In the context of this undergraduate thesis, the beneficial aspects of Cellular Manufacturing Systems (CMS) are highlighted, as the conceptual basis of the CMSs and its mathematical expression are presented. Also, the work introduces the concept of Metamorphic Cells, which is a new element in the relevant literature. Initially, the fundamental principles that dominate the aforementioned systems and the advantages that characterize them, over the classic production systems, are mentioned. Subsequently, the act of implementing CMS is conceptually structured. The structural elements of the implementation of CMSs are the design of the cells, their formation, their quality assurance and their reliability during their operation period. After an extensive description of the existing literature, a mathematical model, which takes into account variables related to Cell Formation (CF), Group Layout (GL) and Group Scheduling (GS) is presented, while some small-scale numerical examples contribute to the completeness of the model’s presentation. Finally, the dissertation ends with the presentation of the metamorphic cells. These cells are characterized by the property of the floor, on which they are located, to be transformed and adopt rectangular and triangular geometries. These geometric transformations are achieved because of appropriate internal cuts of initial floor’s geometry. In addition, Theorems 5.2 and 5.3, which were developed in this work, form the explanatory basis of the geometric transformations presented.
