Effectiveness was traditionally hunted for by reducing complex schedules into unit tasks scientific work organization and by enabling sequential assembly lines vertical flow-shop . The approach leads to the highest productivity and it is prised for mass production. Flow-lines and fixed schedules however require amortisation plans based on steady programmes on duty horizons corresponding to product volumes exceeding some minimal threshold. Market saturation and trade instability look for quick updating of the offered items properly adapted to wider classes of buyers needs possibly down to the limit situation of one-of-a-kind customised quality. Worldwide enterprises looking for purchasers oriented supply are thus concerned by time-varying artefacts extended mixes of items have .
