensive …

Shape formation by self-disassembly in programmable matter systems
Programmable matter systems are composed of small, intelligent modules able to form a variety of macroscale objects with specific material properties in response to external commands or stimuli. While many programmable matter systems have been proposed in fiction, (Barbapapa, Changelings from Star …

Force and effort analysis of unfastening actions in disassembly processes
… it is not very extensive. However, the need for disassembly is currently increasing. First, parts have to be taken apart for service and repair, and secondly, for the recycling process. Therefore, there is a need to consider unfastening during the design process in order to enable efficient …
