This thesis analyzes the impact of SCADA (Supervisory Control And Data Acquisition) systems on production performance and evaluates their economic viability as an investment. Following a theoretical overview of Industry 4.0, SCADA architectures, and investment evaluation methodologies, the study applies these concepts to a real-world case: the screening line of an industrial composting plant—a client of ECSA Solutions (where the internship took place)—supervised by an Ignition platform. Based on daily data from May 2020 processed via spreadsheet, the line’s OEE (74.70%), Efficiency (89.50%), and Reliability (95.04%) were calculated. Since the data were collected after the system was already installed, the direct impact of the SCADA system itself is not observable; the economic evaluation is therefore conditional, assuming a 30% reduction in breakdown-related downtime attributable to the system and valuing the recovered tonnage based on the yield ratio between input material and marketable compost (47.58%). For an investment of €20,000–€30,000 and a ten-year useful life, the NPV ranges from approximately €36,000 to €56,000, the IRR from 32% to 58%, and the discounted payback period from 1.9 to 3.5 years. Sensitivity analysis reveals that the conclusion depends primarily on two parameters not measured in the case study: if the reduction in downtime falls below 18.1% or the price of compost drops below €9.0/tonne, the NPV becomes negative. The investment is thus justified provided these thresholds are exceeded and the data made visible by the system translate into actionable interventions.
La tesi analizza l’impatto dei sistemi SCADA (Supervisory Control And Data Acquisition) sulle performance produttive e ne valuta la convenienza economica come investimento. Dopo un inquadramento teorico su Industria 4.0, architetture SCADA e metodologie di valutazione degli investimenti, il lavoro applica tali strumenti a un caso reale: la linea di vagliatura di un impianto di compostaggio industriale, cliente di ECSA Solutions, azienda presso cui è stato svolto il tirocinio, supervisionata da una piattaforma Ignition. Sui dati giornalieri di maggio 2020, elaborati su foglio di calcolo, sono stati calcolati l’OEE (74,70%), l’Efficienza (89,50%) e l’Affidabilità (95,04%) della linea. Poiché i dati sono stati rilevati con il sistema già installato, l’effetto dello SCADA non è osservabile: la valutazione economica è pertanto condizionale e assume una riduzione dei fermi per guasto attribuibile al sistema pari al 30%, valorizzando le tonnellate recuperate in funzione della resa tra materiale in ingresso e compost vendibile (47,58%). Per un investimento di 20.000-30.000 € e una vita utile di dieci anni, il VAN risulta compreso tra circa 36.000 e 56.000 €, il TIR tra il 32% e il 58% e il payback attualizzato tra 1,9 e 3,5 anni. L’analisi di sensitività mostra che la conclusione dipende soprattutto da due parametri, non misurati sul caso studio: la riduzione dei fermi, sotto il 18,1%, e il prezzo del compost, sotto 9,0 €/t, rendono il VAN negativo. L’investimento risulta quindi giustificato a condizione che tali soglie vengano superate e che i dati resi visibili dal sistema si traducano in interventi concreti sulla linea.

Abstract
This thesis analyzes the impact of SCADA (Supervisory Control And Data Acquisition) systems on production performance and evaluates their economic viability as an investment. Following a theoretical overview of Industry 4.0, SCADA architectures, and investment evaluation methodologies, the study applies these concepts to a real-world case: the screening line of an industrial composting plant—a client of ECSA Solutions (where the internship took place)—supervised by an Ignition platform. Based on daily data from May 2020 processed via spreadsheet, the line’s OEE (74.70%), Efficiency (89.50%), and Reliability (95.04%) were calculated. Since the data were collected after the system was already installed, the direct impact of the SCADA system itself is not observable; the economic evaluation is therefore conditional, assuming a 30% reduction in breakdown-related downtime attributable to the system and valuing the recovered tonnage based on the yield ratio between input material and marketable compost (47.58%). For an investment of €20,000–€30,000 and a ten-year useful life, the NPV ranges from approximately €36,000 to €56,000, the IRR from 32% to 58%, and the discounted payback period from 1.9 to 3.5 years. Sensitivity analysis reveals that the conclusion depends primarily on two parameters not measured in the case study: if the reduction in downtime falls below 18.1% or the price of compost drops below €9.0/tonne, the NPV becomes negative.
