Abstract Fixturing is an important manufacturing activity. Computer-aided fixture design technique is being rapidly developed to reduce the lead time involved in manufacturing planning. An automated fixture configuration design system has been developed to select automatically modular fixture components and place them into position with satisfactory assembly relationships. In this paper, an automated fixturing planning system is presented in which fixturing surfaces and points are automatically determined based on workpiece geometry and operational information. Fixturing surface accessibility, feature accuracy, and fixturing stability are the main concerns in the fixture planning. The system development, fixture planning decision procedure, and an implementation example are presented in the paper.

This research was done with the aim of facilitating the Admin access to process raw material inventory data which outlets and warehouses are located in different cities. The method used is the SDLC method, which is a method that uses several stages in system development ranging from System Planning, System Analyst, System Design, System Implementation, System Implementation, and System Maintenance. The result of this research is a system that can be accessed by admins to facilitate the work process.

Abstract The purpose of this research is to develop a methodology and a prototype system that allows the integration of product design and manufacturing planning. The task is achieved through an integrated CAD-CAPP-CAFP# environment. The system consists of three major modules, namely, Feature Analyzer, Process Planner and Fixture Planner. The manufacturing information of a part required for process and fixture planning is extracted from the 3-D geometric model and the 2-D engineering drawing, thereby both geometric and non-geometric attributes of a part can be obtained. An integrated approach to process and fixture planning is adopted to ensure that the process plan for a part is generated on the basis of a workable fixture plan. The approaches to feature analysis and to integrating process and fixture planning are introduced.

The practice of brokering is one of the concerns felt by the community at immigration services. The Directorate General of Immigration immediately followed up on the report, and appealed to all technical units of immigration to eradicate brokering practices and the practice of extortion (illegal levies) on immigration services. In line with this appeal, the Directorate General of Immigration made an online application called APAPO. Kantor Imigrasi Kelas II Non-TPI Kediri in follow-up to the practice of extortion and brokering also built the Flip Barrier Gate system. This system utilizes the use of RFID (Radio Frequent Identification) technology embedded in the access card. However, over time, this system began to find some problems. Among the obstacles that have arisen are the inactivity of this system because it is feared that it will become the center of the spread of COVID-19 due to the alternating use of access cards. In this research, development planning is carried out for the Flip Barrier Gate Class II Non-TPI Kediri Immigration Office. Flip Barrier Gate is integrated with APAPO through the use of QR code booking code as an access reader. In development planning, this study uses the system development theory described by Tata Sutabri. This phase consists of 5 stages, namely, system investigation, system analysis, system design, system implementation, system maintenance.

The case of lost or missing children when people go traveling or in the hustle often occurs due to lack of parental supervision. These problems can be solved using Global Position System (GPS)-based navigation technology Location Based Service (LBS). This research aimed to determine the position of members of the community (such as family) who were lost or missing by using mobile devices. Rapid Application Development (RAD) was used for system development, which comprised the step of requirement or planning, system design, development, and cutover. The result of this research is a GPS-based application that is able to display the position of members of the community, the route to the location, and the media discussion (comments). The conclusions show that the application provides an easy and useful function in finding the location of the community member, displays the route to the location, and allows the interaction in the form of communication.

This research aims to help universities that do not have an academic information system and facilitate EPSBED data report to Directorate of Higher Education (DHE). The method used is the three first stages in the System Development Life Cycle (SDLC), which are systems engineering, requirements analysis, and design system. The result is a design of university business process, design of database, and design of user interface. This research finds that DHE has a specific data structure that can represent the basic activities of a study program. Therefore, this system design can be used for reporting of EPSBED data as well as for data collection of study program activities.

Abstract This paper describes a system for the design and production of sheet metal parts. We have designed over sixty test parts with our “Parallel Design” system, and the features are automatically generated as the design progresses. After the design is complete, our automatic process planning system uses the features and generates new ones to aid the production of a near-minimum manufacturing cost plan. Finally, these plans are used to produce parts on an automatic bending system. The results of our Intelligent Bending Workstation outperform human experts in many cases, while achieving a key goal; to complete planning and production in less than 30 minutes. In industry, this process can take substantially longer (in some cases, weeks). Once a plan is produced it can be used to produce the part, and to provide feedback to design and other factory systems. Several key manufacturing problems are considered and the result of planning is used to resolve these problems.

To facilitate the parent company’s push to gain market share, Heineken USA needed to be more responsive to market demand fluctuation. Because of the long lead-time between order and delivery, they found that responding to marketplace changes in a timely fashion was becoming increasingly difficult. In the meantime, major competitors such as Anheuser Busch were responding to consumer demands for fresher products by providing freshness label dating. Heineken USA launched its new Internet based system called Heineken Operational Planning System (HOPS) to allow the parent company to produce the beer closer to the time when they need to deliver it, so the customer receives a fresher product. The new system enables Heineken USA to achieve 50% reduction in the lead-time from order to delivery and 10% increase in sales.

In the development of a modular fixture design system, it is essential to have a modular fixture element database that can be integrated with a CAD system, in addition to the other considerations such as fixture configuration, interference checking, etc., which are also important to fixture designers. This paper describes a new method to create the fixture element database and model the fixturing towers (i.e. subassemblies). By using this method, the database can be effectively created and is easy for use in fixture assembly. The modular fixture tower database is used to represent the subassembly of fixtures. This will simplify the fixture design and assembly process. A built-in interference checking methodology is embedded in the planning stage that will ensure a collision-free fixture design. The system is developed using the knowledge- based system, ICAD, and interfacing with UG-II for modelling the workpiece. Examples of fixture design generated by the system are also provided to illustrate the development.
