Do top- and mid-level managers view Enterprise Resource Planning (ERP) systems success measures differently?
2006
We investigated ERP systems success measurement from the perspectives of top- and mid-level managers. Using surveys in two small Northern European countries, we aimed to determine whether differences exist between the two groups. Our results showed that there are no significant statistical differences between the two groups. The implications of the findings for both practice and research are outlined.
Automated vehicles' work planning in flexible manufacturing systems
2006
The problem of rules setting in coordination of automated vehicles access to shared system resources (sections of their transportation paths) which assure a deadlock free and starvation free flow of the executed processes belongs to NP-hard problems. Assuming that there are local (controlling access to shared resources) rules of priority dispatching, the problem deals with setting conditions sufficient for a pair (initial state, set of priority dispatching rules). The assumed knowledge base way of specifying a transportation subsystem leads to solving a logic-algebraic method decision problem. In this regard, the working knowledge representation synthesis method constitutes a significant co…
Recruitment, knowledge integration and modes of innovation
2015
Abstract This paper investigates how the strength and intrinsic characteristics of firms’ knowledge bases and processing routines have evolved with the past inflow of employees. The empirical analysis is based on linked public register and innovation survey data for Norway. It finds that recruitment from universities, research institutes and higher education institutions has increased the capacity of firms to generate technical inventions. Yet, the organizational knowledge bases and processing routines on which commercial innovation output depends have been strengthened only by the recruitment that has occurred from related industries. Implications for research, management and policy are dr…
An affine scaling method using a class of differential barrier functions: primal approach
2020
International audience; In this paper we propose a family of affine scaling interior point algorithms, called galpv4, using a primal approach, based on a large class of differential barrier functions. We show that these algorithms are in fact an extension and generalization of the classical affine scaling algorithm based on the well-known log barrier function. After carrying out a complete convergence analysis, we select some of these algorithms for comparison with the classical affine scaling algorithm, performed with the help of the familiar Netlib test set.
Managing asymmetry in franchise contracts: transparency as the overriding rule
2012
PurposeThe aim of this article is to provide solutions to protect the weaker party in management and distribution contracts, especially in the field of franchising.Design/methodology/ approachThe paper is based on a review of literature, legislation and practices concerning management and franchise contracts. The regulation of this field at a national level consists of laws that are both private and mandatory in nature. Certain questions are raised concerning the obligatory nature of regulations when applied to the management of international franchise contracts.FindingsThis article studies the question of whether the imperative application of laws to international contract management is ap…
The minimal cost maximum matching of a graph (supplementary remarks)
1971
In addition to the preceding paper, it will be shown that (1) the matching problem is closely related to the linear assignment problem and how (2) this property can be taken advantage of for solving the matching problem.
Recent Developments in our Approach to Multiple-Criteria Decision Making
1984
Approximately ten years ago we began a study of multiple criteria decision making at the European Insti tute for Advanced Studies in Management in Brussels. The project started as a way of finding a multiple objective linear programming method that would work better than those tested by Wallenius (1975). We did a substantial amount of work on the problem and came up with such a method (Zionts and Wallenius, 1976). Wallenius’ (1975) thesis, one of the first outputs of that project, comprises a rather significant piece of research in the multiple criteria area. Since that time our work has continued. We have worked together on a great deal of it; some of it has involved students and other fac…
Relating examinations to the Common European Framework: a manual
2005
This article deals with the linking of examinations to the Common European Framework of Reference (CEFR). Following the rapid adoption of the CEFR by the Council of Europe and the European Union as well as many national and local actors, there have been calls for guidance on how examinations could be made more transparent by means of the CEFR, especially by using its calibrated scales as a tool. The Council of Europe has recently produced a preliminary pilot Manual, which presents a procedure for doing this. The article describes the political and educational context of this work and presents the main procedures proposed in the Manual. Since the Manual is a preliminary document for discuss…
Strategies for Progress: Looking for Firm Ground
2015
Over the last thirty years, there have been various and increasing efforts made to establish effective and consistent public service interpreting and translation. Good progress has been made but there are impasses. This paper attempts to stand back and look objectively at where, and more importantly how, we might proceed from here. This could be said to be a turning point for legal interpreting for two reasons. Firstly, enough time has elapsed for us to copy our scientific colleagues, who view the process of exploring and eliminating unsatisfactory approaches overtly, so that what does not work is recognised and discarded. Secondly, this process of exploration has enabled us to clarify and …
Spelling out consequences : conditional constructions as a means to resist proposals in organisational planning process
2016
Organisational planning processes often materialise as a series of meetings, where the future of the organisation is jointly discussed and negotiated as a part of local decision-making sequences. Using conversation and discourse analytical approaches, this article investigates how proposals concerning the future can also be resisted by employing a specific device, a conditional construction ( if X, then Y). The data for the study originate from a city organisation, whose customer services are being developed. The results show how the conditional constructions work in two interrelated ways. First, by introducing a problematic hypothetical situation, they outline the undesirable consequences…
