Banco Alimentare helps nearly one million and a half indigents by donating food subsidised by the European Union and collecting surplus food that would otherwise be disposed of. It is a back-line organisation, also known as food bank: food collected is donated to charities, which provide indigents with either hot meals or a box of items. Much has been analysed in the thesis “The implications of logistics management for the food banking system: the case of Banco Alimentare Onlus” written by Valentina de Micheli: the main additions of this work are a detailed study on productivity and a new investigation on the matrices of flows. The first has been performed starting from the data collected from a survey sent to each regional division of Banco Alimentare. Results have been further detailed by computing the productivity of each activity normally performed inside a warehouse. These have been then used in the last part of the work. The latter regard matrices of flows. The analysis has been produced directly from data extracted from SAP. Differently from Valentina’s work, it was preferred to analyse flows based on their commodity-related flows and on the macro-geographical area. The analysis allowed to understand the direction and the entity of flows; moreover, thanks to two additional pieces of research, it was possible to emphasize the importance of two inbound channels, AGEA and Siticibo, in terms of quantity and variety of flows received respectively. The last part of the thesis is about the optimal logistic configuration for Banco Alimentare. After having implemented the principles of network design, an R code has been written. It receives as input data regarding annual inbound and outbound flows, a list of donors, charities and several other parameters to compute the number and position of all facilities in both echelons of the new network of Banco Alimentare. Different scenarios have been created to see how much total cost varies in relation to different inputs. Total costs are computed for each configuration found. Independently from the final configuration, network design principles suggest adopting a logistic chain with two echelons with transit points. Centralisation should help Banco Alimentare increasing food variety and levelling quantities of food available in different parts of Italy. Nowadays this problem cannot be ignored since an indigent in the North receives on average nearly twice as much the quantity of an assisted person living in the South. The importance of the subject of this thesis lies in the fact that resources that Banco Alimentare can free from optimisation could be better employed for other purposes, such as improving the promising project Siticibo, hosting more educational events (both for an external public or for its employees and volunteers), or to extend its support to an increasing number of indigents. Resources available are limited and strongly depend on the donations and the work of volunteers: their use must be contemplated, to make the most avoiding any kind of loss.
Banco Alimentare aiuta in Italia circa un milione e cinquecentomila persone in estrema poverta fornendo cibo sussidiato ` dall’Unione Europea e raccogliendo surplus che altrimenti andrebbe sprecato. L’azienda e un’organizzazione ` back-line, anche detta food bank: il cibo raccolto viene donato a strutture caritative, che a loro volta preparano pasti caldi o lo cedono agli indigenti. Molto e stato analizzato nella tesi di Valentina de Micheli ` nella sua tesi “The implications of logistics management for the food banking system: the case of Banco Alimentare Onlus”: le principali aggiunte a questa vasto lavoro sono state un approfondimento sulla produttivita ed una nuova analisi sulle matrici ` dei flussi. La prima e stata svolta a partire dai dati di un sondaggio ` inviato a ciascuna divisione regionale del Banco. I risultati ottenuti sono stati ulteriormente dettagliati andando a calcolare la produttivita delle attivit ` a normalmente svolte all’interno di un ` magazzino. Questi sono poi stati utilizzati nell’ultima parte del lavoro svolto. La seconda aggiunta riguarda le matrici dei flussi. L’analisi e` stata svolta a partire dai dati direttamente estrapolati da SAP. Differentemente dal lavoro di Valentina, si e preferito analizzare ` i flussi per categoria merceologica e per macroarea geografica. L’analisi ha permesso di capire la direzione e l’entita dei flussi ` merceologici; inoltre, mediante due analisi aggiuntive, e stato ` possibile evidenziare l’importanza dei canali AGEA e Siticibo, rispettivamente in termini di quantita di flusso ricevuto e cate- ` gorie merceologiche recuperate. L’ultima parte riguarda invece la ricerca della rete logistica ottimale per Banco Alimentare. Dopo aver applicato i principi per la progettazione di reti logistiche, e stato scritto un modello in R ` che, ricevuti in input i dati riguardanti entrate ed uscite annuali, donatori, riceventi e svariati parametri, calcola il numero e la posizione di ogni struttura nel primo e nel secondo livello della nuova rete distributiva di Banco Alimentare. Sono stati creati diversi scenari per vedere come i risultati del modello variano in relazione ai dati inseriti. Vengono inoltre calcolati i costi totali per ciascuna configurazione. Indipendentemente dalla configurazione finale, i principi per la progettazione di reti logistiche suggeriscono l’adozione di una rete logistica a due livelli dotata di transit point. La centralizzazione dovrebbe aiutare Banco Alimentare ad aumentare la varieta di prodotti disponibili ed a livellare la quantit ` a di ` prodotto donabile in diverse zone d’Italia. Attualmente questo problema sussiste e non e trascurabile, dato che una persona ` bisognosa riceve in media il doppio al Nord rispetto al Sud. L’importanza di questo argomento di tesi e legata al fatto che ` le risorse che Banco Alimentare e in grado di liberare potrebbero ` essere impiegate per altri scopi, come potenziare il promettente progetto Siticibo, fare piu eventi di formazione per il pubblico ` o per il proprio staff, oppure semplicemente per estendere il proprio sostegno ad una piu larga porzione di indigenti. Le ` risorse di cui dispone sono limitate e dipendono fortemente dalle donazioni e dal lavoro dei tantissimi volontari: il loro utilizzo deve quindi essere ponderato, in modo da poter fare piu possibile evitando ogni tipo di spreco.

Abstract
Banco Alimentare helps nearly one million and a half indigents by donating food subsidised by the European Union and collecting surplus food that would otherwise be disposed of. It is a back-line organisation, also known as food bank: food collected is donated to charities, which provide indigents with either hot meals or a box of items. Much has been analysed in the thesis “The implications of logistics management for the food banking system: the case of Banco Alimentare Onlus” written by Valentina de Micheli: the main additions of this work are a detailed study on productivity and a new investigation on the matrices of flows. The first has been performed starting from the data collected from a survey sent to each regional division of Banco Alimentare. Results have been further detailed by computing the productivity of each activity normally performed inside a warehouse. These have been then used in the last part of the work. The latter regard matrices of flows. The analysis has been produced directly from data extracted from SAP. Differently from Valentina’s work, it was preferred to analyse flows based on their commodity-related flows and on the macro-geographical area. The analysis allowed to understand the direction and the entity of flows; moreover, thanks to two additional pieces of research, it was possible to emphasize the importance of two inbound channels, AGEA and Siticibo, in terms of quantity and variety of flows received respectively. The last part of the thesis is about the optimal logistic configuration for Banco Alimentare. After having implemented the principles of network design, an R code has been written.
