Podstata inženýrské práce

Hesla z wikipedie:

 

Engineering is the discipline and profession of applying technical and scientific knowledge and utilizing natural laws and physical resources in order to design and implement materials, structures, machines, devices, systems, and processes that realize a desired objective and meet specified criteria. The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET[1]) has defined engineering as follows:

“[T]he creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under specific operating conditions; all as respects an intended function, economics of operation and safety to life and property.”[2][3][4]

One who practices engineering is called an engineer, and those licensed to do so may have more formal designations such as Professional Engineer, Chartered Engineer, or Incorporated Engineer. The broad discipline of engineering encompasses a range of more specialized subdisciplines, each with a more specific emphasis on certain fields of application and particular areas of technology.

 

An engineering design process is a process used by engineers to help develop products. the engineering design is defined as

… the process of devising a system, component or process to meet desired needs. It is a decision-making process (often iterative), in which the basic sciences, mathematics, and engineering sciences are applied to convert resources optimally to meet a stated objective. Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing, and evaluation.

This process can be divided up into a ten-step process, which includes identifying a need, defining the problem, conducting research, narrowing the research, analyzing set criteria, finding alternative solutions, analyzing possible solutions, making a decision, presenting the product, and communicating and selling the product. This process is not universal for all engineers or all processes. Individuals utilize their personal knowledge and experiences to follow the path to design success.
