This paper develops an integer mathematical programming model to design the cellular manufacturing systems under data envelopment analysis. Since workers have an important role in doing jobs on machines, assignment of workers to cells becomes a crucial factor for fully utilization of cellular manufacturing systems (CMS). The aim of the proposed is to minimize backorder costs and intercellul...

The purpose of the article is to introduce possibilities of manufacturing process by using special virtual tools from scientific field named augmented reality (AR) and their implementation on the real example from pruduct manufacturing area. After the introduction which sketch basic information about this mentioned scientific area of augmnted reality aided manufacturing, the first point quickly...

Virtual engineering technologies become an emerging field in industry and research. Nowadays, industrials are using Virtual and Augmented Reality in different phases of their manufacturing process (advanced manufacturing process visualization, assembly tasks, training, etc.). The purpose of this paper is to introduce the advantage of linking augmented reality application, to help employees on t...

As a result of the growing demand for highly customized and individual products, companies need to enable flexible and intelligent manufacturing. Cyber-physical production systems (CPPS) will act autonomously in the future in an interlinked production and enable such flexibility. However, German mid-sized plant manufacturers rarely use virtual technologies for design and validation in order to ...

When we first announced this hearing the Commerce Committee office got dozens of telephone calls from people asking what is “virtual reality” and why are you holding a hearing on it? Well, the answer is fairly simple. Virtual reality promises to revolutionize the way we use computers. At least that’s my opinion. It could improve the way we design new products, how we teach our children, and how...

This paper presents techniques of integrating haptic device into computer-aided design and manufacturing. The methodology is proposed as three steps: 1) develop the virtual sculpting system for aiding product design; 2) convert the product design into acceptable form for downstream manufacturing or rapid prototyping; 3) develop multi-axis polyhedral machining planning system with haptic input. ...

Manufacturing produces real wealth for any country and constitutes the back bone for the service sector. The objective of any organization is to earn profit. Usually the market fixes the selling price of the manufactured components. Unless there is focus on the manufacturing strategy of reducing manufacturing cost, it is very difficult to sustain in this ever competitive world. A suitable manuf...

This pilot project assessed the feasibility of Cellular Manufacturing at a ship maintenance facility. Using the PFAST software, several potential families of repair jobs, and the appropriate cluster of shops for each family, were identified. Based on these results, it was decided to implement a Focused Factory to complete any repair job done by the Dive Shop. The Dive Shop would be merged with ...
