A Value

In recent years, crossover services have attracted wide attention as an emerging service mode in the modern service industry. Crossover services can offer values that cannot be provided by single-domain services, and they usually need to cross the boundaries of domains, organizations, and processes, which puts forward more challenges for requirements modeling and analysis under the crossover scenarios. Given the characteristics of crossover services, the authors propose a value-driven meta-model framework from multiple viewpoints to support the requirements analysis of crossover services, which consists of three parts: a value network, a goal network, and a service network. Based on the proposed meta-model framework, a value-driven crossover service modeling tool is developed to help requirements analysts in requirements analysis and design, and a case study is presented to illustrate the usage of the proposed approach. Finally, we evaluate our methods and tools using a controlled experiment, and the experimental results show the effectiveness of the approach.

This chapter addresses service value networks as a key pathway to establishing and likely retaining future strong competitive positioning within a service industry sector. A service value network may be defined as “the flexible, dynamic delivery of a service, and/or product, by a business and its networked, coordinated value chains (supply chains and demand chains working in harmony); such that a value-adding and target-specific service and/or product solution is effectively, and efficiently, delivered to the individual customer in a timely, physical, or virtual manner.” The service value network offers a future pathway for a business to develop its e-supply chain systems. It captures the contacting customer, and integrates the customer’s (virtual e-customer, virtual e-business customer, or physical customer) demands via its virtual or Web site interface into its integrated downstream service networks, seeks solutions, and delivers the appropriate business solutions back to the customer. Value-enhanced business encounter solutions are readily deliverable for targeted customers. The procedure to research and develop a service value network is described.

Requirements Modeling

Inconsistent specification are an inevitable intermediate product of a service requirements engineering process. In order to reduce requirements inconsistencies, we propose PASER, a Pattern-based Approach to Service Requirements analysis. The PASER approach first extracts the process information from service documents via natural language processing (NLP) techniques, then uses a requirements modeling language – Workflow-Patterns-based Process Language (WPPL) — to build the process model. Finally, through matching with workflow patterns, the inconsistencies in service requirements are identified and resolved by checking against a set of checking rules. We have conducted a preliminary experiment to evaluate it. An ATM service case study is presented as a running example to illustrate our approach.

This paper presents a case study of requirements elicitation for the development of computational support tools at an automotive OEM. The challenges presented in the requirements development necessitated the fusion of three distinct requirements elicitation approaches: traditional design, participatory design, and use case modeling through UML. The findings suggest that a single mode of operation is not sufficient and that to capture the requirements, it is preferred to borrow tools and methods from multiple domains. This case study serves as a broader motivation for a systematic development of engineering requirements modeling and analysis methods.

Logic System

UML is now popularly applied as a requirements modeling language for software system analysis and design, and the dynamic behaviors of system are described in UML behavioral model. As the UML model suffers from lack of well-defined formal semantics, it is difficult to formally analyze and verify the behavioral model. The paper presents a method of UML behavioral model verification based on Description Logic system and its formal inference. The semantics of UML behavioral models is divided into static semantics and dynamic semantics, which are formally specified in OWL DL ontology and DL-Safe rules. To check the consistency of the behavioral models, the algorithms are provided for transforming UML behavioral models into OWL DL ontology, and hence model consistency can be verified through formal reasoning with a DL supporting reasoner Pellet. A case study is provided to demonstrate applicability of the method.

The island marble butterfly (Euchloe ausonides insulanus), thought to be extinct throughout the 20th century until re-discovered on a single remote island in Puget Sound in 1998, has become the focus of a concerted protection effort to prevent its extinction. However, efforts to “restore” island marble habitat conflict with efforts to “restore” the prairie ecosystem where it lives, because of the butterfly’s use of a non-native “weedy” host plant. Through a case study of the island marble project, we examine the practice of ecological restoration as the enactment of particular norms that define which species are understood to belong in the place being restored. We contextualize this case study within ongoing debates over the value of “native” species, indicative of deep-seated uncertainties and anxieties about the role of human intervention to alter or manage landscapes and ecosystems, in the time commonly described as the “Anthropocene.” We interpret the question of “what plants and animals belong in a particular place?” as not a question of scientific truth, but a value-laden construct of environmental management in practice, and we argue for deeper reflexivity on the part of environmental scientists and managers about the social values that inform ecological restoration.

This study investigated how young teenagers, as members of a strong religious organization, dealt with the school situation and the encounter with mainstream culture taking place at school during the final years in Swedish primary school (age 13–15 years). The purpose was to explore possible strategies that members of a minority group, in this case the Jehovah’s Witnesses, developed in order to deal with a value system differing from that of the group. We interviewed eleven former members of the Jehovah’s Witnesses about their final years in compulsory Swedish communal school. The ages of the interviewees ranged between 24 and 46 years, and the interviewed group comprised six men and five women. Nine of the eleven interviewees had grown up in the countryside or in villages. All but two were ethnic Swedes. The time that had passed since leaving the movement ranged from quite recently to 20 years ago. The results revealed three strategies; Standing up for Your Beliefs, Escaping, and Living in Two Worlds. The first two strategies are based on a One-World View, and the third strategy, Living in Two Worlds, implies a Two-World View, accepting to a certain extent both the Jehovah’s Witnesses outlook as well as that of ordinary society. The strategy Standing up for Your Beliefs can be described as straightforward, outspoken, and bold; the youngsters did not show any doubts about their belief. The second subgroup showed an unshakeable faith, but suffered psychological stress since their intentions to live according to their belief led to insecurity in terms of how to behave, and also left them quite isolated. These people reported more absence from school. The youngsters using the strategy Living in Two Worlds appeared to possess the ability to sympathize with both world views, and were more adaptable in different situations.
