Narrow Results

Selecting a suitable Multi Criteria Decision-Making (MCDM) method is a crucial step in selecting appropriate medical equipment. The aim of the research is to define the most appropriate tomography equipment through the integration of the Analytic Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method. A hybrid model is presented. The AHP is used to define the weights of each criterion and sub-criterion through qualitative comparisons. Then, TOPSIS is used to evaluate the purchase options. This research provides decision makers with a scientific and rigorous decision support system useful in strategic and complex decision. A numerical example is also presented.

The main objective of this study is to determine the relationship between Lean Management (LM) and World Class Manufacturing (WCM) practices of aeronautical company in Italy. The methodology should help managers to select those principles and tools of Lean Manufacturing and WCM that are expected to be effective in their company. The research aims to integrate the two models and to achieve a global manufacturing performance in order to maximize the company performance. To this end, a methodological approach, based on Fuzzy Cognitive Maps (FCMs) and the Analytic Hierarchy Process (AHP), is proposed to quantitatively evaluate relationships between LM and WCM. The proposed model allows to identify key factors of Lean and WCM practices and to measure the quantitative relationship between these strategies. The final output is a dynamic analysis designed to identify how relations change with each individual factor.
