A Framework to Integrate Prognostics and Health Management into Performance-Based Logistics
Performance-based logistics (PBL) has achieved widespread success as a new logistics strategy, but not all PBL projects have been successful. This article summarizes the reasons for the failure of PBL and the advantages of Prognostics and Health Management (PHM), furthermore, analyses the necessity of integrating PHM into PBL. The innovation of this article lies in the establishment of a process framework to integrate PHM into PBL, and a specific evaluation method is given to evaluate the effect of PBL after using PHM, which make PBL gain more benefits or turn into a victory.

An Object Recognition and Volume Calculation Method Based on Yolov3 and Depth Vision
In recent years, the logistics industry is in its full swing. The demand for logistics is increasing throughout the country, and this rising trend will continue during the following decades. With the substantial increase of workloads, traditional manual ways are increasingly unable to meet the new needs of the logistics industry, therefore new production and transportation modes are becoming imperative. Considering this, a new method was proposed to help detect, recognize and calculate the volume of rectangular objects automatically. In this method, a YOLO-based model was firstly applied to detect the object. Secondly, an RGB-D camera was used to obtain the depth information. Finally, after the length, width and height values were estimated from a single surface, the volume of the object can be calculated. Experimental results showed that the method is simpler and more accurate as compared with traditional three-dimensional reconstruction-based methods.

Kosten- und Leistungsrechnung in der Spedition
Der Kostenrechnung kommt in Speditionen eine hervorgehobene Bedeutung zu. Jedoch wird dieses Gebiet, gerade in kleinen und mittelgroßen Unternehmen häufig vernachlässigt. Dies kann in einer fixkostenintensiven und renditearmen Branche wie dem Speditionsgewerbe schwerwiegende Folgen haben. Auch wissenschaftlich betrachtet ist die \"Kostenrechnung in der Spedition\" ein weißer Fleck. Der Fokus der einschlägigen Literatur liegt klar auf der Industriekostenrechnung. Das vorliegende Buch möchte diese Lücke schließen. Es ist als Lehr- und Übungsbuch konzipiert. Fallstudien sind integriert, um das vermittelte Wissen am konkreten Beispiel nachzuvollziehen. Ein Glossar gibt den Überblick über zentrale Begriffe. Erweitert wurde die Neuauflage um Beispiele zur Auftragskalkulation in der Luft- und Seefracht.

The improvement of sea highway route by using parallel insertion and exhaustive search
Indonesia contains of island and ocean which perform some problems in logistics delivery such as create a gap between west side and east side of Indonesia. A sea highway program were made by president to send logistics to be more effective and efficient. This program has been implemented for four years recently but still has many adjusment such as creating the best route of sea highway. This research try to create a better route of sea highway by using tour constraction to create an initial route in two steps, clark and wright saving matriks and parallel insertion. The second method is tour improvement aims to generate a new route after initial route by using exhaustive search. Five route of sea highway are generated in tour constraction and two route has been adjusted in the tour improvement because of a better score came up. The improvement of fourth route from Depot-Malahayati-Batam-Telukbayur-Depot becomes Depot-Malahayati-Telukbayur-Batam-Depot and second route still being the same but there also another option of route which has 18 score different from the best route score, those are Depot-Sampit-Samarinda-Balikpapan-Pontianak-Depot.

Active learning for data streams: a survey
Online active learning is a paradigm in machine learning that aims to select the most informative data points to label from a data stream. The problem of minimizing the cost associated with collecting labeled observations has gained a lot of attention in recent years, particularly in real-world applications where data is only available in an unlabeled form. Annotating each observation can be time-consuming and costly, making it difficult to obtain large amounts of labeled data. To overcome this issue, many active learning strategies have been proposed in the last decades, aiming to select the most informative observations for labeling in order to improve the performance of machine learning models. These approaches can be broadly divided into two categories: static pool-based and stream-based active learning. Pool-based active learning involves selecting a subset of observations from a closed pool of unlabeled data, and it has been the focus of many surveys and literature reviews. However, the growing availability of data streams has led to an increase in the number of approaches that focus on online active learning, which involves continuously selecting and labeling observations as they arrive in a stream. This work aims to provide an overview of the most recently proposed approaches for selecting the most informative observations from data streams in real time. We review the various techniques that have been proposed and discuss their strengths and limitations, as well as the challenges and opportunities that exist in this area of research.

Last-mile delivery concepts: a survey from an operational research perspective
In the wake of e-commerce and its successful diffusion in most commercial activities, last-mile distribution causes more and more trouble in urban areas all around the globe. Growing parcel volumes to be delivered toward customer homes increase the number of delivery vans entering the city centers and thus add to congestion, pollution, and negative health impact. Therefore, it is anything but surprising that in recent years many novel delivery concepts on the last mile have been innovated. Among the most prominent are unmanned aerial vehicles (drones) and autonomous delivery robots taking over parcel delivery. This paper surveys established and novel last-mile concepts and puts special emphasis on the decision problems to be solved when setting up and operating each concept. To do so, we systematically record the alternative delivery concepts in a compact notation scheme, discuss the most important decision problems, and survey existing research on operations research methods solving these problems. Furthermore, we elaborate promising future research avenues.

The Physical Internet – review, analysis and future research agenda
Purpose
The Physical Internet (PI) is an emerging concept that applies the Digital Internet as a design metaphor for the development of sustainable, interoperable and collaborative freight transport. With the aim of aiding researchers and policy makers in their future efforts to develop efficient logistics systems, the purpose of this paper is to present a review of the existing literature on the PI, to critically discuss the concept and to outline a research agenda.
Design/methodology/approach
The literature review investigates scientific papers, project reports, specifications and other publications related to PI. In total, 46 publications were finally analyzed. The approach used in this paper is technology adoption by firms. The authors examine the PI based on four factors: organizational readiness (technological blueprints), external pressure (promised effects), perceived benefits (business model) and adoption.
Findings
A growing number of strategies, blueprints and specifications have been developed for PI, yet there are no currently developed models that illustrate how the move from the entrenched logistics business models to the PI could ensue. There is a lack of understanding of the business models needed that can involve critical actors and promote the adoption of the PI concept.
Research limitations/implications
While using the internet as a metaphor for reimagining physical transports is certainly exciting, this review and analysis suggest that several research questions need to be addressed before further PI blueprint work is carried out.
Practical implications
The “grand challenge” of sustainability in logistics needs to be addressed and improved, but the authors’ analysis suggests that, to some extent, it is uncertain how the PI will contribute to improving sustainability, and why logistics service providers should engage in PI. Policy makers and practitioners are provided with critical issues to consider in the practical development and adoption of the concept.
Originality/value
This paper provides an outsider and technology-adoption perspective of PI research, as well as important implications for policy makers and researchers.
