Adjusting the Factory Planning Process when Using Immature Technologies

Due to shorter product-life-cycles, innovations in production engineering have to keep pace with today's technologies. As a result, factory planning is more and more challenged by technologies being immature for series production. Usually, these immature technologies place special demands on production layout and quality management, for example. These demands have to be considered in the factory planning process. Moreover, technologies are part of the production process that is created by a series of technologies. Hence, a planning process has to ensure that the positive aspects of a new technology are not negated by arrangements to protect the technology chain against failure due to immature technologies.With Selective Laser Melting (SLM) used as example for an additive manufacturing technology, this paper presents a method of planning a production system by taking the technology maturity into account. Possible requirements of an immature technology interacting with the process chain will be addressed as well as adjustments to be made to the factory planning process.

Modelling the Impact of Environmental and Organizational Determinants on Green Supply Chain Innovation and Performance

ABSTRACTBoth customers and suppliers are becoming increasingly concerned about environmental issues in modern food chains. A firm’s decision to implement green supply chain management is based on the social objectives of the firm and its management, its desire to pursue corporate social responsibility, its relationships with channel partners, and environmental determinants such as government legislation. The speed at which green supply chain management is implemented within an organization depends on its agility and its ability to facilitate innovation. Innovation may take the form of new product development or new process development, including the introduction of environmental management systems and total quality management in both production and purchasing. This article presents a conceptual model to explain how the various theoretical constructs are related and how innovation effects green supply chain management and performance.

Requirements for microbiological quality management of the agricultural products

Purpose – The purpose of this paper is to portray a general situation on the microbiological spoilage aspects of agriculture and focus on the necessary management schemes of microbiological contamination aiming to deliver information on the public health safety. Design/methodology/approach – A substantial number of local studies on nutritional policies have been performed earlier; however, the microbiological quality control of the agricultural products is still scarce. This review analyzes the microbiological aspects of local agricultural products together with the study findings relevant to food safety as published both globally and locally. Findings – Ongoing awareness on the microbiological quality in accordance to the recommended microbiological limit of different fresh produces would deliver a practical outcome in the safe crop management. Information on microorganisms contaminating agricultural products is expected to ensure public health safety especially within the developing countries along with Bangladesh. Originality/value – The improvements in agriculture status in Bangladesh, particularly in microbiological quality perspective, have been relatively slow, principally due to lack of knowledge on the health risks within the mass population caused by microorganisms harbored through the agricultural products. The novelty of the current review, thus, underlies the necessity of microbiological quality management of the agricultural products, projection on the specific microorganisms contaminating the agricultural products and possible disease outbreaks caused by the consumption of these contaminated products.

Quality management of repair production for disassembly of pressure coupling

The problems of quality management of disassembly of pressure coupling for effective functioning of repair production are considered because the effective use of machinery and equipment is the high level of maintenance and repair, which affects product quality and production costs. A condition for quality disassembly is to preserve parts of the repaired product. Particularly complex disassembly of pressure coupling is complex if they large or design does not allow using simple mechanical pullers as well as compounds which, as a result of heavy operation, is one-piece steel. Quality and productivity disassembly of such compounds occurs only using induction heating. However, normative-technical provision of such technologies is virtually absent, which makes their use is not effective in energy costs. Therefore, the aim of the work was to determine and justify the principle of laying the foundations of normative and technical provisions of quality, energy-efficient and productive technology of repair production for example, disassembling connections with interference when using induction heating. The structural-parametric principle for creating a normative-technical provision, system of construction classifications of disassembled pressure coupling with heating parts in their inbox, unified operations based on the account settings, limiting quality of products and a mathematical model of the process of repair of thermal technologies on the example of disassembling connections with interference which can be used for quality control in the production of repair schemes for any pressure coupling.

Pareto Analysis of Critical Success Factors for Total Quality Management Targeting the Service Industry

Recent advances in omic technologies for meat quality management

The knowledge of the molecular organization of living organisms evolved considerably during the last years. The methodologies associated also progressed with the development of the high-throughput sequencing (SNP array, RNAseq, etc.) and of genomic tools allowing the simultaneous analysis of hundreds or thousands of genes, proteins or metabolites. In farm animals, some proteins, mRNAs or metabolites whose abundance has been associated with meat quality traits have been detected in pig, cattle, chicken. They constitute biomarkers for the assessment and prediction of qualities of interest in each species, with potential biomarkers across species. The ongoing development of rapid methods will allow their use for decision-making and management tools in slaughterhouses, to better allocate carcasses or cuts to the appropriate markets. Besides, their application on living animals will help to improve genetic selection and to adapt a breeding system to fulfill expected quality level. The ultimate goal is to propose effective molecular tools for the management of product quality in meat production chains.

軟X線透過率を用いた複合材料のボイド率定量化手法に関する検討

Carbon fiber reinforced thermoplastics (CFRTP) have great potential about high-cycle molding in one minute. However, the relationship between cost reduction and well-impregnated composite materials for automotive parts is trade-off because thermoplastic resins have high viscosity and difficulty for impregnation into reinforcement fibers. So an effective quantification on impregnation of CFRTP is required for mass production of automotive parts. Non-destructive quantification of void fraction of CFRTP with soft X-ray transmittance were investigated. We measured X-ray transmittance of CF/PP plate with 3 different void content. As a result, the attenuation coefficient of X-ray had highly linear correlation with the density, which can be used to calculate void fraction of composite. In conclusion, non-destructive measurement by soft X-ray can be applied for the quality management of mass production of automotive parts because the distribution of void content in parts can be measured.

Effect of Selected Parameters on Process Efficiency and Energy Consumption During the Extrusion-cooking of Corn-rice Instant Grits

Abstract More and more people begin to pay attention to how foodstuffs are produced. Due to the changing lifestyle, consumers seek products that do not require long preparation. The extrusion-cooking process responds to this type of applications with an easy management of processing promising product stability and quality. Extrusion-cooking involves the extruding of granular material under high pressure and high temperature. Such a method of treatment of raw materials makes extrudates produced from natural ingredients, i.e. corn or rice, suitable for direct consumption and guarantees their prolonged shelf-life. In our study, mixtures for instant grits were prepared from corn with a rice additive of 25% and 50%. Extrudates were prepared using a single-screw extruder TS-45 (L/D=12:1). The range of the temperatures of the extrusion process was 125/130/135 °C. The process was carried out with the variable screw rotation speed of 80, 100 and 120 rpm. This paper presents the results of process efficiency and energy consumption during the extrusion-cooking of instant corn-rice grits. Based on a bidirectional analysis of variance, the process efficiency, regression equation and correlation coefficients were determined for evaluating the impact of the processing conditions on selected properties.

Aerodynamic Properties of Components of Forage for Hay Production

<abstract> <bold><sc>Abstract.</sc></bold> Forages and herbs are composed of leaves and stems that have different drying times, and this complicates the management of product quality. Since their separation during drying could be made by an air stream, an evaluation of some aerodynamic properties of the components in relation to moisture content was made. Terminal velocity, unit density, and projected area of the components of white clover and ryegrass were tested. A test stand was used to determine terminal velocity, immersion was used for the unit density, and photography was used for the projected area. Terminal velocity was in the range 1.0 to 2.0 for clover leaves and 2.0 to 4.0 for clover stems and ryegrass, and Reynolds number was in the range 1000 to 5000 for clover leaves and 5000 to 35,000 for clover stems and ryegrass. The results showed better separation of components at high moisture contents.
