Co-using Infrastructure for Sustainability in Maritime Transports

Sustainable transportation systems require optimal co-use of infrastructure. Different means of transportation use infrastructure for its operations. At certain points these means of transportation utilizes the same infrastructure, such as e.g. passages on or under bridges, which require co-modal coordination. To create means for such coordination, situational awareness needs to be established among involved actors by digitalization and principles for information sharing. In this short paper, a co-modal transport system, GOTRIS (Göta Älv River Information Services), is used as a basis for a deeper understanding of the challenges for reaching an optimal co-use of infrastructure. By integrating information from maritime transports as one source in this coordination effort, sustainable transportation systems can be reached. This challenge is formulated in a research question and a preferred approach is stated

Öst till väst, hemma bäst? : En kvantitativ studie om marknadens reaktion vid svenska offentliggöranden av nordiska förvärv

Tidigare forskning är inte helt enig om ett offentliggörande av ett företagsförvärv skapar mervärde för det förvärvande företagets ägare. Framför allt tycks det råda delade meningar kring om den abnormala avkastningen skiljer sig mellan offentliggöranden av inhemska förvärv och gränsöverskridande förvärv. Studien syftar därför till att undersöka om abnormal avkastning uppstår när ett svenskt företag offentliggör ett inhemskt förvärv och om avkastningen skiljer sig från svenska gränsöverskridande förvärv inom Norden. Genom en eventstudie innehållandes 84 förvärvsannonseringar mellan 2015–2019 på Stockholmsbörsen undersöks marknadens reaktion. Studien finner att det uppstår abnormal avkastning vid offentliggörandet av inhemska förvärv. Vidare finner studien vissa belägg att inhemska förvärv genererar högre abnormal avkastning än gränsöverskridande förvärv

Enabling Port Efficiency by increased Collaboration and Information Sharing–Towards a Standardized Port Call Message Format

To enable just-in-time operations, the various actors engaged in sea transport related actions need to contribute to the creation of common situational awareness. PortCDM (Port Collaborative Decision Making), as one of the concepts of Sea Traffic Management (STM), is a key enabler for reaching the full effects of STM as safe, efficient and sustainable transport from berth-to-berth. The purpose of PortCDM is to provide a basis for the collaboration between key actors within the port and towards its surroundings by enabling situational awareness. Such establishment of situational awareness and use of the information from different sources requires a standardized way of capturing the communication within the port and to port-related actors. In this paper the constituents of PortCDM are introduced followed by a proposed way to conceive Port Call Messages with its different facets

Service and Communication Infrastructure for Sea Traffic Management

The introduction of Sea Traffic Management services relies on infrastructures that enable trustworthy information sharing and service provisioning/consumption processes. For this purpose, a federated and regulated approach to information sharing and service distribution is proposed. Such an approach would position the governance of different services in the continuum of hierarchical (i.e.command and control) to market-driven approaches. In this paper the maritime infrastructure framework is presented and applied to Sea Traffic Management. The full potential and large-scale implementation would come when the same framework is applied in different areas of application that rely on information sharing, service interaction, and (digitized) actor collaboration

Punctuality as performance metrics for efficient transportation systems

Transportation systems are ecosystems building on a high degree of co-production of value performed by multiple actors. In order to guide involved actors and ensure expected performance it becomes necessary to have an agreed performance metrics. Beside operational capacity for the transportation systems as such it is believed that punctuality as a performance metrics would be a solid base enabling different actors to take appropriate actions in planning, realizing, and evaluating their actions in relation to the expectations among involved actors (including beneficiaries) of the transportation system. In this paper, underlying mechanisms for punctuality are explored as the basis for an efficient transportation system

Sea Traffic Management – Concepts and Components

This paper gives an overview of all components making up the Sea Traffic Management (STM) concept. STM builds upon information sharing in the whole maritime transport chain, where informationis shared as early as possible about intentions and reached states. Sea System Wide Information Management will provide an infrastructure for a regulated and federated approach to informationsharing. The functional sub-concepts are described: Strategic Voyage Management, Dynamic Voyage Management, Flow Management and Port Cooperative Decision Making. We will elaborate on how they complement each other and which benefits each of them has in regards to safety, environment and efficienc
