Lanner Group Ltd is a discrete event simulation software company headquartered in Henley in Arden, Warwickshire. The business develops, markets and supports business process simulation and optimisation systems. The company has subsidiaries in the USA, China, France and Germany and a distributor network selling the companys products in 2. Lanner Group was formed following a Management Buyout of AT T Istel, a spin off from the operational research department of British Leyland where, in 1. Lanner Group services automotive, aviation, criminal justice, defence and aerospace, financial services and contact centres, food and beverage, health, logistics and supply chain, manufacturing, nuclear, oil and gas, pharmaceutical, and consumer health industries. Company historyeditLanner Group formed in 1. Management Buyout from AT T Istel 2 the company was initially named SEE WHY SOLUTIONS and was incorporated in 1. Lanner Groups previous owner, AT T Istel, formerly known as ISTEL, was initially called BL Systems, and was a spin out formed in 1. Merger of all the computer departments under the then British Leyland umbrella. BL Systems SEE WHY tool, programmed in Fortran 7. Lanner Groups current core software product WITNESS. WITNESS was the first of the industrial strength 4. GL simulators. 1. The WITNESS system was launched on IBM PC in 1. The latest version of Lanners Witness was released in summer 2. The applications of the FORTRAN 7. WITNESS interface have been subject to further academic Research and Development. Since 1. 98. 5 the company has supported its simulation software academic program. Over 1. 00 universities worldwide have been involved since the program began. Lanner Group continued to develop the WITNESS platform further in parallel to developing its mainstay product of the same name, and since 2. PRISM and PX Sim respectively. In 2. Java based simulation engine called L SIM which is embedded in Business Process Management BPM solutions software. In May the same year, a technology partnership with BPM solution provider IDS Scheer was announced. The L SIM product is now the simulation engine of IDS Scheers ARIS Business Simulator. The companys WITNESS platform technology is therefore embedded into current Oracle, SAP, and IBMBPA products. From 1. 99. 6 to 2. On 1. 8 March 2. 01. Lanner Group announced that it had secured a 3 million new investment deal with NVM Private Equity replacing 3i. Lanner Group as a small minority investor. Further readingeditGreasley, A 2.
