RPA’s (Robotic Process Automation) usage in organizations has rapidly increased in recent years; as a result, companies have developed high expectations from this technology. However, according to Ernst & Young (E&Y), 30-50% of observed RPA projects initially fail and reveal several risks, which lead to investment losses. Consequently, the RPA project is prematurely retired, and the company is back to the manual process. This premature retirement is mainly because of wrong process selection and the not sufficient company automation (RPA) maturity. Therefore, this paper will introduce the concept of an RPA Portfolio, which will assess the complexity of business processes with a company’s automation (RPA) maturity. The RPA Portfolio is a new innovative concept to simplify and visualize the business process selection for RPA projects, and will help to introduce successfully the right RPA projects.

Digitalization and digital technologies have risen sharply in commerce in form of online offers and advice, even in formerly less technology-based sectors. By using the example of flower shops, the aim of this study is to find out whether customers perceive digital offers to be generally useful or necessary, or if local service is still sufficient. To answer this question, a quantitative survey was conducted in selected flower shops in Germany. 82 customers took part. Although most customers have not yet resorted to an online offering when buying flowers, over 66% of respondents are generally in favor of digital offers in the floristry industry.

The global production tends towards more sustainable manufacturing, which forces manufacturers to constantly change and adapt. In our case, we are considering the FESTO CP LAB 400 production line, primarily designed for the training of personnel in the field of automation, which is essential for maintaining competitiveness in today's world. The production line consists of seven fully automated workstations and one manual assembly workstation, which represents the bottleneck of the production system. The paper presents a comparative study of the lines (human assembly vs. collaborative robot assembly) with an emphasis on economic and environmental aspects. The input parameters of the production line were obtained based on real-world measurements, while the assembly time of the collaborative robot was determined through simulation studies. The results of the study are presented graphically and numerically and confirm the contribution of the introduction of a collaborative robot to the assembly workstation in both financial and environmental terms.

In the area of mobility (transport), great efforts are being made to optimize means of transport. While reducing their mass the main goal is to maintain or even improve the performance of the means of transport. Additive manufacturing allows the production of very complex geometric shapes of products that cannot be made by traditional production processes; therefore it has become one of the significant tools in the design of modern vehicles or their parts. Additive manufacturing, combined with appropriate computer tools for numerical design analysis, also allows optimization of product design by topology optimization. In this paper, concept of topology optimization is applied to the roof carrier of a high voltage cable of electric train. Design optimization process was conducted based on two different optimization criteria: minimized part mass and maximized part stiffness.

The transition to digital manufacturing has become more important as the quantity and quality of the use of computer systems in manufacturing companies has increased. It has become necessary to model, simulate and analyse all machines, tools, and raw materials to optimise the manufacturing process. It is even better to determine the best possible solution at the stage of defining the manufacturing process by using technologies that analyse data from simulations to calculate an optimal design before it is even built. In this paper, Design for Six Sigma (DFSS) principles are applied to analyse different scenarios using digital twin models for simulation to determine the best configuration for the manufacturing system. The simulation results were combined with multi-criteria decision-making (MCDM) methods to define a model with the best possible overall equipment effectiveness (OEE). The OEE parameter reliability was identified as the most influential factor in the final determination of the most effective and economical manufacturing process configuration.

This study focused on the Universal Middleware design for the IoT (Internet of Things) service gateway for the implementation module of the convergence platform. Recently, IoT service gateway including convergence platform could be supported on dynamic module system that is required mounting and recognized intelligent status with the remote network protocol. These awareness concepts support the dynamic environment of the cross-platform distributed computing technology is supported by these idea as a Universal Middleware for network substitution. Distribution system commonly used in recent embedded systems include CORBA (Common Object Request Broker Architecture), RMI (Remote Method Invocation), DCE (Distributed Computing Environment) for dynamic service interface, and suggested implementations of a device object context. However, the aforementioned technologies do not support each standardization of application services, communication protocols, and data, but are also limited in supporting inter-system scalability. In particular, in order to configure an IoT service module, the system can be simplified, and an independent service module can be configured as long as it can support the standardization of modules based on hardware and software components. This paper proposed a design method for Universal Middleware that, by providing IoT modules and service gateways with scalability for configuring operating system configuration, may be utilized as an alternative. This design could be a standardized interface provisioning way for hardware and software components as convergence services, and providing a framework for system construction. Universal Middleware Framework could be presented and dynamic environment standardization module of network protocols, various application service modules such as JINI (Apache River), UPnP (Universal Plug & Play), SLP (Service Location Protocol) bundles that provide communication facilities, and persistence data module.

本文主要研究融合平台实现模块IoT (Internet of Things)服务网关的通用中间件设计。目前，包括融合平台在内的物联网业务网关可以支持在动态模块系统上，需要通过远程网络协议挂载和识别智能状态。这些感知概念支持动态环境下的跨平台分布式计算技术，支持这些思想作为通用中间件进行网络替代。最近嵌入式系统中常用的分布式系统包括CORBA(公共对象请求代理体系结构)、RMI(远程方法调用)、DCE(分布式计算环境)动态服务接口，以及设备对象上下文的建议实现。然而，上述技术并不支持应用程序服务、通信协议和数据的每种标准化，而且在支持系统间可伸缩性方面也受到限制。特别是为了配置物联网业务模块，可以简化系统，只要能够支持基于硬件和软件组件的模块标准化，就可以配置独立的业务模块。本文提出了一种通用中间件的设计方法，通过为物联网模块和服务网关提供配置操作系统配置的可扩展性，可以作为一种替代方案。该设计可以作为硬件和软件组件作为汇聚服务的标准化接口提供方式，并为系统构建提供框架。通用中间件框架可以提供网络协议的动态环境标准化模块、各种应用服务模块如JINI (Apache River)、UPnP (Universal Plug & Play)、SLP (service Location Protocol)包等提供通信设施的应用服务模块和持久化数据模块。在这个物联网网关中，基于通用中间件框架的管理支持和可用于每个管理操作，应用服务组件可以在SNMP(简单网络管理协议)版本1、版本2和版本3上交叉执行。通过对MIB (management Information Base)信息单元的分析，实现SNMP扩展服务模块间的交叉支持和各模块间的系统元信息的独立，从而构建生命周期管理组件。因此，在本研究中，与Dispatcher相关的MIB角色通过接收传入消息和管理PDU (Protocol Data Unit)在RFC 1906网络之间的传输来支持多个并发SNMP消息。研究结果表明，利用通用中间件，上下文对象的动态情况与发布信息的机制和工具可以组成物联网，以标准化模块接口到外部服务客户端，作为硬件和软件平台之间的融合。

This paper describes the process of designing and prototyping a low-cost robotic platform based on existing equipment and projects that enable extracurricular STEM activities in Croatia and beyond. A robotic platform with a differential drive configuration was chosen for education from an early age due to its simplicity and a wide range of cheap and compatible components from which it can be made. From the aspect of integration into extracurricular or curricular activities, the BBC micro:bit ecosystem was considered, enabling block-based visual programming. Components with printable parts make up the assembly of the educational robot. The main steps in designing and creating a robot prototype are presented, which consist of the modelling, 3D printing of robot parts, and assembly into a functional system. After several stages of testing, an interactive workshop was held with 7th-grade primary school pupils. Further work is planned to create educational material for extracurricular STEM workshops.
