Effect of applying independence axiom of Axiomatic Design theory on performance of an Integrated Manufacturing Information System: a computer simulation modeling approach

To control manufacturing processes, integration of flows of manufacturing information is an important starting point. In this regard, an effective Integrated Manufacturing Information System (IMIS) which is capable of monitoring, analyzing, and inspecting manufacturing processes properly is critical. Often, most of difficulties in achieving an effective IMIS stem from a poor design for the system architecture. This study particularly addresses the problem of coupling in architecture of an IMIS and its effect on the system performance. This study employs “Independence Axiom” of the Axiomatic Design (AD) theory to deal with the problem and uses “times in process” and “utilized capacities of available resources” as two important criteria for evaluating the system performance. To verify the proposed methodology, a real IMIS is addressed, its stochastic behavior is simulated in Visual SLAM and AweSim (version 3.o) software environment, and the outcomes are analyzed by using logistic regression method for each level of system decomposition. Results of the analyses indicate that fulfillment of independence axiom of AD theory can significantly enhance performance of the concerned IMIS.

A MBD Model-driven Automatic Generation Method of On-machine Measuring Program for CNC Machining

Aiming at the problem that the programming of on-machine measurement in CNC machining process is heavily dependent on operators and the efficiency is lower, a MBD model-driven automatic generation method of on-machine measuring program is proposed. The characteristics of measuring program is analysed and the relationship between the parameters of measuring cycle and the features of MBD model is built. The approach of PMI (product manufacturing information) data identifying and extracting is presented. The scheme for transforming the PMI data and geometric features to measuring cycle parameters is constructed. In order to make the measuring program adapt to the change of probe position which stored in different tool magazine, the way of collecting the position automatically by OPC DA protocol is provided. On the basis of the proposed methods and approaches, an on-machine measuring program generating software system has been developed. The running result of the system is given, and the feasibility and effectiveness of the method were demonstrated.

PERENCANAAN ARSITEKTUR ENTERPRISE BERBASIS CLOUD COMPUTING MENGGUNAKAN TOGAF (Studi Kasus: PT. XYZ)

ABSTRACT PT. XYZ is a manufacturing company engaged in the production of tires. Good business strategy isnecessary for the company to compete with local competitors as well as with other companies in thegroup XYZ. Business strategy is also needed in order to achieve its goal in providing the best servicesfor customers. Support the implementation of information systems and information technology isneeded to support the company's business strategy. Planning of the Enterprise Architecture isnecessary for the company to run its business processes. Enterprise architecture is composed of theBusiness Architecture, Data Architecture, Application Architecture and Technology Architecture.Business processes and organizational activities executed using the data collected, managed,secured and distributed using applications, both custom applications and common applications thatrun over the technology infrastructure and computer networks. The research report in this thesisdiscusses about planning the Enterprise Architecture of Manufacturing Information SystemArchitecture Based Cloud Computing using TOGAF, a case study in PT.XYZ. In planning thisarchitecture using the TOGAF-ADM to pass the following stages: Defining planning the ArchitectureVision, Planning the Business Architecture, Planning the Information System Architecture, Planningthe Technology Architecture, Solutions and Opportunities, Migration Planning, ImplementationManagement, and Change Management Architecture. The research process is done by looking at thebusiness strategy on the manufacturing process and products distribution from PT. XYZ. The resultsof this study are planning the enterprise architecture of manufacturing information system at PT.XYZ to support the implementation of enterprise information systems as a whole, to solve theintegration problems of information systems, and improve effectiveness and efficiency in theimplementation of information technology infrastructure.

Applications of Secured Blockchain Technology in the Manufacturing Industry

The manufacturing industry inclines to worldwide business operations due to the economic advantage of product design and development. In this way, globalized manufacturing supply chains make their management and control more difficult. As a distributed ledger technology that ensures transparency, trust, traceability, and cybersecurity, blockchain technology promises to ease some global manufacturing operation problems. This chapter presents blockchain technology basics and analyses the issues (e.g., traceability, cybersecurity, flexibility, and smart contracts) related to the blockchain-based manufacturing information system. Next, the chapter presents related research work in the manufacturing industry in recent years. It also includes a classification mechanism for manufacturing information systems based on specific properties. It is followed by discussing the critical issues that need to consider in designing industry-specific reference information system architecture. Finally, the chapter discusses the scope of future research.

Growing Oklahoma's Workforce Readiness Through Micro-Credentials

The Oklahoma State System of Higher Education is undergoing a rapid transformation which has been accelerated due to the onset of COVID-19. As the pandemic worsened throughout 2020, Oklahoma's unemployment rate skyrocketed to historic levels. Despite this unfortunate circumstance, numerous job openings are available, particularly among critical occupation areas, such as advanced manufacturing, information systems, technology, healthcare, and management. In order to meet this employment demand, the coordinating board of higher education in Oklahoma, the Oklahoma State Regents for Higher Education (OSRHE), sought additional ways to equip Oklahoma college students, particularly those students with some college and no degree, with the necessary professional capital to compete for these jobs. Concurrent with the national trends, OSRHE staff began researching opportunities to validate the ongoing achievements of students through implementation of micro-credentials and digital badging.
