Abstract
In the article it is reviewed and modified a method of product life cycle assessment (LCA) with the help of a new stage "market monitoring", which allows at the stage of strategic planning to identify priorities for product release and production technology design. It is also found that the use of OLAP technology enables to visualize not only the stages of "start-release", but also to assess the necessity of termination of further production, using a developed spiral model of product life cycle assessment for virtual instrument-making enterprises. The developed model have shown that when reaching break-even point it should be the right way to conduct strategic planning, modernize the product in accordance with the consumer needs and give the product a new round or complete the project. Development of such models helps to ensure that the product life cycle for virtual instrument-making enterprises can stretch to infinity.
Highlights
In Ukraine, one of the main industries of the economy in the market conditions are mechanical engineering, which defines the scientific and technical policy of the country, ensuring the competitiveness of products and economic security
Discussion of the results of life cycle assessment model Principles of OLAP systems provide a high level of efficiency and effectiveness of the access to large volumes of information in real time and presenting data in the context of different analytical trends transforms data into valuable information that can be used for analytical processing of the information and make grounded decisions in the production process of the virtual instrument-making enterprises
As a result of the research: 1. It was found that the life cycle assessment is an integral part of decision-making
Summary
Communication systems transmit information from a transmitter to a receiver through the construction of a time-varying physical quantity or a signal. Optical communication systems use light rays with a wavelength of 380 nm to 3000 nm region of the electromagnetic spectrum. The spectral efficiency and reliability of wireless optical channels can be improved by using multiple transmitter and receiver elements after the invention of the optical amplifier in the 1990-s. The advent of the optical amplifier heralded a new era of optical communications in which a massive number of wavelength-division multiplexing (WDM) signals can be conveyed over thousands of kilometers [1]. Fiber optic communications are light wave systems that employ optical fibers for data transmission. The natural trend was to study the light wave communication systems, in which
