The problem<\/h3>\n\n\n\n

Late payments and crossed debts strain the cash flow of small and medium businesses. These debts are not independent: they form networks of interdependencies where a local failure can have global effects.<\/p>\n<\/div>\n\n\n\n

\n

Our approach<\/h3>\n\n\n\n

We model B2B invoice networks as graphs, where vertices are companies and edges are invoices. Our algorithms identify and offset chained debts to reduce liquidity needs.<\/p>\n<\/div>\n\n\n\n

Scientific grounding<\/h3>\n\n\n\n

A research group spanning Inria, LORIA and Bocconi, at the interface of mathematics, computer science and economics, whose work has led to several peer-reviewed scientific publications.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Why care about inter-company debt?<\/h2>\n\n\n\n

Inter-company debts now form complex networks whose dynamics can weaken the entire economic fabric. The MURENE<\/strong> project studies these networks using models and algorithms to propose new approaches for reducing debts and liquidity needs.<\/p>\n\n\n\n

A complex-systems and graph-theory approach<\/h2>\n\n\n\n

In MURENE<\/strong>, inter-company debt relations are modelled as weighted directed multigraphs, where vertices represent companies and edges represent invoices. This representation supports several objectives:<\/p>\n\n\n\n
