The Open Assembly Design Environment (OpenADE) project is an initiative at the National Institute of Standards and Technology (NIST) to provide an integrated and augmented CAD environment for assembly design. The goals of the project are: (1) to identify representations and issues for the next generation of assembly-related standards and (2) assist designers with assembly considerations through...

In this paper, a Job shop scheduling problem with a parallel assembly stage and Lot Streaming (LS) is considered for the first time in both machining and assembly stages. Lot Streaming technique is a process of splitting jobs into smaller sub-jobs such that successive operations can be overlapped. Hence, to solve job shop scheduling problem with a parallel assembly stage and lot streaming, deci...

The strategic pricing decisions of assembly products in assembly products supply chain are studied in this paper. Firstly, a two-stage assembly products supply chain model is developed. By building Nash game model, the Nash equilibrium solution of pricing strategy of supplier and assemblers is obtained. Next, a union decision model is built to analyze the optimal combination pricing strategy of...

Stereolithography (SL) technology is the mostly widely used Rapid Prototyping (RP) process in which complex structures are fabricated in a layer-bylayer fashion. Currently Microstereolithography (MSL) is undergoing fast development. In this paper, the development of MSL and its application in micromanufacturing are reviewed. One promising direction for the development of MSL is the assembly-fre...

The topic of guided self-assembly of Ge and InAs quantum dots on Si (001) substrates via epitaxy is discussed. A buried misfit dislocation network can be used to guide the assembly process through the associated strain field. Patterned substrates can also be used to guide the assembly process. This paper discusses the recent experimental and theoretical studies of the guided assembly process wi...

Amyloid-β (Aβ) self-assembly into cross-β amyloidfibrils is implicated in a causative role in Alzheimer’s disease pathology.Uncertainties persist regarding the mechanisms of amyloid self assembly and the role of metastable prefibrillar aggregates. Aβ fibrilsfeature a sheet-turn-sheet motif in the constituent β-strands; as such, turn nucleation has been proposed as a rate-limiting step in the se...

Considering the present business competitive scenario, the automotive industry is under pressure to achieve higher productivity. A high level of performance and quality standard could be achieved through improving the Overall Equipment Effectiveness (OEE) of the equipment in an automotive industry. Thus, the aim of this study is to investigate the performance measurement through OEE theory in a...

Visual feedback has traditionally been used in the assembly process to a very limited extent. With the advent of effective visual servoing techniques, visual feedback can become an integral part of the assembly process by complementing the use of force feedback to accomplish precision assemblies in imprecisely calibrated robotic assembly workcells. In this paper we present some of the issues pe...

We introduce a new notion in self-assembly, that of transforming the dynamics of assembly. This notion allows us to have transformation of the plane computed within the assembly process. Then we apply this notion to zooming, which gives us an impossibility result allowing us to pinpoint the notion of locality in the assembly process, and then a construction which allows us to make assembly some...
