Implementation of corporate production systems in the Brazilian auto industry: Managing knowledge through practice

International Journal of Automotive Technology and Management 2007年第2-3期7卷 153-167页

This paper discusses, from a Knowledge Management perspective, how leading automakers and autopart suppliers are struggling to reinforce competitiveness, by conceiving and deploying their proper Corporate production System (CPS) as a means to drive the revamping of manufacturing operations. Based on the investigation of exemplary cases, the paper examines the adoption of such prescriptive systems, focusing on the process of its company-wide implementation, and finds that this process becomes a strong learning mechanism. As the CPS elements are replicated and incorporated in the company practice, this approach leverages performance by nurturing the 'knowledge-as-action' perspective and ultimately provides a source of dynamic capability.

ENERGY POLICY 2007年第11期35卷 5784-5794页

作者： Sola, Antonio Vanderley Herrero Xavier, Antonio Augusto De Paula [a]Department of Industrial Automation Campus Ponta Grossa Federal University of Technology Paran¨￠ Brazil [UTFPR] Av. Monteiro Lobato Km 4 CEP: 84016-210 Brazil [b]Post Graduation Program in Production Engineering [UTFPR] Brazil

This paper presents a study accomplished in the State of Parana in Southern Brazil, aiming at verifying the correlation between organizational human factors (OHF) and the level of energy losses in organizations. The purpose is to subsidize the formularization of institutional policies in organizations to improve the energy efficiency in the productive sector. The research was carried out in ten industries of the following sectors: pulp and paper;food;wood and chemical products. The losses of electric energy were determined in motor systems with the aid of a mathematical model and the evaluation of 27 OHF identified in the literature review was made with the supervisors in the industries by means of a structurized questionnaire. Seven OHF had presented significant correlation with energy losses and six of them are inversely proportional to the losses, in accordance with linear regression analysis. The inversely proportional factors to the losses also with significant correlation are considered determinative OHF and constitute barriers for energy efficiency in organizations. These barriers are linked with the following organizational areas: management system;education of employees;strategical vision. The study recommends the implementation of the determinative OHF in organizations as a way to transpose the human barriers for energy efficiency. (C) 2007 Elsevier Ltd. All rights reserved.

The identification of a nonlinear system with chaotic behavior denoted Chua's oscillator by using fuzzy models intertwined with particle swarm optimization (PSO) method is presented. This hybrid approach is applied to experimental data generated by an inductorless Chua's circuit that consists of an electronic chaotic oscillator. Chua's circuit has been used as a test platform by various scientific and engineering communities related to the study of chaos due its great potencial in technological applications, for instance, telecommunications, cryptography and physics. Fuzzy set theory has been evolved as a powerful modeling tool that can cope with uncertainties and nonlinearities in modeling and identification procedures. The identification of a optimized fuzzy model Takagi-Sugeno (T-S) fuzzy model involves two primary tasks: parameter tuning and structure optimization. The premise part of production rules is optimized here by using the particle swarm optimization method. In turn, least mean squares technique is applied to the consequent part of a T-S fuzzy model. Results indicate PSO method and Least Mean Square technique succeeded in constructing a T-S fuzzy model when dealing with chaotic dynamics obtained through experimental data supplied by inductorless Chua's electronic circuit. © 2007 IEEE.

In the past it has been difficult to implement lean supply chain management in construction because one entity does not have control over an entire supply chain. This research investigates supply chain practices at GS engineering & Construction in Korea. The purpose of this case study is to explore the lean application on rebar supply chain management practice at GS. The paper discusses vertical integration in the supply system to reduce lead time and to improve a supplier's reliability. It also discusses production control system and task standardization for a contractor's planning reliability.

15th Annual Conference of the International Group for Lean Construction IGLC 15

In most cases, owners of companies or general contractors initiate Lean implementation on construction projects. The value in this case study is that it presents a subcontractor successfully implementing Lean construction on its projects. The case study investigated its motivation for making a Lean transformation, the course of its Lean transformation, and the lessons learned through its Lean journey. The study used interviews with twentyfive key personnel, twelve site visits, and an analysis of twelve documents on twelve projects. Further, it shows that while subcontractors have difficulty initiating Lean implementation beyond their own firms due to their lack of influence, it is possible for them to affect this kind of change.

Combining of chaotic differential evolution and quadratic programming for economic dispatch optimization with valve-point effect (vol 21, pg 989, 2006)

Evolutionary algorithms are heuristic methods that have yielded promising results for solving nonlinear, nondifferentiable, and multi-modal optimization problems in the power systems area. The differential evolution (DE) algorithm is an evolutionary algorithm that uses a rather greedy and less stochastic approach to problem solving than do classical evolutionary algorithms, such as genetic algorithms, evolutionary programming, and evolution strategies. DE also incorporates an efficient way of self-adapting mutation using small populations. The potentialities of DE are its simple structure, easy use, convergence property, quality of solution, and robustness. This paper proposes a new approach for solving economic load dispatch problems with valve-point effect. The proposed method combines the DE algorithm with the generator of chaos sequences and sequential quadratic programming (SQP) technique to optimize the performance of economic dispatch problems. The DE with chaos sequences is the global optimizer, and the SQP is used to fine-tune the DE run in a sequential manner. The combined methodology and its variants are validated for two test systems consisting of 13 and 40 thermal units whose incremental fuel cost function takes into account the valve-point loading effects. The proposed combined method outperforms other state-of-the-art algorithms in solving load dispatch problems with the valve-point effect. [ABSTRACT FROM AUTHOR]

The problem of failure occurrence in flexible manufacturing systems (FMS) tends to increase according to their complexity leading to time-consuming tasks as the localisation and repairing. The occurrence of failures during the exploitation stage can deeply modify the FMS performances or its availability. We want to investigate the maintenance integration into a control-monitoring framework, from the control system's early design stage to the maintenance policies execution, so as to improve production time and minimize unplanned costly breakdowns of FMS. This paper proposes a modular and hierarchic control-monitoring-maintenance architecture (CMM) for FMS based on Petri nets with objects (PNO). These efforts acts as a basis for the control architecture of a robot-driven flexible cell, connected to the Ethernet-TCP/IP. © 2006 IEEE.
