introduction: metalworking fluids (mwfs) are widely used in metal working operations for cooling down, lubricating and reducing the friction between tools and work pieces which result in controlling the heat produced. exposure to mwfs causes several adverse effects including respiratory problems, skin diseases, cancer and even infertility. this study examines workers’ exposure to mwf mist and t...

By now there still exists a major gap in the seamless information integration between product design and manufacturing processes. The reasons for this gap are manifold, however the incompatibility between the modeling philosophy used in the product design and for product manufacturing as well as the inconsistency in the data models and formats used in both areas are among the most obvious. Brid...

On-demand digital-print service offers mass customization and exemplifies personalized manufacturing services. We describe a real-time and online optimization technique based on genetic algorithms (GA) for print factory workflow optimization. We have simulated digital-print factory manufacturing activities as a heterogeneous, concurrent and integrated system. The simulation is based on a virtua...

The manufacturing industry is moving “digital” and the changes required are numerous and extensive. In general, there is a lack of understanding of how new technologies are beneficial to the manufacturing industry. This transformation, also known as the 4 industrial revolution or Industry 4.0, created the need of a research platform that could enable practitioners and academia collaboration on ...

In addition to Production, the interactions of diverse activi...

A case study approach was used to explore the adoption of an RFID-based garment manufacturing information system in a garment factory in China. The findings indicate that both the technology push factors and need pull factors influence the intention of the garment factory to adopt RFID technology. Technology push factors include relative advantage, compatibility, complexity, extendibility, and ...

The paper describes objectives and results of a research project conducted by Daimler–Benz AG. Intention of this project is decision support for a logistics division. In particular, the production flow control (PFC) in a factory has to be optimized by a decision support system. PFC is a sophisticated process influenced by complex factory structures and high dynamism of manufacturing processes. ...

Smart manufacturing technologies require a cyber-physical infrastructure to collect and analyze data and information across the manufacturing enterprise. This paper describes a concept for a product lifecycle test bed built on a cyber-physical infrastructure that enables smart manufacturing research and development. The test bed consists of a Computer-Aided Technologies (CAx) Lab and a Manufact...

Abstract— In order to determine factory capacity or necessary time to reach a desired quota, the manager of a multi-product batch manufacturing system must know the best method of scheduling for the factory. To determine the optimal scheduling, 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 det...
