支持大规模个性化需求描述的服务过程模型

传统的服务过程模型都是针对单个顾客的个性化需求,虽然能够满足顾客的个性化需求,但当大量的个性化需求到来时,需要为每一个需求建立独立的服务模型,导致整个服务过程模型的建立效率锐减、后期的维护成本增大。为此,提出了一种支持大规模个性化需求描述的服务过程模型(MPSPM),该服务过程模型首先将服务过程中的个性化需求按照功能、性能和价值三个方面进行总结和分类,并在此基础上给出基于可变点的满足大规模个性化需求的模型规范,以期在服务过程中使用最少的过程模型来满足大规模的顾客个性化需求。最后,以旅游服务为背景给出支持大规模的旅游个性化需求的服务过程模型,并开发出一款图形化建模工具来对该过程模型进行验证。

服务价值的若干性质初探

Service is defined as a provider-to-client co-production that creates and captures value while sharing risks. By collaborating people, resources and techniques from customers and providers together, a service system co-produces and delivers proposed values to all the participants of the service. As value holds a central position in lifecycle of services, it should be fully considered and aware of in full lifecycle of a service and it is very essential to be conscious of characteristics of values. This is the objective of this paper. Firstly, we make a classification on service values. Broad-sense value is produced either by transferring “things” between participants, or by improving some states of participants. Nine types of service values, including Economics Value, Product Value, Information Value, Resource Usage Value, Experience Value, Physical Value, Enjoyment Value, Social Impact Value, Knowledge and Skill Value, are roughly explained. Four means of value delivery between providers and customers are briefly discussed. However, most of current existing service model specifications (e.g., blueprint model, BPMN, SPC) emphasize particularly on service process modeling and values attract relatively little attentions among these methods. To remedy this defect, we put forward a new concept "Value Point" by which various types of values are closely connected with processcentric service models. Next, we do some preliminary discussions on characteristics of service value, including decompo- sability, composability, transitivity, transformation, and dependency. Connotation of each characteristic is elaborately discussed, followed by a set of real-world examples for illumination. Graphical representations of these characteristics are also presented to facilitate visual modeling of service values. Decomposability: implementation of one coarse-grained value is decomposed into implementation of a set of small values. Composability: multiple existing fine-grained values compose together to form a new coarse-grained value; Transitivity: a value is transferred from one participant to another without changing its modality; Transformation: one type of value is transformed into another type. Dependency: improvement on one value leads to improvement or deterioration of another value to a specific degree. Afterwards, based on these value characteristics, we briefly introduced a Value-Aware Service Engineering and Methodology (VASEM). Besides functional and performance transformation from initial requirements to final service systems, VASME emphasizes particularly on being aware of values in full lifecycle of a service, including value expression, value keeping, value adding, value realizing, value optimizing, and so on, based on above discussed characteristics of values. Result of this paper will provide some conducts to the research on service eco-system modeling, service engineering and methodology. It helps define objective of value delivery of a service system (i.e., value proposition), provide decision-making evidences to service modeling, support value-driven model transformation, and facilitate value-oriented service evaluation and optimization.
