Operating Theatre Optimization : A Resource-Constrained Based Solving Approach

The operating theatre is considered as the bottleneck of the hospital and as one of the most resources consuming unit. Therefore its management is of primary interest: an efficient planning allows to use as better as possible the availability of the operating theatre and reduce human and financial working costs. This paper deals with operating theatre planning optimization. We present a mathematical model combining surgeries planning and scheduling over short time horizon, and by taking into account renewable and nonrenewable resources availabilities. This model gets its inspiration from project management and especially resource-constrained project scheduling problem (RCPSP). We also introduce a genetic algorithm approach to heuristically solve the problem. We base our approach on the multi-mode variation of the RCPSP to define the related crossover, mutation and selection operators allowing the global search to work effectively

A Porter-SCOR modelling approach for the hospital supply chain

We suggest in this paper a modelling approach that extends the Analysis Specification Conception and Implementation (ASCI) methodology by putting the accent on the performance dimension. We suggest a value model as an extension of ASCI methodology based on Porters and SCOR models. We underline the necessity of defining an appropriate system of performance metrics that should be defined in accordance with the hospital value system. This extended methodology provides the user with a better understanding of the way the system works and enables to document practices and processes.
