In the present paper the issue of horizontal cooperation in a road transportation network is tackled. Different road trips belonging to a set of carriers that form a coalition are shared, with the final goal of maximizing the carriers' profit. The higher the number of carriers belonging to the coalition, the greater the possibility of obtaining profitable trip combinations; however, this makes also the cost sustained for managing the coalition increase. In this work, the proper size of the carrier coalition with the final goal of further improving the coalition profit is obtained by using an optimization based scheme. At first, a mathematical model is formulated with the goal of finding the best trip combinations to minimize the total costs for performing trips. Then, a second mathematical model is stated in order to assign both combined and single trips to carriers. This second optimization problem is solved several times for different number of carriers participating to the coalition in order to determine the best coalition size. An experimental campaign based on real data sets has been performed to validate the proposed approach. Various instances considering different number of trips and different values of the coalition management cost have been analyzed.

Question-answering (QA) systems have recently shown impressive results in terms of accurately answering user questions in such situations as domain specific user questions. However, we have identified many real situations where QA systems must cope with not a single question-answering situation but rather a sequence of consecutive questions. In such cases, users often ask questions on the basis of the previous answer they have received, so the context of the questions changes on a certain level. The commonly used method to handle this problem when using a QA system is to append the current question to the previous question (append method). However, the append method is not designed to detect such context changes. To deal with such context changes, we have designed a hierarchical context supplementation QA System (HCSQ). The HCSQ handles consecutive questions by matching the current question with the hierarchical domain knowledge database structure of the previous answer and then supplements the context of the current question with the required keywords. We also show that our method can be further applied to the initial question to supplement omitted context. Experimental results show that our method substantially outperforms the state-of-the-art methods.

The success of an autonomous robotic system is influenced by several interdependent factors not easily identifiable. This paper is set to lay the foundation of a new integrated approach in order to deeply examine all the parameters and understand their contribution to success. After introducing the problem, two cutting-edge autonomous systems for the process of unloading of containers will be presented. Then the STIC analysis, a recently developed method for modelling and interpreting all the parameters, will be introduced. The preliminary results of applying such a methodology to a first study case, based on one of the two systems available to the authors, will be shortly presented. Future research is in the end recommended in order to prove that this methodology is the only way to efficiently and effectively mitigate the risk that stops potential users from investing in autonomous systems in the logistics sector.

A robust structure of an emergency service system is usually designed so that the deployment of given number of service centers complies with specified scenarios by minimizing the maximal value of objective functions corresponding with the particular scenarios. If the problem is modelled by means of mathematical programming and solved by a general IP solver, than the min-max link-up constraints represent an undesirable burden in any integer programming design problems due to bad convergence of embedded branch-and-bound method. Within this paper, we try to overcome the drawback following from the link-up constraints by usage of several techniques based on iterative processing. We provide the reader with a comparison of the original min-max approach to the suggested approach based on the Lagrangean relaxation of the troublesome constraints and subsequent usage of sub-gradient method for Lagrangean multiplier adjustment.

In this paper, an original mixed VMI (Vendor Management Inventory)/RMI (Retail Management Inventory) IRP (Inventory Routing Problem) characterized by zero inventory costs is considered, focusing on a quite typical scenario of multiproduct delivery to a network of retailers distributed over the territory. In this scenario, some retailers have the possibility to place orders on their own (pull retailers), while the orders of the other retailers (push retailers) are generated in automatic, through the original methodology here proposed. The objective is to avoid stock-outs, minimize transportation costs, and equalize the use of transportation resources over the considered planning horizon. The proposed MVRMIRP is formulated as a mixed-integer mathematical programming problem. Then, an original two-step algorithm is proposed, for solving the considered problem.

This paper presents an IoT (Internet of Things) system designed to allow the monitoring and control of parameters of the users' vehicles, anytime and anywhere in the world, through the Internet. The system prototype was developed and tested using an electric vehicle (EV) and the respective sensor systems. The main components of the proposed IoT system are: a Bluetooth Low Energy (BLE) intra-vehicular wireless sensor network (IVWSN); a mobile device that acts both as the vehicle's gateway, connecting the IVWSN to the Internet, and as the vehicle's human machine interface (HMI); an online server/database, based on Firebase; a client, which can be either a mobile device or a personal computer; and a residential wireless sensor network (WSN). The use of a wireless network to collect sensor data inside of the vehicle introduces some advantages when compared with conventional wired networks, whereas the inclusion of a residential WSNs in the proposed IoT architecture allows the provision of additional features, such as automatic control of the EV battery charging process. Experimental results are provided to assess the performance of the developed IVWSN and HMI.

The large-scale management and monitoring of ancient buildings, in particular of churches, is a complex issue for the heritage buildings holders. The scientific and technical communities study new methods to improve these operations through Information and Communication Technology tools. This paper proposes the first steps of an innovative methodological approach to develop an information system that allows the monitoring of many masonry churches using limited resources. The information system consists of a computer platform (named Quality Detection Platform — QDP) and a mobile device application dedicated to the acquisition of large-scale data through Internet of Things (IoT) support. This tool allows recording and reporting structural problems through photographic surveys and additional information provided by the smart devices positioned on the structure: a set of Bluetooth Smart sensors positioned on specific building components. The data collected are processed by the QDP that studies and classifies the critical issues. In order to assess the proposed methodology, the case study of the church “SS. Salvatore” in Bari (Italy) is developed.

Due to change in customer requirements, companies, especially MTO companies, started focusing on the internal flow. Therefore the study of different production planning techniques, particularly order review and release methods, in a pure flow shop is slowly becoming important. Literature shows that research so far is mostly confined in theoretical studies, but there is scarcely any evidence of applying the order review and release methods in a real time company. Therefore, the internal logistics system of a MTO company in Italy is studied. The system follows a pure flow shop configuration. After collecting the data from the company, the different parameters are determined. Two different order review and release methods, limiting, based on heuristics, and balancing, based on optimization model, are applied and compared with the current condition. The simulation results show better performance of balancing method compared to limiting method for the internal flow of the company.

This paper concerns an analysis aimed at choosing the best investments in seaports for improving the rail split modality when transferring goods from ports to final destinations. Starting from a current network infrastructure, already optimized according to previous studies, we show that it is possible to obtain a new rail capacity able to increase the modal split thanks to possible alternative investments. First, a Mixed Integer Linear Programming (MILP) model is proposed; then, a set of possible financial interventions is examined in such a way to obtain a desired rail share for the import-containerized flows. The objective function of the proposed model aims at minimizing the costs of the adopted investments and the overall logistic costs, given by transportation, facility and external components. Externalities include pollutant, noise and congestion factors. The logistic networks originated from the Ligurian ports (Italy) is the test bed of the present research work.
