With the increase of flexibility and production rates, the complexity of manufacturing systems reached a point where the operator in charge of the production activity control of the system is not able to forecast efficiently the impact of his decisions on the global performances. As a matter of fact, more and more Decision Support Systems (DSS) are developed, as much in literature or industrial...

We present three types of analog VLSI circuits that can be used in manufacturing inspection systems. The first set of circuits performs an adaptive threshold of an input image. The second circuit uses morphological operations with programmable structuring elements to detect oriented edges. Both of these circuits can be used as high speed preprocessors for visual inspection of manufacturing proc...

The increasing competitiveness in manufacturing industry is forcing manufacturers to seek effective processing schedules. The paper presents an optimization manufacture scheduling approach for dependent details processing with given processing sequences and times on multiple machines. By defining decision variables as start and end moments of details processing it is possible to use straightfor...

This paper focuses on data modeling for traceability of material/work flow in information layer of manufacturing control system. The model is able to trace all associated data throughout the product manufacturing from order to final product. Dynamic data processing of Quality and Purchase activities are considered in data modeling as well as Order and Operation base on lots particulars. The mod...

A mathematical model to describe the principle of layered manufacturing and layered fabrication error is presented in this paper. In this model, the layered manufacturing process is characterized by the model decomposition and material accumulation. A 3D design model is represented by a set of points with sequence functions to correlate the layered processing information. Iso-sequence planes ar...

With the help of a standard 2 × 2 trade model, we develop several hypotheses on the effects of cross-border sourcing on skill intensity in production. The focus is on cross-border sourcing of low-skill-intensive components of exports and import-competing products. We test the aforementioned hypotheses with panel data for manufacturing in the European Union (EU). We find that outward processing ...

The goal of this paper is to show the potential of fuzzy sets and neural networks, often referred to as soft computing, for aiding in all aspects of manufacturing of advanced materials like ceramics. In design and manufacturing of advanced materials it is desirable to find which of the many processing variables contribute most to the desired properties of the material. There is also interest in...

Task decomposition is on of the most important activities for manufacturing task planning in Manufacturing Grid. Many achievements in the methods to decompose manufacturing tasks have been obtained. But as for the decomposition granularity, the study and research are rare. Referring to the principle of “strong cohesion and weak coupling” in the software engineering field, the decomposition mode...
