报告摘要：

Themass customizationparadigm,incombination with the volatility of globalized heterogeneous markets, directlyaffects industries towards realizing efficient manufacturing networkconfigurations. Modern industrial shop-floors are highly affected by theever-increasing product variety and volatile market demands introduced by thecurrently established mass customization and personalization paradigm.Moreover, The Industry 4.0 philosophy promotes the digitalization ofmanufacturing systems. This results in a transformation of the traditionalmanufacturing systems and creates new capabilities in the subjects ofmonitoring and control. To assist this shift, new modelling practices andcommunication standards should be employed. To that end, this Academic Reportaims to describe the design and operation of manufacturing networks based on amulti-objective decision-making and simulation approach. The above-mentionedapproaches are validated through a real-life case acquired, among others, fromthe CNC machine building industry. Additionally, an investigation on theperformance and viability of centralized and decentralized production networks,by discrete-event simulation models and multiple conflicting user-definedcriteria, under heavy product customization is presented. An assessment of the examinedapproaches, with respect to their responsiveness and suitability for highlycustomer-driven environments is provided, and can be used as a guideline forthe production network design. Finally, this Academic Report includes machinemonitoring techniques for the near real-time identification of machine status,in order to allow a predictive maintenance engine to diminish machine toolfailures. Moreover, an adaptive short-term scheduling mechanism is employed,using monitoring data for the refinement of production schedules based on thecurrent and future conditions of the shop-floor.
