摘要:<正> The pressure of continuous cost reduction drives university management to use resources prudently. In line with the common practice in commercial sectors, maintenance decisions in a university are made after taking into account the results of cost-and-benefit analyses relating to the proposed initiatives. This paper describes an approach to optimizing maintenance of university facilities. The approach involves the measurement of system performance against the consumption of resources in maintenance operations and the financial impact of degraded services. The staff and material costs needed to maintain a given level of asset performance are part of reliability costs. The reduction of resources may necessitate extension of preventive maintenance intervals, and extension of such intervals may degrade asset performance. Poor asset performance will affect university operations. For example, unsafe or unreliable operation of mission critical assets will result in interruption of essential university services, thereby impairing the public image of the university. The financial impact attributable to service interruption accounts for the other part of reliability costs. Reliability worth measured in terms of asset availability and mean-time-between-failures(MTBF) can be weighted against reliability costs to judge the optimality of maintenance decisions. The minimum acceptable asset performance can be established by management through a benchmarking process. The approach presented in this paper can also be applied to manage the maintenance operation of large-scale infrastructure systems.
