As the manufacturing tasks become more individualized and more flexible, the machines in smart factory are required to do variable tasks collaboratively without reprogramming. This paper for the first time discusses the similarity between smart manufacturing systems and the ubiquitous robotic systems and makes an effort on deploying ubiquitous robotic technology to the smart factory. Specifical...

Abstract— In order to determine necessary time to reach a desired quota, the manager of a flexible batch manufacturing system must know the best method of scheduling the factory. To determine a sub-optimal schedule, we first create a model of the factory. This model is used to simulate the factory. Using this simulation and an integer programming formulation, we determine a scheduling algorithm...

This paper describes an integrated system for the design and production of sheet metal parts. We have identified some important features for the sheet metal bending process. These features are automatically generated as the design progresses. After the designs are complete, our automatic process planning system uses the features and generates new ones to aid the production of plans with near-mi...

Structuring the information and knowledge needed to implement a factory, as well as doing its control and management by computer systems, is the purpose of the meta-model and solutions here presented. This meta-model includes: an object-oriented model to structure the needed information and knowledge; a model for manufacturing systems; a prototype that integrates the two previously referred mod...

Historically, manufacturing engineering education has focused on teaching mathematical models using simplifying assumptions that can mask the realities of complex manufacturing systems. Recent pedagogical approaches to manufacturing education have focused on developing a more holistic view of the manufacturing enterprise. In this paper, we describe the contents and development methodology of a ...

The Automated Manufacturing Research Facility (AMRF) is a unique engineering laboratory at the National Institute of Standards and Technology (NIST†) Center for Manufacturing Engineering. The facility provides a basic array of discrete metal parts manufacturing equipment and control systems – a testbed – that researchers from NIST, industrial firms, universities and other government agencies ca...

run reliably for long periods of time under intense use. They have not traditionally been known for their flexibility and changeability. When something does go wrong, the entire system may need to be shut down, with every minute of down time representing lost production and possibly damaged product. Further, making changes in a factory line can require extensive redesign, retooling, and reprogr...

Agent based distributed manufacturing control and scheduling systems are subsets of new manufacturing systems. Multi agent systems (MAS) not only drive design and engineering control solutions but also influence flexibility, agility, and re-configurability, which makes MASs a better centralized systems than its traditional counterparts. However, implementation of all MASs in the real factories ...

background: occupational exposure to cotton dust, fibers, metal fumes and different chemicals used in the apparel manufacturing industries cause a wide range of physical and psychological health problems in the garment workers that may also affect their immune function. objective: to assess the immune system function in garment workers. methods: a total of 45 workers of a garment factory, and 4...
