最近在成本建模、基于仿真的多目标优化和后最优性分析方面的改进，使成本数据和成本估算集成到一种新的方法中，以支持制造企业经济上合理的决策。将生产工程和财务数据与多目标优化相结合，已被证明可以为实际生产系统开发中的知识驱动决策提供必要的信息。本研究的重点是介绍成本建模技术，该技术专门设计用于将用于评估循环经济概念的方法与单一仿真模型和多目标优化相结合。本研究提供了一个完整的示例，使用仿真模型和从现实世界案例研究（HYDROUSA）修改的数据来说明如何将方法和成本模型应用于最佳投资决策支持。本研究的目的是提供一种方法，以便更好地理解水系统过程的成本结构。文献中现有的模型集中在少数变量上，例如以居民或流量表示的工厂容量对水处理成本的影响。此外，通过推导一个适用的成本模型，将评估循环经济潜力和创新的基于自然的解决方案（HYDROUSA系统）在低能源、绿色生产和最大化过程生产率和效率方面的表现。分析应包括对供水和污水处理服务对环境的经济影响的估计，以及对供水和污水处理服务的财务成本的研究（Camp Dresser & McKee Ltd, 2004）。这项研究将开发一种全面的方法来衡量分散系统中水-能源-粮食关系的性能、可持续性和循环潜力。不同水系统的经济影响将使用不同的工具和指标进行评估。物料流分析（MFA）将用于规划城市与水相关过程的概述，以及整个HYDROUSA nexus供应链的整体水和营养平衡（N和P）。本研究的主要目标是开发、应用、优化和评估现有和拟议的水系统（HYDROUSA）的成本函数，并识别最具成本效益的水系统。结果：通过使用实际数据采集并将其结合到模型中，本研究试图提高水-能量-食物关系的有效性。研究的重点将放在营养管理上，以循环价值链为基础，促进农业、能源和地方经济的发展，并将为基于自然的水管理提供创新、可再生和循环的解决方案。对于HYDROUSA中实施的每一种基于自然的技术，将开发一种适用的独特关键绩效指标，从而能够为分散水系统的可持续性和循环性评估开发一种整体方法。水、能源、食物、环境和经济之间的相互作用是本研究方法的主要目标，该方法将指导导致目标技术循环方法的操作条件。因此，本研究的主要关注点是在水段决策中提出循环经济的新解决方案。本研究首先为成本函数估计提供了一个全面而稳健的方法，其次，它开发了基于一组具有相关物理含义的术语的成本函数。应该强调的是，获得的成本函数是成本分析的一个进步。

Recent improvements in cost modelling, simulation-based multi-objective optimization, and post-optimality analysis have enabled the integration of costing data and cost estimation into a new methodology for supporting economically sound decision-making in manufacturing enterprises. The combination of production engineering and financial data with multi-objective optimization has been proven to provide essential information to facilitate knowledge-driven decision-making in real-world production systems development. The focus of this research is to present the cost modelling technique specifically designed for the integration with single simulation models and multi-objective optimization within the methodology that will be used to assess the circular economy concept. A complete example, using the simulation model and data modified from some real-world case study (HYDROUSA) is provided in this research to illustrate how the methodology and cost modelling are applied for the optimal investment decision support.The purpose of this research is to deliver a methodology for a better understanding of the cost structure of water system processes. The existing models in the literature are focused on few variables such as the influence of the capacity of plant, expressed as inhabitants or flow rate, on the cost of water treatment. Also by deriving an applicable cost model will assess the circular economy potential and the performance of innovative nature-based solutions (HYDROUSA systems) with respect to principles of low energy, green production and maximisation of process productivity and efficiency. The analysis should include estimations of the economic impacts that water and wastewater services have on the environment as well as studies of financial costs of the water and wastewater services (Camp Dresser & McKee Ltd, 2004).This research will develop a holistic methodology to measure the performance, sustainability and assess the circularity potential of the water-energy-food nexus in decentralized systems. The economic impacts of the different water systems will be performed using different tools and indicators. The Material Flow Analysis (MFA) will be performed to plan overview of the water related processes of the city and an overall water and nutrient balance (N and P) throughout the supply chain of HYDROUSA nexus.Scope of projectThe main objective of this research is to develop, apply, optimize and evaluate the cost function for the existing and the proposed water system (HYDROUSA) and recognize the most cost effective water system.Outcome:By using real data acquisition and combine those into modelling, this research try to improve the effectiveness of the water-energy-food nexus. The focus of the research will be on nutrient management, boosting the agricultural, energy profile and local economies, based on circular value chains and will deliver innovative, regenerative and circular solutions for nature-based water management. For each of the nature-based technologies implemented in HYDROUSA an applicable Unique KPIs will be developed, enabling the development of a holistic methodology for the sustainability and circularity assessment of the decentralized water systems. The interactions between water, energy, food, environment and economic is the main goal of the methodology of this research that will guide towards the operating conditions that lead to a circular approach of the target technologies. Therefore, the main concern of this research is to propose a novel solution in terms of circular economy in the policy-making of the water segment.This research firstly contributed to provides a comprehensive and robust methodology for cost function estimation and secondly, it develops cost functions that are grounded on a set of terms with an associated physical meaning. It should be highlighted that obtained cost functions are a step-forward in cost analysis.
