Today’s product demand and mix changes requiring reconfiguration of cells in each period of a multi-period planning horizon, This paper proposes a mixed-integer non-linear programming model for reconfigurable CMS design to meet changes in product mix & demand in each period of a multi-period planning horizon. The proposed model, to the best of author’s knowledge, is the most comprehensive model...

Product design is an evolving process which is characterized with creativity and uncertainty. The task management in this process is different from traditional ones because it involves more specific factors such as user specifications, product design specifications, reengineering, design process, and design data. In this article, we aim to analyze product design process with the viewpoint of pr...

Stress grading (SG) layer in cable terminations limits the critical electric field and properties of SG materials are important issues which have to be considered during manufacturing and selecting procedure. In this paper, two different types of (SG) materials are analyzed by both theory and test. According to the applied theory, important parameters as: electrical resistivity, breakdown volta...

Executive Summary This deliverable D4.1b describes work done in the area of machine translation development and deployment (work package 4) during the period of the second milestone of the project (from month 7 to month 24). As part of this second development cycle, we have built a new generic MT system by building upon the system we prepared for milestone 1; we have then broadened our scope by...

aggregate stability is an important soil property because it dictates how strongly a soil can resist water erosion. the objectives in this study were: (1) to compare the stability of six soil aggregate size fractions, primarily to determine if aggregate stability varies with aggregate size, and (2) to determine with which aggregate size fraction the stability of most soils would be different fr...

The air quality of the living area influences human health to a certain extent. Therefore, it is particularly important detect indoor air. However, traditional detection methods mainly depend on chemical analysis, which has long been criticized for its high time cost. In this research, rapid method environment using laser-induced breakdown spectroscopy (LIBS) and machine learning was proposed. ...

Most of the research literature concerning scheduling concentrates on the static problems, i.e problems where all input data is known and does not change over time. However, the real world scheduling problems are very seldom static. Events like machine breakdown or bottleneck in some situation impossible to predict. Dynamic scheduling is a research field, which take into consideration uncertain...

The partial discharge activity during propagation of electrical treeing in epoxy resin is described. The electrical trees grew in needle-plane samples without and with an internal barrier up to the final breakdown. The simultaneous taken tree growth and discharge activity show a correlation between the propagation state of the tree and the thereby measured PD. Especially the changes in the tree...

This paper contains a detailed description of a thirteen machine COMAU FMS for a company in Torino, Italy. The monthly and daily problems that need to be addressed and the approaches that are suggested to operate this system efficiently are detailed. The trickier probicms and constraints are those of tool management, especially tool loading. Detailed tooling data and their analysis are also pre...
