In this paper we suggest an evolutionary computational approach by applying a combination of a genetic algorithm and a tabu search to obtain a good solution for relatively large unidirectional automated guided vehicle flowpath design problems. Unidirectional flowpaths are used to lessen the traffic control loads for large fleets of vehicles and to increase(More)
As the cyber-attack trends are shifted from the volumetric attacks to the multi-layered attacks, it is more difficult for the IT administrators to find those attack attempts within their system and networks. However, vulnerability assessment is not easy due to the complex connections between multi-layered applications, servers, and networks. There are many(More)
Functionally graded properties are characterized by the variation in composition and structure gradually over volume, resulting in corresponding changes in the properties of the material. Direct laser melting (DLM) process is a kind of prototyping process whereby a 3-D part is built layer-wise by melting the metal powder with laser scanning. DLM can(More)
