Popis: | 98 Large hospitals such as medical centers provide not only medical services, but also are responsible for emergency refuges, medical research and education. With the increasing demands on healthcare facilities and services, hospital buildings have gradually matured to become large capacity and numerous complex facilities. A hospital is a more complex system of interacting environments, in comparison with other kinds of buildings. The performance of hospital buildings depends highly upon the efficiency of maintenance execution. However, with ever-growing demands and decreasing budgets, facilities managers of hospitals must ensure facilities properly maintained without compromising their performance. In order to provide an appropriate environment in such a high-complex building, key maintenance items should be carefully analyzed and executed as well as decisions for proper maintenance budget allocation. Therefore, the purposes of this study are to analyze the key maintenance items of hospital buildings, establish the prediction model for maintenance cost, and develop the decision model for alternatives priority. In the aspect of key maintenance items analysis, three categories are classified, including periodic maintenance, repair, and demand change. This study also identifies the key maintenance items and their sub-items of the National Taiwan University Hospital (NTUH). Besides, this study also compares the differences between NTUH and literatures based on the maintenance cost unit. Results show that: 1. In periodic maintenance, the key maintenance items of both East building and West Building are High voltage (22.1% in East building and 26.1% in West Building), HVAC (26.2% in East building and 25.9% in West Building), and Elevator (13.9% in East building and 15.9% in West Building). 2. In repair, the key maintenance items of East building and West building are: (1) Interior finishes (43.4%), HVAC (24.7%), and Low voltage (9.3%) in East building; (2) Interior finishes (67.3%), Low voltage (10.6%), and HVAC (5.1%) in the West building. The average cost of West building is 2.8 times than East building (22.8 dollars/m2/year in West building and 8 dollars/m2/year in East building). 3. In demand change, the key maintenance items of East building and West building are: (1) Low voltage (52.7%), Boiler (31.3%), Interior finishes (11.1%), and HVAC (4.1%) in East building; (2) Interior finishes (29.9%), Low voltage (27.6%), HVAC (17.9%), and Elevator (16.0%) in the West building. This study not only identifies the key maintenance items but also establishes an effective prediction model for hospital building maintenance, evaluating the tendency of maintenance cost to provide important information for the facility managers. In the aspect of prediction model, this study adopts the grey forecasting model as the main structure and then integrates the exponential series and self-organizing mapping to recognize the regular and irregular residual errors, respectively. The repair records of NTUH are employed to demonstrate the practicability and precision. Results show that the proposed prediction model can catch the tendency of building maintenance cost effectively. Beside, this study provides a decision priority model for maintenance alternatives. The concepts of grey number, grey relational analysis, and weight-setting technique are all integrated into the proposed decision priority model. By defining the uncertain information, the proposed model can flexibly deal with the complex decision problems. |
