AbstractThe trend of globalization has led to a structural change in the sales and procurement markets of manufacturing companies in recent decades. In order not to be left behind by this change, companies have internationalized their production structures. Global production networks with diverse supply and service interdependencies are the result. However, the management of global production networks is highly complex. Key performance indicator (KPI) networks already exist at the corporate level and site level to support the management of complex systems. However, such KPI networks are not yet available to support the management of entire production networks. In this article, a KPI network for global production networks is presented, which links the key figures of the site level and the corporate level. By integrating both levels into a comprehensive KPI network, cause and effect relationship between the production-related KPIs and the strategic KPIs of a corporate strategy become transparent. To this end, this KPI network is integrated into a Performance Measurement and Management (PMM) methodology. This methodology consists of three phases: performance planning, performance improvement, and performance review. For testing the practical suitability, the PMM methodology is applied to the production network of an automotive supplier using a simulation model to estimate the effects of proposed improvement actions of the methodology.

In this paper, we identify the key parameters to consider in a decision model on internationalization of operations. In order to propose these parameters, the GLOBOPE framework was adopted as the basis of this work. This framework contemplates the three commonest challenges of global operations configuration for industrial manufacturing companies in an internationalization process, which are: new facility implementation (NFI); global suppliers’ network development (GSND); multisite production network configuration. A set of suitable parameters is herein provided for NFI and GSND in the analysis stage from strategic, tactical and operational decision levels. These parameters could be used in the future as a basis for the development of quantitative tools for decision making on the internationalization of operations.

AbstractReviewing the burgeoning legal scholarship on global value chains to delineate the legal image of the global value chain and then comparing this legal image with images on global production in neighbouring social sciences research, in particular the Global Commodity Chain/Global Value Chain and the Global Production Network approach, this article reveals that legal research strongly aligns with the value chain image, but takes less account of the production-centric network image. The article then outlines a research agenda for legal research that departs from a network perspective on global production. To that end, it proposes that re-imagining the law in a world of global production networks requires a focus in legal research on the legal construction of global production and its infrastructure and a stronger contextualization of governance obligations and liability rules in the light of the issue-specific legal rules that apply to said infrastructure.

<p>Nowadays, every branch of economic activities is a subject of the various influences in which they cannot have an impact. The capabilities of an enterprise to have a significant impact on business environments can be done through the creation of their own brand. Hence, this has become a tool for the identification of its products and enterprises. Enterprises have exploited brand as a means by which businesses have improved their own turnover, competitive position in the market, and winning the loyalty of their consumers. In Kosovo, there is an increasing trend of enterprises in creating a brand for their own products. Thus, this gives them a higher possibility for identification by the consumers, fosters the development of marketing policies, and provides them the opportunity to break through new markets. The scope of this paper is to determine the importance and rationale for the creation of certain brands. It was able to achieve this through a research of perception for the brands by consumers, as well as finding out grounds and influential factors during their selection of certain brands. The data acquired have proved that there are some advantages of enterprises that have a well-known brand. Also, the various factors which influence customer’s decision include physical product handling features, good experiences, packaging, warranty, etc. The data presented will help in the future for an increase in awareness on the importance of branding in the practice of enterprises. Therefore, this is with the aim of creating a good image for the products as well as enterprises.</p>

The thermal efficiency, work per unit mass, and work per unit volume of the simple Rankine and Brayton cycles are expressed in terms of seven independent variables using a simplified thermodynamic model. By requiring equal efficiency, equal work conditions, and the same maximum cycle temperature for both cycles, two necessary relationships are established between the seven independent variables. These two relationships along with two maximum work conditions produce a method for comparing required and selected properties. These comparisons provide useful guidelines for the selection of the cycle and cycle fluids. The comparison analysis shows that for a given application the more attractive cycle is strongly dependent upon the fluids selected.

International trade in automotive and auto parts has grown rapidly during the last two decades but Southeast Asia's largest economy, Indonesia, is lagging behind in its export performance. This paper uses a comparative perspective in examining Indonesia's role in automotive production networks in the context of the contemporary debate on opportunities for reaping gains from economic globalization through engagement in global production sharing. This research aims to answer two questions; the first addresses the determinants of a country's participation in the global production network, the second asks why Indonesia is being left behind in global production networks. Our analysis is based on the Jones and Kierzkowski fragmentation theory. The unbalanced panel trade data for 98 countries for the period 1988–2007 are estimated using the least square dummy variable method. The results show that in Asian countries, foreign direct investment openness is the most important determinant followed by trade cost, trade openness, competitiveness, and labor quality. Indonesia is being left behind for a number of reasons, such as restrictive foreign investment policies, higher trade costs and remaining high protection in the automotive sector in terms of tariff and non-tariff measure, and a low education level that hampers the absorption capacity in technology.

With the basis that research is one of the most important internal sources for innovation, a new approach to create competence-cell-based production networks focused on research activities is presented. Thus, a research process, specific for competence-cell-based networks, is also described. In this process, which is subdivided in different phases, the competence-cells, as the smallest performance units, are temporarily linked in a production network. They cooperate to carry out industry-oriented applied research to generate new ideas or technologies to be used in innovative products. For this process, an approach for the non-hierarchical selection of the necessary competence cells is also introduced. This selection is accomplished by means of the innovation potential, which is based on parameters that evaluate nearly objectively the innovative capabilities of the competence cells.

Abstract Exhaust expansion joints, also known as compensators, are found in a variety of applications such as gas turbine exhaust pipes, generators, marine propulsion systems, OEM engines, power units, and auxiliary equipment. The motion compensators employed must have accomplished the maximum expansion-contraction cycle life while imposing the least amount of stress. Discrepancies in the selecting of bellows expansion joint design parameters are corrected by evaluating stress-based fatigue life, which is challenging owing to the complicated form of convolutions. Meridional and circumferential convolution stress equations that influencing fatigue cycles are evaluated and verified with FEA. Fractional factorial Taguchi L25 matrix is used for finding the optimal configurations. The discrete design parameters for the selection of the suitable configuration of the compensators are analysed with the help of the MADM decision making techniques. The multi-response optimization methods GRA, AHP, and TOPSIS are used to determine the parametric selection on a priority basis. It is seen that weighing distribution among the responses plays an important role in these methods and GRA method integrated with principal components shows best optimal configurations. Multiple regression technique applied to these methods also shows that PCA-GRA gives better alternate solutions for the designer unlike the AHP and TOPSIS method. However, higher ranked Taguchi run obtained in these methods may enhance the suitable selection of different design configurations. Obtained PCA-GRG values by Taguchi, Regression and DOE are well matched and verified for the all alternate solutions. Further, it also shows that stress based fatigue cycles obtained in this analysis for the L25 run indicates the range varying from 1.13 × 104 cycles to 9.08 × 105 cycles, which is within 106 cycles. This work will assist the design engineer for selecting the discrete parameters of stiff compensators utilized in power plant thermal appliances.

Abstract Use of mathematical optimization methods for synthesis of path-generating mechanisms has had only limited success due to the very complex nature of the commonly used Structural Error objective function. The complexity arises, in part, because the objective function represents not only the error in the shape of the coupler curve, but also the error in location, orientation and size of the curve. Furthermore, the common introduction of timing (or crank angle), done generally to facilitate selection of corresponding points on the curve for calculating structural error, has little practical value and unnecessarily limits possible solutions. This paper proposes a new objective function, based on Fourier Descriptors, which allows search for coupler curve of the desired shape without reference to location, orientation, or size. The proposed objective function compares overall shape properties of curves rather than making point-by-point comparison and therefore does not requires prescription of timing. Experimental evidence is provided to show that it is much easier to search the space of the proposed objective function compared to the structural error function.
