Portfolio Selection For Service Systems

The deregulation of the global telecommunication industry has seen a change in the business and operational environment in which services are deployed and managed. The requirements have intensified to provide a management framework for telecommunication networks and services across multiple technology domains and using multiple management technologies. This paper describes an integrated TMN service management architecture that provides an environment for different service management functions and different management domains to be integrated. To further substantiate this architecture, a system was built to demonstrate the integration concepts. The research and development work reported in this paper focuses on the following two aspects of integration: first the integration between TMN network and service management functions; and next the integration between different service management functions. A proof of concept system was developed to demonstrate such integration. It consists of the following components: Generic service ordering and provisioning; connection management based on a generic network model concept; and service management based upon service level agreement management and customer service management concepts. This paper reports this work and the experiences gained from this research.

This paper presents a Capability Ontology (CapOnt) and a rule-based reasoning mechanism, which support service management within adaptable service systems. The ontology concepts comprise capability types, capability parameters and service management functions related to capabilities. Capability parameter values can be defined by constraints on other capability parameters. The service management functions included in the ontology are Capability Administration, Capability Configuration, Capability Allocation and Capability Performance Diagnosis. The service management functions are defined by rules consisting of constraints and management actions. The ontology concepts are represented in OWL (Web Ontology Language) and OWL/XDD (XML Declarative Description Language) - a rule-oriented knowledge representation. An intelligent conference room example with simulation results, that demonstrates the CapOnt and the rule-based reasoning, is also presented.

The existing Service Creation Environments (SCEs) speed up the design of IN service logic, but the whole process of service creation is still relatively long. Very limited support for the service specification and validation provided by the SCEs is one of the reasons. This paper presents a graphical simulation environment called INAP Wrapper that supports IN service prototyping and validation at the early stages of service creation. INAP Wrapper is built around the standard SDL specification of the INAP CS1/2 protocol developed by ETSI. The ETSI specification has been extended by the SDL models of switched network, service management, and service control function. Service validation is based on the SDL simulation capabilities of Telelogic Tau tool suite and the animation capabilities of the INAP Wrapper GUI. The paper presents the INAP Wrapper environment and its industrial applications.KeywordsService LogicBlock TypeService CreationService ValidationService PrototypeThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.

Component technology is only available for business-oriented quality of service (QoS) management functions, can not satisfy the QoS requirements of soft real-time applications areas such as the multimedia and Web services. For real-time guarantee and improving resource utilization needs, this paper presents a real-time scheduling model for soft real-time component-oriented systems. First, the task model, component QoS specifications, resources container, resources container manager, and scheduler-related factors and their mutual relations are described. Second, the method for adding real-time mechanism to the component system is given. Finally, the scheduling algorithm is extended based on this model, and the resource container management algorithms are given, including access control algorithm, out of control algorithm, and QoS negotiation algorithm. The model meets the real-time requirements of applications and improves the system resource utilization together.

SUMMARYWireless mesh networks (WMNs) as community‐ and city‐wide type networks are required to extend their capability to offer real‐time multimedia services. While technologies exist to support quality of service (QoS) at node level, we propose here a network‐wide multi‐step solution to manage and offer QoS across a WMN. From a provider perspective, the provisioning and fulfillment of QoS‐based services fall under the realms of service management, network and traffic engineering functions. We describe the relevant functions required to design, implement and operate a WMN for providing a qualitative QoS to end‐users. Our proposed solution considers network planning aspects, including node placement, node clustering and frequency assignments, route discovery between ingress–egress points and appropriate QoS provisioning across the network. Route‐level QoS provisioning is defined as the process of allocating resources to the nodes along the identified routes to meet a priori known aggregated traffic demands in order to satisfy the QoS requirements for different types of application. Simulation and experimental tests are conducted to validate the correct behavior of processes/algorithms and to access the solution in achieving QoS for aggregate user traffic.

Deriving from approaches of PSL, service ecosystems, complexity and conflicts, this article proposes a framework of complex public service systems for understanding public service management. As drivers of service systems transformation, conflicts foster understanding of value co-creation, its underlying challenges, and service systems transformation. In the empirical study of youth service development initiative, the organizational actors’ conflicts in understanding the service users’ needs, value, the roles of actors, and the service system transformation were identified. In conclusion, the conflicting institutional arrangements in multi-actor, complex, and overlapping service systems’ settings both maintain and disrupt the value co-creation and service systems.

This is a conceptual article written to apply I-S-P-A-R model which was presented in 2009 by research scholars Maglio, Vargo, Caswel and Spohrer on the Mentoring in Service Dominant Logic (SDL) perspective. The author has taken a deep insight of mentoring which is a part of training and development: a function of the Human Resource Management in Good Dominant Logic (GDL) perspective. For this research, a wide range of literatures is reviewed and many disciplines have been explored which include mentoring roles, need, responsibilities, and context. Here, it is worthy to mention that mentoring and supervision are two different terms and both have different roles, too. Roles of supervisors are: boss, teacher, evaluator, expert and counselor; whereas mentoring consisted of assisting, befriending, guiding, advising and counseling. In service science, all the service systems do not fulfill the requirement to be a service system. There is also presented I-S-P-A-R which stands for Interact-Serve-Propose-Agree-Realize model of service system interactions episodes. This model is applied on mentoring in SDL perspective. At the end of this article, a conclusion is drawn and areas for further research have been mentioned.

MPLS technology has recently been widely adopted, not only in large-scale IP backbones, but in metro and enterprise networks as well. Among the merits of MPLS, effective and efficient support of TE (traffic engineering) and VPN (virtual private network) services is the most influential factor that has facilitated the diffusion of the technology. However, although MPLS itself has become a currently operational technology, issues regarding the management of various services that are built on top of individually operating MPLS capable network elements have not been well identified or solved. These service level management issues arise, not only under heterogeneous conditions, but even when the target network is homogeneously composed. The paper discusses the requirements and architectural aspects of an integrated service management system for MPLS TE and VPN services. The discussion encompasses fault and performance management issues and information models which should be flexible to support newer services that can be rendered by merging TE, VPN, and QoS technologies. We also examine performance, fault tolerance, and scalability issues that cannot be neglected when such systems are deployed in a real-world environment.

This study aims to analyze information technology service management (IT Service Management) in the product ordering process through the Klik Indomaret application developed by PT Indomarco Prismatama. As consumer demand for fast and efficient online shopping services increases, the company is required to provide a reliable, responsive, and user-friendly IT service system. This research employs a qualitative approach, using data collection techniques such as interviews, observations, and document analysis. The analysis is based on the ITIL (Information Technology Infrastructure Library) framework to evaluate the effectiveness of service management in supporting core business processes. The findings indicate that although the Klik Indomaret application has positively contributed to streamlining the ordering process and improving customer satisfaction, several challenges remain, such as delays in stock data updates, system disruptions, and limited integration among IT services. Recommendations include enhancing system monitoring, optimizing the service desk, and strengthening incident management strategies. These findings are expected to serve as a foundation for the future development of more robust IT services.

Service oriented architecture is a popular service business that processes client application software and stores client data. Cloud computing centres provide a collection of services on a for-use basis. Before discussing the complete cloud infrastructure and service management, it is important to understand the concept of cloud computing in more detail, including its characteristics, benefits, services, and deployment models. The cloud computing services providers keep track of the actual customer usage with a metered service system. They then provide billing and chargeback information for the Cloud resource used by each consumer with a detailed usage file available for customer inquiry. Operating a corporate data centre also involves employing and training a variety of technical personnel. Among these are operational personnel for running the applications, supporting the networks, and proving help desk support to end-user customers who access the data centre to make use of the offered computing services.
