HOLONIC PRODUCTION SYSTEM TO OBTAIN FLEXIBILITY FOR CUSTOMER SATISFACTION
2008
The Holonic Production System (HPS) can be a valid choice to overcome the problems of traditional production sys-tems’ architectures, thanks to its capability to adapt and react to changes in the business environment whilst being able to maintain systemic synergies and coordination. The HPS is made of holons seen as functional production units which are simultaneously autonomous and cooperative. Although the holonic approach could represent a valid solution in order to pursue the necessary levels of agility of production systems, they have been scarcely implemented in practice and even less studied from a business studies perspective. The purpose of this discussion paper is to show the bene…
The holonic approach for flexible production: a theoretical framework
2011
This paper discusses the body of knowledge about Holonic Approach to theoretically demonstrate how Holonic Production System (HPS) can be a convincing choice to overcome the problems of traditional production systems? architectures. Today, enterprises are trying to find ways to manage the growing environmental complexity that is well described by Complex Systems Theory (CST). After the focus on the main problem regarding environmental complexity, the Holonic system and the Holonic Production System will be analyzed. The paper will focus the potential of HPS to adapt and react to changes in the business environment whilst being able to maintain systemic synergies and coordination through the…
Establishment of a commercial organic hopyard in a Mediterranean environment: Production attributes and their relationship with soil texture
2023
The cultivated hops are recently moving towards new growing areas in Southern Europe, boosted by the increasing number of craft breweries and by the higher vulnerability to climate change observed, for this crop, in the traditional growing regions. Despite this clear market and geographic trend, there is a lack of knowledge about pedoclimatic needs and agronomic performances of hops grown in the Mediterranean environment. Particularly, the agronomic potential of a new hopyard during its establishment period is poorly studied even in traditional growing zones. Moreover, a restricted number of plants were usually sampled to gather the few data available, thus leading to a probable overestimat…
Managing adoption by cultural development: Exploring the plant level effect of a ‘Company Specific Production System’ (XPS) in a Norwegian multinatio…
2020
Purpose: ‘Company Specific Production Systems’ (XPS) aim to adopt ‘best practice’ across plants within a company. A pertinent issue in the literature involves the constraints in the possibilities of realising such an adoption. This paper addresses to what extent and how a Norwegian multinational succeeded in adopting the XPS in its local plants. Design/methodology/approach: A Brazilian, Chinese and Norwegian plant of a Norwegian electro-chemical company were studied from 2017 to 2019. Our data consist of the results of the plant’s assessment performance program, combined with interviews and observations at different organizational levels. Findings: The MNC had largely managed to adopt the X…
Levels of dioxin-like polychlorinated biphenyls (DL-PCBs) and metals in European sea bass from fish farms in Italy
2012
The study evaluated the levels of dioxin-like polychlorinated biphenyls (DL-PCBs) and metals in the fillet of medium (468 ± 92 g) and large (708 ± 135 g) European sea bass (Dicentrarchus labrax) from 11 Italian fish farms using different rearing systems. DL-PCB contamination was higher in fish grown in extensive coastal lagoons compared with intensive inland basins and intensive sea cages (28.5 vs. 9.13 and 13.1 pg Toxic Equivalents (TEQ)/g fat; P < 0.001). Copper concentrations were lower (0.810 vs. 0.993 and 1.071 mg/kg fw) and mercury was higher (0.025 vs. 0.006 and 0.003 mg/kg fw) (P < 0.001) in sea bass from extensive farms than from intensively farmed fish in inland or sea cage system…

Solving the Problems of Inspection Planning under Parametric Uncertainty of Underlying Models
2013
Certain fatigued structures must be inspected in order to detect fatigue damages that would otherwise not be apparent. A technique for obtaining optimal inspection strategies is proposed for situations where it is difficult to quantify the costs associated with inspections and undetected failure. For fatigued structures for which failures (fatigue damages) are only detected at the time of inspection, it is important to be able to determine the optimal times of inspection. Fewer inspections will lead to lower fatigue reliability of the structure upon demand, and frequent inspection will lead to higher cost. When there is a fatigue reliability requirement, the problem is usually to develop an…
Not so different altogether: Putting Lean and sociotechnical design into practice in a process industry
2021
Purpose: The shop-floor organization under lean production (LP) has been hotly debated for about three decades. As this organization concept leaves considerable room for interpretation, the content of lean-inspired changes can vary widely. This paper pleads for a contingency view of how LP is implemented and how the outcomes of lean-inspired changes rely on users’ interpretations of the concept in particular production contexts.Design/methodology/approach: A case study was conducted in two large Norwegian chemical plants. Data from the observations and interviews were supplemented by interviews with top managers in 2017 and 2018. The first author also followed a management audit in one plan…
Game Theory with Engineering Applications
2016
Engineering systems are highly distributed collective systems—decisions, information, and objectives are distributed throughout—that have humans in the loop, and thus decisions may be influenced by socioeconomic factors. Engineering systems emphasize the potential of control and games beyond traditional applications. Game theory can be used to design incentives to obtain socially desirable behaviors on the part of the players, for example, a change in the consumption patterns on the part of the “prosumers” (producers-consumers) or better redistribution of traffic. This unique book addresses the foundations of game theory, with an emphasis on the physical intuition behind the concepts, an an…
