Implementazione di tecniche di Total Productive Maintenance all'interno di un sistema produttivo. Il caso Bonfiglioli riduttori Spa

Nell'elaborato viene trattato il processo di implementazione di tecniche di Total Productive Maintenance (TPM) su di un impianto pilota all'interno dell'azienda Bonfiglioli Riduttori S.p.A. Dall'analisi dei dati dello storico degli interventi a guasto, effettuati sull'impianto, si sono ottenuti i parametri manutentivi di interesse per avere un quadro generale della situazione di partenza e sono state identificate due tipologie di manutenzione, come previsto dal TPM: l'automanutenzione affidata agli operatori e una serie di interventi programmati di preventiva a carico dell'ente manutenzione. Sono stati effettuati anche una serie di interventi migliorativi per incrementare l'efficienza dell'impianto. In conclusione sono stati confrontati i parametri di partenza con quelli di fine progetto per valutare i miglioramenti conseguiti valutando anche l'aspetto economico degli investimenti fatti. Dai dati ottenuti alla fine del percorso, sono state fatte le dovute considerazioni e sono stati proposti degli elementi di riflessione.

Productive parameters of seawater and epipelagic plankton and mesozooplankton biomass at stations of R/V Akademik Mstislav Keldysh during 1994-1998

Calculated and measured estimations of biomass of small (<3 mm), large (3-30 mm), and total zooplankton were verified (compared). These integral parameters of epipelagic communities were estimated by two methods. We used previously obtained regression equations, which correlate these parameters with water transparency. Measured values of aforesaid parameters were compared with their mean values in waters of different productivity estimated from NASA satellite maps. We compared data collected at fifteen stations in September-December in regions of different productivity in the North Atlantic. In warm regions (to the south of 40°N) measured and calculated values coincide well. In boreal regions in autumn bulk of mesozooplankton descends to deep layers due to seasonal migrations; hence correlation between measured and calculated values is disrupted. It is evident that correlation between water transparency and mesozooplankton biomass (integral index of water productivity) obtained before should be corrected for seasonal variations.
