Business Process-oriented design of Enterprise Resource Planning (ERP) systems for small and medium enterprises
2006
In the last few years, many organizations have used business process modelling as an effective tool for managing organizational changes. However, process modelling has rarely been exploited for supporting the entire business process management life cycle. This includes the design of business processes as well as their implementation and control. The adoption and implementation of Enterprise Resource Planning (ERP) systems is a crucial issue if referred to small and medium-sized enterprises. The main problem is that the cost of implementation of ERP, intended as the process of customization of the ERP system towards the actual enterprise business processes, overtakes the cost of ERP acquisit…
Experienced knowledge for the description of maintenance packages
2015
International audience; The presented work is included in the research theme that specifies some means of capitalization andexploitation of knowledge from experience feedback processes in the context of industrial maintenancemanagement. Our research on it is a more precise definition of the proposed project, built with a problemasking how to handle the management of repair packages. Upstream, the knowledge of various expertsare materialized in the form of expert reports. Downstream maintenance wants to quickly repair productsbased on symptoms or change parts in advance. For this, we propose a methodology by analysing thefeedback to improve the response time for maintenance services. This is…
Strengthening of steel-reinforced concrete structural elements by externally bonded FRP sheets and evaluation of their load carrying capacity
2014
Abstract The paper proposes a preliminary design tool for reinforced concrete (RC) elements strengthened by fiber-reinforced-polymer (FRP) sheets to be used in civil engineering applications and in particular in medical buildings. The design strategy is based on limit analysis theory and utilizes a numerical procedure which provides a direct method to determine peak load, failure mode and critical zones of the structural elements of interest.
Small world theory and the World Wide Web: linking small world properties and website centrality
2016
This qualitative paper aims to point out the incidence of small world characteristics in the World Wide Web. To this end, some theoretical implications of small world theory (SWT) are verified using information from focus groups and in-depth interviews administered to experts and users of the World Wide Web. The purpose of this study is to investigate whether it is possible to apply small world properties to online social networks while pointing out the key variables of website centrality in that context. Building on this, the paper traces possible contributions for better management of the World Wide Web in terms of the professional use of social media to facilitate information or product …
A strategic framework for firm networks in manufacturing industry: An empirical survey
2009
Firm networking is becoming more and more the most important competitive strength in nowadays competitive environment. Such an evidence is partially neglected by the classical strategic analysis of firms competitiveness which mainly looks at the firm strength and weakness not in relationship with its capacity to build competitive networks. For such a reason, in the last years, many theoretical approaches have stressed the importance of networks to gain competitive advantage. In this paper, the most significant theories on firm networking are reviewed and an innovative strategic framework that mainly underlies at firm networks organisation is proposed. Very briefly, it is argued that network…
High Level Planning of Reconfigurable Enterprises: a Game Theoretic Approach
2006
Reconfigurable Enterprises (REs) represent production networks made of different and geographically dispersed plants that, in case of unpredictable market changes, can be reconfigured in order to gather a specific production objective. However, REs effectiveness and efficiency depend on the extent to which global performance is obtained. Basically two approaches are available to reach coordination: centralised or decentralised planning tools. In this paper, the authors propose a novel cooperative game theoretical approach for distributed production planning at high level of a RE; the proposed approach has been benchmarked in front of both a distributed one, based on negotiation, and a centr…
Distributed intelligent control of exceptions in reconfigurable manufacturing systems
2003
In order to react to the continuous and unpredictable changes in product demand, in product variety, and in process technologies, reconfigurable manufacturing systems allow quick adjustment of production capacity and functionality by rearranging or changing their modular components. In this kind of system, operation management issues, such as exception handling policies, become more complex since correct reconfiguration strategies have to be selected. This paper explores the potential of the reconfigurability feature to be a basis for the development of new strategies to handle out-of-the-ordinary events in the production process; in particular, maintaining production flow when machine brea…
Decoding the Japanese Lean Production System according to a Viable Systems Perspective
2012
The increase in the complexity and variability of the business environment, due to constant and rapid changes in markets, calls for more flexible and effective production systems. Of the most valuable production systems, the Japanese lean production system (LPS) is the best known and studied, but is still not the most widely applied with success outside Japan. The reason for the low level of success of lean production outside its native country is the lack of understanding of the strong interactions which hold between enterprises and business systems. In order to fill this gap in our knowledge, we investigate the systemic interactions according to the Viable System View. To develop our anal…
Reconfigurable control of robotized manufacturing cells
2007
This paper investigates the field of manufacturing system control. The addressed subject is indeed very fascinating, due to the importance that it has reached in the last decades both at research and industrial level. On the other hand, it seems to the author that most of the complexity intrinsic to the subject itself relies on the different meanings or levels of abstraction that both the terms ''manufacturing system'' and ''control'' may symbolize. The presented research aims to face the topic in a concrete fashion, i.e., by developing a control software system for a specific, although easy to be generalized, robotized manufacturing cell. Two different development methodologies, from the c…
