A new reengineering methodology for the product-driven system applied to the medication-use process

The aim of the medication-use process (MUP) of a hospital consists in preparing the medicines for each patient every day. The reengineering of the MUP is an important challenge in order to reduce medication errors and costs for the pharmacy. This paper deals with a new methodology of modeling the interactions with the hospital information system (HIS). This methodology is inspired by component-based approach, the paradigm of system of systems (SoS) and the methodology ASDI (analysis–specification–design–implementation). First, the paper shows how the MUP can be compared to a holonic manufacturing system (HMS). So then, the goal of the new methodology proposed consists of designing easily a library of components for an HMS and more specifically for a MUP in a hospital. Finally, an example of the application of this modeling to the hospital of Clermont-Ferrand is presented. The goal is to help the pharmacists to make up their decisions in order to reorganize and design a new pharmacy of a hospital.
