Industrial workstations design: A real case study
No full textThis research work advances the effective design of the most critical workstations belonging to a real industrial plant. To this end, the authors propose an approach based on the integration of Modelling & Simulation (M&S) tools, several ergonomic standards and the best known work measurement tools. The effective design of the workstations is achieved by using the simulation model for comparing workstations' alternative configurations. The comparison is based on ergonomic and time indexes related to the ergonomic standards and the work measurement tools. Such comparison allows to choose the workstations' final configurations.

Ethics of restoration and conservation science: the completion and reuse of the former Mother Church in Santa Margherita di Belice (Sicily) / Ética de la restauración y ciencia de la conservación: la integración y la reutilización de la antigua Iglesia Matriz de Santa Margherita di Belice (Sicilia)
No full textRestaurare l’architettura significa conservare la sua essenza autentica e le stratificazioni storiche, rispettare il criterio della distinguibilità e attualizzare le funzioni che racchiude. Questo moderno indirizzo culturale e metodologico ha sostanziato il progetto di restauro e di rifunzionalizzazione della ex chiesa madre di Santa Margherita di Belice, in Sicilia, che oggi ospita il “Museo della Memoria”.
L’istinto progettuale conservativo si è manifestato fin dalle prime ipotesi d’intervento, quando è stata rigettata la possibilità di riproporre “nuovamente” le masse murarie del monumento, sconquassate da un violento terremoto nel 1968. Si è scelto, infatti, d’attuare un’operazione raffinata e di grande spessore culturale, perseguendo la via della rigorosa conservazione del frammento architettonico superstite, autentico, e la ridefinizione del volume della fabbrica attraverso un nuovo involucro strutturale.
Dopo aver rigettato l’idea di riportare il testo alla sua forma primigenia facendo ricorso alla filologia, si è preferito attuare un protocollo d’indagini scientifiche (curate dal Laboratorio d’indagini e Restauro dei Beni Architettonici dell’Università degli Studi di Palermo) a sostegno di un vigoroso programma conservativo della materia autentica e realizzare, con linguaggio, materiali e tecniche costruttive attuali, la nuova struttura, pur rispettando le matrici ed i moduli geometrici che avevano condotto all’edificazione della chiesa distrutta dal sisma. La nuova copertura consente alla luce naturale di accedere all’interno della grande aula, penetrando lo schermo di doghe lignee che ripropone idealmente la sagoma della volta distrutta. Estese aperture vetrate spalancano suggestive viste prospettiche sulle pareti decorate a stucco, visibili anche dagli spazi urbani esterni.
Il contributo intende presentare una sintesi degli esiti delle indagini diagnostiche strumentali di tipo non distruttivo e minimamente invasivo; inoltre, alcuni momenti del cantiere di restauro saranno ripercorsi attraverso le immagini degli interventi in corso d’opera.A Restoration has to preserve the authentic character of historic architecture and its meaningful stratifications; it must make the new structure distinguishable and suggest a compatible use. This cultural position sustained the intervention on the remains of the former Mother church of Santa Margherita di Belice in Sicily, now reused as “Museum of Memory”.
The philological reconstruction of the collapsed parts in 1968 was discarded since the restoration project was focused on the conservation of the authentic fragment and the redefinition of the architectural shapes with new structural components. A scientific campaign of diagnostic tests (performed by LIRBA, University of Palermo) supported the consolidation of the stucco plasters, and the reintegrated parts were made with modern materials and techniques, as the sign of our culture. The new roof allows light to enter the interior of the former church and cross the screen of wooden slats that ideally proposes the shape of the collapsed vault.
The paper is intended to introduce a summary of the reflections and choices, and present the final result of the restoration and reuse

Preservation of the remains and contemporary grafts in the former Mother Church of Santa Margherita di Belice in Sicily: ethics of restoration, conservation science and reuse
No full textUn restauro di qualità deve rispettare il carattere dell’architettura storica e le stratificazioni, rendere distinguibili le parti aggiunte e suggerire l’uso compatibile. Questo moderno indirizzo culturale e metodologico ha guidato l’intervento sui resti della ex chiesa madre di Santa Margherita di Belice, in Sicilia, ora destinata ad ospitare il “Museo della Memoria”. La ricostruzione filologica delle parti crollate nel 1968 è stata scartata, indirizzando il cantiere verso la rigorosa conservazione dell’autentico frammento architettonico e la ridefinizione del volume perduto mediante un nuovo involucro contemporaneo. Una campagna d’indagini diagnostiche (condotte dal Lirba, Università di Palermo) ha supportato un poderoso programma conservativo delle superfici di finitura a stucco; inoltre le strutture innestate alla preesistenza sono state realizzate con materiali e tecniche attuali. La nuova copertura permette alla luce di entrare all’interno della ex chiesa e attraversare lo schermo di listelli lignei che ripropone idealmente la sagoma della volta crollata. Il contributo intende presentare sinteticamente i risultati delle indagini e le fasi salienti del cantiere di restauro.A restoration must preserve the authentic character of architecture and its historic stratifications, differentiate the new structure and suggest a compatible reuse. This current cultural orientation supported the intervention on the remains of the former mother church of Santa Margherita di Belice in Sicily, now reused as a “Museum of Memory”. In fact, the philological reconstruction of the collapsed parts in 1968 was discarded, and targets of the restoration were the scientific conservation of the authentic fragment and the redefinition of the architectural shapes with new contemporary structural components. A scientific campaign of diagnostic tests (performed by LIRBA, University of Palermo) supported the consolidation of stucco finishes, while the reintegrated parts were made with modern materials and techniques. The new roof allows light to enter the interior of the former church and cross the screen of wooden slats that ideally proposes the shape of the collapsed vault. The paper is intended to present a summary of the survey results and the most important phases of the restoration site
Modelling, simulation and ergonomic standards as support tools for a workstation design in manufacturing system
No full textIt is the intent of the work to achieve the ergonomic effective design for a workstation belonging to a manufacturing system operating in the field of mechanical parts production. To this end, the NIOSH 81, NIOSH 91, Burandt Schultetus and OWAS analysis are accomplished for developing an improved workstation configuration in terms of interaction between humans and their working environment. Moreover the authors adopt an advanced approach based on Modeling & Simulation (M&S) in order to implement a three dimensional environment for recreating with satisfactory accuracy the real workstation and for detecting ergonomic problems that otherwise would be difficult to detect. In conclusion a final workstation configuration is proposed and significant ergonomics improvements are achieved
Modelling and simulation and ergonomic standards as support tools for a workstation design in manufacturing system
No full textIt is the intent of the work to achieve the ergonomic effective design of a workstation belonging to an industrial plant operating in the field of mechanical parts production. To this end, the authors propose an approach based on the integration of modelling and simulation tools and several ergonomic standards. Modelling and simulation tools are used to implement a three-dimensional environment capable of recreating, with satisfactory accuracy, the evolution over the time of the real workstation. The ergonomic standards are accomplished for evaluating and analysing the ergonomic risk level within the system being considered. Workstation modifications are incorporated in the simulation model and the effects (ergonomic risk level) of those changes are analysed for designing an improved workstation configuration in terms of interaction between operators and their industrial working environment.
