Dr. Murray A. Geisler, 68, an authority on logistics who developed computer and other management techniques to solve logistical problems for the Air Force and other agencies, died of leukemia Aug. 6 at his home in Los Angeles.

From 1948 to 1954, Dr. Geisler worked for the Air Force at the Pentagon on a pilot study called Project SCOPE, an acronym for "scientific computation of optimal programs." What came out of it were statistical and mathematical models of logistical needs and the use of the first large computers to keep track of them. Similar techniques have since been widely adopted in government and industry.

The work set the course of Dr. Geisler's career. From 1954 to 1974 he directed logistics research at the Rand Corp. in Santa Monica, Calif. He taught at the Massachusetts Institute of Technology for a year and then returned here as senior logistician at the Logistics Management Institute, a nonprofit research organization in Bethesda. He retired in 1983 and moved to Los Angeles but continued to advise the institute as a consultant.

Dr. Geisler, a former resident of Bethesda, was born in New York City. He graduated from City College of New York and earned a master's degree in statistics and economics at Columbia University. He earned a doctorate in statistics at Stanford University.

He first moved to Washington in 1941 and worked for the Office of Price Administration, a World War II agency. Later in the war, he served in the Army Air Forces at the Pentagon. He went into the Air Force Reserve and retired in 1977 as a colonel.

In 1946, after returning to civilian life, he went to work for the Air Force, where he remained until joining the Rand Corp.

Dr. Geisler was a member of the Air Force Scientific Advisory Board and the editorial board of the Naval Research Logistics Quarterly. He was a trustee of the Washington Operations Research Council, a professional group, and a fellow of the American Statistical Association. He received the Exceptional Civilian Service Award from the Air Force.

Survivors include his wife, Margaret S. Geisler of Los Angeles; two children, Gary Evan Geisler of Reston and Lauren Sonia Geisler of Asheville, N.C.; two brothers, Gerald, of Santa Monica, and Martin, of Westport, Conn., and one sister, Lillian Smith of Long Island, N.Y.
