Assessment of factors affecting the software process improvement in small organizations
Get PDFSoftware process improvement implies a set of complex and systematic activities of software engineering. It requires theory and models established in management, technical and social sciences. The improvement is based on the assumption that the organization if it owns mature and capable processes, would be able to deliver quality software on time and in line with predicted costs. The maturity models are initially aimed for implementation in enterprise software organizations, government organizations and within the military industry. Their complexity and the size make them difficult to use in small software organizations and companies. In such organizations the interest for use and the efforts to make an efficient and effective organization is always presented, though. In this paper, the basic and derived capability maturity models are described and cases from their implementation are analyzed, along with assessment of results of such projects in business practices. The problem of the software process improvement in small organizations is described, extracting the risks and recommendations for its enhancement. These recommendations are provided in order to set up a foundation for implementation of these models in a specific managerial and organizational environment characterized by small organizations

A Proposed outsourcing model for pick-up and delivery processes
Get PDFIn the last few years, we have been active participants in globalization and the rapid growth of online commerce. This trend directly impacts logistics, postal, and courier companies. Challenges are visible in the growth and development of these companies, as well as quality of task execution and the ability to adapt to market conditions. With the impact of the SARS-COV-19 virus on the market, and due to locks during the pandemic, shoppers were forced to buy products online. This effect accelerated the trend of purchases via e-commerce, which increased the number of parcels in the technological phases of pick-up and delivery. These companies are the bearers of the first and last technological phase of shipment transport. Due to the increase in the number of shipments, postal and logistics companies are under great pressure. This is because of certain restrictions introduced during the pandemic, but also because of costs, especially fixed costs in the first and last phase of transport. This paper proposes an outsourcing model for the pick-up and delivery to convert fixed costs into variable ones
Green IoT: sustainability environment and technologies
Get PDFThe Internet of Things (IoT) connects everyone in the smart world, so the energy consumption of IoT technology is a challenging and attractive research area. The development of technology in the field of IoT has changed the way of life and enriched society with its benefits, but we must not ignore the fact that IoT consumes energy, contributes to toxic pollution, and generates electrical waste. To increase the benefits and reduce the harmfulness of IoT, there are increasing tendencies to move towards green IoT (G-IoT). The G-IoT is considered the future environmentally friendly IoT. Greening ICT technology plays a key role in G-IoT and promises many benefits to society such as efficient production, and reducing the energy used to design and distribute ICT devices and equipment. This paper will present a comprehensive overview of G-IoT technologies and strategies that demonstrate work and efforts to build a green and smart world, contributing to a safe and healthy environment, smart and high quality of life based on enabling technologies, reducing pollution, and reducing energy consumption. ICT technologies that enable G-IoT include Green RFID, Green Wireless Sensor Network (GWSN), Green Cloud Computing (GCC), Green M2M (G-M2M), and Green Data Center (GDC). The paper will also present an analysis of the importance of environmental technology processes in sustainable development, exploring the principles and roles of G-IoT in the progress of society through examining its potential for improving quality of life, environment, economic growth, and green global modernization
Impact of Covid-19 on the Logistics Sector of Public Postal Operators in The Western Balkans
Get PDFThe Covid-19 pandemic has a direct impact on the social, economic, political, and other segments of society through a large number of lockdowns in 2020 and 2021. The largest postal and logistics companies as an integral part of the supply chain have been directly affected by the Covid 19 pandemic. Disruption in the supply chain significantly affects the movement of goods and the economic development of countries. This paper investigates the impact of the covid-19 pandemic on the logistics sector, with special emphasis on public postal operators (PPO) in some countries of the Western Balkans (Bosnia and Herzegovina, Croatia, and Serbia). The paper analyzes the movement of express shipments in domestic transport, as well as imports and exports for 2020. There is almost no research on the implications of the covid-19 pandemic on the postal and logistics sectors of Bosnia and Herzegovina, Croatia, and Serbia. The aim of this research is to understand the impact of the pandemic on this sector
Microservice development using RabbitMQ message broker
Get PDFNowadays, when applications are being developed faster with the introduction of agile methodologies and new technologies, microservices are emerging. The microservices make applications easier to create and maintain when broken down into smaller parts, which form a whole application. RabbitMQ acts as an intermediary between the various services. It reduces the load and delivery time on server web applications by delegating tasks that would typically take a lot of time and resources. Message queuing allows web servers to respond quickly to requests rather than being forced to perform complex procedures that can take more time and resources. AMQP (Advanced Message Queuing Protocol) is a message protocol that deals with publishers and consumers like any other messaging system. Publishers produce messages while consumers download and process them. The job of message brokers, such as RabbitMQ, is to ensure that messages from publishers go to the right consumers. To do this, the broker uses two key components: exchange and order. We demonstrated that the style of microservice architecture is an approach to the development of an application as a set of small services, each in charge of its own process and communication with other services
Hybrid Extended Fuzzy AHP and Fuzzy ARAS Methodology for Evaluating Train Organization Systems in Bosnia and Herzegovina
Get PDFThe operational transport strategies of a state are developed as a combination of train organization systems and network usage systems. Due to the central importance of these operational transport strategies, special attention is paid to analyzing their functioning and the conditions under which different combinations of train organization systems and network usage become feasible and commercially viable. This study proposes a hybrid fuzzy approach to multi-criteria decision-making methods for evaluating and assessing train organization systems and network usage in Bosnia and Herzegovina. For this purpose, an extended Fuzzy Analytic Hierarchy Process (E-FAHP) was applied to determine the relative significance of each criterion, followed by ranking train systems using the Fuzzy Additive Ratio Assessment Method (Fuzzy ARAS). To validate the efficacy of the proposed framework, a case study was conducted using a real-world example. The findings demonstrate tangible potential for practical implementation
Application of ICT as a Key Element for Airport Safety and Security Operations
Get PDFAirport risk management is a demanding task as several different areas have to be monitored including outer edges, car parks, terminals, and other passenger facilities. Information and communication technologies (ICT) are key elements for airport operation safety and security. One of the advantages of ICT based systems is they can react better and faster in real time and perform certain tasks at airports. This paper aims to present a safety overview of ICT and multi-agent systems (MAS) usage in the implementation of various airport operations. This paper aims to present a safety overview of ICT and MAS systems usage in the implementation of various airport operations. This paper summarizes a multi-agent concept that highlights their applications at airports such as passenger transfer, baggage management, aircraft handling, and field service through a detailed and extensive literature review on related topics. Much of the information on processes within the airport, processes in air traffic, and the processes of operators, i.e. airlines, is the result of monitoring work on a software development project for individual airports that serves to manage all processes in airports. The analysis led to the conclusion that safety and security in airports can be additionally improved by greater use of ICT as well as greater use of MAS, which ultimately contributes to the optimization of the airport
Development of road infrastructure safety management system according to updates of EU Directive 96/2008/EC
Get PDFThe traditional approach to the analysis of traffic accidents has mostly involved identifying omissions in vehicles and drivers, which led to the occurrence of a traffic accident. However, more recent EU directives dealing with this area emphasize infrastructure failures that may be the real cause of the accident. This approach refers to preventive action, ie the design of such infrastructure that will, in case of failure of the driver, "forgive" the driver his mistake and prevent the occurrence of a traffic accident or reduce the consequences of a traffic accident. To achieve this, a completely new approach to the problem is needed, ie to build, reconstruct and regenerate the road infrastructure according to its real function from the aspect of traffic safety. The realization of these concepts in our area implies primarily the education of all entities that have contact with road infrastructure (designers, managers, auditors, etc.), with emphasis on the fact that savings on the material are significantly less than the savings achieved by reducing the number of accidents, with injured faces and fatalities
