Many modern businesses use computer-aided design, or CAD. There are a large number of suppliers of such solutions. The features and capabilities of data design systems, and in particular presented by specialized AT the appropriate destination, can be very different. What is the essence of CAD? What are the nuances of the development of these systems?

What is computer aided design?

CAD — it's automated systems that are designed to implement a particular information technology implementation design. In practice, they represent a technical system, allowing, thus, to automate, to ensure independent functioning of human processes that make up development projects. Depending on the context, a CAD might be:

- software used as the main component of the relevant infrastructure;

- a set of human and technical systems (including those that require the involvement of CAD in the form of software) used by an enterprise to automate the development of projects.

Thus, it is possible to arrive at a wide and a narrow interpretation of the term in question. It is difficult to say which one applies in business more often, it all depends on the scope of use of CAD, those tasks that are designed to solve these systems. For example, in the context of a single production hall at CAD is likely to be understood by a particular program for computer-aided design. If we are talking about strategic planning of enterprise development, this concept will probably fit more large-scale infrastructure, sagastume in order to improve the design of various projects.

Designing automated systems of information processing management

It is Worth noting that CAD is the abbreviation, which can be decoded in different ways. In the General case, it corresponds to the phrase "computer-aided design”. However, there are other variants of transcripts corresponding abbreviations. For example, it may sound like a “automation system design work”.

In English, the Russian term CAD in meaning corresponds to the acronym CAD, in some cases — CAX. Consider in more detail the many ways in which can be created computer aided design in mechanical engineering, and other fields.

The goal of creating a CAD

The Main purpose of the development of CAD — improving the efficiency of enterprises, solving various production tasks. In particular related to engineering design. Improving the efficiency in this case may be due to:

- reduce the complexity of the design process in the production;

- reducing the duration of the projects;

- reduce the cost of design works and the costs associated with the operation;

- ensuring improvement in the quality of infrastructure design;

- reduce the costs of modeling and testing.

computer-aided design of control systems

CAD is the tool to achieve the marked advantages due to:

- automation of documents;

- effective information support to professionals involved in developing projects;

- apply the concepts of concurrent engineering;

- the unification of different solutions;

- the implementation of the strategic design;

- the use of mathematical modelling as an alternative to expensive tests;

- improve the quality of business management processes;

- optimization of design methods.

Let us now Consider what structure can be represented in CAD.

Structure CAD

Computer-aided design of technological processes, for example, may include the following components:

- the complex of automation elements;

- software and hardware infrastructure;

methodological tools;

elements support the functionality of CAD.

Distributed approach, according to which in the structure of CAD should be allocated to various subsystems. A key is considered

- operating subsystems that support the operation of the main designing components, CAD, infrastructure responsible for the processing of data, maintenance of SOFTWARE;

- designing the subsystems, which, depending on the correlation with the development object can be represented with the object task, or invariant, that is associated with the implementation of specific projects or a combination of several.

computer-aided design of technological processes

CAD — this system, which includes certain functional components. Consider their features.

Components CAD

Computer-aided design of control systems and industrial infrastructure, as we already know, consists of different subsystems. In turn, their components are components that provide the functioning of the respective elements of CAD. For example,it can be one or the other program, file, hardware. Components that have common characteristics, form a means of ensuring design systems. Such can be represented by the following basic forms:

support, which is a combination of various technical tools such as computers, network components, measuring instruments;

mathematical models that combine these or other algorithms that are utilized to address different tasks;

- software-system, application;

- information, representing a collection of data, what is needed in order to implement the design;

linguistic models, which are a set of different languages that are used in CAD to reflect information about the design;

- methodological support, which is a set of approaches to the functioning of CAD, different methods of selection of technological concepts for optimal results in the implementation of certain projects;

organizational security, which represented the main sources that define the structure of project documentation, as well as the characteristics of the automation system and the way in which should reflect the results of the projects.

Automated systems design data processing

Automated systems design, information processing can be classified according to various criteria. Consider their specifics.

Classification CAD

Among the common criteria for the classification of CAD — an industry the purpose of the respective systems. Thus, there are:

- computer-aided design infrastructure engineering;

- CAD for electronic equipment;

- computer-aided design in the construction industry.

The First type of CAD is used in a wide range of industries — in the automotive industry, aircraft industry, shipbuilding, in the segments of manufacture of various consumer goods. The relevant infrastructure is used in order to design individual parts, and various arrangements using various approaches in the framework of parametric design and modeling.

The Second type of CAD software used for designing-the-shelf electronic equipment, as well as its individual elements, such as processors, integrated circuits and other types of hardware.

The Third type of CAD is activated in order to design various buildings, structures, infrastructure and facilities.

The Following criterion, which can be classified computer aided design, programming, — the purpose of CAD. Thus, there are:

- design tools, operated in the automation of two-dimensional or three-dimensional geometric models, the design documentation;

systems used to develop various design drawings

- CAD generated for geometric modeling;

the system is intended for automation of calculations in the framework of engineering projects, and dynamic simulation;

- CAD designed to conduct computer-based analysis of the various options on projects.

- the automation tools used for technology optimization projects;

- CAD software, used for automation planning.

It is Worth noting that this classification should be regarded as provisional.

The Automated system of technological design can include the widest range of functions among those listed above, and not only. A specific list of capabilities of CAD is determined primarily by the manufacturer of the system. Consider what, in principle, the tasks it can solve.

Development of computer-aided design

Development CAD

The Design of automated information processing systems, control, programming and implementation of other functions aimed at improving the efficiency of development projects in different industries — a process which is characterized by a high level of complexity and requires those involved to implement a significant investment of resources-labor, financial. Experts identify several basic principles in accordance with which can be developed in CAD. Among those:

- unification of

- complexity -

openness

interactive.

Take a closer look.

Unification as a principle of development of CAD

Working with CAD systems as to their stage of development and the period of use of the relevant infrastructure requires adherence to the principle of unification, according to which, certain decisions can equally well and with similar algorithms implemented in the different industries. This principle implies that people using a familiar CAD module or, for example, methods of the automated design in one environment will easily be able to adapt them to the specific application in other circumstances.

Unification of CAD has a value and from the point of view of development of the enterprise - the manufacturer of the system: the more universal will bemodules and approaches that the business offers to the market, the more intense may be his height, the higher the competitiveness and the willingness of new customers to cooperate.

Complexity as a principle of development of CAD

The Next principle, which describes the design process of automated systems-complexity. He suggests that the manufacturer of the CAD will be able to endow its product components that will allow its user to solve tasks at various levels of project implementation. This aspect is perhaps the key terms of the competitiveness of the product and exploration of new markets. But it should be borne in mind that even the most comprehensive solution must meet certain key principles of the development of CAD. Among those — openness.

Openness as a principle of development of CAD

Openness in this context can be understood in different ways, but in all cases, its interpretation would be appropriate. The development of computer-aided design — a process which should primarily be characterized by openness, in terms of the formation of the feedback between the manufacturer of the CAD and its users. Man, using an appropriate system must have the ability to inform its developer on the challenges identified, the peculiarities of the functioning of CAD in a variety of conditions to convey the brand manufacturer for their suggestions about improving the product.

Openness in the development of CAD can also be expressed in the willingness of the manufacturer to carry out active monitoring of technological developments, including competing manufacturers, to keep track of various trends. In this case, the leading role business can play not only technology division, but, for example, marketing companies, PR specialists, managers responsible for the negotiations of the company with partners.

Openness in the development of CAD software — it is also the willingness of the manufacturer of the system for direct dialogue with other suppliers, which again may be its direct competitors. The exchange of technologies that create products through which can be implemented effective computer-aided design of control systems, industrial infrastructure, engineering, as well is an important factor of increase of competitiveness of the brand, who supply the CAD in certain segments of the market.

Interactivity as a principle of development of CAD

Another important principle of creating CAD — interactivity. It primarily involves the creation by the developer of the system interfaces, maximally simplifies the procedure of their engagement, and carry out the necessary communications with other users of CAD.

Another aspect of interactivity — ensuring appropriate interaction between the various modules of computer-aided design through the formation of industrial infrastructure.

It Can be noted that the principle of interactivity is closely linked to the first — unification. The fact that the exchange of data on those or other interactive procedures will be most effective if the necessary standardization of the interaction between different subystem. This can be expressed in the unification of file formats, documents, procedures, language engineering approaches in the development of certain projects.

Especially important considering the principle plays in CAD, through which the automated design of information systems. The scope of CAD is characterized, in particular, a high degree of user needs appropriate infrastructure:

- in a regular, dynamic interaction among themselves;

- ensuring linkages between a large number of modules CAD;

- the implementation of optimization and various online procedures;

- operational reporting.

Only if sufficient interactivity of computer-aided design users are entitled to expect an effective solution to such manufacturing problems.
