In the last decades, the increasing use of the power electronic devices in space and military applications has led to the reliability analysis of DC-DC power converters. In this paper the design of a quadratic DC-DC converter has been performed in order to improve both reliability and efficiency. The design is performed by the minimization of objective functions using the GA heuristic algorithm, in order to identify the optimum values of the converter parameters that ensure the desired reliability. A complete reliability analysis of the quadratic converter has been done and the proposed design methodology has been demonstrated by simulation.

As the most Muslim populated country in the world, the availability of the Halal product in Indonesia become critical. In 2014 there are only 11.63% of marketed products in Indonesia are halal certified. The existence of a new system and software will be on-site and follow up audits stages that are essential to do. The purposes of this study are to develop the Halal Audit information system (HAIS) and evaluate the HAIS implementation based on the time-cost Trade-off approach using integer linear programming (ILP). In the development of HAIS, The HAIS architecture of a system was described using Unified Model Language (UML). A single case study in chicken slaughtering company was carried to apply the HAIS software and evaluate the HAIS implementation. The results indicate that Integer Linear Programming can be used to calculate the trade-off between time and cost of HAIS implementation activities, such as software programming activity and software testing activity.

The synchronized development of products and services become crucial to the success of product-service systems (PSSs). Nevertheless, the number of service-specific approaches has been scarce. A human centered design (HCD) approach can provide designers with a feasible design methodology that is integrated into the development of PSSs by understanding about human needs and emerging cultural social trends. In this paper, we propose a human-centered design framework to support the development of PSSs by integrating the international standards with HCD selection and product/service design methods. The proposed framework can be a starting point to guide the development of PSSs for improving user acceptance and satisfaction. In addition, the proposed framework can assist existing businesses with product-oriented PSSs by identifying areas of service improvement and strengthening the long-term relationship with their customers. Furthermore, to investigate the significance of HCD in PSSs, we use an exploratory case study involving a wearable activity tracker, Fitbit.

The flexible job-shop scheduling problem (FJSP) is known as an important problem in manufacturing systems. Many methods have been proposed to solve this problem. The iterated greedy (IG) is one of those algorithms that are widely used in simpler shop scheduling problems. This research proposes a new Telescopic Population approach (TP) to assist the IG in solving the FJSP. The use of TP approach with IG provides an effective method that is also easier to reproduce. The performance of TP with IG proves that the new population approach effectively improves the performance of IG.

Taking the dynamic production of a line in the assembly shop of a company's rear axle as an example, the on-site investigation confirmed the basic data and analyzed the assembly process. Em-plant software was used to model the dynamic simulation of each station on the assembly line. According to the simulation results, the bottleneck process is improved, and combined with ECRS principles in lean production, it is eliminate, combine, rearrange and simplify. Under the actual production conditions, an optimization scheme was proposed. After the improvement plan was implemented, the simulation results showed that the production capacity was significantly improved, the assembly line imbalance was improved, and the company's efficiency was improved.

This research examined supplier integration in New Product Development (NPD) from the suppliers‘ perspectives. The level of supplier involvement in NPD practices and the drivers and barriers of supplier integration in NPD were explored. In this case study based qualitative research; data were gathered from interviews conducted with ten automotive suppliers directly involved in NPD with customer firms. The suppliers to national automakers acquired higher level of integration (in terms of design responsibility, product complexity, specifications provides, influences on specifications, stage of involvement, component testing responsibility, and technological capacities) compared to the suppliers to MNC automakers. Market competition was found to be the main driver for suppliers‘ involvement in NPD while limited knowledge transfer was the major barrier for suppliers‘ NPD integration with customers.

Large multinationals execute business functions based on complex Business Processes (BP). Business Units (BU) have undertaken numerous measures towards enhancing the optimization of complex BP. Intricate relationships exist in presenting the information flow of complex BP. BU employ a variety of techniques to optimize the complex relationships of BP. The Design Structure Matrix (DSM) techniques and Artificial Intelligence (AI) system present an efficient methodology for defining and optimizing collaborative BP. This research presents the applications of both approaches for complex BP modelling and management. The research results demonstrate the effectiveness of integrating AI and DSM as an enhanced decision support for optimizing complex BP.

Prognostic models for maintenance decisions have inherent limitations due to quality & quantity of historical data, assumptions made, and time required in validating models. In this paper, Preventive Maintenance (PM) Intervals, Failure events, cost and maintenance records from Computerized Maintenance Management System (CMMS) are analyzed for reducing downtimes and Operating Expenditure (OPEX). The proposed methodologies for maintenance intervals and replacements with acceptable level of confidence are articulated to asset maintenance of a City Council of Australian Local Government organisation as a case of improved decision making under limited information.

Nowadays, manufacturing systems are equipped with a huge number of digital components. Along with the increasing computing power and connectivity, they are becoming more intelligent and can make decisions on their own. Amongst others, these tasks include the self-optimization and self-configuration of the production system. In addition, such cyber-physical production systems can contribute to the planning phase of a manufacturing system, e.g. when the production process must be adapted to a new product. However, neither appropriate means nor a practical mode of operation are available yet. Hence, it is unclear how manufacturing systems can work concurrently with humans in this phase of planning. Within this paper, we present a method of concurrent engineering that enables manufacturing systems to participate in the planning of production systems.

Retailers have been facing a new height of competition ever since the birth of e-commerce disrupted the conventional, brick-and-mortar business model. With the success of turning a disastrous security incident into a financial success, a case study is built to analyze Target’s innovative approach using Lawson and Samson’s model of organizational innovation capability, which then linked with the concept of customer and brand loyalty. An insight from consumers was also analyzed through the concept of consumer behavior that provides a deeper discussion over the overall service innovation initiatives.
