Vincent C. S. Wiers (Schiedam, 1969) graduated as an Industrial Engineer from the Eindhoven University of Technology (EUT) in 1993. He started a PhD project at the same university in the department of Industrial Engineering and completed the project in 1997 with a thesis on the Human Factor in Production Control. Subsequently, he started working at Bolesian/Cap Gemini, focussing on knowledge based technology, supply chain management and advanced planning & scheduling (APS). In 2000 he joined CMG, where he carried out several projects in the field of supply chain management. In 2001, he also re-joined EUT as a researcher. 

In 2003, he started his own consultancy company Twinlog, focussing on the implementation of APS systems. Since 2003, Vincent Wiers has carried out over 40 APS projects. He has implemented planning systems for companies producing metals, chemicals, meat, packaging materials, electronics, carpets, automotive components, tobacco, and companies focussing on transportation, outside broadcasting, rail maintenance, port operations, and others. Apart from implementation projects, Vincent has designed functional architectures, carried out software selection projects, and carried out studies to redesign production control structures and processes. His projects were located in Europe, North-America, Asia and Africa.

In September 2004, his former Cap Gemini colleague Erik Maas joined Twinlog as a partner and worked together with Vincent Wiers for almost 10 years. On July 17th, 2014, Erik stepped on board of flight MH17 heading for Kuala Lumpur, and his life ended a few hours later. Vincent Wiers continued his work for Twinlog alone. 

The first book co-authored by Vincent Wiers appeared in 2004, which was on Practical Production Control, and written together with Prof Ken McKay. It was translated into Japanese and Russian. He participated in the research network on Human and Organisational Factors in Industrial Planning and Scheduling (HOPS). His research was done together mainly with Prof Jan C. Fransoo. In 2011, Vincent Wiers was appointed Industrial Fellow at Eindhoven University of Technology (EUT). Together with Prof Ton de Kok, he started up a course on APS. In 2015, another book by Ken McKay and Vincent Wiers appeared, on Manufacturing Excellence. 

Vincent Wiers has published about 16 journal papers and 5 book chapters. He has written numerous columns for Dutch professional magazines, websites and social media groups. His main research focus is the human factor in production control and the use of decision support systems for production control tasks.
