Agent-based approaches to manufacturing scheduling and control are attractive because they offer increased robustness against the unpredictability of factory operations. Previously, we introduced a new approach to coordinating factory routing and scheduling based on a computational model of wasp behavior. The natural multi-agent system of the wasp colony is highly effective in selforganizing th...

This contribution describes the methods used in a factory floor optimization process. The manufacturing process involves approximately 140 machines and is concentrated around a group of multipurpose CNC machines. We have analysed the current state of the manufacturing system by constructing a discrete event simulation (DES) model. The factory manufactures approximately 30,000 different products...

The costs of additive manufactured parts often seem too high in comparison to those of traditionally manufactured parts, as the information about major cost drivers, especially for additive manufactured metal parts, is weak. Therefore, a lifecycle analysis of additive manufactured parts is needed to understand and rate the cost drivers that act as the largest contributors to unit costs, and to ...

The integrated circuit (IC) manufacturing process is capital intensive and complex. production of unit product (or die, as it commonly referred to) takes several weeks. Semiconductor factories (fabs) continuously attempt to improve their productivity, measured in output cycle time mean flow time). conflicting objective producing maximum units at minimal the highest quality, by die yield, discus...

In today’s globalized markets, the continuous pressure to perform at high levels is well perceivable in the companies’ every day business. The concepts of both a changeable and a virtual production, also known as the digital factory, claim to be of great importance when preparing the manufacturing and assembly systems for future challenges. In this paper, the characteristics of both concepts ar...

Among the advantages of visual dataflow programming is that it can give the user a sense of location for the data in a computation. This can help novices build a mental picture of a program and its execution. This paper presents an experimental programming system called the Data Factory that uses a manufacturing metaphor to give data an even stronger sense of place. A key affordance for learner...

background solvents such as benzene and toluene are commonly used in tire manufacturing, and significant occupational exposure to these chemicals adversely affects the health of workers. in biological monitoring, a complementary method for personal monitoring, the internal absorbed dose is measured and individual, environmental, and exposure differences are taken into consideration. conclusions...

Inspired by round-the-clock manufacturing, the 24-Hour Knowledge Factory endeavors to transform the production of software and other intangibles into a process of continuous development. While the concept of offshore software development is well established, few enterprises are currently able to develop the same code artifacts around the clock. We discuss the benefits of applying the 24-Hour Kn...

To meet competitive market for the electronics consumer products, the integrated circuit is process at the semiconductor fabrication factory which is the most complex and challenging areas in manufacturing. This is due to semiconductor manufacturers will require to process 300 to 1000 steps depends on products, 60,000 WIP and 400 pieces equipment for typical 200mm wafer size technology. Due to ...
