The core concept of Software-defined Manufacturing involves the separation of software and hardware. Functionalities are not predefined but can be added later through software changes. This necessitates a suitable software and hardware architecture, which allows for reconfiguration of control software, i.e., the dynamic orchestration of real-time software. Traditional orchestration tools from the realm of non-real-time computing lack real-time support and do not provide means to configure real-time communication channels such as Time-Sensitive Networking. Thus, this work describes an orchestration tool based on Kubernetes, which is capable of orchestrating real-time containers including the necessary communication interfaces required for TSN.

Cutting-edge geometries directly influence tool life and performance. Appropriate cutting-edge geometries can enhance wear resistance, ensure process reliability, and maintain workpiece integrity. In this work, the single-factor and multi-factor abrasive water jet machining experiments were conducted to explore the factors influencing the formation of the cutting-edge, including jet pressure, angle, and number of strokes. It was found that different jetting parameters have varying effects on different cutting-edge parameters. Jetting pressure most impacted the radius of the cutting-edge formation, while angle significantly affected shape factor K. Multi-factor experiments demonstrated that both pressure and tool orientation significantly affect process stability.

In milling, regenerative chattering results in tool damage and poor workpiece quality. Particle filled cavities in milling heads have shown to be usable as a possible remedy for this effect. The application of particle dampers (PD) in manufacturing processes is therefore promising, yet it is not sufficiently investigated. In this paper, the effect of the rotational speed and the introduction of an obstacle grid is investigated through numerical simulation. The discrete element method is used to model the particle filling in the PD cavity. Effectiveness is analyzed through the particle movement and acting forces on the cavity walls.

In additive manufacturing, fused granular fabrication (FGF) can be considered as an alternative to the established filament fabrication (FFF) of thermoplastics. Based on granular feedstock, FGF is easily and economically scalable to higher volume deposition rates. However, the resulting surface quality and bed adhesion are currently challenging, resulting in reduced dimensional accuracy and limited adoption in industrial contexts. The present study investigates a conceptual initial setup of new thermoplastic materials for FGF. The main objective is to develop a time and cost efficient method for material independent determination of process parameters to streamline the integration of new materials.

Centrifugal disc finishing is an effective post-processing operation for the roughness reduction of additively manufactured workpieces. However, the process leads to an edge rounding, which might result in shape deviations – especially if the workpiece is manufactured near net-shaped. In this study, a model based on the discrete element method is used to predict the edge radius of workpieces machined by centrifugal disc finishing. As shown, the model can be applied to redesign the workpiece with local stock allowance in order to reduce shape deviations resulting from centrifugal disc finishing.

In order to enhance customer gathering ability and revenue, matching-based solutions regarding the tenant allocation problem in shopping malls are required. This study addresses the problem using the deferred acceptance algorithm with monetary transfer, aiming to optimize tenant-location matching based on mutual preferences. By implementing and testing the algorithm through simulation experiments, we derive matching results under parameters that are set to be close to reality, which demonstrate strong correlations that have been confirmed in previous literature. This study fills the gap between qualitative rules that should be followed for tenant allocation and its application in real-life situations.

Multi-factory production boosts the global competitiveness of manufacturing companies. However, incompatible IT systems and limited information sharing hinder inter-factory communication. This paper presents case study on developing a technical solution for data exchange and analysis along a multi-factory production following a process model based on a value stream-oriented analysis of information needs. As a result, a demonstrator across three factory facilities is built, encompassing a traceability terminal, 3D printing, milling, and assembly processes, seamlessly integrated with an Internet of Things (IoT) platform offering diverse demand-oriented services. Subsequently, the multi-factory demonstrator is evaluated in production.

This study examines the influence of the presence or absence of advertising on viewer behavior within the television market. Broadcasters offer programming free of charge, relying on revenue generated from selling advertising airtime. However, excessive advertising can decrease viewer interest, necessitating a careful balance between ad ratios, program genres, and viewer ratings. Using a model based on Hotelling’s, this paper explores how variations in viewers’ susceptibility to advertising affect their broadcaster preferences. Specifically, it clarifies the behavioral motivations of viewers who opt for pay TV despite the associated costs.

Continuous purchase behavior of consumers is crucial for the success of subscription-based products and services. Despite progress in comprehending intertemporal consumption decisions, designing effective incentive mechanisms for customer retention remains challenging. This study extends the existent utility models under habit formation and satiation to enhance the desirability of an activity with a monetary reward. The optimal sequence of timing to provide an incentive is identified by numerical simulation under various configurations of parameters, and field experiment results suggest that it is effective to provide an incentive in the middle of the consumption.

A flexible job shop scheduling problem (FJSSP) poses a complex optimization task in modeling real-world process scheduling tasks with conflicting objectives. To tackle FJSSPs, approximation methods are employed to ensure solutions are within acceptable timeframes. Quantum Annealing, a metaheuristic leveraging quantum mechanical effects, demonstrates superior solution quality in a shorter time compared to classical algorithms. However, due to hardware limitations of quantum annealers, hybrid algorithms become essential for solving larger FJSSPs. This paper investigates the threshold problem sizes up to which quantum annealers are sufficient and when hybrid algorithms are required, highlighting the distribution of computing power in hybrid methods.
