In these days, manufacturing organizations are facing global competition and short technological cycles. The flexibility of an enterprise and its ability to respond to miscellaneous customer requests decide the competitiveness in the global market. It also requires that the manufacturing plant must reorganize efficiently to produce various products at low cost and short time. This flexibility in the manufacturing process must be able to accommodate various tasks to share resources under safe and efficient control. In the current development processes of manufacturing systems, information handling usually is an undeveloped area. Domains such as design, validation, and deployment will be separated and isolated. One reason for the redundant non-value-added implementation of the component model is that existing system development largely consists of isolated sub-processes that generate proprietary information such as control logic, simulation models, etc. This paper focuses on introducing an innovative software environment, EMBench, which integrates mechanical design, control configuration, simulation and deployment services seamlessly for manufacturing automation systems. Its auto-generated user-friendly GUI (Graphical User Interface) supports direct commanding to the controller at different layers, and internal data (control/mechanical) and model (simulation/physical) mapping eliminates redundant and error-prone manual data entry and model replication at different stages. This tool provides a means of layered and encapsulated services so that complex systems can be designed, configured, simulated and deployed hierarchically with various levels of details. IEC61499 is an emerging industrial standard for distributed industrial process measurement & control systems. Using IEC61499 function blocks and service layer architecture, control services ranging from basic joint servo, to kinematics of a mechanism, to trajectory interpolation, to language parsing and HMI processing, to complex multiple resources/processes coordination can be configured for an application. With the adaptation of IEC61499, EMBench serves as a modular, component-based design, simulation and prototyping tool for shop floor control. Several case studies are presented in details and various potential usages in different fields are discussed. EMBench uses IEC61499 as a means for modularization and reuse of control services.

Real World Situation

Lean manufacturing is a management philosophy derived from Toyota Production System (TPS) which aims to increase the overall values of the product or service provided to the customer through elimination of non-value added activities. In the era of globalisation, to remain competitive in the global market, many medium and small sized Indian industries adopt lean manufacturing. This paper focuses on implementation of lean manufacturing in Indian MSMEs. To examine the implementation, attributes which influence lean manufacturing are obtained and industries’ performances on these criteria are rated. In this paper, the methodology selected from many of the multi criteria models is the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). In the actual real world situation, because of the unreliable nature of the information gathered, the attributes are often not absolute and are imprecise. These data can be considered as fuzzy and the aim of this paper is to adopt TOPSIS decision making method to problems with fuzzy data. The rating and weights of each data are expressed as triangular fuzzy numbers. These attributes are then normalized and the TOPSIS methodology is carried out to determine the effect of implementing lean manufacturing technique in an industry. The best industry is identified by fuzzy TOPSIS on the basis of performance towards the considered attributes is consistent with results identified by TOPSIS.

Exact And Approximate Methods

To secure a competitive position in the global market, the Ready Made Garment (RMG) sector in Bangladesh has been facing various challenges including the improvement of industrial operational performance. Among the various operational issues, balancing the cycle time along the production line is felt to be a common and effective way for enhanced performance. There are numerous exact and approximate methods which have already been proposed and are available in literature for repetitive batch production. Unfortunately such approaches are rarely applied in the real RMG shop floor presumably due to the enormous efforts needed to align with the frequent changes of product lines. Compared to the exact and approximate methods, adoption of lean tools like VSM and Yamazumi chart is highly acclaimed for their simpler and wider applicability with superior capability in addressing and solving the balancing problems. So for balancing purposes of the RMG shop floor an attempt is made to frame and apply an integrated model combining the VSM and Yamazumi chart as presented in this article. Depending on the theoretical framework, operational performance of an RMG shop floor is evaluated upon balancing the cycle time. In doing so, firstly a current state map (CSM) and the corresponding Yamazumi chart are plotted to comprehend the existing operational procedure and analyse the workstation cycle time with respect to the takt time. Using the Yamazumi chart, the workstations are reorganized to reduce or eliminate the non-value added activities, to introduce parallel workstations, and to merge workstations so that a balanced production line is attained. Performance is then assessed by means of Overall Effectiveness of Equipment (OEE), Capacity Utilization and Efficiency. The results as obtained through testing a real life case study of RMG industry, ensure the effectiveness of the integrated system of VSM and Yamazumi chart to identify the wastes, restore the line balance and improve operational performance.

Frequency Identification

As a key advanced manufacturing technology in next generation manufacturing systems, radio frequency identification (RFID) technology is considered to be one of the most promising technological innovations with the potential to increase visibility and improve efficiency. Therefore, research about RFID and its applications are increasing by blasting with all kinds of RFID models in various fields, especially in manufacturing. By introducing RFID technology into the job-shop floor, this paper proposes a systematic RFID-driven graphical formalized deduction model (rfid-GFDM) for describing the time-sensitive state and position changes of work-in-progress (WIP) material flows and guiding where to deploy RFID devices and how to use them for collecting real-time on-site data. Four steps including RFID configuration based on the process flow model, state blocks model, automatic event generation, and extended event-driven model are proposed one by one to support the implementation of rfid-GFDM. The nature of RFID technology is revealed, too. A use case about a computer numerical control (CNC) milling system is studied, and it demonstrates the feasibility of the proposed model. Finally, the possibility of popularizing the model to other field is discussed, too. It is expected to establish a normative RFID modeling method that will facilitate the convenience of RFID applications in a broad scope.

Specific ways of the emergence of new actors in the global market of pharmaceutical goods is investigated, with substantiating the role of transnational corporations (TNC), their investment and technologies in establishing pharmaceutical industries in developing countries. The cases of Puerto Rico and Ireland are taken in order to demonstrate the background for expansion of manufacturing of medicines and medical products and analyze the tendencies in their export capacity building. The factors making pharmaceutical TNC transfer production facilities to India and China are substantiated and implications of this process are highlighted. It is revealed that due to the production internationalization, countries that had been net importers of pharmaceuticals just several decades ago have joined the group of key suppliers to external markets. Because American and European TNC are leading in the pharmaceutical industry by R&D expenditure, they are the principal holders of advanced technologies in the industry. It follows that manufacturing of medicines and medical products in most part of countries either directly or indirectly depend on innovative products of TNC and their technology transfer via various channels (both licensing and imports of components, active pharmaceutical ingredients in particular). It is shown that with the emergence of new market actors coming from developing countries, traditional approaches to determining comparative advantages of counties in the global trade need to be improved. The cases of countries that are recipients of foreign technologies, on which territories powerful high tech pharmaceutical production facilities with high shares of intermediate consumption and heavy export supplies are located due to TNC investment or local public-private capital, give evidence that the classical RCA indicator allows to measure visible comparative advantages in the trade in goods rather than revealed ones. It is proposed that analyses of advantages at country level should include the indicator of high tech goods supplies, to provide for a more accurate description of the innovation component in advanced industries. A new approach to the assessment of comparative advantages of high tech pharmaceutical manufacturing is proposed and tested, which is based on the principle of specialization and use of the ratio of Comparative Advantage in Value Added Activity (CAVA) in particular. It is revealed that the pharmaceutical industry of Ireland, Jordan, Singapore, India or Columbia, with reliance on foreign investment and technologies, could gain advantages in value added creation and dominate the national economies. It is shown that Ukraine is enhancing the advantages in value added creation in the pharmaceutical industry; is it substantiated that due to low R&D and innovation performance and heavy dependence on imported components, capacity building of this industry and its current advantages result from global tendencies and global market conjunctures rather than from the implementation of the national science & technology priorities. According to the author’s recommendation, the proposed approach to determining comparative advantages in value added creation should be used for the assessment of other high tech industries, apart from the pharmaceutical industry, and that is should be supplemented by statistical tools for analysis of foreign trade in finished and intermediate high tech goods.
