Two aspects of the operation and maintenance of the Suburban Park School District (SPSD) facilities are analyzed: (1) The allocation of funds to operation and maintenance, and (2) the individual custodial workloads. The maintenance and operation expenditures are divided into three categories (custodial salaries, operation expenditures above and beyond custodial salaries, and plant maintenance expenses) and are compared with national norms. The allocation of workloads for custodial staff members is analyzed in terms of efficiency, management's demand for custodians' time, and equalization of duties among custodians. A mathematical model is also constructed to facilitate administrative decision making in the areas of capital expenditures for and manpower utilization of maintenance equipment. It investigates the trade-off between men and machines in the floor scrubbing and water pickup processes. Four recommendations to SPSD resulted from the study: (1) Reevaluate the work assignments and task efficiencies of the custodians, (2) maintain present custodial staff size, (3) reassign individual custodial workloads to promote equalization of assigned duties, and (4) purchase the optimal mix of cleaning machines.
