Abstract Customer Lifetime Value (CLV) is known as an important concept in marketing and management of organizations to increase the captured profitability. Total value that a customer produces during his/her lifetime is named customer lifetime value. The generated value can be calculated through different methods. Each method considers different parameters. Due to the industry, firm, business...

As opposed to contemporary activity-centric, process-aware information systems (PAIS), for which a multitude of concepts and implementations exist, there is only a very limited number of PAIS implementing data-centric, artifact-centric or object-aware approaches. This demo paper presents the implementation of a modeling environment for the object-aware approach to business process management. O...

Inflation for retirees is different from, and mostly higher than, the widely quoted macroeconomic inflation rate for the population. For example in the U.S. the Consumer Price Index (CPI) has a lesser known cousin called the CPI-E (for the elderly) in which the subcomponent weights are based on the consumption patterns of Americans above the age of 62. This suggests that Inflation Linked Bond F...

How to efficiently use energy is always one of most important issues in wireless sensor network(WSN) since the limited energy of sensor nodes. This paper presented a balancing energyaware sensor management protocol for WSN, namely BESM, based on PEAS(Probing Environment and Adaptive Sleeping). BESM allots more sleep time to those nodes that have less energy by two key means, i.e. negotiation st...

the parallel systems are special important types of coherent structures and have many applications in various areas.in this paper we consider a two-exchangeable-component parallel system for the generalized farlie-gumbel-morgenstern (generalized fgm) distribution. we study the reliability properties of the residual lifetime of the system under the condition that both components of the system ar...

Peer-to-peer (P2P) web caching has been studied recently as it can exploit local caches of peers for web caching without additional infrastructure. However, dynamic join/leave behaviors or local caching strategies of the peers due to their autonomy in a P2P network may limit the performance of P2P web caching. To overcome these limitations, we propose an effective directory-based P2P web cachin...

introduction: information management system is a formal approach to collect the necessary information in its due time for managers to facilitate decision-making, planning and management. medical records system which is closely associated with pieces of information and their true value can play an important role in health care organizations. the main objective of this study is to compare informa...

background: in process industries, production, storage, transportation, usage and disposal of chemicals are inherently dangerous and the risk of catastrophic accident occurrence is potentially high. to improve safety level in these industries, establishment of process safety management (psm) system is considered as the most effective measures. this study was conducted to determine the degree of...

Environment monitoring is one of the complex tasks in any industry. Sensor devices are used to handle the environment monitoring operations. Temperature, the sensor devices observe pressure and humidity values. The sensor networks are constructed with sensor devices. Battery power and bandwidth are the main limitations of the sensor networks. Managing the node lifetime and network lifetime are ...
