Bearing in mind European Green Deal assumptions regarding a significant reduction of green house emissions, electricity generation from Renewable Energy Sources (RES) is more and important nowadays. Besides this, accurate reliable forecasts RES are needed for capacity planning, scheduling, managing inertia frequency response during contingency events. The recent three years have proved that Machine Learning (ML) models promising solution forecasting RES. In this review, the 8-step...

Problems with inaccurate prediction of electricity generation from photovoltaic (PV) farms cause severe operational, technical, and financial risks, which seriously affect both their owners grid operators. Proper results are required for optimal planning the spinning reserve as well managing inertia frequency response in case contingency events. In this work, impact a number meteorological parameters on PV Poland was analyzed using Pearson coefficient. Furthermore, seven machine learning...

Many construction projects fail to meet deadlines or they exceed the assumed budget. This scenario is particularly common in case of innovative projects, which too late identification a high risk delays and exceeding costs makes potentially profitable project untenable. A level, far level standard non-innovative characteristic feature realization phase projects. associated not only with greater complexity design phases, but also problems application new technologies prototype solutions, lack...

Nowadays, horizontal directional drilling (HDD) technology is one of the most popular trenchless construction methods for installing pipelines under obstacles. Both risk analysis and management are key tools helping to meet today’s challenging project demands connected with quality, deadlines, costs, legal issues. In this paper, a new model based on proactive holistic approaches presented, which an extension from traditional toward complex in HDD projects. Fuzzy fault tree analysis, fuzzy...

Nowadays we can observe a growing demand for installations of new gas pipelines in Europe. A large number them are installed using trenchless Horizontal Directional Drilling (HDD) technology. The aim this work was to develop and compare machine learning models dedicated risk assessment HDD projects. data from 133 projects eight countries the world were gathered, profiled, preprocessed. Three models, logistic regression, random forests, Artificial Neural Network (ANN), developed predict...

The building sector contributes significantly to global final energy consumption and energy-related CO2 emissions. demand for sustainable energy-efficient passive buildings with a minimal ecological footprint has increased due the crisis, climate change, environmental concerns. This need can be met by constructing buildings. However, develop that is truly passive, it required meet many house conditions, negligible typical buildings, which increase project complexity pose challenges risks...

Nowadays, one of the characteristic features construction industry is an increased complexity a growing number projects. Almost each project unique, has its project-specific purpose, own structural complexity, owner's expectations, ground conditions unique to certain location, and dynamics. Failure costs resulting from unforeseen problems in complex projects are very high. Project drivers pose many vulnerabilities successful completion This paper discusses process effective risk management...

Horizontal Directional Drilling (HDD) technology is one of the most popular trenchless construction methods for installing pipelines under various obstacles. The geotechnical risk level HDD projects key parameters when assessing project feasibility and making costing project. It also a starting point introducing management strategy which aims to reduce number installation failures their negative consequences. objective this work was develop new model projects. process carried out applying...

Nowadays, we can observe a growing number of investment projects in the construction industry and environmental engineering, as well interest socially responsible aiming to contribute sustainable development. Interorganizational cooperation engineering is associated with many opportunities risks that continue be challenge for today’s world. The aim this work identify assess relationship-specific risk determinants threatening achieve intended benefit interorganizational develop assumptions...

This paper concerns an important and current problem of taking Corporate Social Responsibility (CSR) initiatives in the specific market conditions COVID-19 pandemic. CSR activities, aimed at combating COVID-19, contribute to creating favorable for sustainable development enterprises entire society. In this work, analysis survey results, interviews with initiatives’ beneficiaries, brainstorm sessions specialists companies’ employees allowed us identify risk opportunity categories, factors,...

Horizontal Directional Drilling (HDD) is a very complex technology.Although the installation of pipelines by means this technology often successful, examples unsuccessful projects are also known.Due to complexity technology, with interaction multiple processes, risks related uncertainties in these processes play important role.These variability underground strata, changing natural environment, changes economic as well limitations equipment, technical disruptions and human factors.This paper...

Abstract Today, in many areas of technology, we can come across applications various artificial intelligence methods. They usually involve models trained on some specific pool learning data. Sometimes, however, the data analyzed by these solutions change its nature over time. This results a decrease classification efficiency. In such case, use techniques to retrain originally reference should be considered. One industries where changes quite dynamically time is broadly defined call/contact...

Nowadays, we can observe a growing interest in passive buildings due to global climate change, environmental concerns, and energy costs. However, developing building is associated with meeting many Passive House requirements, which results their increased complexity as well challenges risks could threaten the successful completion of project. Risk management key tool enabling today’s challenging house project’s demands connected quality, costs, deadlines, legal issues. In this paper, new...

Horizontal Directional Drilling (HDD) technology is a highly complex process connected with high risk and uncertainty due the variability underground strata, often limited access to specialised equipment, dynamic natural environment, technical disruptions, human factor changes in economic environment that further complicate gathering of reliable information data.This work presents new evaluation model tailored for HDD technology, which failure mode effect analysis (FMEA) modelling were...

Global climate change and increasing energy costs as well environmental concerns have led to increased worldwide interests in passive buildings, which minimal consumption reduced impact. Passive houses design construction processes are much more complex than it is the case of buildings developed traditional standard they associated with many risks. In this work, selected problems related were presented. The risks divided into three categories: architectural design, installation at building...

Wooden construction constitutes a specific branch of the building industry that focuses on high-quality materials, developed sense aesthetics connected with comfort and functionality, concern for ecology durability. This type has positive effect human quality life. article modular frame technological aspects wooden houses built according to Canadian or Scandinavian technologies. Taking weather conditions countries into consideration, timber is popular material, which, when preserving certain...
