Process and product quality assurance are very important aspects in development of software. Process and product quality assurance monitor the software engineering processes and methods to ensure quality. It is the process of confirming and verifying that whether services and products meet the customer expectation or not. This research will identify general measures for the specific goals and i...

We consider the following continuous polling system: Customers arrive according to a homogeneous Poisson process (or a more general stationary point process) and wait on a circle in order to be served by a single server. The server is “greedy”, in the sense that he always moves (with constant speed) towards the nearest customer. The customers are served according to an arbitrary service time di...

described how the Internet enables a new supply chain paradigm, a push-pull paradigm that replaces the traditional push model. In the past, most companies operated by forecasting long-term demand, mass-producing inventories of product to fulfill the anticipated demand and then "pushing" the inventories on to the customer. The disadvantage of the push model is that production decisions are based...

The research project examines expectations as well as organizational and technological cognitive beliefs influencing a company’s intention to continue using on-demand enterprise systems in the post-acceptance phase. Expectation-confirmation theory from behavior literature is integrated with Delone & McLean’s model of IS success to theorize a model of IS continuance on company level. The decisio...

This paper analyzes customer product-choice behavior based on the recency and frequency of each customer’s page views on e-commerce sites. Recently, we devised an optimization model for estimating product-choice probabilities that satisfy monotonicity, convexity, and concavity constraints with respect to recency and frequency. This shape-restricted model delivered high predictive performance ev...

This research article reports the findings of a survey-based comparative study on current IT utilization by 3PL firms in the United States (US) and the People’s Republic of China (PRC). The findings reveal that in general the level of IT utilization and IT focus of 3PL firms in the PRC are lower than that of their counterparts in the US. This may result in a bigger gap between customer expectat...

There are several software process models that have been proposed and are based on task involved in developing and maintaining software product. The large number of software projects not meeting their expectation in terms of functionality, cost, delivery schedule and effective project management appears to be lacking. In this paper, we present a new software fusion process model, which depicts ...

Web engineering becomes increasingly important in the last years. WEB and audio services have to provide the best services possible. To achieve this goal, they have to find out what the customers are doing without altering their privacy. This paper presents two classes of models, mathematical and learning models, and two possible ways to manage and build adaptative menus. These methods are grav...

Most online auction platform providers (OAPPs) agree that the majority of their profits comes from users, i.e., their buyers and sellers. The major concern of OAPPs is how to gain and lock in users in order to maintain and enhance a competitive edge. Customer switching is one of the primary problems of all companies, including OAPPs. This study focused on online auction sellers and attempted to...
