An integrated structural framework to cost-based FMECA: the priority cost FMECA
No full textThe Failure Mode, Effects and Criticality Analysis methodology (FMECA) is a widely recognised tool for the study and reliability analysis of a design or process. Many authors in the field have emphasised the usefulness of this particular method as well as its limitations. In particular, there are two main criticisms regarding the Risk Priority Number method of calculation and the extreme difficulty in considering the variable of the corrective action cost in the analysis. The main scope of this work is to present a new integrated approach, named Priority Cost FMECA (PC-FMECA), in order to exceed these limits. Making reference to a paper by Braglia [1], this study proposes a method which allows for the calculation of a new RPN and the introduction of the concept of Profitability taking into consideration the corrective action cost. The study is divided in three fundamental phases: critical analysis of the FMECA model, proposal and development of the PC-FMECA and presentation of an implemented case-study in the automotive field
METODI GESTIONALI Progettare e migliorare le organizzazioni
No full textLe competenze tecniche sono la base. Ma la complessità del mondo impone la necessità di avere anche competenze gestionali, altrimenti concetti come sostenibilità, innovazione, digitalizzazione rimangono solo parole alla moda. Alle organizzazioni (pubbliche, private, profit e no-profit) servono persone e metodi per ottenere risultati concreti attraverso una corretta progettazione e tenuta sotto controllo della propria attività. Il testo illustra strumenti applicativi propri dell’ingegneria gestionale utili per rispondere ogni giorno alle sfide presenti e future.
Non sono concetti spettacolari che contraddistinguono le organizzazioni migliori. È semplicemente il modo intransigente di applicare strumenti e metodi già noti
Supply chain and quality management: the definition of a standard to implement a process management system in a supply chain
No full textPurpose – The aim of this paper is to present the results of a research for developing a
standard to implement a process management system in a whole supply chain.
Design/methodology/approach – To gain the aim, the research has been developed in
two parts. The quality management part has the objective to select the reference model
to develop the standard. The supply chain management part has, instead, the objective to
select the drivers and the main processes that the standard have to manage. The
evaluation of the results of these parts has permitted to define the proposed standard.
Findings – A modified interpretation of ISO 9001:2000 norm is proposed permitting (i)
to improve the ISO 9001 standard to the general requirements for a whole process
approach, (ii) to extend and to apply the ISO 9001 concepts, that address quality aspects
within a single organization, to a whole supply chain and (iii) to facilitate the
introduction of the modern principles and techniques of Supply Chain Management.
Finally, the standard to implement a management system for a whole supply chain is
introduced through the identification of the main supply chain processes and drivers.
Research limitations/implications – The standard proposed is a specific for a generic
supply chain. Further studies will be necessary to (i) customize the standard to
appropriate productive sectors and (ii) validate the appropriate content through real
applications.
Practical implications – The standard proposed is a guide line to implement a
management system in a supply chain and, for this aim, it can be applied in a generic
supply chain.
◌ீˋ
Originality/value – The standard proposed is an original tool to improve the
collaboration and processes integration between the partners into a supply chain and this
scope can be the actual value of the presented methodology

Process-based management: a structured approach to provide the best answers to the ISO 9001 requirements
No full textPurpose: To provide a structured method to apply process management approach following ISO 9001:2000 requirements, comma 4.1.
Design/methodology/approach: The content of this article is focused on the detailed analysis of the fourth comma of the 2000 edition of norm ISO 9001, and it presents an articulated procedure which can be undertaken by any organization in order to give the best answers to the requirements therein.
Findings: The method described consists in eight steps, with a top-down approach going from the definition of the macro-processes of the organization to the definition of the single stages which constitute the activities. An approach to implement quality objectives deployment is implemented. In order to better explain the methodology, a case study is used.
What is original/value of paper: Indeed, it is thought that the content of the fourth comma of ISO 9001, and in particular of paragraph 4.1, represents one of the most important innovations brought in by the new edition which nevertheless, since this paragraph contains requisites oriented more towards method and approach mentality to the quality system and less towards detail and strictly operational prescriptions, has been poorly and erroneously understood, or even deliberately not taken into account. The proposed methodology rapresent an original guide line to implement process management approach
Scrap Value Stream Mapping (S-VSM): a new approach to improve the Supply Scrap Management Process
No full textIn this work, an innovative methodology to improve the Supply Scrap Management Process (SSMP), based on Value Stream Mapping (VSM), is presented. VSM is one of the best tools to map a process and eliminate its critical issues, that produces good results if applied to production processes, but can be ineffective for management processes as the SSMP. Therefore, the main objective of this work is to overcome this limitation. The proposed approach taking the name Scrap Value Stream Mapping (S-VSM) and integrates concepts from VSM and other Lean Production (LP) and World Class Manufacturing tools. It is structured in five steps. The definition of the process borders and the identification of categories of loss through the first four steps of Cost Deployment is the first step. Then, the SSMP is subdivided in its Accounting and Physical Streams and the current state is drawn. Next, wastes and critical issues are analyzed and their root causes are determined by using some of LP tools. In step four, improvements are proposed and the future state is drawn. Furthermore, potential savings, in terms of €, are estimated. In the last step, a methodology to monitor the effects of implemented improvements is defined. A case study taken from the application of the S-VSM within automotive company is presented
