e-CLV: a modelling approach for customer lifetime evaluation in e-commerce domains, with an application and case study for online auctions

Abstracte-Commerce companies acknowledge that customers are their most important asset and that it is imperative to estimate the potential value of this asset.In conventional marketing, one of the widely accepted methods for evaluating customer value uses models known as Customer Lifetime Value (CLV). However, these existing models suffer from two major shortcomings: They either do not take into account significant attributes of customer behavior unique to e-Commerce, or they do not provide a method for generating specific models from the large body of relevant historical data that can be easily collected in e-Commerce sites.This paper describes a general modeling approach, based on Markov Chain Models, for calculating customer value in the e-Commerce domain. This approach extends existing CLV models, by taking into account a new set of variables required for evaluating customers value in an e-Commerce environment. In addition, we describe how data-mining algorithms can aid in deriving such a model, thereby taking advantage of the historical customer data available in such environments. We then present an application of this modeling approach—the creation of a model for online auctions—one of the fastest-growing and most lucrative types of e-Commerce. The article also describes a case study, which demonstrates how our model provides more accurate predictions than existing conventional CLV models regarding the future income generated by customers.

Flexible modeling tools for pre-requirements analysis: conceptual architecture and research challenges

A serious tool gap exists at the start of the software lifecy-cle, before requirements formulation. Pre-requirements analysts gather information, organize it to gain insight, en-vision possible futures, and present insights and recom-mendations to stakeholders. They typically use office tools, which give great freedom, but no help with consistency management, change propagation, or information migration to downstream tools. Despite these downsides, office tools are still favored over modeling tools, which are constrain-ing and difficult to use. We introduce the notion of flexible modeling tools, which blend the advantages of office and modeling tools. We propose a conceptual architecture for such tools, and outline research challenges to be met in realizing them. We briefly describe the Business Insight Toolkit, a prototype tool embodying this architecture.

Using tagging to identify and organize concerns during pre-requirements analysis

Before requirements analysis takes place in a business context, business analysis is usually performed. Important concerns emerge during this analysis that need to be captured and communicated to requirements engineers. In this paper, we take the position that tagging is a promising approach for identifying and organizing these concerns. The fact that tags can be attached freely to entities, often with multiple tags attached to the same entity and the same tag attached to multiple entities, leads to multi-dimensional structures that are suitable for representing crosscutting concerns and exploring their relationships. The resulting tag structures can be hardened into classifications that capture and communicate important concerns.

Industrial Cyber-Physical Systems – iCyPhy

ICyPhy is a pre-competitive industry-academic partnership focused on architectures, abstractions, technologies, methodologies, and supporting tools for the design, modeling, and analysis of large-scale complex systems. The purpose of this partnership is to promote research that applies broadly across industries, providing the intellectual foundation for next generation systems engineering. The focus is on cyber-physical systems, which combine a cyber side (computing and networking) with a physical side (e.g., mechanical, electrical, and chemical processes). Such systems present the biggest challenges and biggest opportunities in several critical industrial segments such as electronics, energy, automotive, defense and aerospace, telecommunications, instrumentation, and industrial automation. The approach leverages considerable experience designing complex artifacts in the semiconductor, embedded systems, and software industries, and major recent advances in algorithmic techniques for dealing with complexity. This consortium adapts and extends these techniques to handle the fundamentally different challenges in largescale cyber-physical systems.

An algorithm for identifying the abstract syntax of graph-based diagrams

Diagrams play a key role in the information systems domain. However to be meaningful, the diagrams are understood by interpreting visual cues in specific, conventionalized ways, termed conceptual models. One of the major pain points of conceptual models, specified as visual languages, is the inability to capture these visual languages effectively in conventional modeling tools. Instead, conceptual models are drawn using drawing tools and sometimes even by hand. We propose an automatic procedure to derive the syntactic building blocks of graph-based conceptual models. This high-level specification of the visual language can then serve as input for the automatic construction of syntax-aware diagram editors. Our aim is to achieve minimum effort on the part of the users when they eventually work with the graphical editor to produce a new diagram using the proposed syntax.

Business insight toolkit: Flexible pre-requirements modeling

Pre-requirements analysis requires modeling tools with unprecedented flexibility. The Business Insight Toolkit (BITKit) is a prototype of a new kind of modeling tool, aimed at offering the flexibility of office tools along with many of the advantages of modeling tools.

A Top-Down Approach from Service Centers to Business Processes

Business service centers (BSC) design a framework for defining non-overlapping, independent, reusable, cost-effective business centers that provide business services. Business services define the way service centers interact and exchange information and assets to achieve business goals. BSC modeling offers many advantages over traditional techniques, such as reuse, simplicity, implementation autonomy, and responsiveness. On the other hand, defining and modeling business processes (BP) is a critical factor in improving business performance. We propose a top-down approach from the business level to the operational level, taking advantages of both BSC and BP approaches. Using the guidelines described in this framework, business designers can use both BSC and BP techniques to provide an end-to-end view of business operations. In a climate of constant and unpredictable change, synergy between process thinking and service center thinking becomes essential to the success of enterprises.

A Method for Service Center Architecture Based on Industry Standards

Component Business Modeling (CBM) designs a framework for defining non-overlapping, independent, reusable, cost-effective business components or service centers that provide business services. CBM is gaining broad acceptance in todays marketplace. On the other hand, compliance with industry standards is becoming an imperative in todays enterprises. We propose a bottom-up method for deriving business components from industry standards, based on the artifact-centric approach. In a climate of constant and unpredictable change, alignment between service centers and industry standards becomes essential to the success of enterprises.

Calculating the Business Importance of Entities in a Service-Oriented Enterprise

Component business modeling (CBM) serves as a powerful analytical framework for reasoning about the business as a set of business components that collaborate through the provision and consumption of business services. This paper proposes and illustrates a method to calculate the relative importance of the entities that make up a componentized enterprise architecture. The proposed method includes a formal definition of the importance of each entity in the business architecture calculated from the high level business values.

A top-down approach to aligning business service centres with business processes

Business Service Centres (BSCs) design a framework for defining non-overlapping, independent, reusable, cost-effective business centres that provide business services. Business services define the way service centres interact and exchange information and assets to achieve business goals. BSC modelling offers many advantages over traditional techniques such as reuse, simplicity, implementation autonomy and responsiveness. On the other hand, defining and modelling Business Processes (BPs) is a critical factor in improving business performance. We propose a top-down approach from the business level to the operational level, taking advantages of both BSC and BP approaches. Using the guidelines described in this framework, business designers can use both BSC and BP techniques to provide an end-to-end view of business operations. In a climate of constant and unpredictable change, synergy between process thinking and service centre thinking becomes essential to the success of enterprises.
