The most important focus in the design and manufacture of computers is to ensure the quality of construction. The quality computer products - it is not only the result of the production process, it also formed at all stages of design (including construction) and operating computers.
Indicators of quality design computers can be divided into several groups, key among which are the following: the appointment, reliability, tehnologichnosti, standardization and unification, ergonomic, aesthetic, patent and legal, environmental and safety performance, transmission and economic.
Indicators appointment characterize benefit from using computers for the purpose and its applications. They show the functionality, technical excellence and the appointment of computers, its composition and structure. Typically, these indicators are the technical characteristics of computers, for example: the number of simultaneously performed by teams, the management system of commands, notation, performance, way of presenting data, bit the type of input information, type of memory and its characteristics (capacity, the cycle of treatment, time and sample etc.), characteristics and the number of peripheral devices, the types and number of channels input / output and its characteristics (the speed of data transmission, etc.), power consumption, massogabaritnye characteristics, etc.
Indicators of reliability characterize the possibility of computers to perform a given function, keeping in time values set performance indicators to the extent necessary, appropriate given regimes and conditions of use, maintenance, repair, storage and transportation. The most important are the figures for the computer infallibility, durability and maintainability keeping characterizing opposition to construction of external shocks and create an enabling environment for preventing and detecting the causes of injury and address them.
Safety is a requirement for the computer continuously maintain fitness (with all the requirements for the main parameters in a given time) for some time. Durability - feature computers maintain fitness in carrying out maintenance and repairs before the onset of limiting condition associated with the continued inability, for various reasons, the use of computers for the purpose. Keeping - it is an opportunity computer continuously maintain fitness (good) condition during and after the storage and (or) transportation in certain specified circumstances. Maintainability - adaptable computers to the prevention, detection and removal of failures and malfunctions, through maintenance and repair. The most frequently used indicators of the reliability of computers is the likelihood of trouble, failure rate, time between failures, recovery time, etc.
Indicators tehnologichnosti characterize the effectiveness of design and technology solutions to ensure high productivity in manufacturing, maintenance and repair computers. Manufacturability design, in principle, determine the cost-effectiveness of launching products in production. Her assessment is mandatory pre-development of technological processes of production computers. In general, under the technological design refers to the combination of its properties, which guarantees defined in terms of production and exploitation of the best labor costs, resources, materials and time when technological preparations for the production, manufacture, maintenance and repair, compared with those of similar structures, with established quality indicators.
Handling design for manufacturability is constructors and technologists at all stages of design and construction. If necessary, the developed design documentation before making the required changes. The criteria for evaluating tehnologichnosti construction products are indicators of tehnologichnosti across the entire range of benchmarks specified in the technical task.
Under the unified system of technological standards of pre-production (ESTPP) are two types of tehnologichnosti products: production, which reduce the cost and time to design and technological preparation processes of production and manufacture of the product, and operational, which manifests itself in reducing the cost and time for technical maintenance and repair products.
The main factors determining the requirements for tehnologichnosti design are: the type of product (part, assembly unit complex, set), the type of production and level of development of science and technology. Rating tehnologichnosti can be quantitatively and qualitatively. Good evaluation precedes quantitatively determine its feasibility and describes the general design of dignity based on the experience of the artist. Quantifying the express system of indicators that are used to compare different versions of the design in product design, determining the level tehnologichnosti necessary for predicting and calculating benchmarks tehnologichnosti.
The product manufacturability estimated rate of labor, materials and the cost of construction, operation manufacturability - kontroleprigodnosti performance, interoperability, accessibility, quick to object and rates tehnologichnosti etc. are closely related measures of standardization and unification of characterizing the degree of use in particular the development of standardized computer components, assemblies, blocks and other components, as well as the unification of parts design computers.
The need to replace in the manufacture of computer designs for more advanced, improving their reliability and quality requires the unification of most technical and technological solutions to ensure compatibility and interoperability designs in the process of creating new and modernization of already produced by industry.
Unification (low degree of standardization) is to reduce the diversity of structures that perform the same computer or similar functions. Unification exposed as mechanical parts, assembly units and load-bearing structures, and the element base.
Standardization as a final stage of unification is a necessary prerequisite for the creation of modern computer technology level. High rates of development are not possible without advanced nature of standardization in relation to the production of developed products, without basing it on the best achievements of domestic and international technology.
A special meaning in the creation of computers has wide harmonization and standardization of the basic (generic) structures (structural systems). The importance of harmonization and standardization in the design of computers are also indicators of Application describing the significance, repeatability and continuity of design.
Ergonomic figures describe a system of "people - computers - Wednesday." For many electronic computing products, these figures may be one of the most important.
In turn, ergonomic indicators are subdivided into Hygienic, anthropometric, physiological and psychological.
Aesthetic indicators characterize the artistry, expressive and original works of computers, harmony and structural integrity, appropriate forms and computer design style, color and decorative solution computers, etc.
Patent law indicators used to assess the purity of the patent and patent protection for computer design.
The environmental performance indicators and characterize the safety level of harmful impacts on the environment, resulting in the manufacture and maintenance products (environmental indicators), as well as the design, with its leading manufacturing and maintenance of human security (safety measures).
Figures reflect the adjustment for transmission design computers for transport, as well as the preparatory and final Technological transactions related to transportation.
Economic indicators characterize the costs of research and development work on the development of computer design, the production and operation and economic efficiency in the operation of computers. This is a special kind of indicators to assess the manufacturability and maintainability design, level of standardization, NONINFRINGEMENT, etc.
Note that between different groups, there are linkages to be taken into account when designing a computer. For example ergonomic and aesthetic impact on productivity performance computers, creating a convenience for operators and allowing them with the same psychological tension to introduce more information per unit of time, reduces the likelihood of erroneous actions operator, etc. Indicators of standardization, along with direct links to the value of products affect their serial production, market demand, obsolescence, etc. A similar impact and utilization of new constructive solutions, such as NONINFRINGEMENT.
