Ensuring the Conservative Process: The Roman Walls of Lugo Maintenance Plan
2016
In 2000 the walls of Lugo were added to the World Heritage List. In the Spanish scenario of UNESCO Sites this is the only one provided with a maintenance plan, which properly defines times for inspections and interventions, tools for the collection and management of data, human and financial resources. This plan has begun to ensure a conservation process which guarantees that this ancient artefact is used efficiently and safely over time. The walls are fully accessible and because of the dominant ramparts are used by citizens as a beloved and frequently used city park. This article aims to describe the strategy and the conservation process put in place on the Roman walls to preserve and kee…
STRUMENTI E METODI PER INTEGRARE GLI ASPETTI AMBIENTALI NELLA MANUTENZIONE DEL PATRIMONIO ARCHITETTONICO
2022
La corretta e costante applicazione della manutenzione può assumere un ruolo chiave per garantire la qualità del patrimonio costruito e il soddisfacimento delle più recenti classi di requisiti ambientali. A tal fine, è necessario che le strategie che guidano la programmazione delle attività di manutenzione siano modellate sulle caratteristiche del manufatto in esame. In Italia una larga parte degli edifici risulta edificata prima del 1946 e, molti di questi seppur non strettamente tutelati dalla legge, possono presentare rilevanti caratteri morfologici o costruttivi che vanno opportunamente conservati. La manutenzione, condotta in un’ottica sistemica e multiscalare, comprendendo interventi …
A simulated annealing-based approach for the joint optimization of production/inventory and preventive maintenance policies
2017
Even if more reliable than the past, the performance of modern manufacturing systems is still affected by machine’s deteriorations and breakdowns. As a consequence, adequate maintenance programs must be implemented to adequately satisfy demands during manufacturing stops due to unexpected failures or preventive maintenance (PM) actions. Despite production and maintenance are closely related issues, their joint optimization has become an important research topic just during the last decade. Therefore, the present paper proposes a model for the combined optimization of production/inventory control and PM policies with the aim of minimizing the total expected cost per unit time. The model is f…
Accentuating the Positive, Eliminating the Negative? Relationship Maintenance as a Predictor of Two-Dimensional Relationship Quality
2012
In this study, relationship maintenance and its connections with positive and negative relationship quality were examined among Finnish parents (N = 177 women and 153 men; i.e., partners from 150 couples and 27 women and 3 men whose partner did not participate in the study). Relationship maintenance was measured using Stafford, Dainton, and Haas's (2000) version of the RMSM and two-dimensional relationship quality using Fincham and Linfield's (1997) PANQIMS. Structural equation modeling was utilized to analyze paired data. Women were found to report more relationship maintenance behaviors than their partners. The results showed further that relationship maintenance was connected with both p…
Proposition du Project APER pour un entretien programé du Quartier hellénistique-romain d’Agrigente / Proposta del Progetto APER per la manutenzione …
2014
The article puts forward a proposal for the planned maintenance of the Sicilian study case chosen by the APER Project: House IA-B in Agrigento’s Hellenistic-Roman Quarter. After a few brief considerations regarding maintenance work on buildings and on architectural heritage, specific details concerning the maintenance of archaeological sites are illustrated. The article proposes a coding system specially applied to domestic Punic, Hellenistic and Roman architecture, designed to identify maintenance units, meaning parts of the archaeological built environment that can be the object of effectively planned maintenance work because they feature similar shapes and materials. This proposal should…
