ABSTRACT This paper reports on the development of Factory Optima, a web-based system that allows manufacturing process engineers to compose, optimise and perform trade-off analysis of manufacturing and contract service networks based on a reusable repository of performance models. Performance models formally describe process feasibility constraints and metrics of interest, such as cost, throughput and CO2 emissions, as a function of fixed and control parameters, such as equipment and contract properties and settings. The repository contains performance models representing (1) unit manufacturing processes, (2) base contract services and (3) a composite steady-state service network. The proposed framework allows process engineers to hierarchically compose model instances of service networks, which can represent production cells, lines, factory facilities and supply chains, and perform deterministic optimisation based on mathematical programming and Pareto-optimal trade-off analysis. Factory Optima is demonstrated using a case study of a service network for a heat sink product which involves contract vendors and manufacturing activities, including cutting, shearing, Computer Numerical Control (CNC) machining with milling and drilling operations, quality inspection, finishing, and assembly.

Factory optima：一个基于 Web 的系统，用于基于可重用模型存储库的制造服务网络的组合和分析

摘要 本文报告了 Factory Optima 的开发，这是一个基于 Web 的系统，它允许制造过程工程师基于可重用的性能模型存储库来组合、优化和执行制造和合同服务网络的权衡分析。性能模型将过程可行性约束和感兴趣的指标（例如成本、吞吐量和二氧化碳排放量）正式描述为固定和控制参数（例如设备和合同属性和设置）的函数。该存储库包含表示 (1) 单元制造过程、(2) 基础合同服务和 (3) 复合稳态服务网络的性能模型。提议的框架允许流程工程师分层组合服务网络的模型实例，这些实例可以表示生产单元、生产线、工厂设施和供应链，并基于数学规划和帕累托最优权衡分析执行确定性优化。Factory Optima 使用散热器产品服务网络的案例研究进行演示，该服务网络涉及合同供应商和制造活动，包括切割、剪切、计算机数控 (CNC) 加工以及铣削和钻孔操作、质量检查、精加工和组装.
