## About Greycon

VC Fund · London, United Kingdom

Greycon is the world’s leading provider of production planning, scheduling, forecasting & manufacturing execution systems, that have been designed specifically for roll-based & flat sheet industries. They operate throughout the world. Their strength is the extensive range of specialist software solutions for Plastic Films, FlexiblePackaging, Nonwovens, Metals, Converting and Paper & Board industries supported by powerful optimisation algorithms and a highly experienced team of consultants.These industries are compelled to lower costs, improve production & supply chain efficiency, and increase customer service, specifically in terms of delivery accuracy, reliability & visibility and shorter lead times. Companies that succeed in improving performance in these areas are the most successful and are forcing their competitors to follow suit. Manufacturing companies are relying on optimisation, manufacturing execution systems and supply chain management initiatives. Greycon’s strength is in providing a suite of solutions that understand the complexity of roll-base and flat-sheet material production, from primary machine producing the master rolls, through to the final cutting and converting operations. The same challenges and opportunities arise in production of paper and board, flexible packaging film, photovoltaic film, nonwoven products, specialist steel, aluminium and copper rolls & tubes. During production the variants in the specification of products, the permutations in the allocation of orders, the complexity of scheduling rules and the importance of real-time production feedback, allow an industry-specific solution to significantly out-perform the general Supply Chain/APS/Manufacturing Execution System (MES) solutions.
