Web service control of component-based agile manufacturing systems
Current global business competition has resulted in significant challenges for
manufacturing and production sectors focused on shorter product lifecyc1es, more diverse
and customized products as well as cost pressures from competitors and customers. To
remain competitive, manufacturers, particularly in automotive industry, require the next
generation of manufacturing paradigms supporting flexible and reconfigurable production
systems that allow quick system changeovers for various types of products. In addition,
closer integration of shop floor and business systems is required as indicated by the
research efforts in investigating "Agile and Collaborative Manufacturing Systems" in
supporting the production unit throughout the manufacturing lifecycles.
The integration of a business enterprise with its shop-floor and lifecycle supply partners
is currently only achieved through complex proprietary solutions due to differences in
technology, particularly between automation and business systems. The situation is
further complicated by the diverse types of automation control devices employed.
Recently, the emerging technology of Service Oriented Architecture's (SOA's) and Web
Services (WS) has been demonstrated and proved successful in linking business
applications. The adoption of this Web Services approach at the automation level, that
would enable a seamless integration of business enterprise and a shop-floor system, is an
active research topic within the automotive domain. If successful, reconfigurable
automation systems formed by a network of collaborative autonomous and open control
platform in distributed, loosely coupled manufacturing environment can be realized
through a unifying platform of WS interfaces for devices communication.
The adoption of SOA- Web Services on embedded automation devices can be achieved
employing Device Profile for Web Services (DPWS) protocols which encapsulate device
control functionality as provided services (e.g. device I/O operation, device state
notification, device discovery) and business application interfaces into physical control
components of machining automation. This novel approach supports the possibility of
integrating pervasive enterprise applications through unifying Web Services interfaces
and neutral Simple Object Access Protocol (SOAP) message communication between
control systems and business applications over standard Ethernet-Local Area Networks
(LAN's). In addition, the re-configurability of the automation system is enhanced via the
utilisation of Web Services throughout an automated control, build, installation, test,
maintenance and reuse system lifecycle via device self-discovery provided by the DPWS
protocol...cont'd
The feasibility of adopting clothing mass customisation in South Africa
Abstract: Mass Customisation (MC) is increasingly seen as a strategy to survive in the competitive clothing fashion markets. This importance to retail sales necessitates its consideration in the South African context. There is a paucity of literature on adopting MC so exploring the feasibility of MC for South African clothing manufacturers was a step in understanding what is required from manufacturers. Three corporate clothing manufacturers were selected for qualitative interviews to determine whether they currently exhibit identified competencies from literature considered essential to undertake MC. Two manufacturers exhibited key competencies of communication, human capital, flexibility and technology needed for MC success
A service-oriented approach to embedded component-based manufacturing automation
This thesis is focused on the application of Component-Based (CB) technology
to shop
oor devices using a Service Oriented Architecture (SOA) and Web Services
(WS) for the purpose of realising future generation agile manufacturing systems. The
environment of manufacturing enterprises is now characterised by frequently changing
market demands, time-to-market pressure, continuously emerging new technologies and
global competition. Under these circumstances, manufacturing systems need to be
agile and automation systems need to support this agility. More speci cally, an open,
exible automation environment with plug and play connectivity is needed. Technically,
this requires the easy connectivity of hardware devices and software components from
di erent vendors. Functionally, there is a need of interoperability and integration of
control functions on di erent hierarchical levels ranging from eld level to various higher
level applications such as process control and operations management services. [Continues.
Lean manual assembly 4.0: A systematic review
In a demand context of mass customization, shifting towards the mass personalization of products, assembly operations face the trade-off between highly productive automated systems and flexible manual operators. Novel digital technologies—conceptualized as Industry 4.0—suggest the possibility of simultaneously achieving superior productivity and flexibility. This article aims to address how Industry 4.0 technologies could improve the productivity, flexibility and quality of assembly operations. A systematic literature review was carried out, including 234 peer-reviewed articles from 2010–2020. As a result, the analysis was structured addressing four sets of research questions regarding (1) assembly for mass customization; (2) Industry 4.0 and performance evaluation; (3) Lean production as a starting point for smart factories, and (4) the implications of Industry 4.0 for people in assembly operations. It was found that mass customization brings great complexity that needs to be addressed at different levels from a holistic point of view; that Industry 4.0 offers powerful tools to achieve superior productivity and flexibility in assembly; that Lean is a great starting point for implementing such changes; and that people need to be considered central to Assembly 4.0. Developing methodologies for implementing Industry 4.0 to achieve specific business goals remains an open research topic

A component-based virtual engineering approach to PLC code generation for automation systems
In recent years, the automotive industry has been significantly affected by a number of challenges
driven by globalisation, economic fluctuations, environmental awareness and rapid technological developments.
As a consequence, product lifecycles are shortening and customer demands are becoming
more diverse. To survive in such a business environment, manufacturers are striving to find a costeffective
solution for fast and efficient development and reconfiguration of manufacturing systems to
satisfy the needs of changing markets without losses in production.
Production systems within automotive industry are vastly automated and heavily rely on PLC-based
control systems. It has been established that one of the major obstacles in realising reconfigurable
manufacturing systems is the fragmented engineering approach to implement control systems. Control
engineering starts at a very late stage in the overall system engineering process and remains highly
isolated from the mechanical design and build of the system. During this stage, control code is typically
written manually in vendor-specific tools in a combination of IEC 61131-3 languages. Writing
control code is a complex, time consuming and error-prone process. [Continues.
