Decision Support System for maintenance policy optimization in medicinal gases subsystems

This article shows an innovative decision support system built by integrating Markov chains with the multicriteria Measuring Attractiveness by a Categorical Based Evaluation Technique (MACBETH) for managing medical assets in a Health Care Organization. This model makes a choice of optimal maintenance policies on different typologies of subsystems for the distribution of medicinal gases and vacuum. The model uses a decision group made up of various departmental heads of a Health Care Organization. It should be noted that it has also been applied to a public general hospital.
