Ergonomic Indicators and Physical Workload Risks in Food Production and Possibilities for Risk Prevention
2021
The food industry is the most important and largest manufacturing industry in Latvia, producing almost a third of all manufacturing output. Employees in a food production enterprises are exposed to a variety of ergonomic risks: monotonous work movements that can be repeated up to 1000 times a day, overloads that exceeds 30 kg in lifting and moving operations, forced working postures, fast work pace. The aim of the study was to identify ergonomic indicators related to physical load for packers in one medium-sized company producing potato starch in Latvia. When summarizing the results of the survey on burden-lifting rates, it should be noted that, in a shift, 30% of packers lift the burden fr…
The Variation of Export Prices Across and within Firms
2016
This paper uses transaction-level trade data to analyse the differences in export prices across and within Spanish manufacturing firms in the year 2014. The transactional nature of the database uncovers sizable differences in the price that an exporter charges for the same product and destination. These differences are related to the number of goods covered within each product category, volume discounts and vertically differentiated varieties. Export prices are positively correlated with firms’ productivity, destination markets’ GDP per capita and distance to Spain. These latter results suggest that Spanish exporters compete in quality.
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.
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 …
Application and assessment of IDEF3‐process flow description capture method
1995
The IDEF techniques have been developed in projects sponsored by the US Air Force in order to describe, specify and model manufacturing systems in a structured graphical form. These techniques can be classified in two categories: the “modelling” and the “descriptive” varieties. Compares two IDEF methods (one of the modelling type and one of the descriptive type) in order to represent (model or describe) two different aspects of an industrial organization. The methods compared are IDEF0, function modelling method, and IDEF3, process flow description capture method. Concludes that when considering the sequencing of the activities in process, aiming at highlighting their eventual simultaneity,…
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…
Performance analysis of the closed loop supply chain
2012
Purpose The question of resource scarcity and emerging pressure of environmental legislations has brought a new challenge for the manufacturing industry. On the one hand, there is a huge population that demands a large quantity of commodities; on the other hand, these demands have to be met by minimum resources and pollution. Resource conservative manufacturing (ResCoM) is a proposed holistic concept to manage these challenges. The successful implementation of this concept requires cross functional collaboration among relevant fields, and among them, closed loop supply chain is an essential domain. The paper aims to highlight some misconceptions concerning the closed loop supply chain, to d…
Algorithm for workcells design
2021
The paper presents a methodology for the design of the manufacturing cells, covering all the necessary steps, from the analysis of the customers’ needs, to part families for group technologies, process engineering, control procedures, production rate, production planning (push or pull workflow), supply in the manufacturing cell, workcell configuration, work standardisation. The necessary tools through each stage are presented. Also, there are presented links to major company systems. For each design stage, deliverables are specified. this design approach is not linear. At each stage it is possible (and indicated) to go back and analyse the previously established parameters. The methodology …
Sensitivity analysis of efficiency and Malmquist productivity indices: An application to Spanish savings banks
2008
Hypothesis testing and statistical precision in the context of non-parametric efficiency and productivity measurement have been investigated since the early 1990s. Recent contributions focus on this matter through the use of resampling methods-i.e., bootstrapping techniques. However, empirical evidence is still practically non-existent. This gap is more noticeable in the case of banking efficiency studies, where the literature is immense. In this work, we explore productivity growth and productive efficiency for Spanish savings banks over the (initial) post-deregulation period 1992-1998 using Data Envelopment Analysis (DEA) and bootstrapping techniques. Results show that productivity growth…
Prevention of 7-ketocholesterol-induced side effects by natural compounds
2018
Cholesterol oxidation products, also named oxysterols, can be formed either by cholesterol auto-oxidation, enzymatically or both. Among these oxysterols, 7-ketocholesterol (7KC) is mainly formed during radical attacks that take place on the carbon 7 of cholesterol. As increased levels of 7KC have been found in the tissues, plasma and/or cerebrospinal fluid of patients with major diseases, especially age-related diseases (cardiovascular diseases, eye diseases, neurodegenerative diseases), some cancers, and chronic inflammatory diseases, it is suspected that 7KC, could contribute to their development. Since 7KC, provided by the diet or endogenously formed, is not or little efficiently metabol…
