INVENTORY MANAGEMENT IN THE ORGANIZATION OF LOCOMOTIVE PARK SERVICE

Planned warning system for locomotive repair has almost exhausted its potential.This was facilitated by the rapid deterioration of the technical condition of the locomotive fleet andinfrastructure for both repair and operation. Rolling stock renewal is almost non-existent, and thereis interest in providing railway services due to rising tariffs and low levels of comfort.On the contrary, some foreign railways consider the planned warning system exhausted,especially in compliance with all requirements for maintenance and repairs, timely modernizationmeasures.But at the same time, the policy of monitoring the technical condition of manufacturers to formthe infrastructure for the organization of repair and modernization of the series of locomotives isgradually developing. The first scientific researches in this direction were devoted to substantiationof strategy of interaction of traditional approaches and those which bring considerable differencesfrom traditional. This is the adoption of a strategy for the distribution of operational and repairfunctions of locomotive enterprises, and when, together with manufacturers, repair plants and depots,the need to transfer repairs to service centers is determined.At the same time, large centers are being formed that provide service services for the regionsof operation, namely, organize the monitoring and audit of the enterprise and ensure the organizationof rolling stock repairs.Without a clear organization of the supply system, the organization of locomotive service, whichrequires the selection of the optimal procurement procedure and stocks.The introduction of a new system of maintenance and restoration of the locomotive fleet on theprinciples of service requires a clear organization of the supply of spare parts for repairinfrastructure. The system considers the solution of the optimization problem of the balance of profits andlosses in the creation of stocks for locomotive service.Assuming that the process demand was mostly random, it is proposed to introduce a targetfunction that takes into account the definition of the law of distribution of demand for spare parts,based on the minimum of the given measurements for their acquisition and storage. With this in mind,it is proposed to create an ideology of «virtual storage» to optimize stocks and their costs.

Load Balancing in Cloud Computing Empowered with Dynamic Divisible Load Scheduling Method

The need to process and dealing with a vast amount of data is increasing with the developing technology. One of the leading promising technology is Cloud Computing, enabling one to accomplish desired goals, leading to performance enhancement. Cloud Computing comes into play with the debate on the growing requirements of data capabilities and storage capacities. Not every organization has the financial resources, infrastructure & human capital, but Cloud Computing offers an affordable infrastructure based on availability, scalability, and cost-efficiency. The Cloud can provide services to clients on-demand, making it the most adapted system for virtual storage, but still, it has some issues not adequately addressed and resolved. One of those issues is that load balancing is a primary challenge, and it is required to balance the traffic on every peer adequately rather than overloading an individual node. This paper provides an intelligent workload management algorithm, which systematically balances traffic and homogeneously allocates the load on every node & prevents overloading, and increases the response time for maximum performance enhancement.

BIM modeling for sustainable design and energy efficient construction

The goal of sustainable construction is to improve the energy efficiency of a building, which today is a challenge for software developers, builders, owners within the constraints of time, cost, provision and resources. Building functional, sustainable, safe, comfortable and easy-to-use buildings will increase consumer demand. The problem of implementing sustainable construction lies in the division of responsibilities and tasks from the relevant specialists. This article explores the role of Building Information Modeling (BIM) in reducing fragmentation among professionals at every stage of construction. The possibility of using a virtual storage of information using BIM is analyzed, which provides easy access to data and their exchange in real time. Thus, BIM provides a professional platform for working in an integrated environment at any stage of the building construction process. When analyzing Russian and foreign sourcesthe prerequisites are being created for the future research required to generate improvements towards sustainable construction.

A Security Framework for Enhancing User Experience

In this paper, we present a novel framework that enhances user experience for their daily computing activities while being protected from cyber threats. The conceptual security framework also targets two additional goals: enabling end-users to experiment software applications before making a decision for a real installation, and serving as a testing environment for both research scholars and security practitioners to analyze and predict potentially malicious activities. The framework introduces three modes of operations (full lockdown, partial lockdown, and administration) and a virtual storage that provides a safe, secure, and reliable computing environment for end-users. We also present three use cases that show the applicability of their framework in a real-world environment.
