«The optimal performance of groups of elevators has been a problem of long standing.»

Author’s Biography

The initiator of this website and author of the book ’’The planning and performance of groups of elevators’’, Pieter J. de Groot, studied electrical engineering at the MTS in Haarlem, NL

In 1957 he was employed by Schindler Switzerland as a sales engineer. In 1959 he was seconded to the Schindler Agents in Hong Kong, The Jardine Engineering Corporation Ltd (JEC).

In 1960 he was employed by JEC as sales manager for their Schindler elevator division. This was the beginning of a long career in elevator contracting in Hong Kong and other cities in the Far East and Australia. 

In 1972 he was appointed Schindler Area Manager for Asia-Pacific. In this capacity he initiated and managed the formation of Jardine Schindler (Far East) Holdings SA (1974) and Schindler Lifts (Australia) Pty Ltd (1980). His involvement in the planning of many tall buildings caused a profound interest in the theoretical performance potential of groups. 

In 1975 de Groot met Mr. Leo Weiser Port (†1978) the person who invented destination group controls and realized the first such group in Sydney, Australia during the late 1960’s. De Groot noticed that this type of control should enable optimal group performance. After this meeting he promoted the re-incarnation of destination group controls by the Schindler group. Several years later the Schindler group successfully re-introduced destination controls on the basis of modern technology.

After retirement from Schindler de Groot decided to do his own research concerning the theoretical performance potential of groups and discovered the inherent relativity of group characteristics. This discovery enabled him to design intelligent destination group controls. He was awarded two United States Patents for his intelligent destination control systems (2012 and 2013).
