Development of Bengkulu Traditional Cake Marketing through E-Commerce Media

Ummi shop is a company engaged in the sale of traditional cakes. The sales system used today is a conventional system, where the buyer must come directly to the Garsel Shop to see the products offered. With this system, it will take the consumer's time so that it is difficult to obtain information about the specifications of the product being offered. E-Commerce or in Indonesian, namely electronic commerce is the distribution, purchase, sale, marketing of goods and services through electronic systems such as the internet or television, www, or other computer networks. E-commerce can involve electronic funds transfer, electronic data exchange, automated inventory management systems, and automated data collection systems. At this time, Ummi Store has not used the e-commerce facility so that it is difficult to offer products to consumers who are outside the city. In addition, it can also have an impact that affects the product sales process, namely the ignorance of consumers who are outside the city of the existence of Ummi Shops. The process of selling the Ummi Store will only be carried out if there are consumers who come to the store, while many consumers who are outside the city cannot come or do not know the existence of the Ummi Store. To build this e-commerce system, the tools used to describe the system model are in the form of a data flow diagram (FlowMap), context diagrams, and Data Flow Diagrams (DFD), as well as in database design using a data dictionary and Entity Relationship Diagram (ERD). With the existence of e-commerce is expected to make it easier for consumers to obtain information about product specifications offered by Ummi Stores. Make it easy for Ummi shops to offer or sell their products to consumers who are outside the city. Consumers who are outside the city can find out the existence of Ummi stores by using this e-commerce service and can order without having to come to the store. Make it easy for consumers to process payments because there are several options in the payment process. With a good product data processing or management system that is equipped with security, it will support the performance of the system.

Efficient integration process of production data into Augmented Reality based maintenance of machine tools

With the increasing requirements on machine tools such as higher complexity, individuality and digitization, their maintenance becomes also more complex, which increases time consumption and demands special knowledge. The maintenance engineer can be supported in this process using the Augmented Reality (AR) technology, mobile devices and suitable production data. This requires the integration and adaptation of the maintenance documentation as well as further production systems and their data such as the CAD system, product data management (PDM) system, manufacturing execution system (MES) and CNC. For this purpose, a method is developed that allows an efficient integration process of various production data into an AR supported maintenance documentation. This includes concepts for the integration process of different production systems and data into an AR maintenance system as well as the design of the AR maintenance system architecture. Basis is the analysis of the required production and AR systems, data and processes. The aim of the method is to reduce the high expenditure of the overall planning process and the necessary expertise of the maintenance planner of the AR technology. The developed method is verified with different maintenance scenarios, production systems and data as well as machine tools and AR devices.

Формальные правила продукции объектной нотации для данных, определяемых EXPRESS схемой

Recently, product data management systems (PDM) are widely used to conduct complex multidisciplinary projects in various industrial domains. The PDM systems enable teams of designers, engineers, and managers to remotely communicate on a network, exchange and share common product information. To integrate CAD/CAM/CAE applications with the PDM systems and ensure their interoperability, a dedicated family of standards STEP (ISO 10303) has been developed and employed. The STEP defines an object-oriented language EXPRESS to formally specify information schemas as well as file formats to store and transfer product data driven by these schemas. These are clear text encoding format SPF and STEP-XML. Nowadays, with the development and widespread adoption of Web technologies, the JSON language is getting increasingly popular due to it being apropos for the tasks of object-oriented data exchange and storage, as well as its simple, easy to parse syntax. The paper explores the topic of the suitability of the JSON language for the unambiguous representation, storage and interpretation of product data. Under the assumption that the product data can be described by arbitrary information schemas in EXPRESS, formal rules for the producing JSON notation are proposed and presented. Explanatory examples are provided to illustrate the proposed rules. The results of computational experiments conducted confirm the advantages of the JSON format compared to SPF and STEP-XML, and motivate its widespread adoption when integrating software applications.

Identification of dependencies between product parameters and process stakeholders

In today’s mechanical engineering companies, the rising interdisciplinarity of processes and development teams as well as distributed company locations leads to increased production times and more complex product development processes (PDP), although shorter development times are requested. Especially changes, e.g. component optimization or changed customer requirements, as well as parallel sub-processes, require increased planning to make dependencies visible and estimate expenses.When requesting a change to e.g. a component property, it is difficult to identify on the one hand which processes and technical parameters are affected and on the other hand which stakeholders have to be included in the decision making. It is not yet state-of-the art that stakeholders affected by a change in the PDP are identified and notified automatically by the IT-system. Furthermore, it is challenging to identify indirectly connected stakeholders, which are not linked to changing properties or processes, concerning the changes made.In this paper, a methodological approach is presented, that links the technical parameters with the processes and the different stakeholders, using the example of a PDP for light weight composite components.The procedure comprises the implementation of the PDP for light weight composite, including the process-dependent roles, in a product data management (PDM) system. The process structure is then linked to a Model-Based Systems Engineering (MBSE) tool. By building a system model, the product parameters are linked to the processes and roles. Using the established system model, the direct and indirect dependencies between the technical parameters and the stakeholders are visualized.

A voice-based annotation system for collaborative computer-aided design

AbstractIn this paper, we describe a voice-based interaction mechanism to annotate 3D models directly from a computer-aided design (CAD) modeling environment. The audio signal is captured and automatically transcribed to a textual 3D note, which is attached to the geometry and made available to other product information and business processes across the enterprise via a product data management system. Our approach provides a more natural and intuitive method to capture design and engineering knowledge that is particularly effective when large amounts of information need to be communicated. We discuss the rationale of the software architecture and the value of this modality for capturing knowledge in a collaborative engineering context. Finally, we examine the results of an experiment to validate our proposal. Our results show that 3D annotations are an effective mechanism to communicate design knowledge, which suggests the need for further developments in the areas of multimodal interaction methods and interfaces for CAD and collaborative tools.

EVALUATION OF THE EFFICIENCY OF INTRUSION DETECTION SYSTEMS IN PRODUCTION MANAGEMENT INFORMATION SYSTEM OF A MILITARY-INDUSTRIAL COMPLEX

Security components of the production management information system of the military-industrial complex are a single mechanism that can protect restricted access information from possible violators. If one of the elements of information security does not work efficiency, it will become a problem for the entire defense system of the military-industrial complex. Production management information systems need to take into account all available ways to prevent information leakage to do this, the owners of military-industrial complexes must conduct an efficiency assessment. The article suggests a possible way to solve the problem when considering one of the most important subsystems: intrusion detection system. Currently, there is no methodology for evaluating the efficiency of intrusion detection systems for production management information systems. This system is located on a real object located in the Irkutsk Region and belongs to the military-industrial complex.

Managing knowledge and parameter dependencies with MBSE in textile product development processes

Abstract Today’s mechanical engineering companies are confronted with challenges like new material technologies, shorter product life cycles, increasing interdisciplinarity of the various departments as well as product development across distributed company locations. In the context of lightweight design, Tailored Textiles offer promising potentials to reduce product weight and manufacturing costs. Tailored Textiles are textiles with integrated local reinforcements whose textile properties can be adapted locally during the production due to the textile structures, so that process steps and therefore time and costs can be reduced. However, the production-oriented design of Tailored Textiles is currently very complex. One reason for this is the large number of stakeholders that are involved in the process. In order to make this complexity manageable, it is necessary to develop a common understanding of the textile process chain and to improve communication between different stakeholders. Another major challenge is the identification and management of technical parameter dependencies over the entire product development process (PDP). The aim pursued by this work is to link the technical parameter level of different expert models with the process level of Tailored Textiles PDP, so that expert knowledge is externalized to other stakeholders In this context, Model-Based Systems Engineering (MBSE) is a promising approach. Through the formalized application of modeling, MBSE allows the process accompanying development of a system model, which enables the visualization of the parameter dependencies within the product development process. In this paper, a methodological approach is presented which initially involves modeling the PDP for Tailored Textiles in a product data management system (PDMS). The process is then linked to a MBSE modeling tool. In the modeling tool, the analyzed parameters and their dependencies are set up and visualized. Following this procedure, the feasibility of the design will be evaluated based on a use case.

Integrating the Mechanical Domain into Seed Approach

AbstractData-driven technologies have found their way into all areas of engineering. In product development they can accelerate the customization to individualized requirements. Therefore, they need a database that exceeds common product data management systems. The creation of this database proves to be challenging because in addition to explicit standards and regulations the product design contains implicit knowledge of product developers. Hence, this paper presents an approach for the semantic integration of the engineering design (SeED). The goal is an automated design of an ontology, which represents the product design in detail.SeED fulfils two tasks. First, the ontology provides a machine-processable representation of the products design, which enables all kind of data-driven technologies. Among other representations, the ontology contains formal logics and semantics. Accordingly, it is a more comprehensible solution for product developers and knowledge engineers. Second, the detailed representation enables discovering of intrinsic knowledge, e.g. design patterns in product generations. Consequently, SeED is a novel approach for efficient semantic integration of the product design.
