10.1 Analysis of factors influencing the competitiveness of the STR

Introduction

Road transport plays a rather important role in the country's economy. And in the context of the globalization of the world economy, it is necessary to ensure the competitiveness of all industry in general and road transport in particular. This can be achieved by increasing productivity, more efficient use of resources.

In this regard, the service enterprise must continuously adapt to the volatile service market. Improve the quality of its services. Introduce knowledge-intensive technologies, use the latest technical tools. Conduct training, and staff development. Use advanced technology to organize the technical process. Increase mechanization of works.

Feasibility study of ATP reconstruction.

4.1.1 Redevelopment of ATP production building.

In order to place additional maintenance zone posts inside the production building, it is proposed to:

- expand the production areas of the enterprise by adding a new premises;

- move the accounting planning department, and the food reception room to the 2nd floor;

- combine the vacated rooms with an aggregate mechanical workshop in order to expand it.

These transformations will allow you to place dedicated car maintenance posts in the enterprise, in order to better organize the technological process and increase the production capacity of the enterprise.

4.1.2 For more efficient organization of employees recreation, it is proposed to organize an alley with shops and deciduous trees on the territory of the enterprise. In addition to organizing recreation, this will improve the environmental situation at the enterprise. It is known that at low costs this is economically justified, since the productivity of workers with good rest increases by 15-20%.

Construction requirements

Construction requirements are determined by the process requirements and processes occurring in the automotive service, enterprise planning and regulatory requirements and local construction conditions. These conditions have a significant impact on the choice of building codes, materials and structures of garage buildings.

6.3 Construction of building components

The buildings undergo a number of technological processes, they have a great influence on the choice of building materials and structures of garage buildings. These include foundations, floors, columns, walls, floors, windows, and gates.

6.3.1 Foundation

Prefabricated, reinforced concrete foundations on monolithic cushion. For the partition - prefabricated foundations from blocks for monolithic preparation.

6.3.2 Floors

The floors in the production building are concrete, preparation on a crushed stone base, finishing with a mosaic layer 5 cm thick. To prevent cars from hitting the walls, wheelbarrow sidewalks 15 cm high are installed at the place of the dead end.

6.3.3 Columns

Prefabricated, reinforced concrete, 6 cm high, two or single-column columns for installation of crane-beams.

6.3.4 Walls

Prefabricated walls, reinforced concrete from wall panels at the junction of the gates of the brick wall.

6.3.5 Overlaps

Prefabricated, reinforced concrete, pre-stressed structures, these include: beams with a span of 12 m, hollow reinforced concrete slabs with a size of 1.5 x 6 m, trusses with a span of 24 m.

6.3.6 Windows and Doors

Windows made of plastic double-glazed windows measuring 2m x 4m, glazing of the production case tape 2.4m high, single-sided with a width of 1 m. Double-sided - 2 m.

6.3.7 Gate

The gate rises to the top with a width of 5 m, a height of 4 m. Opening and closing of the gate is done manually.

6.3.8 Roof

The roof is rolled on a gas-concrete insulator with a bulk weight of up to 430 kg/m asphalt brace 5 cm thick, a four-layer roof made of ruberoid on bitumen mastic.

6.3.9 Room Finishes

Cutting of seams between slabs, plastering of brick surfaces, glazing panels with glazing tiles to a height of 1.8 m.

In domestic premises, lime and oil paint are plastered.

The production facilities are whitened with lime mortar. Paint painting to a height of 1,8 m.

Organization of standardization works at ATP

Standardization work involves the development of standards, specifications and other scientific and technical documentation that take into account the norms and requirements that are necessary for this ATP. They go for introduction of progressive technological processes, improvements of control and improvement of quality of control, economy and more rational use of raw materials, materials, the electric power and spare parts. These works include metrological certification of measuring instruments, monitoring of compliance with standards, product quality control.

Based on a set of standards, the enterprise establishes rational interconnected rules, norms and requirements that take into account the specifics of the enterprise.

9.2 Metrological support system for maintenance and maintenance of rolling stock.

The main regulatory documents regulating the activities of the metrological service of the Minavtotransport of the Russian Federation are:

- GOST 1.2576. GSS "Metrological support. Basic Provisions ";

- GOST 8.100271. JCC "Organization and procedure of inspection, audit and examination";

- GOST 8.10373 GSC "Organization and procedure of metrological examination";

- RTM 200RSFSR15005578 "Measuring instruments. General technical requirements for acceptance and operation ";

- RTM 200RSFSR1500276 "Manual on organization and performance of certification and testing of measuring instruments produced at Minavtotransport enterprises."

The objects of testing in road transport are devices in the composition of vehicles, as well as diagnostic and test equipment. One of the activities of the metrological service is the creation and development of its own verification and instrument repair base.

9.3 Comprehensive quality management system of rolling stock maintenance at ATP.

Quality management is one of the main problems of the modern economy. A special set of regulatory documents has been issued, the main of which are: "Integrated Product Quality Management System," "Recommendations for the processing, implementation and improvement of ATP."

The complex quality management system is a set of control bodies and control objects interacting with the help of material, technical and information means in quality management, provides management at all stages. The structure of the quality management system includes all ATP divisions and services. The overall management of the integrated product quality management system is carried out by the director and chief engineer. The procedure for issuing documents of the quality management system, their registration and accounting is established in accordance with RD 410383 "Instruction on registration and accounting of the state, development and implementation of the SMCS." Ministries and departments provide methodological assistance to the enterprise through the system of head and basic organizations for the development of the SMCP.

Conclusion

The diploma project analyzed the existing production organization system. Proposed measures to expand production volumes. The new structural subdivision of the maintenance area has been calculated. The production areas were reorganized and expanded.

The economic efficiency of ATP reconstruction was assessed.

In the section on occupational safety, the analysis of hazardous and harmful factors affecting industrial workers was carried out. Active fire extinguishing system has been developed.

In the design part, an accessory has been developed to increase the safety of working with lifting equipment.

The research part analyzed the impact of the quality of services provided on the competitiveness of the enterprise.
