An approach to greener overseas transport chain planning in FVL

The article deals with a very topical issue of environmental suitability of complex transport chains. Overseas transport chains in finished vehicle logistics (FVL) consist of a series of transport routes in which they successively combine rail, road and sea transport. It is necessary to know the input parameters and their impact on the operation of FVL, especially with the aim of evaluating the air pollutants produced and the energy efficiency (EE) achieved. The article gives a systematic approach in defining input parameters and their evaluation for efficient green transport chain planning. The applicability of the approach is demonstrated on an ongoing FVL of the export flow of luxury vehicles from Europe to Asian markets. Transport chains from four production sites in Central Europe to two loading ports in Koper and Bremerhaven, and in maritime RO-RO transport to four Asian unloading ports are analyzed. The results of the study show the need for more comprehensive planning of export FVL, including environmental assessment at the planning stage. Significant savings in energy consumption and reduction in GHG (greenhouse gas) emissions can be achieved by shifting cargo flows to the southern transportation route. The article enriches the current research on sustainable operation of FVL and provides applied results for infrastructural adaptation of the southern transport route.

Assessment of factors influencing the stability of Ukrainian export based on the fractal analysis

The article considered the assessment of the sustainability of the export flow of Ukraine. It was determined that the markets of Slovakia, the Russian Federation, Germany, Poland and Lithuania possess longterm memory. Also, the main factors that affect the sustainability of export have been analyzed. Among cultural factors, a weak correlation was demonstrated by Long Term Orientation, Indulgence and Power Distance according to the Geert Hofstede method. At the same time, the cultural patterns according to the S. H. Schwartz method did not show a correlation with the long-term memory of product export. On the stability of the export flow, the role of the linguistic distance and the factor of the diaspora presence have been assessed. It was proved that the gravitational effect has the greatest impact on the stability of export; Power Distance, linguistic distance and the factor of the diaspora presence have the negligible impact as well.

Brazilian position in the international fresh fruit trade network

The fruit growing activity is of great importance for Brazilian agribusiness as the country is the third largest fruit producer in the world. Despite this notability, the fruit market presents obstacles especially related to international trade. Thus, the present study sought to determine the positioning and evolution of Brazil in the international fresh fruit market. Data used in the research were obtained from the Food and Agriculture Organization of the United Nations (FAO) (1986 to 2017) and the World Bank (2018), using metrics of export flow, quantity and income of countries related to the main fruits exported by Brazil in the first quarter of 2020. Data were manipulated, transformed into figures and graphs for better visualization of information. The Brazilian position in the in the ranking of fresh fruit exports was not very dynamic during the evaluation period, being dependent on the demand from high-income European countries.

Globalization and Foreign Trade of Pakistan with D-8 Group

<p><em>Globalization has made the world smaller and flatter which is called “the death of distance”</em><em>.</em><em> This phenomenon has brought considerable increase in international trade in recent past. Many developing countries have been benefitted from the fruits of globalization and many other like Pakistan have lagged behind in the race. Pakistan is suffering persistently from trade deficit since 2003 and by the same point of time India, Sri Lanka and Bangladesh which share similar socio-economic conditions to Pakistan: are experiencing upward trend. This study investigates the popular theory “the gravity model of trade” in the context of Pakistan’s export flow to D-8 group. The gravity trade model has been innovated by introducing overall </em><em>G</em><em>lobalization </em><em>I</em><em>ndex (GI) which led to improve explanatory power of gravity model. This research, in panel setting has used annual data ranging from 2003 to 2013, by employing advance estimation technique PPML, Estimator. The empirical results of the study infer that GDP, population and distance confirm the basic gravity model. While the globalization Index and contiguity variables are against the expected signs. Therfore, it is concluded that Pakistan need to explore new destinations specially should target the developing countries for its exports.</em><em></em></p>

Reliability Analysis of Relevant Radom Variables in Pedestrian Evacuation Study in Underground Transportation Hub

In this study reliability theory was applied in evacuation time of pedestrians in the subway, especially taking the correlation of pedestrian speed and pedestrian flow coefficient into account. Firstly, the traditional evacuation time design formula was regarded as research model. Statistical distribution of pedestrian speed and pedestrian flow coefficient in the model was analyzed .Thus the reliability limit state equation was built. Then the evacuation time’s reliability probability was obtained according to the checking point method of generalized random space. At last the process of how different factors influence the reliability was analyzed. Results show that we should consider the correlation between pedestrian speed and export flow rate when correlation is big (absolute value is greater than 0.5, for example).Our conclusions will contribute to related research and the formulation of actual planning.

Study of Prevention and Control on Fire Safe Evacuation in a Large Public Places

This paper USES the probability analysis method, Markov model to predict fire personnel safety evacuation design rationality in public places. In a large public fire safety evacuation for example is analyzed, the results showed that: Markov model can be scientific, accurate and effective to predict the export flow density of the extreme cases within the limited time and emergency exit door set minimum traffic. In order to ensure the fire after the personnel to evacuate to the safe zone within the time allowed.

Application Research of Electrical Supercharger for Improving Performances of Diesel Engine under Plateau Environment

Against the problems that the working performances deterioration of high-power engine under plateau environment, an electric supercharger system is designed by applying modern control and sensor technology, and after testing performances of the electric supercharger multiple times, the system is optimized according to the internal flow field distribution and export flow characteristics. The tests prove that the system which controlled by electric control device can achieve transient air supply rapidly. Then increased the air flow rate significantly, and it is able to recover the most of the power in low speed part, which propose the feasible way to the problem of engine intake air shortage under plateau environment.

AN AGGREGATE TRANSPORT DEMAND MODEL FOR IMPORT AND EXPORT FLOW SIMULATION

This paper presents a system of models for the estimation of international (import/export) freight flows through a partial share approach. It allows us to simulate attraction, production, distribution and modal split for the estimation of modal Origin-Destination matrices in quantities. Aiming at predicting long term effects for strategic planning, the modelling system has been specified through easy-to-capture variables represented by level-of-service attributes and aggregate socio-economic variables. The calibration was carried out by using a set of available data in Italy that allowed us to consider import/export flows for different freight types given by the aggregation of classes provided by European NST/R classifications.
