A Fuzzy Expert Model for Availability Evaluation
Each technical system within itself carries the great potential danger of possible occurrence of failure and damages. Mining machines are characteristic by great investment values, costs of unplanned shutdowns, complex working conditions, and environment and workers hazards. Systematic monitoring of the mining machinery is of great importance for the management of the mining companies. Availability is the overall concept of quality of service. Includes information regard to operating state, an idle state, a standby state and shut down. The ......

Determining the Availability of Continuous Systems at Open Pits Applying Fuzzy Logic
This work presents a model for determining the availability of continuous systems at open pits by applying fuzzy logic and fuzzy inference systems. The applied model was formed by the synthesis of independent partial indicators of availability. The model is based on an expert system for assessing the availability of continuous mining systems. The availability of the system, as a complex state parameter, is decomposed into the partial indicators, reliability, and convenience of maintenance, and the fuzzy compositions, used ...системи, континуални систем експоатације, површински коп, рударство, расположивост, фази логика, max–min композиција, min–max композицијаMiljan Gomilanović, Miloš Tanasijević, Saša Stepanović.

Примена ПСП пумпи за експлоатацију вискозних флуида
Алекса Трифуновић (2024)Производња парафинске нафте се током историје одвијала уз помоћ дубниских клипних пумпи, све до појаве ПСП система који су показали боље каратеристике и већу ефикасност. Функционални дизајн пумпе омогућава производњу вискозних и абразивних мултифазних флуида, уз ниска капитална улагања. У раду је анализирана проблематика рада укључују губитке протока флуида, производњу песка, оштећење клипних шипки и тубинга и сам притисак на дну бушотине.
