The article provides an overview of the principle of the pump D630-90, as well as methods for studying the real conditions of technical support to improve maintainability and optimize technological processes and systems. A technological process for the restoration of the shaft of a centrifugal water pump has been developed and an algorithm for managing it has been proposed, on the basis of which the system for energy-efficient management of the recovery area has been implemented. Also in the article some questions of use, metal-filled compound SK812, and also application of ultrasonic processing of a surface of a shaft of the centrifugal water pump of mark D630-90 are mentioned and considered. The developed technological process of pump shaft restoration showed that it is characterized by simplicity, it fits well into the production process of repair and can be widely used in repair shops.

In recent years, the Italian national institute of statistics (Istat), together with most National Statistical Institutes, is progressively moving from traditional production models based on the use of primary source of information - represented by direct surveys - to new production strategies based on the combined use of different primary and secondary sources of information. As result, new multisource statistical processes have been built, that guarantee a major improvement of both amount and quality of information about several phenomena of public interest. In this context, the Total Process Error (TPE) framework has been recently proposed in literature for assessing the quality of multisource processes. The TPE framework represents an evolution of the Zhang’s two-phase life-cycle approach and it additionally includes an operational tool to connect the steps of the multisource production process to the phases of the quality evaluation framework. TPE framework can be used both to support a multisource process design and to monitor an entire production process, in order to provide key elements to assess the quality of both the processes and their statistical outputs. In the present work, we describe as a case study in the new context of Istat production of official statistics the use of the TPE framework to support the process design of the Register for Public Administrations.

The authors propose a synergy of expert approach methods through the Systematic layout planning (SLP) and Analytic Hierarchy Process (AHP) as tools for the shipyard production process design towards an optimal material flow, in combination with Simulation modeling (SM). Most production process designs are based on the conventional methodology of comparison initiating with benchmarking. Such approach can be misleading. For more reliable and efficient results, the approach suggested by the authors uses a combination of the mentioned three methods within the frame of an expert approach. Firstly, the Systematic layout planning is used for generating a larger number of suboptimal shipyard production process design alternatives. Then, these alternatives are analyzed through an objective decision making tool to reach an optimal material flow alternative. Further, such optimal alternative is tested and evaluated by Simulation modeling (SM). Finally, the presented methodology is confirmed on a case study as a viable approach to an efficient and reliable shipyard production process design.

Interview Survey

Production process design hybrid real processors opinions is vital important. Many production processes design did not consider processors needs, resulting in many failure products. Glutinous rice industries have their own particularity of production process. Glutinous rice product is a product which is a raw glutinous rice material hybrid from food processing. In Chinese, Japanese, Indian, Korean, etc. societies, glutinous rice products are an important rice product and staple food. Glutinous rice product processors have to face variable raw material (glutinous rice) costs, hence, if they know the trend of glutinous rice products and products diversity, then this would easily gain better profits when they produce these glutinous rice products. This research tries to build a better production processes through processors depth interview, aiming at glutinous rice processors for examples. In this study, a profit formula was constructed. Through in depth interview survey, there were 12 processors in Taiwan visited during 2012. It showed that health, convenience and tourism factors potentially obtained the most profits when processors produced these glutinous rice products. These raw distribution data sets of glutinous rice processors costs would be a foundation of production process design references.

Cutting Processes

The main goal of energy-efficient manufacturing is to generate products with maximum value-added at minimum energy consumption. To this end, in metal cutting processes, it is necessary to reduce the specific cutting energy while, at the same time, precision requirements have to be ensured. Precision is critical in metal cutting processes because they often constitute the final stages of metalworking chains. This paper presents a method for the planning of energy-efficient machining processes based on numerical simulations. It encompasses two levels of planning flexibility: process adjustment and process design. At the process adjustment level, within the constraints of existing machines and tools, numerical simulations of orthogonal cutting are used to determine cutting parameters for increased energy efficiency. In this case, the model encompasses specific cutting energy, tool wear, chip geometry, and burr shape. These factors determine the energy and resources required for the chip formation itself, tool replacements, cleaning and deburring and with that the overall energy efficiency and precision. In the context of process design, with the ability to select machines, machine configurations, tools, and cooling systems, numerical simulations of cutting processes that incorporate machine and tool conditions are applied in the planning of energy-efficient machining. The method is demonstrated for the case of drilling processes and supported by experimental investigations that identify the main influences on energy efficiency in drilling.
