| Abstract: | The combinatorial angle of management of batch processes or job‐shop for fine chemicals is presented. Indeed, the order of priority for product recipes, which allows one to determine the first batch to be loaded, has a strong combinatorial aspect. When dealing with stochastic algorithms, this aspect requires a precise and non‐redundant numbering of the orders of priority. A fairly complex mathematical study based on a family of pseudo‐orthogonal polynomials provides a non‐recursive formula easy to implement. |
