Abstract
Product optimisation is commonly done within a company, even though a product may result from a production chain involving several companies. Exchanging information related to the local optimisation between the involved companies allows for adjusting the local optimisation towards achieving a global optimal product. Making the Pareto fronts of the company-local compromise available to the related partners enables the global optimisation of a B2B2B (Business-to-Business-to-Business). We introduce this technology to manufacturing active corrosion protection coating systems involving nanoparticles, paint producers, and consumers.
