In this study, a non-linear mathematical model of tumor growth with immune response, under the effects of chemotherapeutic treatment, is presented. After analyzing the dynamics of the cells and the possible equilibria of the drug-free system, their interactions with the drug are examined. Later on, two cost-efficient optimal control approaches are reviewed, based on Direct Collocation and State-Dependent Riccati Equation methods, and then they are extended further so that they can be practically applied to patients. Ultimately, the results from each method are presented, providing an overall better regimen, when compared to previous studies, by successfully eradicating the tumor and keeping the side-effects of chemotherapy to a minimum.
 </efrbr-expression:summarizationOfContent><efrbr-expression:summarizationOfContent>Ο καρκίνος αποτελεί μια ασθένεια που πρωτοεμφανίστηκε πριν από χιλιάδες χρόνια και εξακολουθεί να παραμένει ένα από τα σημαντικότερα ζητήματα της ιατρικής. Στην παρούσα διπλωματική εργασία  παρουσιάζεται και αναλύεται ένα μη γραμμικό μαθηματικό μοντέλο που προσομοιώνει την εξέλιξη ενός αρχικά μεγάλου όγκου, υπό την επήρεια ενός αποδυναμωμένου ανοσοποιητικού συστήματος και χημειοθεραπευτικής αγωγής. Το πρόβλημα εύρεσης της βέλτιστης δοσολογίας χημειοθεραπευτικού φαρμάκου για αυτήν την περίπτωση αποτελεί μία πρόκληση. Για τον λόγο αυτό, αναπτύσσονται δύο μέθοδοι θεραπείας, βασισμένες στις μεθόδους βέλτιστου ελέγχου Direct Collocation και State-Dependent Riccati Equation, οι οποίες στη συνέχεια εφαρμόζονται σε περιβάλλον προσομοίωσης. Τα αποτελέσματα τους είναι πολύ ικανοποιητικά, καθώς εξαλείφουν τον όγκο επιτυχώς, ενώ παράλληλα περιορίζουν τις παρενέργειες της χημειοθεραπείας στον οργανισμό του ασθενή.</efrbr-expression:summarizationOfContent><efrbr-expression:useRestrictionsOnTheExpression type="creative-commons">http://creativecommons.org/licenses/by/4.0/</efrbr-expression:useRestrictionsOnTheExpression><efrbr-expression:note type="academic unit">Πολυτεχνείο Κρήτης::Σχολή Ηλεκτρολόγων Μηχανικών και Μηχανικών Υπολογιστών</efrbr-expression:note></efrbr-expression:expression><efrbr-manifestation:manifestation identifier="http://purl.tuc.gr/dl/dias/04A1FC78-D069-4245-BDE5-45AB0AC47539"><efrbr-manifestation:titleOfTheManifestation>Mavromatakis_Iason_Dip_2020.pdf</efrbr-manifestation:titleOfTheManifestation><efrbr-manifestation:publicationDistribution><efrbr-manifestation:placeOfPublicationDistribution type="distribution">Chania [Greece]</efrbr-manifestation:placeOfPublicationDistribution><efrbr-manifestation:publisherDistributor type="distributor">Library of TUC</efrbr-manifestation:publisherDistributor><efrbr-manifestation:dateOfPublicationDistribution>2020-02-25</efrbr-manifestation:dateOfPublicationDistribution></efrbr-manifestation:publicationDistribution><efrbr-manifestation:formOfCarrier>application/pdf</efrbr-manifestation:formOfCarrier><efrbr-manifestation:extentOfTheCarrier>1 MB</efrbr-manifestation:extentOfTheCarrier><efrbr-manifestation:accessRestrictionsOnTheManifestation>free</efrbr-manifestation:accessRestrictionsOnTheManifestation></efrbr-manifestation:manifestation><efrbr-person:person identifier="http://users.isc.tuc.gr/~imavromatakis"><efrbr-person:nameOfPerson vocabulary="TUC:LDAP">
