ABSTRACT

For efficient operation and maintenance of Large Public Research Infrastructures (LPRIs) built with expensive equipment and operating engineers, reasonable budget needs to be allocated. However, it is difficult to fulfill sustainable operation and maintenance (O&M) because there is no standard on budgeting for efficient LPRI operation. There have been a lot of cost assessment studies regarding O&M of high demand facilities such as hospitals, hotels and residential buildings, but a very few on sustainable O&M of LPRI. The objective of this paper is to propose a cost assessment model for sustainable operation and maintenance of large public research infrastructures. Actual O&M data of six LPRIs are collected, and cash flow model and regression analysis model are used for development and evaluation a combined cost assessment model (CAM). When O&M cost estimated by CAM is compared with actual O&M cost of LPRI, the actual O&M cost is 21% less than the estimated cost. The result implies that O&M cost of existing LPRI may have been over or under appropriated than the reasonable standard for efficient operation, and it reveals that it is necessary to establish a budgeting standard for sustainable O&M.

摘要

为了高效运行和维护使用昂贵设备和运行工程师建造的大型公共研究基础设施 (LPRI)，需要分配合理的预算。然而，很难实现可持续的运维（O&M），因为没有标准的预算来保证 LPRI 的高效运行。关于医院、酒店和住宅楼等高需求设施的运维成本评估研究有很多，但关于LPRI可持续运维的研究很少。本文的目的是为大型公共研究基础设施的可持续运营和维护提出一个成本评估模型。收集6个LPRI的实际运维数据，现金流模型和回归分析模型用于开发和评估组合成本评估模型（CAM）。CAM预估的运维成本与LPRI的实际运维成本相比，实际运维成本比预估成本低21%。结果表明现有LPRI的运维成本可能高于或低于有效运行的合理标准，表明有必要建立可持续运维的预算标准。
