Aiming to address this Issue, It is proposed a knowledge-based approach is proposed to Integrate quality function deployment, ...

This paper studies the specific Product Lifecycle Management (PLM) capabilities needed for the transformation of Engineered to Order (ETO) manufacturing towards Configure to Order business strategy. The material for the research comes from a project conducted with public private partnership. The four industrial companies that we studied engineer and/or manufacture highly customized products in ...

To achieve different assembly operations on the aircraft structure, the aeronautic OEM needs to create and manage various fixture tools. To cope with these needs, the OEM begun to adopt the supplier integration into the tooling development process. This paper presents a conceptual PLM-based approach to support new business partnership of different suppliers. The new business partnership aims to...

Product Lifecycle Management (PLM) systems are widely used in the manufacturing industry. A core feature of such systems is providing support for versioning of product data. As workflow functionality is increasingly used in PLM systems the possibility emerges that versioning policies as encapsulated in process models are inconsistent with respect to their actual lifecycles. In this paper we def...

This paper deals with the complex issue of interoperability methods and technologies especially in PLM field. Windchill is one of the most popular PLM software proposing robust solutions to support communication with external information systems. The purpose of this paper is to prospect the interoperability mechanisms offered by PTC editor as a solution to interoperability issue. A new interope...

The contribution of this paper is to propose a systematic approach to the observer design for linear time-varying systems. It is based on the exact rewriting of the original time-varying system into a polytopic linear model (PLM). This transformation uses the sector nonlinearity approach based on the convex polytopic transformation. Then a joint state and parameter observer can be designed for ...

A wavelet approach is presented for estimating a partially linear model (PLM). We find an estimator of the PLM by minimizing the square of the l2 norm of the residual vector with penalizing the l1 norm of the wavelet coefficients of the nonparametric component. This approach, an extension of the wavelet approach for nonparametric regression problems, avoids the restrictive smoothness requiremen...

The Cox proportional hazards model is ubiquitous in time-to-event studies of political processes. Plausible deviations from correct specification and operationalization caused by problems such as measurement error or omitted variables can produce substantial bias when the Cox model is estimated by conventional partial likelihood maximization (PLM). One alternative is an iteratively reweighted r...

CTR prediction in real-world business is a difficult machine learning problem with large scale nonlinear sparse data. In this paper, we introduce an industrial strength solution with model named Large Scale Piece-wise Linear Model (LS-PLM). We formulate the learning problem with L1 and L2,1 regularizers, leading to a non-convex and non-smooth optimization problem. Then, we propose a novel algor...

Today, within the global Product Lifecycle Management (PLM) approach, success of design, industrialization and production activities depends on the ability to coordinate and improve the interaction among information systems that handle such activities. Enterprises deploy mainly the PLM system, the Enterprise Resource Planning system (ERP) and the Manufacturing Execution System (MES) in order to...
