Purpose – The paper seeks to outline an approach to a unified framework for understanding the concept of “information” in the physical, biological and human domains, and to see what links and interactions may be found between them. It also aims to re-examine the information science discipline, with a view to locating it in a larger context, so as to reflect on the possibility that information s...

In this paper we present a unified (probabilistic/possibilistic) model for resource-constrained project scheduling problem (RCPSP) with uncertain activity durations and a concept of a heuristic approach connected to the theoretical model. It is shown that the uncertainty management can be built into any heuristic algorithm developed to solve RCPSP with deterministic activity durations. The esse...

Purpose – The purpose of this study is to propose a knowledge-based mobile learning framework that integrates various types of museum-wide content, and supports ubiquitous, context-aware, personalized learning for museums. Design/methodology/approach – A unified knowledge base with multi-layer reusable content structures serves as the kernel component to integrate content from exhibitions for e...

Most of the existing clustering approaches concentrate on purely numerical or categorical data only, but not the both. In general, it is a nontrivial task to perform clustering on mixed data composed of numerical and categorical attributes because there exists an awkward gap between the similarity metrics for categorical and numerical data. This paper therefore presents a unified metric for dat...

Mathematics clearly plays an important role in scientific explanation. Debate continues, however, over the kind of that mathematics plays. I argue if pure mathematical explananda and physical are unified under a common explanation within science, then we have good reason to believe is explanatory its own right. The argument motivates search for new case study, which facts explanatorily unified....

This paper describes a product line use case modeling approach tailored towards organizations developing and maintaining extremely long lived software intensive systems. We refer to the approach as the PLUSS approach, Product Line Use case modeling for Systems and Software engineering. An industrial case study is presented where PLUSS is applied and evaluated in the target domain. Based on the ...

Data resource always plays the key role in modern enterprise applications. In the paper, we first give a detailed introduction of the existing data resource management approaches. Via the analysis and comparison of the existing apprpaches, a new unified framework for enterprise data resource management is proposed. The framework can encapsulate the heterogeneous data resources in a universal fo...

The quality of reusable elements must be rigorously monitored and guaranteed before they can be reused, this is known as Certification. High levels of certification of these elements generate trust and stimulate reuse. In this paper we describe the development of a tool based on quality oriented reuse strategies. To this end, we take as starting point an ontology that rigorously correlates the ...

This paper presents an augmented framework for analyzing Safety Critical Systems (SCSs) formally. Due to high risk of failure, development process of SCSs is required more attention. Model driven approaches are the one of ways to develop SCSs for accomplishing critical and complex function what SCSs are supposed to do. Two model driven approaches: Unified Modeling Language (UML) and Formal Meth...
