In education, for educational instruments scientific writing is a very important thing. It requires an information management skill, information management is a library search, which can be done through a computer and guided by the internet. It can also be through the quality of reading used as a reference for scientific writing. In addition, in producing a paper also must know the management of writing, not only required to pay attention to the rules of standard language, but also must be able to convey ideas and ideas well and meet scientific criteria, such as making a quote or reference list used. This paper was written with the aim of improving the quality of research through reading material, making notes and avoiding plagiarism, references using the Harvard system for journals, books, and articles. Management of citing articles either CD or internet, writing, editing, storing references electronically, writing bibliography, and quotations.

The article presents new models and methods for estimating the residual service life of an autonomous energy system, using the functional operational risk criterion (FOR). The purpose of the article is to demonstrate a new method of durability evaluation using the fuzzy logic and soft computing framework. Durability in the article is understood as a complex property directly adjacent to the complex property of system resilience, as understood in the Western practice of assessing and ensuring the reliability of technical systems. Due to the lack of reliable homogeneous statistics on system equipment failures and recoveries, triangular fuzzy estimates of failure and recovery intensities are used as fuzzy functions of time based on incomplete data and expert estimates. The FOR in the model is the possibility for the system availability ratio to be below the standard level. An example of the evaluation of the FOR and the residual service life of a redundant cold supply system of a special facility is considered. The transition from the paradigm of structural reliability to the paradigm of functional reliability based on the continuous degradation of the technological parameters of an autonomous energy system is considered. In this case, the FOR can no longer be evaluated by the criterion of a sudden failure, nor is it possible to build a Markov’s chain on discrete states of the technical system. Assuming this, it is appropriate to predict the defi ning functional parameters of a technical system as fuzzy functions of a general form and to estimate the residual service life of the technical system as a fuzzy random variable. Then the FOR is estimated as the possibility for the residual life of the technical system to be below its warranty period, as determined by the supplier of the equipment.
