Current Issues on Production Economics
2015
This Special Issue includes a selection of papers which originally were presented and discussed at the Eighteenth International Working Seminar on Production Economics, Innsbruck, February 24–28, 2014 and subsequently extended and improved. Production Economics was established in the 1970s as an academic discipline focusing on scientific topics treating the interface between engineering, management, and economics with a special emphasis on the financial consequences of decisions in the production domain. The subject is interdisciplinary in nature and it therefore contains a wide range of subjects. The Working Seminar included sessions such as supply chain management, innovation management, ge…
Economic lot scheduling on multiple production lines with resource constraints
2003
Abstract This paper deals with the multiple production line economic lot scheduling problem, where some items cannot be produced concurrently since they compete for some discrete resources. In particular, cyclic schedules are sought for a problem where identical production lines are present, lost sales are allowed, and minimization of the long-range production, setup, inventory, and shortage penalty costs are required. A heuristic procedure for this problem is introduced, a numerical example is worked out and some computational experiments are presented.
Study of the imaging conditions and processing for the aspect control of specular surfaces
2001
A vision system capable of imaging and detecting defects on reflective nonplanar surfaces in the production line at a high cadence is presented in this paper. Defects are typically dust located under the metallic layer of packaging products used in cosmetic industries. To realize this processing, structured lighting which reveals the defects in the image is proposed. Defects appear clearly in the images like a set of brilliant pixels in dark zones. The signature of the defect is then obtained. The size of this signature does not depend linearly on the size of the defect. It is a function of the observation angle. In order to realize a precise and robust process, the necessity of acquiring s…
Using QSPS in Developing and Realization of a Production Line in Automotive Industry
2010
<p>Using the QSPS (Quality System for the production software) for industrial projects and not only therefore, has led to accurate running of the production line from beginning of the SOP (Start of Production). This paper presents the application way of the QSPS at one of the strongest European automotive company. By using of this system several significant costs savings and quality improvement can be observed.<br /> The content of this paper will show step by step how to use QSPS for the integration of a production line in the traceability system from a big company in automotive industry.<br /> The production line involved contains 56 production equipments, which have to …
Hyperspectral image classification using CNN: Application to industrial food packaging
2021
Abstract During food tray packaging, some contamination may exist due to the presence of undesired objects. It is essential to detect anomalies during the packaging process in order to discard the faulty tray and avoid human consumption. This study demonstrates the on-line classification feasibility when using hyperspectral imaging systems for real-time food packaging control by using Convolutional Neural Networks (CNN) as a classifier in heat-sealed food trays. A hyperspectral camera is used to capture individual food tray information and fed to a CNN classifier to detect faulty food trays with object contamination. The proposed system is able to detect up to eleven different contamination…
Managing adoption by cultural development: Exploring the plant level effect of a ‘Company Specific Production System’ (XPS) in a Norwegian multinatio…
2020
Purpose: ‘Company Specific Production Systems’ (XPS) aim to adopt ‘best practice’ across plants within a company. A pertinent issue in the literature involves the constraints in the possibilities of realising such an adoption. This paper addresses to what extent and how a Norwegian multinational succeeded in adopting the XPS in its local plants. Design/methodology/approach: A Brazilian, Chinese and Norwegian plant of a Norwegian electro-chemical company were studied from 2017 to 2019. Our data consist of the results of the plant’s assessment performance program, combined with interviews and observations at different organizational levels. Findings: The MNC had largely managed to adopt the X…
Quantification de l’ablation d’un bassin versant marno-calcaire alpin durant le Petit Age Glaciaire par l’étude d’un système lacustre (cas du lac du «…
2002
Measurements of present-day erosion may give heterogeneous results according to the methods used. This article proposes an approach to erosion during the Little Ice Age by the quantitative analysis of detritical materials trapped in a dammed lake. This infill is recognized through two drillings, and these specific observations are supplemented by a seismic reflexion survey which provided a reliable estimate of the geometry of the lake infill. The sedimentary production is calculated from three pieces of data: (1) the surface of the drainage area, (2) duration of the lake system activity and (3) the volume of trapped sediments. From the three determined variables, we propose a detritical product…
Uso secuencial de herramientas de control de calidad en procesos productivos: una aplicación en el sector agroalimentario = Sequential use of quality…
2014
<p>Las diferentes herramientas del Control Estadístico de Calidad proporcionan mejores resultados si su uso se lleva a cabo de manera secuencial, facilitando la detección de los puntos débiles del proceso productivo. Así, en el presente estudio se expone un método de trabajo en el que se utilizan, atendiendo a la necesidad en cada punto de la cadena de producción, algunas de dichas herramientas. Concretamente se propone el uso del diagrama de flujo, gráfico de Pareto, hojas de comprobación, gráficos de control (en este caso gráfico p y gráfico de media-recorrido), así como el análisis de la varianza (ANOVA). El procedimiento se aplica a una empresa del sector agroalimentario, interesa…
Contributions Regarding the Reduction of Production Costs for Brewing by Recovering and Reusing the Carbon Dioxide
2014
Abstract Nowadays in every field the main aim is to produce corresponding quality products at competitive prices for buyers. In addition to the multiple possibilities to reduce the brewing production cost, one of the most significant ways is to reduce the production cost by recovering the carbon dioxide (CO2) resulting from the fermentation of beer, taking into account the fact that the CO2 thus resulting is completely natural. This scientific paper presents a certain strategy based on costs, strategy which relies on the experience of the authors, on the economic impact of CO2 recovery resulting from the fermentation of beer and which reflects itself in the production cost and implicitly in…
Search for the Associated Production of the Standard-Model Higgs Boson in the All-Hadronic Channel
2009
We report on a search for the standard-model Higgs boson in pp collisions at s=1.96 TeV using an integrated luminosity of 2.0 fb(-1). We look for production of the Higgs boson decaying to a pair of bottom quarks in association with a vector boson V (W or Z) decaying to quarks, resulting in a four-jet final state. Two of the jets are required to have secondary vertices consistent with B-hadron decays. We set the first 95% confidence level upper limit on the VH production cross section with V(-> qq/qq('))H(-> bb) decay for Higgs boson masses of 100-150 GeV/c(2) using data from run II at the Fermilab Tevatron. For m(H)=120 GeV/c(2), we exclude cross sections larger than 38 times the standard-m…
