Reliability Demonstration Test (RDT) is a stress testing to determine whether the product will meet a specified reliability goal and time. Often being discussed is the method in performing the RDT, but the detailed steps in developing RDT is seldom being shared, especially on new product development with no correlation to field data. RDT is a hypothesis testing, failure in using the effective RDT plan will cause disputed confidence in the integrity of the testing result. One of the ways to ensure the effectiveness of the RDT plan is by implementing the Six Sigma strategy. In this paper, the planning of developing RDT by using a structured Design for Six Sigma method, DMADV - Define, Measure, Analyze, Design and Verify is discussed. The DMADV steps will guide and outline the process from early stage until the end stage of developing the RDT plan. The plan will consider every process that is involved in the product design life cycle, including market or customer needs, reliability requirements, cumulative effects of use environment, life analysis distribution and tests equipment capabilities. The analysis tools used are translated from Critical-To-Quality (CTQ) to Critical-To-Reliability (CTR) requirements.

The problem of packing cylindrical parts into rectangular is complex and involves issues relating to geometry, and heterogeneity in the parts and in their nesting requirements. Presently, putting parts within the internal diameter of another part is accomplished ingenuity by operators who are unable to decide on the best nesting that maximizes the number of parts being nested. This paper addresses the nesting of parts within one another as subproblem. We describe the development of integer LP model that resembles the transportation problem for nesting of cylindrical parts into rectangular. The model considers rules that need to be followed in part nesting.

To survive worldwide competitions of research and development, decision-makers and researchers must detect the cutting-edge areas at the earlier stage. Now that computers enable us to process a large amount of data efficiently, bibliometric analysis can support decision-makers and researchers to invest into proper researches. We aim to find leading papers of the next generation with bibliometric approach. We analyzed time transitions of indicators, and found that in-degree centrality, communicability centrality and PageRank are useful as the indicators to detect emerging researches.

This research identifies the elements people consider important in their decision to adopt mobile internet TV. A theoretical framework was developed to describe adopting Internet TV via mobile device. The constructs used in the research model were Perceived Usefulness and Perceived Ease of Use, based on consumers' cognitive judgments of the service or the technology, from Technology Acceptance Model (TAM). The findings enable mobile operators to find the best way in developing current mobile data service and also preparing for mobile TV service which will be provided by TV broadcasting operator to serve 4G mobile technology in Thailand in the near future. Broadcasting TV service on 4G frequency to mobile user devices would be the origination of convergence between Telecommunications and Broadcasting.

In a telecommunications network architecture, BTS holds a very important role. In the event that causes disruption of BTS and BTS to be down, it will result in loss of potential revenue and lead to loss of consumer loyalty in the company. Hence the need for an effective method of treatment BTS and BTS efficient so that availability can be maintained properly. The method used in the treatment of BTS in this study is the RCM method (Reliability Centered Maintenance) to determine treatment priorities of existing equipment in the BTS based on vital functions and data destruction in order to obtain its value MTTF and MTTR, as well as LCC method (Life Cycle Cost) to determine the optimal number of sites crew for treatment BTS. By using the RCM method, the results of the determination of the critical components based on damage data, are obtained two set of equipment as critical components. They are generator and transmission module BCKM. Calculation and data processing of field data acquisition and secondary data the previous year, the value of the MTTF BCKM module is 1109.635 hours and MTTR BCKM 6,095 hours, while the value of the generator is 1647,373 hours MTTF and MTTR generator is 3.6 hours. While the number of site crew required in the BTS treatment based on the results of calculation and data processing with the LCC method, obtained the most optimal amount based on the cost is 4 site crews.

This contribution extends the results of an empirical study in the German plant manufacturing industry by a root cause analysis. Engineering plays a central role in the industrial value chain. Current assessments however do not consider its multiple impact in an adequate way. Since there is little literature about this topic - existing publications analyze performance from a technical-functional perspective or focus on design aspects - this study aims to evaluate performance criteria and challenges for performance assessments. 36 experts in the domain of plant engineering have been asked in a survey and personal interviews. Totally 13 challenges could be identified which oppose comprehensive assessments of engineering performance. A subsequent root cause analysis of these challenges - based on nine expert interviews - identified management practices, friction between technical and commercial functions in organizations and an unclear value proposition of engineering as underlying problems.

This paper investigates the scheduling of a rotationally arranged robotic cell with the Multi-Function Robot (MFR). The earlier known robotic study in this area assumed that the robot only moves the part between machines. We lift this assumption on robot tasks and assumed a special class of robots which is also able to perform a special operation in transit. The aim is to find a minimum cycle time for identical part production. Considering additive and constant travel-time, the distance between any two machines is varying or constant based on the robot acceleration/deceleration for incompact and compact cells. The lower bound of the cycle time is deduced to evaluate the optimality of two practical permutations namely uphill and downhill. It also identifies the regions where using a Multi-Function Robotic Cell (MFRC) is more economical than a Single-Function Robotic Cell (SFRC).

The concept of sustainable growth has been gaining ground to more intense competition in the business world. To contribute a more sustainable business, organizations should reconceive their value creation by inwardly focusing on economic, environmental and societal values simultaneously. As purchasing and supply management has been on the forefront of every business process, the decision making in this process should understand the various potential risks over a long time horizon in term of a product lifecycle perspective. In this view, the paper aims to develop strategic purchasing and supply management based on the Kraljic Model for building a long-term systematic thinking towards supply chain sustainability. The support of the model coupled with a lifecycle perspective would allow the organizations to design suitable long term purchasing strategies, contributing more sustainable values along an entire supply chain.
