A stochastic method for robustness analysis in sorting problems
2009
ELECTRE TRI is a multiple criteria decision aiding sorting method with a history of successful real-life applications. In ELECTRE TRI, values for certain parameters have to be provided. We propose a new method, SMAA-TRI, that is based on stochastic multicriteria acceptability analysis (SMAA), for analyzing the stability of such parameters. The stability analysis can be used for deriving robust conclusions. SMAA-TRI allows ELECTRE TRI to be used with uncertain, arbitrarily distributed values for weights, the lambda cutting level, and profiles. The method consists of analyzing finite spaces of arbitrarily distributed parameter values. Monte Carlo simulation is applied in this in order to desc…
Information systems and strategy design
1999
Abstract Strategic thinking forms a wide-ranking, complex area of thought. It also seems to be an extremely interesting and important field in both management practice and literature. Recently, the areas that the different functions (like accounting, marketing, production and information systems) of firm and strategic thinking have in common have been lively discussed. In this paper, the applicability of information systems thinking to strategic thinking is outlined. For that purpose, three modes of strategy-making are explicated: strategy-making as management process, as game-playing and as leadership. In each of these three modes, the strategy design phase and especially the essentials of…
Long term capacity decisions in uncertain markets for advanced manufacturing systems incorporating scope economies
2002
Abstract By examining the literature in the field of manufacturing flexibility many researchers have located several form of flexibility by distinguishing them into strategic and operational flexibility forms. Furthermore, many measures and design methods have been proposed for flexible manufacturing systems. Surely scope economies are one of the most important strategic form of flexibility in manufacturing systems and their strategic impact has been acknowledged by the very beginning of the flexible manufacturing era. However, despite several researches are available to address scope economies measurement and design methodologies, very few researches investigate their economic convenience …
A Genre-Based Method for Information Systems Planning
2001
Currently, corporations implement diversified computer-based information systems (IS). These include organization-scale solutions such as enterprise resource planning systems, inter-, extra-, and intranet applications, product data management, and enterprise document management systems. At the same time, the end user is ever more capable of rapidly developing and tailoring small-scale applications for groups, organizational units, and personal purposes independently (Grover, Teng, and Fiedler, 1998). Furthermore, corporations are investing in information technology infrastructures that take full advantage of global networking and business process re-engineering (Broadbent and Weill, 1997; G…

Measuring diversity. A review and an empirical analysis
2021
Abstract Maximum diversity problems arise in many practical settings from facility location to social networks, and constitute an important class of NP-hard problems in combinatorial optimization. There has been a growing interest in these problems in recent years, and different mathematical programming models have been proposed to capture the notion of diversity. They basically consist of selecting a subset of elements of a given set in such a way that a measure based on their pairwise distances is maximized to achieve dispersion or representativeness. In this paper, we perform an exhaustive comparison of four mathematical models to achieve diversity over the public domain library MDPLIB, …
Two-dimensional filters for structured text
1997
The paper introduces a method for defining filters for structured text. In the method, the text structure is originally defined by a grammar consisting of a set of productions. To describe the information interests, a two-dimensional template is first created interactively from the grammar to show the structure of a set of textual elements, at a chosen level of detail. The template depicts the hierarchical structure of the elements and indicates also optionality, alternatives, and iteration in the structure. Then, the template is filled by constraints and annotations. The constraints allow giving conditions to the content of parts, to the position of parts in an ordered set of parts, and to…
Interactions between contingency, organizational IT factors, and ERP success
2009
PurposeThe purpose of this paper is to examine the impact of some organizational information technology (IT) factors (i.e. IT assets, employees' IT skills, IT resources, and satisfaction with legacy IT systems) and their interacting effects with two contingency factors (i.e. organization's size and structure) on enterprise resource planning (ERP) system success.Design/methodology/approachSurveys were conducted in two European countries. Respondents came from diverse, private, and industrial organizations. Relevant hypotheses were developed and tested using a structural equation modeling technique.FindingsThe analysis supported – partially or fully – six of the eight hypotheses formulated. F…
Public Sector Applications of the System Dynamics Approach
2010
The article discusses various reports published within the issue, including one by Carmine Bianchi on understanding public sector from different levels and perspectives, one by Mauro Lo Tennero on the aspiration and structure of Sicily to enforce public policy, and one by Nuno Videira and colleagues on the use of group model building in the public sector to concur sustainable policies.
