This paper presents the results of the supplier selection process conducted by a Nigerian service sector organization. One organization was used as a case study whereby data collection involved an action research approach; the data was then subject to statistical analysis via the SPSS Statistics software package. In total, 185 potential suppliers were assessed. Several statistically significant differences were also found between those suppliers that met the minimum requirements and those that did not as well as between organizations that offered products and organizations that offered services.

Many works have been done on the product flow of the supply chain whereas there is a little research works on the financial aspect of the supply chain. Moreover, bullwhip effect like lead time is usually considered on the product flow of the supply chain and no literatures review this effect on the cash flows. In this paper, the flow of cash in a supply chain is considered from the manufacturer point of view who receives money from its customers and makes payment to the suppliers. A stochastic model to maximise firm's profit and to And the best strategy of paying payment is developed. Furthermore, we investigate the effect of late payment on the Arm's profit within the supply chain. Finally, the effect of logistic bullwhip on the cash flow and firm's profit is investigated.

The proliferation of mobile banking is creating increased opportunities for seamless businesses processes. The advent of Near Field Communication (NFC) could facilitate the future of mobile payment. Even though NFC has been adopted in several countries, this new technology has not been adopted by individuals in Macau, where the tremendous economic growth is greatly dependent on the gaming industry. This paper presents a study on consumers' attitudes towards adoption of NFC enabled mobile payment technology in Macau. By using Technology Acceptance Model (TAM) and related literature, an evaluation model is designed to analyze users' adoption of NFC in Macau. The results reveal academic and practical implications for future development and implementation of NFC in Macau.

In recent days it is necessary to maintain continuous surveillance of underwater transmission lines or oil pipelines. For such purpose, we require an underwater vehicle rover capable of tracking these wires or pipelines and detect the fault if it occurs. For this purpose we have designed an intelligent quad leg rover. Image processing as a key deployed for tracking and tracing the fault or damage. Hough's Transformation is used for the detection of the wire, and threshold levels were also set of the underwater environment for vehicle to focus only on wire. For tracking the transmission lines and proper navigation, we have used a masking technique. The system is implemented on Raspberry pi (Broadcom BC2835) as well as Intel Core Processor T7250 to improve and analyze the performance in terms of size and mobility. The results presented in this paper are simulated on Intel T7250 processor and on raspberry pi. It helps in evaluating the response time of the raspberry pi when compared to any other processors in terms of computation and robustness.

This paper aims to address two challenging questions: "What are the bases on which online users choose to use and/or mine their cryptocurrency?" and "Which factors strongly affect the coin's popularity and value?" We try to answer these two questions for eight chosen cryptocurrencies by conducting an online survey. Results obtained from the online survey indicate that more than half of the participants believe that the currency name and logo affect the choice of using and/or mining a cryptocurrency. Moreover, the majority of the participants stated the ease of mining, having strong, fun and large community along with anonymity, privacy, and the currency's value, popularity, potential and technology as advantages of the currencies they choose to use and/or mine. These results help in observing the people behavior and predicting how successful and promising a cryptocurrency might become in the future.

The manufacturing of different types of cylindrical parts requires loading of parts into baskets for heat treatment operation. This loading process is complex and involves issues relating to geometry, and heterogeneity in the parts and in their processing requirements. The parts loaded for heat treatment often do not utilize the available capacity adequately because layer-loading is accomplished by operator ingenuity. Productivity in heat treatment operation can be increased by improving utilization, which is determined by the loading process. This paper describes the development mathematical model using mixed integer nonlinear formulation for loading of cylindrical parts into baskets. The mathematical modeling considers the exact location of parts to be loaded on the layers with the primary objective of minimizing unutilized volume of the baskets.

Technology developments have made it possible to discover and harvest oil from deepwater reserves, however, maintaining asset integrity of deepwater facilities is not without challenges. This is due to the unique site characteristics and uncertainties in predicting future performances. Based on a literature survey as well as interviews with industrial experts, this paper investigates challenges in the integrity management of deepwater petroleum production assets. A workflow is proposed as a guideline to establish an integrity management plan. In addition, an industrial service strategy will be discussed as an alternative solution to deepwater challenges.

Capturing security and privacy requirements in the early stages of system development is essential for creating sufficient public confidence in order to facilitate the adaption of novel systems such as the Internet of Things (IoT). However, security and privacy requirements are often not handled properly due to their wide variety of facets and aspects which make them difficult to formulate. In this study, security-related requirements of IoT heterogeneous systems are decomposed into a taxonomy of quality attributes, and existing security mechanisms and policies are proposed to alleviate the identified forms of security attacks and to reduce the vulnerabilities in the future development of the IoT systems. Finally, the taxonomy is applied on an IoT smart grid scenario.

The purpose of this paper is to identify new potential research areas for health care as part of the service sector. To evaluate how supply chain management (SCM) research can support this sector, supply chain principles identified by a literature review will be matched with challenges and trends identified in a cross-industry sector semi-structured interview series. Finally, a set of promising principles is identified and the potential to further analyze their application e.g. in the health care industry suggested as an area for future research.

The effects of globalization have caused a continuous increase of competition intensity within the tool and die industry. Thus European tool shops have access to emerging markets but in the same time they have to face new competitors with lower factor costs. Furthermore customer requirements have changed. New customer requirements lead to derivatization and decreasing product lifecycles. The demographic change results in limited availability of skilled and experienced employees which especially affects know-how intensive industries as the tool and die industry. In sum all factors force European tool shops to aim for a fast, efficient and cost minimal manufacturing process. This aim is only achievable by a capable employee and technology allocation. This paper presents a methodology developed by the Laboratory for Machine Tools and Production Engineering (WZL) of RWTH Aachen University, which shows an appropriate resource allocation regarding employees and technologies to enable an optimal value creation process.
