Jeppesen Systems AB is active in research and development at all levels. All of Jeppesen's major software products undergo continual enhancements. New projects frequently demand the use of new computing and programming technologies with Jeppesen staff continually upgrading their skills and knowledge to meet these demands. Jeppesen also continues to develop methods to enhance the value for clients in consulting projects. Many of the new algorithms for optimization require research at a fundamental level and Jeppesen staff have published many research papers in international journals.
