Item type:Publication, Access status: with files , Auction design in strategic freight procurementPurpose: This article aims to derive options for auction design in strategic freight procurement from the related literature and synthesize them into a design framework. Methodology: The proposed framework is based on a comprehensive literature review on auction design in strategic freight procurement. After conceptualizing the research topic and defining the scope of the review, a broad literature search was conducted. Inclusion and exclusion criteria were applied to select the literature. A coding scheme was used to extract the data. Findings: The literature review reveals design features and associated design options for each feature. This paper additionally identifies shortcomings in the scientific literature for auction design in strategic freight procurement. Based on this, the further need for research is derived. Originality: The literature to date has focused primarily on describing the auction process and solving the Winner Determination Problem as a subset of the auction process. In contrast, the specific auction design (e.g., bid types, lane design, number of auction rounds) is only considered in a fragmented way. The proposed framework fills this research gap by synthesizing design options from the freight procurement literature.Publicationtype: Conference Paper201 317 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , An approach to analyzing shippers' transportation managementPurpose: The purpose of this article is to present an approach to analyzing the organizational design of shippers' transportation management from a process perspective. Methodology: The proposed analysis approach is based on a comprehensive literature review on transportation management. The literature is categorized by horizontal, vertical, and internal organizational design strategies as well as process levels. Findings: The literature review reveals organizational design strategies and processes of transportation management. Furthermore, by transferring the results into an approach to analyzing the organizational design of a transportation management, it is shown that processes are shaped by organizational design strategies, which can lead to a variety of process variants. Each of these process variants, in turn, influences the performance of a transportation management organization. Originality: The revealed organizational design strategies and processes contribute to explanation-oriented and design-oriented research in the context of transportation management. The proposed analysis approach further provides a methodological contribution for shippers dealing with the optimization of their transportation management.Publicationtype: Conference Paper207 247 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Impact of Port Layouts on Inter-Terminal-Transportation Networks(epubli, 2020-09-23); ; ; ; Purpose: Major seaports consist of several terminals with different functions. The different locations of terminals in relation to each other influences the organization of inter-terminal transportation as well as transports into the hinterland. The focus of this study is to understand how terminals are arranged in relation to each other to draw conclusions about the effect of the terminal locations on processes and trans-ports. Methodology: The paper provides a comprehensive overview for the locations of terminals and depots within a port. Based on this, a detailed analysis is carried out to develop a classification scheme for ports, which categorizes them according to their geographical characteristics. Findings: Based on the examples of characteristic ports and terminals, we provide findings regarding advantages as well as barriers to transport containers within ports. The aim is to determine the impact of geographical characteristics of ports for handling port-internal traffic. Originality: The existing literature provides an overview of ports and maritime net-works, as well as various port concepts. Furthermore, different approaches for the design of container transports between terminals are discussed. However, there is no overview of the geographical location of terminals and depots in ports and their impact on inter-terminal transportation.Publicationtype: Conference Paper437 406 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Defining the quota of truck appointment systemsPurpose: Truck appointment systems (TAS) are a widely used method to alleviate peaks in truck arrivals at container terminals in seaports and in the hinterland. One big advantage is the opportunity to reduce operation costs for the terminals and the truck queue length in front of the terminal gate. This study aims to analyze and classify different approaches used in science and industry to determine the quota of allowed trucks per time window. Methodology: A comprehensive systematic literature analysis is applied to identify the different approaches to determine the quota of time windows in science and in industry. Findings: The results of the study show that many approaches have been based on experience and are mostly used to improve individual terminals rather than the port as a whole. Methods used to improve and analyze interrelationships are mainly methods of mathematical optimization and simulation. Originality: The question under consideration was mostly only marginally considered in existing investigations, even though it has a major impact on the success of a TAS. Furthermore, only individual solutions have been examined so far and not the suitability of the approaches compared.Publicationtype: Conference Paper619 416 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Equipment selection and layout planning – literature overview and research directionsPurpose: When container terminals are planned or converted, among others the most suitable container handling system needs to be selected and the appropriate terminal layout needs to be designed. These two planning activities are mutually dependent and affect the costs and future operational performance. This leads to the question of how to arrive at a (near-)optimal solution for given criteria. Methodology: A mapping review is conducted to investigate how the container handling system is selected and how the terminal layout is designed. Literature is examined regarding the employed methodology, the performance indicator(s) to optimize, and the way terminal layout and equipment selection have been jointly considered. Findings: Various methods have been used to assess a suitable container handling system and the appropriate layout. Commonly, mathematical optimization is used to arrive at a suggestion and simulation is the tool to evaluate proposed decisions. Aspects such as handling costs, travel distances, or ecological factors are sought to be optimized. Originality: Several literature reviews in the past years investigated approaches to the plethora of scheduling problems at container terminals. Here, the two strategic planning activities equipment selection and layout planning are presented in detail. This publication focuses on how the dependency of the two activities has been handled in literature.Publicationtype: Conference Paper355 466
