Professor Kolesar studies quality management and statistical quality control as well as applications of operations research and statistics, particularly in relation to the management of production and service systems. His recent research includes building models for the analysis and design of service systems with random cyclic customer demand patterns, accelerating the implementation and effectiveness of total quality management systems and optimizing credit-screening procedures. He was awarded the 1975 Lanchester Prize--the highest award in operations research--for work on the logistics of such emergency services as police and fire departments and for contributions to the design of the New York City Fire Department’s Computerized Control System. Kolesar was twice the examiner for the Malcolm Baldridge National Quality Award, and is an associate editor for Interfaces and the Quality Management Journal, and also a consultant to numerous firms and government agencies.
