Transaction Management System

Transaction Management System for processing banking messages in SEPA and SWIFT formats including transaction queue management and message management.

I developed the core front-end for the web application components: and . The development is based on recursive functions, the message structure is regulated by classificators and counterparties. As this is a banking project, it was decided to reject all dependencies from third-party libraries, therefore the technological solution is based on the library developed with pure javascript. Such an approach allowed the implementation of flexible solutions for specific project needs. For example, the system was developed in such a way that it can be manipulated in the same manner as green screens due to flexible UX implementation that includes keyboard navigation through all the management processes including screens navigation. Additionally, the clients were using green screens that allowed to conclude, that very likely old monitors are in use. Therefore, the solution got a flex grid layout based on Bootstrap to provide a fully responsive interface to support old clients and be comfortable for the new ones. One of the biggest advantages and challenges of this project was the strict requirements on “WHAT” should be implemented, and no restrictions on “HOW” that need to be achieved. Because of this, I’ve got freedom in development that led to new challenges, researches and exceptional results.

Museum of Romanticism in Opinogora

www.muzeumromantyzmu.pl
The website for the state institution "Museum of Romanticism in Opinogora". The institution requested a solution that would provide the opportunity to build the customizable pages of the website by non-professional users. Because of such requirements, it was decided to build the project based on a WordPress solution. However, as the requirements were beyond the default WordPress functionality, the new theme for WordPress and multiple plugins were developed.

To allow the best user experience, the theme got a myriad of additional settings with a simple user-friendly interface, such as: theme settings, footer and banners builder, event-calendar positioning, elements styling and typisation, gallery blocks and image processing, Google map blocks, etc. The main challenge of this project was that to fulfil all client requirements, the WordPress solution had to be expanded with extra functionality for both server-side and client-side processing developed with PHP and JavaScript. Such development involves multiple researches and tests, nonetheless, this implementation allowed to deliver a flexible and fully customizable solution.

Digitals Checker

www.github.com/eman-on/Digitals_Checker
The main goal of this development is to provide the opportunity to “check” the projects of the company before delivering them to the customer. The developed program contains functionality for detection of "none specified" layers that are not described in qualifier and functionality for checking of all layers in the project to have the same parameters as in qualifier.

Additionally, parameters and objects of the layer can be inspected, modified and removed. In the output of this procedure, the project is standardised in response to the requirements, which increase the quality of the project and the company as well. Usually, the procedures highlighted above are performed manually, which might result in drawbacks and mistakes due to the “human factor”. Such issues can be avoided by reasonable automation and optimization, which was successfully implemented in this project.

Point Cloud Modelling

In the context of the need for reconstruction in cramped conditions in the historical part of cities, the design and engineering of existing buildings and structures can be challenging and time-consuming. This project involved reconstruction of the church in Solomianka park, Kyiv, Ukraine. Step-by-step modelling of such a complicated structure would take a lot of the designer's time. In this regard, I decided to apply a technology to create a model of the church and prepare it for Web environment processing. The cloud of points was made by Leica P30 ScanStation for the modelling of the structure. The was made with Autodesk Revit and a model of the building was created. Small parts of the model were modelled in Blender and SketchUp. The resulting model can be imported into the Web environment. The is done with 3Ds Max and Photoshop.

Abstract

The integration of Building Information Modeling (BIM) and Geographic Information Systems (GIS) within the Web environment is a promising approach that greatly enhances the capabilities of the aforementioned environments through the wide range of technology solutions used on the Web. This paper aims to reveal the trends of research in BIM, GIS, and Web integration and discuss the challenges and potential opportunities of such integration in terms of the most common uses in construction. The bibliometric analysis used as the method, compared to conventional literature reviews, reduces the likelihood of subjective judgments. The methodology used is based on a set of five research questions. To answer these, bibliographic coupling is used to analyze the publications datasets, specifically, co-citation networks, co-authorship networks, and the co-occurrence map of keywords. This review contributes to the field in raising awareness of the knowledge composition of BIM, GIS, and Web integration in the last decade, dominant research topics, the most recent trends, and the most pressing issues and use cases analyzed in the current studies related to BIM, GIS, and Web integration, thus identifying gaps and defining future research areas on the topic. The research shows that the number of developments focusing on BIM, GIS and Web integration has been continuously growing with a sudden increase after 2016. The study also revealed that the research work in this area consists of disjointed and fragmented research studies and has been conducted mainly in isolated clusters. Gaps and critical areas for future research include BIM, GIS, and Web interoperability solutions, standardization, BIM model processing and performance optimization, data exchange and storage.

Abstract

The developers of the construction project assess the economic feasibility of the project at early stages of project development and analyse possible alternative solutions. The absence of a detailed project at this stage constitutes an obstacle to accurate decision-making. The article discusses the possibilities of a deeper analysis of future property characteristics and a more accurate assessment of the rational building location at the early stages of project development. The approach presented in article employs Building Information Modelling (BIM), Geographic Information System (GIS) and proposes Quantitative View Assessment (QUVIAS) method for window visibility analysis in the Web environment. The way of determining the window view coefficient and building view coefficient proposed in QUVIAS method can help decision-makers to make more accurate decisions during selection of a project development strategy. The experimental analysis proved the usefulness of the proposed QUVIAS method in assessment of the rational building location and prediction of project revenues.

Abstract

The lack of reliability of decisions made in an uncertain project environment poses risks to decision-making and, consequently, leads to unreliable decisions that have a negative impact on sustainable urban development. In addition, based on different objectives trade-offs need to be found between environmental, social, economic categories. The compromise between different objective functions must be found that can help the decision maker choosing a particular solution according to the requirements. Uncertain data defines the rationality modeling and decision-making of future projects and strategies. This problem is especially relevant if decisions are made by a group of people with different interests, goals and ideas. Models with exact values do not objectively describe possible options under such conditions. Multi-criteria decision models based on fuzzy logic needed for solving problems in such conditions. Such models allow to combine the opinions of different interest groups and help finding a more objective solution. The paper presents an approach that combines the multiple criteria analysis based of fuzzy numbers, BIM and GIS environments. The window view coefficient determined using BIM and GIS and included in the set of criteria. The proposed approach applied in multiple criteria analysis of rational building locations.

Abstract

Any large-scale construction project is inconceivable without the use of a crane for lifting heavy items. The selection of the tower cranes and finding the best position for each crane saves time and money and improves work safety. Performing such an intensive analysis manually, comparing different cranes using many criteria is tedious, time-consuming work. This paper presents an original approach for crane selection based on visibility analysis in the BIM model integrated with the Web environment. The described decision support algorithm involves analysis of crane positioning in the condition of real-world representation model, analysis of crane operator viewport based on the line-of-sight in GIS analysis, crane jib reach analysis. The presented approach allows analysing movable and static crane types, calculate the percentage of the visible and reachable parts of the building, compare crane alternatives and different crane positions.

Abstract

Geographical information systems (GIS) and Building information modelling (BIM) provide digital representation of building, its elements and environment. BIM focuses on micro-level representation of buildings and its elements, and GIS provide macro-level representation of the external elements of environment. Their combination can provide a comprehensive view of a built environment based on integrated data. There is an opportunity to make BIM and GIS unity not only to combine them in a single project but also to make a fully merged environment with difficult associations that extend the capabilities of both. Paper presents method that allows visualization and processing the BIM model in the web browser, external processing and analyzing, easy sharing and visualization, linking the 3D model and attribute information, working with the BIM model and GIS data, digital City mapping and etc. The developed method creates rich future for full BIM software products with all manner of functions and tools that will work through the Internet without installations, distributives, additional programs. The introduced technique can be used as a new part for BIM execution planning.

Abstract

The paper presents the approach that extends the opportunities of Web environments in BIM model processing and allows implementation of the bigger amount of analysis that is based on the object’s positioning. With the developed relations, the objects in the BIM model can be considered not just like independent 3D objects in the WebGL environ- ment but as objects that are linked between each other and can act by the rules that defined to each type of the objects. Correlated co-ordinates will be useful for the architects, building operators and facility managers who use the BIM model for the management of the building and its components. This method can be used to increase the effectiveness of space management, clash detection, relocation management and space programming as well as existing conditions mod- elling and lighting analysis can be done in a way that is more efficient due to possibility of implementation of the survey coordinate system that will give the coordinates to each object in the scene.
