Item Open Access Conceptualising the impact of information asymmetry on through-life cost: case study of machine tools sector(Elsevier, 2019-11-02) Farsi, Maryam; Grenyer, Alex; Sachidananda, Madhu; Sceral, Mario; Mcvey, Steve; Erkoyuncu, John Ahmet; Roy, RajkumarInformation asymmetry (IA) in terms of contextual variety and importance is one of the most challenging aspects of through-life costing in product-service systems (PSS). IA is an imbalance in the information, data and knowledge shared among the parties involved in a contractual agreement. In manufacturing systems under PSS, interaction and effective communication among several parties who are involved in a contractual agreement, rely on the continuity and accuracy of information and context. In such systems, contextual variety exhibits complexity and uncertainty in through-life costing and subsequently in PSS cost assessment. Although the economic aspect of PSS has been studied previously, the impact of IA on through-life cost and for different PSS solutions has not been detailed. Considering manufacturing value chains, this paper introduces a new concept of PSS-hierarchy to perform through-life costing in the presence of IA for various PSS solutions. Moreover, this paper proposes a generic life-cycle model for different PSS solutions to assess the total cost of ownership (TCO). The proposed model has been developed to support decisions on contract design in manufacturing systems. This study considers the manufacturer, service provider and customer perspectives to develop the TCO model using a machine tool manufacturing case study.Item Open Access Identifying information asymmetry challenges in the defence sector(Elsevier, 2018-02-08) Sceral, Mario; Erkoyuncu, John Ahmet; Shehab, EssamNowadays austerity policy and reduced funding promote the Defence Sector (DS) interested in improving interactions across the supply network to achieve more outcomes with less expense. The quality of the information link plays a key role in the supply chain. The information is often lost causing costs increase. Information Asymmetry (IA) exists when two or more parties in a contract/project have different types or amounts of information, and choose not to share or fail to understand information that is shared. This paper aims to outline some of the challenges faced within the DS as a result of the existence of IA. This is the first step towards improving the management of IA and has been supported by a literature review and through semi-structured interviews with subject matter experts. Therefore, the conclusions in this paper can be used for further developments in this area of study.
