Methods of evaluation of production and technological work with shipbuilding

Оценка и анализ производственно-технологических работ судостроительных предприятий обусловлен необходимостью обеспечения конкурентоспособности вновь создаваемых объектов морской техники с показателями качества на уровне лучших мировых образцов с одновременным повышением темпов технико-экономического развития их производства. Названная проблема диктует необходимость адекватной оценки состояния технического оснащения производства, а также наиболее эффективных направлений вложения средств на техническое перевооружение. Техническое оснащение производства во многом зависит от уровня автоматизации, механизации технологических процессов, объёмов ручных работ, конструктивно-технологических особенностей создаваемых объектов морской техники, серийности производства и т.д. Для судостроения, судового машиностроения с учётом единичного и мелкосерийного производства характерна высокая доля ручного труда, особенно при выполнении механомонтажных работ. В статье предложен принципиально новый подход к оценке производственно-технологических работ (уровней технического оснащения производства) судостроительных предприятий. Приведены результаты расчётов и оценки на примере переделов (видов работ) механомонтажного производства для группы отечественных судостроительных предприятий. Предложенный метод оценки производственно-технологических работ (потенциалов) универсален для любых видов судостроительных и машиностроительных работ. Evaluation and analysis of production and technological works of shipbuilding enterprises is conditioned by the need to ensure the competitiveness of newly created marine equipment facilities with quality indicators at the level of the world's best samples, while increasing the pace of technical and economic development of their production. This problem dictates the need for an adequate assessment of the state of technical equipment of production, as well as the most effective ways of investing funds for technical re-equipment. The technical equipment of production largely depends on the level of automation, mechanization of technological processes, the volume of manual work, the design and technological features of the created objects of marine equipment, serial production, etc. For shipbuilding, marine engineering, taking into account single and small-scale production, a high proportion of manual labor is characteristic, especially when performing mechanical installation work. The article proposes a fundamentally new approach to the assessment of production and technological works (levels of technical equipment of production) of shipbuilding enterprises. The results of calculations and estimates on the example of repartitions (types of work) are given mechanical assembly production for a group of domestic shipbuilding enterprises. The proposed method of evaluation of production and technological works (potentials) is universal for all types of shipbuilding and machine-building works.

The paper considers the possibility of using unified dry mixes for machine-building enterprises with small-scale and single-piece production of castings. Dry mixes for production of expendable molds and rods have been developed. Their distinctive feature is that cladded CMC high-silica sand is used as a filler, and powder-like LST are used as a binder. All the ingredients of the mix are products of domestic and Russian production, are not scarce, are not expensive in price, are simple and safe to use. Experimental-industrial tests of the proposed dry mixes were carried out, and a pilot batch of castings was produced in the amount of 5 tons of good casting (small shaped cast-iron casting). Taking into account the specificity of the foundries at enterprises with single-piece and small-scale production, the features of their technical equipment, an engineering solution, focused directly on this segment, has been developed and proposed. The engineering solution relates to the manufacturing processes of casting molds and rods production, and consists in the development of formulations for dry foundry mixes. A distinctive feature of the formulations is: simplicity in use, versatility in functionality, reliance on the domestic resource base, which means that it is affordable, not expensive, and environmentally friendly, safe both for production personnel and for the environment, in the area where the industrial enterprise is located.

Material is presented on the formation and development of agricultural engineering in Russia in the 19th - early 20th centuries. The research materials were archival funds, Internet resources, historical works, and literature. The prerequisites and features of the emergence of agricultural machine-building enterprises, namely repair shops and factories, against the background of social changes are examined. The information on the creation and development of Russia’s ﬁ rst agricultural machine-building plants is given and analyzed. Prior to the abolition of serfdom, 60% of enterprises manufacturing agricultural tools belonged to artisanal workshops, and 10% – to small factories. This volume accounted for less than 50% of the market needs, the rest of the equipment necessary for agriculture was supplied by foreign plants. By 1880, the number of domestic enterprises increased to 340. In 1913, agricultural machinery production already accounted for 20.5% of the total volume of Russian mechanical engineering. The largest agricultural engineering plants were located in the south and in the central part of Russia. In 1913, the share of southern plants amounted to 53%, the share of the plants of central provinces – 20.5% of the total output (by value). In other regions, artisanal production of equipment and machinery of simple designs prevailed. After World War I, agricultural machinery production declined to 8% from the 1913 level. Enterprises created in the second half of the nineteenth and early twentieth centuries became the basis of agricultural engineering in Russia. The following features of the Russian agricultural machine-building industry are noted: small-scale production, limited nomenclature, manufacture of tools of simple designs, focus on the local market, lack of export, dependence of production volumes on the yield, lack of narrow specialization of enterprises, seasonal character of production.

Organizational Problems

The need to increase labour productivity and improve the competitiveness of engineering products, as well as to increase high-tech exports, are urgent tasks for the development of industry in the Russian Federation. The creation of competitive products implies flexibility in the approach to the consumer, which leads to an increase in the share of enterprises operating in conditions of small-scale production. The purpose of this study is to assess the reserves of productivity growth at machine-building enterprises of small-scale and unit-type production in the Ural region. Research has shown that organizational factors, such as the automation of production preparation processes, the use of photo-timing studies in the conditions of small-scale production, have a significant impact on labour productivity. In this case, the solution of organizational problems helps to create informational database for introduction at the enterprises of mechanical engineering complex life cycle management of products (the PLM).

Role Of The State

In Vietnam, the construction of hydropower projects has contributed significantly in the cause of industrialization and modernization of the country. The place where hydropower projects are built is mostly inhabited by ethnic minorities - communities that rely primarily on land, a very important source of livelihood security. In the context of the lack of common productive land in resettlement areas, the orientation for agricultural production is to promote indigenous knowledge combined with increasing scientific and technical application; shifting from small-scale production practices to large-scale commodity production. However, the research results of this article show that many obstacles in the transition process are being posed such as limitations on natural resources, traditional production thinking or the suitability and effectiveness of scientific - technical application models. When agricultural production does not ensure food security, a number of implications for people’s lives are increasingly evident, such as poverty, preserving cultural identity, social relations and resource protection. Since then, it has set the role of the State in researching and building appropriate agricultural production models to exploit local strengths and ensure sustainability.

The prevention of Diabetic Mellitus (DM) and its complications is the main aim of this study, in addition to the training of lotion foot care application and the development of small scale industry. The research team delivered knowledge in the form of training on Diabetic Mellitus, healthy food, treatment and prevention of complications, and small-scale production of cosmetic products. The aim of this study was to determine the correlation between training on diabetic and lotion foot care application as preventive measures against diabetic complications on the patient's blood glucose levels in the community of residents in Banyuurip Jaya, Surabaya. It was expected from this training that the knowledge of the residents increases and people living with diabetic undergo lifestyle changes and therefore blood sugar levels can be controlled. The parameters measured in this research were blood glucose levels, the anti diabetic drug types consumed, and compliance on diabetics. This study used the data taken from 60 patients with DM over a period of one month. Questionnaires and log books was used to retrieve data and changes in blood glucose levels in diabetic patients. The results showed the demographic data of patients with type 2 diabetic of 85% female and 15% male, with the range of patients aged of 61-70 years of 46.67% and had history of diabetic (90%). The history of drugs consumed by respondents was anti diabetic drugs such as metformin (40%), glimepiride (33.37%) and insulin (6.67%). In addition, the increased knowledge of DM patients after being given the training compared to before training was shown in several questions in the questionnaire. A statistical analysis using t-test analyzed a correlation between training provided in order to enhance understanding of the patient, as well as correlation with blood glucose levels. A paired T-test showed that there was a relationship between the knowledge of trainees before and after training (p less than 0.05). An interesting result was that there was no relationship between blood glucose levels before and after training provided (p> 0.05).

In the article a common semi-Markov mathematical model is considered that allows one to investigate the productivity and reliability of various technological processes of mechanical assembly production. The proposed model allows to study, inter alia, technological processes of manufacturing parts with screw and assemblies of threaded connections. Mathematical apparatus of the research is the theory of semi-Markov processes with a common phase space, which operates with a common kind of random variables distribution functions. If the considering process in the system is a subsystem located on a higher level of hierarchy, the hierarchical model for compatibility with each other levels as output simulation parameters required distribution functions. In the proposed model, based on the decision of the Markov renewal equations depend not only on the torque characteristics, but also the distribution function of time per unit of output service according to different kinds of undervalued failures.
