Procedure Model for the Analysis and Design of Reporting Systems – A Case Study in Conceptual Modelling

A structured conceptual design of reporting systems is a crucial task that has to precede implementation and monitoring. A basic challenge can be seen in information requirements engineering. On the one hand, users need certain information to successfully accomplish their tasks. On the other hand, it has to be avoided to supply them with too much and potentially irrelevant information. Information requirements engineering has to support the conceptual specification of information requirements. Thus, there is need for conceptual languages and appropriate procedure models. We propose a procedure model for the analysis and conceptual design of reporting systems as well as a conceptual modelling language that can be used for both as-is analysis and to-be modelling. It has been developed in an iterative approach based on multiple case studies. Due to the fact that different projects and different basic conditions require the use of different approaches of information requirements engineering, within the procedure model different approaches can be used. In this paper we introduce both procedure model and conceptual modelling language and present findings of a case study in which they were used

Considering Manufacturing in Functional Modelling - Case Study on Combination of Simulation-Driven Design with Design-for-Manufacture

In engineering design, function fulfilment is the raison d\u27être of a product. However, economic boundary conditions have to be taken into consideration as well to enable marketability of the product. In this paper, a case study is presented, where function-based engineering using the Simulation-Driven Design is linked with Design-for-Manufacture as an example for economic design through qualitative modelling. The qualitative modelling with the Contact and Channel Approach aims to support the integrated consideration of functional requirements and manufacturing boundary conditions. The linked approaches are applied in the development of a test rig for hammer drills. It shows how Design-for-Manufacture can be considered early in conceptual decisions in embodiment design by separating functional embodiment and residual structure through qualitative modelling. The freeze-unfreeze strategy is presented as a possibility to identify potential for Design-for-Manufacture to meet economic boundary conditions in conceptual design without reducing the functionality of the system. Further research possibilities regarding qualitative modelling to support functional and economic design are uncovered

A Model-Based Approach Towards the Conceptualization of Digital Twins: The Case of the EU-Project COGITO

In agile business ecosystems, digitalization is a key enabler for agility and flexibility. However, digital transformation is often challenging for instance due to unclear definitions and a lack of problem understanding. In this work this complexity is addressed with a model-based approach for conceptualizing digitalization and related meta modelling activities to enable the conceptual integration of diverse concepts. Existing modelling approaches – BPMN and ArchiMate – are leveraged with domain specific considerations that are relevant for the digitalization. The construction use case from the European project COGITO serves as a foundation for ideation and first requirements engineering. Physical experiments in the OMiLAB Innovation Environment are used as an experimental method towards identifying relevant digital twinning concepts, while modelling methods can be seen as an integration platform for physical and digital elements. Key digitalization aspects towards digital twinning are discussed and conceptualized in a meta model

24th International Conference on Information Modelling and Knowledge Bases

In the last three decades information modelling and knowledge bases have become essentially important subjects not only in academic communities related to information systems and computer science but also in the business area where information technology is applied. The series of European – Japanese Conference on Information Modelling and Knowledge Bases (EJC) originally started as a co-operation initiative between Japan and Finland in 1982. The practical operations were then organised by professor Ohsuga in Japan and professors Hannu Kangassalo and Hannu Jaakkola in Finland (Nordic countries). Geographical scope has expanded to cover Europe and also other countries. Workshop characteristic - discussion, enough time for presentations and limited number of participants (50) / papers (30) - is typical for the conference. Suggested topics include, but are not limited to: 1. Conceptual modelling: Modelling and specification languages; Domain-specific conceptual modelling; Concepts, concept theories and ontologies; Conceptual modelling of large and heterogeneous systems; Conceptual modelling of spatial, temporal and biological data; Methods for developing, validating and communicating conceptual models. 2.

Overall we received 56 submissions. After careful evaluation, 16 papers have been selected as long paper, 17 papers as short papers, 5 papers as position papers, and 3 papers for presentation of perspective challenges. We thank all colleagues for their support of this issue of the EJC conference, especially the program committee, the organising committee, and the programme coordination team. The long and the short papers presented in the conference are revised after the conference and published in the Series of “Frontiers in Artificial Intelligence” by IOS Press (Amsterdam). The books “Information Modelling and Knowledge Bases” are edited by the Editing Committee of the conference. We believe that the conference will be productive and fruitful in the advance of research and application of information modelling and knowledge bases. Bernhard Thalheim Hannu Jaakkola Yasushi Kiyok

Using OWL-VisMod through a decision-making process for reusing OWL ontologies

[EN] Knowledge representation (KR) can be defined as a set of ontological commitments, provided with the capabilities of performing inference. The knowledge can be represented using an ontology, which provides a shared insight into a certain domain. The use of ontologies to represent knowledge also allows interoperation among knowledge-based systems. The process of building ontologies can be tedious and sometimes exhaustive. A possible solution in order to avoid this problem would be to reuse the ontologies previously created by others. This paper describes a case study of reusability using OWL-VisMod, a tool designed for developing ontological engineering based on visual conceptual modelling for OWL ontologies. A workflow performed with OWL-VisMod is described; including a decision-making process in order to decide whether or not it could be desirable to reuse an ontology, according to the requirements of a certain project

Requirements modelling and formal analysis using graph operations

The increasing complexity of enterprise systems requires a more advanced analysis of the representation of services expected than is currently possible. Consequently, the specification stage, which could be facilitated by formal verification, becomes very important to the system life-cycle. This paper presents a formal modelling approach, which may be used in order to better represent the reality of the system and to verify the awaited or existing system’s properties, taking into account the environmental characteristics. For that, we firstly propose a formalization process based upon properties specification, and secondly we use Conceptual Graphs operations to develop reasoning mechanisms of verifying requirements statements. The graphic visualization of these reasoning enables us to correctly capture the system specifications by making it easier to determine if desired properties hold. It is applied to the field of Enterprise modelling

Using structured analysis and design technique (SADT) for simulation conceptual modelling

Conceptual Modelling (CM) has received little attention in the area of Modelling and Simulation (M&S) and more specifically in Discrete Event Simulation (DES). It is widely agreed that CM is least understood despite its importance. This is however, not the case in other fields of science and engineering (especially, computer science, systems engineering and software engineering). In Computer Science (CS) alone, CM has been extensively used for requirements specification and some well-established methods are in practice. The aim of the thesis is to propose a CM framework based on the principles of software engineering and CS. The development of the framework is adapted from a well-known software engineering method called Structured Analysis and Design Technique (SADT), hence it is called SADT CM. It is argued that by adapting approaches from CS, similar benefits can be achieved in terms of formality, understanding, communication and quality. A comprehensive cross-disciplinary review of CM in CS and M&S is undertaken, which highlights the dearth of standards within M&S CM when compared to CS. Three important sub-fields of CS are considered for this purpose namely, information systems, databases and software engineering. The review identifies two potential methods that could be adopted for developing a M&S CM framework. The first method called PREView was found unsuitable for M&S CM in DES domain. Hence, the thesis concentrates on developing the framework based on SADT. The SADT CM framework is evaluated on three-in depth test cases that investigate the feasibility of the approach. The study also contributes to the literature by conducting a usability test of the CM framework in an experimental setting. A comprehensive user-guide has also been developed as part of the research for users to follow the framewor

An integrated product and process information modelling system for on-site construction

The inadequate infrastructure that exists for seamless project team communications has its roots in the problems arising from fragmentation, and the lack of effective co-ordination between stages of the construction process. The use of disparate computer-aided engineering (CAE) systems by most disciplines is one of the enduring legacies of this problem and makes information exchange between construction team members difficult and, in some cases, impossible. The importance of integrating modelling techniques with a view to creating an integrated product and process model that is applicable to all stages of a construction project's life cycle, is being recognised by the Construction Industry. However, improved methods are still needed to assist the developer in the definition of information model structures, and current modelling methods and standards are only able to provide limited assistance at various stages of the information modelling process. This research investigates the role of system integration by reviewing product and process information models, current modelling practices and modelling standards in the construction industry, and draws conclusions with similar practices from other industries, both in terms of product and process representation, and model content. It further reviews various application development tools and information system requirements to support a suitable integrated information structure, for developing an integrated product and process model for design and construction, based on concurrent engineering principles. The functional and information perspectives of the integrated model, which were represented using IDEFO and the unified modelling language (UML), provided the basis for developing a prototype hyper-integrated product and process information modelling system (HIPPY). Details of the integrated conceptual model's implementation, practical application of the prototype system, using house-building as an example, and evaluation by industry practitioners are also presented. It is concluded that the effective integration of product and process information models is a key component of the implementation of concurrent engineering in construction, and is a vital step towards providing richer information representation, better efficiency, and the flexibility to support life cycle information management during the construction stage of small to medium sized-building projects
