Maintaining public toilets in good condition is essential for public health. Lack of maintenance may render them inefficient and unusable. Overall knowledge of the condition of toilets and prioritising maintenance activities are crucial for optimal enhancement and maintenance. A condition index helps to evaluate the facilities in toilets and categorise toilets based on their condition. To achieve this, a three-level hierarchical structure was developed from the literature search to identify factors and their attributes related to the condition of toilets. Then, a hierarchy process was used to estimate the weights of the factors and their attributes based on expert opinions. Finally, a weighted-sum method was used to develop an index. The developed index was applied to 40 randomly selected public toilet facilities to check the sensitivity of the index to changes in weighting and attributes.

使用多准则决策技术的公共厕所条件指数

保持公厕完好对公众健康至关重要。缺乏维护可能会导致它们效率低下且无法使用。全面了解厕所的状况和确定维护活动的优先顺序对于优化改进和维护至关重要。条件指数有助于评估厕所的设施，并根据厕所的状况对厕所进行分类。为实现这一目标，根据文献检索开发了一个三级层次结构，以确定与厕所状况相关的因素及其属性。然后，使用层次过程根据专家意见估计因素及其属性的权重。最后，采用加权求和法制定指数。
