Service is provided through the application of service systems, which consist of clients and service providers that interact to co-produce value. However, because of the complexity of the management and modeling of people, technologies, knowledge, activities, processes, intentions, organizations, and wide range of types of service systems, formal representation and modeling of service systems is still in its initial stage. There is a need for a clearer understanding of service systems and the capabilities required for excellent service operation and continuous service innovation. The objectives of this study are three-fold: (1) to understand the required capabilities of service systems, (2) to examine service systems using different classifications, and (3) to explore the capabilities of service systems. This study establishes a comprehensive understanding of service systems, service components, different classifications of service systems, and required capabilities of service systems through qualitative media analysis and multiple case studies. The findings of this study are: (1) Service systems components are organized into four major parts: service provider, service client, service controller, and service supporting components. (2) Ten service systems classifications are constructed through the six classifying dimensions of customer participation, communication time, information richness, intimacy, customization, and delivery by ICT (information and communication technology). (3) Five service systems capabilities: integration, customization, technology optimizing, innovation, and learning, are proposed. (4) Six types of service systems are found when exploring the capabilities of service systems. Each type of service systems acts differently to acquire different capabilities. (5) The relationships between classifying dimensions and capabilities are delineated. Capabilities can be influenced by different classifying dimensions This study provides a structural framework for organizing business opportunities, as well as management implications for service systems management.

The transient analysis of large-scale systems is often difficult even when the systems belong to the simplest M/M/n type of queues. To address analytical difficulties, previous studies have been conducted under various asymptotic regimes by suitably accelerating parameters, thereby establishing some useful mathematical frameworks and giving insights into important characteristics and intuitions. However, some studies show significant limitations when used to approximate real service systems: (i) they are more relevant to steady-state analysis; (ii) they emphasize proofs of convergence results rather than numerical methods to obtain system performance; and (iii) they provide only one set of limit processes regardless of actual system size. Attempting to overcome the drawbacks of previous studies, this dissertation studies the transient analysis of large-scale service systems with time-dependent parameters. The research goal is to develop a methodology that provides accurate approximations based on a technique called uniform acceleration, utilizing the theory of strong approximations. We first investigate and discuss the possible inaccuracy of limit processes obtained from employing the technique. As a solution, we propose adjusted fluid and diffusion limits that are specifically designed to approximate large, finite-sized systems. We find that the adjusted limits significantly improve the quality of approximations and hold asymptotic exactness as well. Several numerical results provide evidence of the effectiveness of the adjusted limits. We study both a call center which is a canonical example of large-scale service systems and an emerging peer-based Internet multimedia service network known as P2P. Based on our findings, we introduce a possible extension to systems which show non-Markovian behavior that is unaddressed by the uniform acceleration technique. We incorporate the denseness of phase-type distributions into the derivation of limit processes. The proposed method offers great potential to accurately approximate performance measures of non-Markovian systems with less computational burden.

This study explores how managers are coping within a changing public healthcare service context and how the role of service managers and the nature of Management Development are being transformed. With the public healthcare sector in the UK facing complex challenges including financial constraint and increasing service demand, it is inevitable that collaborative partnership working and service integration are viewed as a means of addressing such challenges. Using the views and experiences of service managers from Scottish Community Health Care Partnership cases, the study highlights the experiences of managers in relation to partnership working and service integration and explores the potential implications of this for managerial learning, training and development. The research evidence establishes the importance of changing roles, responsibilities and relationships for managers in a changing healthcare service environment and takes on board a Service-Dominant approach and propositions from New Public Governance theory to explain these and to address attendant issues. Specifically, the challenges surrounding the learning, training and development of managers in an increasingly integrated services environment are explored and reconceptualised through a Services-as-Systems approach. The outcomes of this study allow for a better understanding of the changing nature of work that managers do and attempts to reframe Management Development in such a context for the future.
