Konferensbidrag (refereegranskat)abstract
- In this paper we propose to use components for managingthe increasing complexity in modern vehicular systems.Compared to other approaches, the distinguishingfeature of our work is using and benefiting from componentsthroughout the development process from early designto development and deployment, and an explicit separationof concerns at different levels of granularity. Basedon the elaboration of the specifics of vehicular systems (resourceconstraints, real-time requirements, hard demandson reliability), the paper identifies concerns that need to beaddressed by a component model for this domain, and describesa realization of such a component model.

Towards Component Modelling of Embedded Systems in the Vehicular Domain
- 2008
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The complexity of software and electronics in vehicular systems has increased significantly over last few years - up to the point when it is difficult to manage it with existing development methods. In this paper we aim at using components for managing the complexity in vehicular systems. Compared to other approaches, the distinguishing feature of our work is using and benefiting from components throughout the whole development process (from early design to development and deployment). Based on the elaboration of the specifics of vehicular systems (resource constraints, real-time requirements, hard demands on reliability), the paper identifies concerns that need to be addressed by a component model for this domain. It also outlines basic features and characteristics of such a component model and discusses how relevant existing formalisms and component models relate to it and how they could be reused within the proposed approach.

Towards a Unified Behavioral Model for Component-Based and Service-Oriented Systems
- 2009

Konferensbidrag (refereegranskat)abstract
- There is no clear distinction between service-orientedsystems (SOS) and component-based systems (CBS). However,there are several characteristics that could let one considerSOS as a step further from CBS. In this paper, we discussthe general features of CBS and SOS, while accountingfor behavioral modeling in the language called REMES.First, we present REMES in the context of CBS modeling,and then we show how it can become suitable for SOS. Wealso discuss the relation between our model and the currentstate of the art.

A Classification Framework for Component Models
- 2007
-
Ingår i: Proceedings of the 7th Conference on Software Engineering and Practice in Sweden, Göteborg, Sweden.
-
Konferensbidrag (refereegranskat)abstract
- The essence of component-based software engineering is embodied in component models. Component models specify the properties of components and the mechanism of component compositions. In a rapid growth, a plethora of different component models has been developed, using different technologies, having different aims, and using different principles. This has resulted in a number of models and technologies which have some similarities, but also principal differences, and in many cases unclear concepts. Component-based development has not succeeded in providing standard principles, as for example object-oriented development. In order to increase the understanding of the concepts, and to easier differentiate component models, this paper provides a Component Model Classification Framework which identifies and quantifies basic principles of component models. Further, the paper classifies a certain number of component models using this framework.

Tidskriftsartikel (refereegranskat)abstract
- In the last decade a large number of different software component models have been developed, with different aims and using different principles and technologies. This has resulted in a number of models which have many similarities, but also principal differences, and in many cases unclear concepts. Component-based development has not succeeded in providing standard principles, as has, for example, object-oriented development. In order to increase the understanding of the concepts, and to differentiate component models more easily, this paper identifies, discusses and characterises fundamental principles of component models, and provides a Component Model Classification Framework based on these principles. Further, the paper classifies a large number of component models using this framework.

Classification and Survey of Component Models
- 2010
-
Konferensbidrag (refereegranskat)abstract
- As component-based software engineering is growing and its usage expanding, more and more component models are developed. In this paper we present a survey of software component models in which models are described and classified respecting the classification framework for component models proposed by Crnković et. al. This framework specifies several groups of important principles and characteristics of component models: lifecycle, constructs, specification and management of extra-functional properties, and application domain. This paper gives examples three component models using the classification framework.

Knowledge Representation of Cyber-physical Systems for Monitoring Purpose

Konferensbidrag (refereegranskat)abstract
- Automated warehouses, as a form of cyber-physical systems (CPSs), require several components to work collaboratively to address the common business objectives of complex logistics systems. During the collaborative operations, a number of key performance indicators (KPI) can be monitored to understand the proficiency of the warehouse and control the operations and decisions. It is possible to drive and monitor these KPIs by looking at both the state of the warehouse components and the operations carried out by them. Therefore, it is necessary to represent this knowledge in an explicit and formally-specified data model and provide automated methods to derive the KPIs from the representation. In this paper, we implement a minimalistic data model for a subset of warehouse resources using linked data in order to monitor a few KPIs, namely sustainability, safety and performance. The applicability of the approach and the data model is illustrated through a use case. We demonstrate that it is possible to develop minimalistic data models through Open Services for Lifecycle Collaboration (OSLC) resource shapes which enables compatibility with the declarative and procedural knowledge of automated warehouse agents specified in Planning Domain Definition Language (PDDL).

Feasibility Assessment to Realise Vehicle Teleoperation using Cellular Networks
- 2016

Konferensbidrag (refereegranskat)abstract
- Future cellular networks (5G) will be used for a diversity of use cases. Transportation is one domain where cellular networks can play a significant role not only in connecting autonomous vehicles to other vehicles, infrastructures, and people, but also in realizing vehicle teleoperation i.e., vehicle driven by an operator from a distance. In this paper, we assess the feasibility of using a cellular network to realise vehicle teleoperation. We identify the network requirements for a teleoperated vehicle use case in an urban environment using a test setup of an LTE network and simulations. Testbed measurements reveal that teleoperation use cases can be supported even with less than excellent signal strength. Through simulation we show that the testbed can scale to cover greater distances and support teleoperation
