In this article as an object of study is considered the transport system and mechanism of self-organization. The subject of research is social and economic power in the mechanism of self-organization of the transport system. The essence of our suggested scientific hypothesis is that transport system of a different level has to be regarded as a whole system. So it needs complex measurement instrument...
Recommender systems (RS) performance largely depends on diverse types of input that characterize users' preference in the form of both explicit and implicit feedbacks. An explicit feedback is stated directly by an explicit input from users regarding their interest in some options of services or products. Such feedback, however, is not always available. On the other hand, an implicit feedback, which...
The Maximum Diversity (MD) problem is the process of selecting a subset of elements where the diversity among selected elements is maximized. Several diversity measures were already studied in the literature, optimizing the problem considered in a pure mono-objective approach. This work presents for the first time multi-objective approaches for the MD problem, considering the simultaneous optimization...
Anugrah Citra Boga is a food processing industry that produces meatballs as their main product. One of the problems in the company is the distribution of the products. Moreover, the distribution cost was never examined scientifically to obtain the optimal value. By simulating the distribution route to minimize the distribution time, then lower cost of the distribution will be expected. Therefore,...
A fast fault location and isolation scheme for active distribution network with effectively earthed neutral is proposed in this paper. Firstly, the generalized current phase-angle difference (GCPAD) of a zone is defined, and its fault feature is analyzed. Secondly, the fault zone determination method based on the GCPAD is proposed. Thirdly, on the basis of the proposed fault zone determination method,...
Modern supply chain is a complex system and plays an important role for different sectors under the globalization economic integration background. Supply chain management system is proposed to handle the increasing complexity and improve the efficiency of flows of goods. It is also useful to prevent potential frauds and guarantee trade compliance. Currently, most companies maintain their own IT system...
Accompanied by the sharp economic evolution, the amounts of products that are circulating more and more outstanding. Depend on the fact that in the process of delivering goods, businesses need to have professional Logistics to help them promote transferring goods to necessary places many logistics companies have established. Third party Logistics (3PL) companies specialize in integrated operation,...
This research aims to analyse factors that influence behaviours of users in sharing of information on GO-JEK, an online mobile transportation company, in its social media such as Facebook or Twitter. These influencing factors are analysed based on the perspective of attachment theory and cognitive evaluation theory. Data were analysed using the Structural Equation Modelling (SEM). The result of this...
In order for travelers to arrive at their destination comfortably, it is important that they plan their trip carefully. Our motivation in this paper is to free the traveler from tedious planning tasks. Several studies and applications have been proposed to help travelers plan their trip according to explicit preferences, but most ignore implicit preferences. For the first time, to the best of our...
In recent years, maritime freight transportation and the consequent handling of containers are among the most dynamic and growing sectors. The aim of this research is to propose a Decision Support System (DSS) addressed mainly to shipping companies, allowing the choice, even en-route, of the hub port of destination for the successive multi-modal operations. The companies make choices in relation both...
The paper presents an approach to estimate the optimal number of vehicles on public transport line; this approach is based on a simulation model of the process of servicing the bus line passengers. A problem of determining such a number of buses, that provides the minimum cost of transport at the maximum level of passenger service, is quite a complex issue due to the stochastic nature of the transport...
This work focuses on wide-scale freight transportation logistics motivated by the sharp increase of on-line shopping stores and the upsurge of Internet as the most frequently utilized selling channel during the last decade. This huge ecosystem of one-click-away catalogs has ultimately unleashed the need for efficient algorithms aimed at properly scheduling the underlying transportation resources in...
Mobile Internet technology is an important tool and means to improve transportation services. Traditional transport service industry will also be based on the Internet platform to realize the transformation and reconstruction of the operating mode. In this paper, the impact of mobile Internet technology on transportation services industry is analyzed in detail. Moreover, how to create the environment...
The approaches for developing the mechanisms of effective decision making in sea container traffic management based on traffic volumes forecasting by the means of artificial neural networks is investigated. It was found out that the efficiency of the container transport depends on the ratio of import and export of goods which is non-linear. The mechanism of enhancing the effectiveness of the decisions,...
In urban goods delivery, the service quality is affected by number of lorry, distance between two points, road blocking and assigned time of customers, etc. The lower efficiency of human power and delivery time are caused from poor route planning. A hybrid approach of route finding, which is involved in multi-objectives and lorry assignment, is developed for achieving the optimal delivery schedule...
When it comes down to public transport systems, delays are a hot topic. For a quantitative conclusion whether a delay is just an incident or happens on a regular basis, we have to believe in the figures published in the annual reports of public transport companies. However, even if some data is available online, it is quite hard to independently examine these numbers without information technologies...
In this paper, we consider a real-life heterogeneous fleet vehicle routing problem for retail construction material stores. A modified cluster first-route second algorithm is deployed to fit a real-life problem. In cluster first, the clusters of customers compatible with vehicle capacity are grouped together. In route second, the mathematical model is developed and solved by General Algebraic Modeling...
Transporting products from the depot to various destinations is a general problem in logistics world. However, complications arise when the objective is changed from transporting goods to transferring people, as both distance-related costs and man-hour loss must be taken into account. This paper presents a Variable Neighbourhood Search (VNS) based heuristic that helps route planners of an oil and...
This research aims to establish guidelines for selecting position of cassava buying location and assign the appropriate purchase price to cassava purchaser. Nowadays, the quantities of cassava, which facilities obtain, are lower than their production capacity due to high competition among cassava processing manufacturers. Cassava processing factories need to obtain more quantity of raw materials,...
Cement is one of the strategic commodities that supporting acceleration of infrastructure development and economic growth. It forces the cement companies to improve the production process to be more effective and efficient. Therefore, the cement companies are required to understand which of activities can increase the value added to the product. This study aims to minimize wastes in the cement production...
