Literature on performance measurement in waste management service, usually considers assessment tools and methods that focus only on a specific dimension of performance and lacks methods and models that simultaneously consider more dimensions. In this study, adopting the fuzzy logic expert system, we propose a performance measurement model that simultaneously considers three performance dimensions: profitability, financial characteristics and efficiency. To show its empirical implementation, a quantitative analysis was developed regarding the service provided in the 106 Italian provincial capitals that have different owner structures (private, public and mixed). As output, the fuzzy logic system approach adopted generated a rating for the assessment of the performance of the entities, and then a ranking of the cities based on the same. The main results show that: 1) the public owned companies that provide the waste management service have an overall better performance than those with private or mixed ownerships; 2) cities that entrust the waste management service to the same company do not occupy an adjacent position in the ranking.

As practical implications, the proposed model can help public administrators: a) to control the outcomes of their entities (as the TARI); b) to make a decision whether to provide solid waste management services directly or through a private entity chosen to provide the service in return for a negotiated fee; c) to compare waste management services provided in different cities in an objective way and to monitor their performance over time, with the aim of achieving continuous improvement. The model's outcomes are useful to assist public managers and politicians in assessing the compliance level of performance goals related to the solid waste service; while the overall performance index is a useful tool to assist the decision-making process leading to change either fully or partially, their nature from public to mixed or private. The proposed method is able to formalize and automate the decision-making process concerning the evaluation of the performance of waste management, reducing the distortions of the political and environmental context.

使用模糊逻辑系统方法重新思考绩效测量模型:对废物管理所有权的执行性探索

废物管理服务绩效测量的文献,通常考虑只关注绩效的特定维度的评估工具和方法,缺乏同时考虑更多维度的方法和模型。在本研究中,我们采用模糊逻辑专家系统,提出了一个同时考虑三个绩效维度的绩效衡量模型:盈利能力、财务特征和效率。为了展示其经验实施,对 106 个意大利省会城市提供的服务进行了定量分析,这些省会拥有不同的所有者结构(私人、公共和混合)。作为输出,所采用的模糊逻辑系统方法为实体的绩效评估生成评级,然后基于相同的城市排名。主要结果表明:1)提供废物管理服务的公有公司总体上优于私有或混合所有制的公司;2) 将垃圾管理服务委托给同一家公司的城市在排名中不占相邻位置。

作为实际意义,建议的模型可以帮助公共管理者: a) 控制其实体(作为 TARI)的结果;b) 决定是直接提供固体废物管理服务,还是通过选择提供服务的私营实体提供服务,以换取协商费用;c) 以客观的方式比较不同城市提供的废物管理服务,并随着时间的推移监测其绩效,以实现持续改进。该模型的结果有助于帮助公共管理者和政治家评估与固体废物服务相关的绩效目标的合规水平;虽然整体绩效指数是一个有用的工具,可帮助决策过程完全或部分改变其性质,从公共变为混合或私人。
