This has prompted drilling departments to continuously look for ways to reduce their drilling costs and be as efficient as possible. A system called the Drilling Comprehensive Information Management and Application System (DCIMAS) is developed and presented here, with an aim at collecting, storing and making full use of the valuable well data and information relating to all drilling activities and operations. The DCIMAS comprises three main parts, including a data collection and transmission system, a data warehouse (DW) management system, and an integrated platform of core applications. With the support of the application platform, the DW management system is introduced, whereby the operation data are captured at well sites and transmitted electronically to a data warehouse via transmission equipment and ETL (extract, transformation and load) tools. With the high quality of the data guaranteed, our central task is to make the best use of the operation data and information for drilling analysis and to provide further information to guide later production stages. Applications have been developed and integrated on a uniform platform to interface directly with different layers of the multi-tier DW. Now, engineers in every department spend less time on data handling and more time on applying technology in their real work with the system.展开更多

Based on the practical research of consumers groups of college students, this paper analyzes the affecting factors on consumers＇ satisfaction among groups of college students, and also tests the affecting factors. Thus, the authors give their proposals on how to build the consumer online platforms in colleges and universities, and the prospects forecast on the campus online market.展开更多

An expectation-confirmation model of information systems （IS） continuance is adapted to construct a research model in online group-buying contexts. A total of 289 complete and valid responses were collected. Our findings contribute to academics and practitioners in two ways： Firstly, our respondents show that they are young （93% of the respondents＇ ages range between 19 and 28 years old）, female （88% of the respondents）, and thrifty （82% of the respondents＇ transaction amounts are below US$16）. Secondly, based on our results, price performance expectations have a direct impact on confirmation. In addition, in contrast to the IS continuance model （Bhattacherjee, 2001）, the effect of perceived usefulness on satisfaction is not supported. Thus, in online group-buying settings, confirmation is the key antecedent of satisfaction. Satisfaction and perceived usefulness are significantly associated with OGBP continuance intention. Consequently, in addition to offering a wide assortment of merchandise and a convenient online shopping experience to enhance customers＇ perceived usefulness of OGBP, OGBP managers should aim low-price marketing strategies at this female, young, thrifty and price-sensitive segment to transcend consumers＇ price expectations and attract consumers＇ continued intention to visit OGBP.展开更多

The organic CAS represents food quality without the use of synthetic chemicals to protect consumers＇ health. As a consequence, production costs and consumer prices have increased. The aim of this study is to analyze consumers＇ perception of the organic CAS label and how purchasing behavior for the product is influenced by converting the Fresh Milk Logo to the organic CAS certified label, which is based on contingent behavior analysis. This study adopts factor analysis to extract the perceptions and preferences of the respondents. In addition, the on-site Poisson model to revise the truncated and endogenous stratification and assess consumer welfare precision. The incremental consumer surplus for consumer consumed organic fresh milk is approximately NT$8,979.展开更多

In this paper, the main driving factors affecting the customer loyalty of a third party mobile payment service were chosen by combining with the actual situation of the third party mobile payment service and customer spending habits in China. The assumed relations between all affecting factors and the customer loyalty of a third party mobile payment platform were proposed, and a model for studying customer loyalty was established and also a conclusion was made through the questionnaire survey analysis data. Finally, suggestions on improving the loyalty of the customers of a third party mobile payment platform are presented.展开更多
