In this paper a new heuristic algorithm based on the GTBM (Global Throughput Buffer Management) method is proposed questioning the Theory of Constraints which was originally published in the early 90´s and also the method of dominant throughput applied in environments with shared resources and bottlenecks with variable location. It has been based on the typical configuration of discrete flow processes with parallel activities unbalanced and I made a simulation for comparative information. I saw that the new algorithm can overcome the traditional way of resolving the mix of product-service in terms of higher gross contribution margin and also could identify possible future research such as the application of variable transfer batches in order to increase the output rate without changing the productive resources.
