Service Exchange or Major Overhaul. Which Philosophy to Implement for Gas Turbine

Maintenance costs and machine availability are two of the most important concerns to gas turbine equipment owner. Therefore, a well thought out maintenance program that reduces costs while increasing equipment availability should be instituted. The correct implementation of planned maintenance relying on preventive maintenance optimization through perfect inspection frequency and scope provides direct benefits in the avoidance of forced outages, unscheduled repairs, and downtime. Major overhaul is carried out for each gas turbine every 48,000 firing hours which costs around 1 M USD for each engine and with more than 8 months unavailability for the unit. To increase equipment availability and enhance cost and time efficiency, alternatives approaches were evaluated including Service Exchange of gas turbines. It is found that service exchange is the best option for optimizing time and cost of overhaul of such engines. This paper is written to improve Major Overhaul practice for existing Gas Turbines from ongoing practice of routine major overhaul including engine strip down, inspection and repair to Service Exchange of Gas Generator and Power Turbine every 48,000 firing hours.

How Has Digitalisation Influenced Value in the Music Market?

This paper focuses on how digitalisation has influenced actors’ value determination and value creation in the Swedish music market. It draws on the service-dominant logic (SDL) and the service ecosystem perspective to conceptualise value as co-created through the integration of resources by multiple actors in service exchange, enabled and constrained by institutions and institutional arrangements. Empirically, we draw on a qualitative study of the digitalisation of the Swedish music market that consists of fifty-two interviews with various actors. The findings suggest that digitalisation has influenced service engagement and consequently value creation and determination for various actors, and especially for consumers and producers. This paper contributes by integrating SDL and the service ecosystem perspective into music business research in a novel way to promote a deeper understanding of value, value determination, and value co-creation. This paper also contributes to SDL by suggesting that both value-in-exchange and value-in-use are important aspects of value determination and value co-creation.

The Effect of Thickness-Based Dynamic Matching Mechanism on a Hyperledger Fabric-Based TimeBank System

In a community with an aging population, helping each other is a must society function. Lacking mutual trust makes the need for a fair and transparent service exchange platform on top of the public service administration’s list. We present an efficient blockchain-based TimeBank realization with a newly proposed dynamic service matching algorithm (DSMA) in this work. The Hyperledger Fabric (or Fabric in short), one of the well-known Consortium Blockchains, is chosen as our system realization platform. It provides the identity certification mechanism and has an extendable network structure. The performance of a DSMA is measured by the waiting time for a service to get a match, called the service-matching waiting time (SMWT). In our DSMA, the decision as to whether a service is to get a match or wait for a later chance depends dynamically on the total number of contemporarily available services (i.e., the thickness of the service market). To better the proposed TimeBank system’s service quality, a Dynamic Tuning Strategy (DTS) is designed to thicken the market size. Experimental results show that a thicker market makes on-chain nodes have more links, and in turn, they find a match easier (i.e., consume a shorter SMWT).

Integrated security for data transfer and access control using authentication and cryptography technique for Internet of things

The entire world is running behind the smart technology to accomplish the daily needs in a smart way such as smart farming, smart irrigation system, smart transportation system, smart medical management, handling of smart home appliances, smart security, etc. Smart technology is the soul property of internet services and accessing data from virtual servers, which raises the alarm of security vulnerability and threats. In recommended system we have focused on application layer security which are concerned with application interface and queue manager for service exchange. As application layer is the closest to end user and produces the big threat to the application platform it motivates us to recommend strong multilevel security system to identify the different activity of handlers and identify their roles to enroute of accessing confidential data services. Subsequently, our work is to assure that every user should have an authentication key with specific privileges to get the desired information. In focus, we see the security management by integrating the Kerberos authentication protocol with honey encryption technique to provide strong multilevel security system.

Influence of country of origin and type of information exchanged on consequences of offshore service sentiment

PurposeThis research extends existing services offshoring literature by investigating how the type of information exchanged, technical support or personal billing, in conjunction with country-of-service-origin (COSO) influences consumer likelihood to react negatively (boycott issue importance, NWOM, perceived service quality) to an offshore service exchange.Design/methodology/approachStructural equations modelling is employed to assess relationships among constructs when country of service origin (New Zealand and the Philippines) and type of service provided (technical support and personal billing services) are varied. Using a scenario-based experimental design we collected 337 responses from a consumer panel across Australia.FindingsResults indicate that both COSO and type of information exchanged affect service sentiment. Overall, consumers feel more negative and more likely to punish a company for offshoring to culturally dissimilar countries such as the Philippines than to culturally similar ones such as New Zealand. However, consumers were more concerned with personal billing services provided from offshore providers than technical support, regardless of COSO.Practical implicationsPractitioners need to understand customer sentiment about services offshoring in general as well as the relationship between service type and country of service origin when designing the global service supply chain.Originality/valueThis study extends theory by applying a multi-dimensional portfolio perspective in examining customer sentiment of offshore services. Understanding the underlying bases of customer concerns and how companies can mitigate negative perceptions allows firms to better manage service offshore strategy.

Customer responses to employee deviance: A conservation of resources perspective

This study aspires to examine how customers respond to two forms of frontline employee deviance (i. e., customer-oriented deviance, COD, and customeroriented misbehaviour, COM) during a specific service exchange. Drawing on the conservation of resources theory, COD and COM are viewed as resources and demands of customer performance during their exchanges with employees. Five customer responses are examined, namely encounter satisfaction, and employee-oriented citizenship behaviour, customer dysfunctional intentions, customer citizenship behaviour towards the organisation, and brand advocacy. To gain insights into these issues, an experimental design is adopted, which manipulates the two forms of deviance along with two boundary conditions: the extent to which the problem the customer faces is severe (i. e., problem severity); and whether the outcome of the exchange with the employee is successful (i. e., exchange outcome). This study contributes to deviant employee literature by illustrating how different forms of deviance shape exchange-specific responses and reciprocal customer intentions directed at the organisation and the employee.

A continuum of transformative service exchange: insights for service and social marketers

Purpose Transformative service research (TSR) and social marketing share a common goal, which is to institute social change that improves individual and societal well-being. However, the mechanism via which such improved well-being results or so-called “transformation” occurs, is not well understood. The purpose of this paper is to examine the claims made in the TSR literature to identity the themes and scholarly meaning of “transformative” service exchange; ascertain the mechanisms used in service contexts to realize transformation, including to motivate long-term, sustainable societal change; and develop a transformative service exchange continuum to guide research and managerial approaches that aim to create uplifting social change. The authors recommend their continuum as a framework to inform how social marketing and service scholars design service solutions to address wicked social problems. Design/methodology/approach This paper presents a qualitative study where Leximancer, a text-mining tool, is used to visualize the structure of themes and concepts that define transformative service exchanges as explained and applied in the literature. Additionally, a profiling analysis of transformation as it is discussed in the TSR literature is used to identify the mechanisms that service marketers have developed to establish current theorization of service thinking for social change. These qualitative phases of analysis then inform the development of the transformative service exchange continuum. Findings A scoping review identified 51 articles across 12 journals, based on this study’s selection criteria for identifying transformative service exchanges. The Leximancer analysis systematically and efficiently guided the authors’ interpretation of the large data corpus and was used in the identification of service themes. The use of text-mining software afforded a detailed lens to enrich the authors’ interpretation and clarification of six high-level concepts for inclusion on a transformative service exchange continuum. Originality/value This paper aims to unpack the meaning of transformative service exchange by highlighting the mechanism(s) used by researchers when designing social change outcomes. It contributes to TSR via the development of the continuum across micro, meso and macro levels. The temporal nature of transformative service exchanges is also elucidated. This continuum integrates current TSR studies and can guide future service studies in the TSR and social marketing domains.
