“…The classic transport task is defined as the linear programming problem [1][2][3][4][5], which is the subject of a number of publications on new methods [6,7], algorithms [8], or on optimization techniques [9] of the existing decision node. Freight transport is often a decision problem in transport systems [10] affecting both the key performance indicators [11][12][13][14][15] and the level of customer service [16][17][18][19][20].…”

Optimization of the Delivery Time within the Distribution Network, Taking into Account Fuel Consumption and the Level of Carbon Dioxide Emissions into the Atmosphere

The evolution of changes in shopping in the modern society necessitates suppliers to seek new solutions consisting of increasing the efficiency of transport processes. When it comes to controlling the flow of goods in modern distribution networks, planning and timely deliveries are of particular importance. The first factor creating a competitive advantage involves the tendency to shorten order delivery times, especially for products with a short shelf life. Shorter delivery times, in turn, extend the period of effective residence of the product “available on the shelf”, increasing the likelihood of its sale. The second component in line with the Sustainable Development Strategy consists of aspects related to the protection of the natural environment, in particular those related to car transport. In this case, the fuel consumption and the level of emitted toxic substances (including carbon dioxide) are analyzed and assessed. Bearing in mind the above, this article presents the problem of optimizing the delivery time within the assumed distribution network and its solution, enabling the company to develop and optimal plan for the transport of products with a short shelf life. The paper proposes a model that takes into account minimization of the delivery time, while estimating the values of fuel consumption and CO2 emissions for the variants considered. The means of transport were medium-duty trucks. Three variants of the assumptions were considered, and algorithms implemented in MS Excel and MATLAB software were used to perform the optimization. Using the MATLAB environment, a more favorable value of the objective function was obtained for the variant without additional constraints. On the other hand, the algorithm implemented in MS Excel more effectively searched the set of acceptable solutions with a larger number of constraining conditions.

“…Another major aircraft manufacturer, the European company Airbus, was also forced to adapt production to new conditions. However, given the geographical distribution of production, each specific situation was significantly influenced by a group of measures taken by the national government aimed at combating the spread of infection and supporting the economy[20,21,22].In the face of a fall in demand for vehicles, many large companies re-equipped their production facilities for health care needs, for the production of personal protective equipment or mechanical ventilation devices, which helped in the fight against the spread and consequences of infection but did not help to compensate for lost profits. Experts say that one of the potential solutions for the aircraft industry is the possibility of reaching an agreement with governments and regulators to reduce the maximum permissible life of aircraft, which will entail an accelerated replacement by carriers of the fleet of relatively old and expensive wide-body aircraft in operation with new models.…”

The purpose of the research in this article is to investigate the main trends in the development of the different industries during the COVID-19 pandemic, to identify the main problems facing the different industries in the context of the global crisis, as well as to form the basic concepts necessary for a real recovery of the global industry. The authors identify the main problems facing the aviation industry in the developing world crisis and possible ways to solve them. As a working hypothesis, it is proposed to form the basic concepts necessary for preparing and implementing operational measures to restore passenger and cargo aviation. Considering the main threats facing the aviation industry during COVID-19, the article proposes the organizational and economic mechanisms to restore the industry. Furthermore, several recovery scenarios are considered, considering the relevant factors that have a particular impact. Next, a novel mathematical model for pharmaceutical products, which are the most important in COVID-19 pandemics, is proposed. Moreover, the model considers the uncertainty, and a robust optimization approach is applied. The study is based on a comprehensive analysis of documentary data provided by government agencies in several European countries. An analysis of global and Russian passenger traffic for Q1-Q4 (quartile) of 2020 and a development forecast for Q1-Q2 of 2021 is provided. The scenario problems facing the aviation industry in the context of the COVID-19 crisis are identified. There are key concepts necessary to prepare and implement effective measures to restore the aviation industry.

A methodology of analysis and evaluation of the selected indices of the helicopter readiness used in the Polish Navy is presented in this paper. These objects are the multi-purpose helicopters of the Polish and Russian production, performing mainly the rescue tasks. A mathematical model was based on the source databases covering a period of 2 years, which were developed in the form of the multi-format MS Excel spreadsheets. While considering the operating environment and a specificity of the performed tasks, an event-based model of the operation process was proposed in this paper, which enables to evaluate selected indices of readiness. Due to the specificity of the individual types of renovations and repairs, the calculated measures of the readiness were enabled in a multi-faceted manner, that is, they were referred to three separate operating periods covering the current operating period, the entire (i.e. two-year) studying period including extended renovations and the entire studying period including extended renovations and repairs. A broader approach enabled to calculate the functional and technical indices of the readiness of the helicopter.
