Recently, production demand in manufacturing industries has changed drastically from demand for high-mix, low-volume production to that for high-mix, variable-volume production. At Fujitsu, we are promoting innovative engineering through the effective use of existing equipment without the need for additional investments and by implementing the Toyota Production System. Two major themes of manuf...

This paper describes a novel 3D simulation modelling system for supporting our distributed machine design and control paradigm with respect to simulating and emulating machine behaviour on the Internet. The system has been designed and implemented using Java2D and Java3D. An easy assembly concept of drag-and-drop assembly has been realised and implemented by the introduction of new connection f...

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...

Rapid prototyping (RP) methods are used for production easily and quickly of a scale model of a physical part or assembly. Gas metal arc welding (GMAW) is a widespread process used for rapid prototyping of metallic parts. In this process, in order to obtain a desired welding geometry, it is very important to predict the weld bead geometry based on the input process parameters, which are voltage...

Realistic evolutionary fitness landscapes are notoriously difficult to construct. A recent cutting-edge model of virus assembly consists a dodecahedral capsid with $12$ corresponding packaging signals in three affinity bands. This whole genome/phenotype space consisting $3^{12}$ genomes has been explored via computationally expensive stochastic models, giving landscape terms the efficiency. Usi...

The Mechanical Engineering Laboratory developed a prototype desktop machining microfactory. The microfactory, which will enable considerable savings in terms of energy, space, and resources, is a downsized production system whose size is very small with respect to the dimensions of the products. The desktop microfactory consists of machine tools such as a microlathe, a milling machine, a press ...
