The automotive industry has used in-line conveyor systems to move vehicles through the general assembly process since the early days of vehicle manufacturing in the 20th century. With products shifting to EVs (Electric Vehicle) and the emergence of AMRs (Autonomous Mobile Robot), there is an opportunity to transform the assembly process into a more...
The increasing demand for electric vehicles and the emergence of autonomous transport technologies within production like autonomous mobile robot or self-driving rolling chassis have raised the possibility of developing conveyor-less matrix assembly system. The conveyor-less matrix assembly system is characterized by high adaptability to demand cha...
In a high‐mix and low‐volume manufacturing facility, heterogeneous jobs introduce frequent reconfiguration of machines which increases the chance of unplanned machine breakdowns. As machines are often nonidentical and their performance degrades over time, it is critical to consider the heterogeneity and non‐stationarity of the machines during sched...

Using graph theory, we analyze the topological landscape of web service networks formed by real-world data set, either downloaded
from web service repositories or crawled by a search engine. We first propose a flexible framework to study syntactic web
service matchmaking in a unified manner. Under the framework, then, the data set is analyzed from...
When there are a large number of web services in use, it is non-trivial to quickly find web services satisfying the given request. Furthermore, when no single web service satisfies the given request fully, one needs to ldquocomposerdquo multiple web services to fulfill the goal. It is important to have a wise decision on underlying web-service comp...
