Tentative formulas for calculating the cost of maintaining educational communications equipment are proposed. The formulas are based on a survey of campuses of the State University of New York. The survey analyzed the types of equipment to be maintained, types of maintenance, who uses the equipment, who services the equipment, and the cost structure of equipment maintenance. Two types of maintenance were determined: scheduled, which includes preventative maintenance, cleaning, and operation of equipment; and demand, which includes all nature of repairs, corrective maintenance, and refurbishing of equipment. The three types of equipment covered are television, audiovisual, and special or auxiliary equipment. The formula for television equipment maintenance is 4.42% of total capital investment. Of this 2.45% is spent on personnel and 1.97% on supplies and expenses. For audiovisual equipment, the formula is 6.22% of total capital investment, broken down into 3.92% for personnel and 2.7% for supplies and expenses. Specialized equipment is that which could best be assigned to a service contract. (JK)
