A comparative review of CASE shells: A preliminary framework and research outcomes

1993

Abstract Because of rigidity and weak support of the user's native methods and methodologies in existing CASE tools, there is a growing need for customizable CASE tools (CASE shells). The nature of CASE shells is different from ordinary CASE tools supporting a fixed set of methods. With CASE shells, organizations can define tools to support their own methods, instead of choosing a tool that supports them. Existing CASE shells have different features and architectural principles that make them appropriate for different tasks. Obviously, a framework for comparing them is needed. In this paper we develop one such framework. It takes into account different tasks in customization and the effecti…

Facing the Challenges of Multi-Channel Publishing in a Newspaper Company

2007

The study describes the transfer from paper-based publishing to multi-channel publishing in a Finnish newspaper publishing company and how this was experienced by the participants. The case analysis covers the news products of the company, the editorial processes, actors in the processes, the tools used to produce and manage news content, and the problems faced.

Analysis of pipeline accidents in the United States from 1968 to 2009

2014

Pipelines are responsible for the transportation of a significant portion of the U.S. energy supply. Unfortunately, pipeline failures are common and the consequences can be catastrophic. Drawing on data from the Pipeline and Hazardous Materials Safety Administration (PHMSA) that covers approximately 40,000 incidents from 1968 to 2009, this paper explores the trends, causes and consequences of natural gas and hazardous liquid pipeline accidents. The analysis indicates that fatalities and injuries from pipeline accidents are generally decreasing over time, while property damage and, in some cases, the numbers of incidents are increasing over time. In five of the ten cases considered in this p…

Realizing the Benefits from Enterprise Information Systems: A Sociomaterial Perspective

2013

AbstractDespite the worthwhile studies that have been conducted on the realization of benefits from Enterprise Information Systems (EISs), many organizations are not satisfied with the benefits they have gained. This work draws on the sociomaterial perspective and suggests that benefits can be realized when organizations are able to utilize their capabilities in order to exploit the technological possibilities of the EISs, in addition to their willingness to change their business routines. It suggests focusing on the unintended benefits that can emerge based on the organizational capabilities and the system possibilities. The main contribution from this conceptual work is to provide a discu…

Information Ecology as a holistic lens to understand ICTD initiatives

2016

Techno-centric initiatives to bridge the digital divide, such as One Laptop per Child (OLPC), has been criticized for not taking a holistic approach. This has led to limited success in areas such as providing quality education in developing countries. In this paper, we offer a premise for a holistic understanding by borrowing from the field of information ecology. To illustrate our premise, we applied the theoretical lens of information ecology to analyze a case study of Open Learning Exchange (OLE) which has been described as one of the few successes in implementing OLPC. Based on our analysis, we posit that information ecology is a suitable and appropriate lens to interpret and understand…

Understanding flow experience from users’ requirements

2015

This paper argues that the concept of flow can be useful in gaining a better understanding of information system users’ flow experience. This paper applies this concept in the requirements development phase of an Internet protocol television e-learning service development project. The findings show that flow experience can be visualised and measured, and that there are differences in how users see and perceive different features. Some features are driven by more experiential needs, whereas others are driven by more task-oriented goals. The findings indicate that the users’ perceived flow experiences can already be measured during the early phases of information systems IS development projec…

Heuristic-Based Shiftable Loads Optimal Management in Smart Micro-Grids

2015

In this paper, an optimal power dispatch problem on a 24-h basis for distribution systems with distributed energy resources (DER) also including directly controlled shiftable loads is presented. In the literature, the optimal energy management problems in smart grids (SGs) where such types of loads exist are formulated using integer or mixed integer variables. In this paper, a new formulation of shiftable loads is employed. Such formulation allows reduction in the number of optimization variables and the adoption of real valued optimization methods such as the one proposed in this paper. The method applied is a novel nature-inspired multiobjective optimization algorithm based on an original…

Engineering multi-agent systems: State of affairs and the road ahead

2019

International audience; The continuous integration of software-intensive systems together with the ever-increasing computing power offer a breeding ground for intelligent agents and multi-agent systems (MAS) more than ever before. Over the past two decades, a wide variety of languages, models, techniques and methodologies have been proposed to engineer agents and MAS. Despite this substantial body of knowledge and expertise, the systematic engineering of large-scale and open MAS still poses many challenges. Researchers and engineers still face fundamental questions regarding theories, architectures, languages, processes, and platforms for designing, implementing, running, maintaining, and e…
