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…
Approccio olonico e sistema logistico-produttivo aziendale per i mercati del XXI secolo
2008
L’impresa industriale deve oggi far fronte a problematiche di rapidità ed efficacia di gestione dei processi, in presenza di frequenti disturbi e cambiamenti negli ordini di produzione. La gestione della Supply Chain (SCM) deve tenere conto di queste tendenze e trovare un paradigma organizzativo-gestionale in grado di fornire all’azienda la richiesta agilità e capacità di sincronizzazione del sistema logistico-produttivo con le nuove caratteristiche dei mercati. Ne i sistemi gerarchici ne quelli eterarchici sono in grado di soddisfare questi requisiti, mancando della necessaria agilità i primi e della capacità di garantire la prevedibilità necessaria alla sincronizzazione i secondi. L'idea …
Eco-efficiency assessment of olive farms in Andalusia
2012
Abstract Olive farming represents an important source of income and employment in the rural areas of Andalusia (Spain), which is the most important olive oil-producing region in the world. Unfortunately, it also exerts significant environmental pressures with regard to soil erosion, use of polluting inputs, excessive water consumption and biodiversity reduction. This paper uses Data Envelopment Analysis (DEA) techniques and pressure distance functions to contribute a farm-level assessment of the eco-efficiency of a sample of 292 Andalusian olive farmers. We distinguish between managerial eco-efficiency and program eco-efficiency, the latter being associated to the different natural conditio…
L'industrie microtechnique en Franche-Comté : un système productif complexe en cours de structuration
2007
This article reviews nearly four decades of change in the microtechnical industry of Franche-Comté. The case of the reconversion of French clockmakers, industrial districts in real crisis and territorial development around microtechnical industries, sheds invaluable light on the difficulties of restructuring an industry, despite the pressure of voluntary politics.
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…
