The purpose of this paper is to implement the simulation game in the cultural comparison study so as to understand the impact of cultural differences on the team interaction.

In order to focus on the factor of “national culture” and avoid other factors which can affect the results, this paper conducted a simulation game – COSIGA – for the data collection and factor control. Two sets of groups were performed to represent two national cultures – the UK and China.

This paper finds that there is more decision providing in the UK teams and more decision seeking in the China teams. The China teams used a more intuitive process to make decisions, and the UK teams used a more reference process to make decisions. There were more repetitions of the problem‐solving process in the China teams than in the UK teams. The looping problem‐solving process was present in the China teams and the linear problem‐solving process in the UK teams.

This paper presents a case study of cultural comparison using a simulation game. The selection criteria and factor control of the simulation game is outlined for the practical implications.

The purpose of this paper is to advance the understanding of product‐service systems (PSS). It uses a multiple method approach to analyse literature and cases and synthesise a framework for the understanding and investigation of PSS. It demonstrates the need to consider the “organisation” or network, of firms involved in defining, designing and delivering value through the PSS. This is conceptualised as a product‐service‐organisation (PSO).

The paper uses three complementary methodologies: a road‐mapping analysis, investigating industrial challenges for collaborating enterprises, a multidisciplinary literature review of PSS concepts and analysis of two cases.

The paper finds that value can be most effectively delivered by networks of collaborating firms, integrating the products and services they offer to create the value which customers seek. In short, creating value requires the simultaneous design of product, service and organisation – the PSO triangle.

The paper offers a new classification of PSS related literature, drawing on a broad review of research in marketing, design and operations management related to service and PSS. The framework helps researchers understand the organisational challenges of PSS and provides suggested future research directions and questions.

The framework provides the foundations for a process to develop PSS. It highlights the organisational challenges and suggests that a systematic yet iterative process can be devised to create and deliver value. This means defining customer value which can be profitably delivered; designing the PSS to create this value and identifying the required capabilities; and finally creating and managing the network of partners responsible for delivering value.

The major contribution is a link between the emerging PSS literature and previous research on virtual enterprises and other types of organisational networks. The paper argues that PSS often creates the need to identify and access capabilities through a collaborative network. This is conceptualised in the PSO triangle.

Should enterprise support for ethnic minority firms be configured along ethnic lines? This question has confronted many officers engaged in the “enterprise industry”, as they grapple with the task of supporting the increasingly significant phenomenon of ethnic minority entrepreneurship. The situation is complicated by the markedly different experiences of ethnic minority groups in business; the apparently low take‐up of existing services; and wider debates in the policy world encouraging the “integration” of business support activities. Policy initiatives to support ethnic minority businesses have had to engage with such issues; but rarely have they been documented. This paper assesses the experience in a Midlands city of AsCo, a Pakistani‐dominated business group that is attempting to “bridge the gap” between South Asians in the retail sector and the providers of business services. The paper is distinctive in a number of respects: The issue of practical enterprise support provision for South Asian firms has rarely been subject to academic scrutiny. Hence, the paper provides a rare case study of this process in action; The design of the initiative was a genuinely collaborative endeavour involving the researchers, policy makers (the local Training and Enterprise Council) and small businesses in AsCo. Indeed, the research was commissioned by the local Training and Enterprise Council (TEC) and AsCo; A methodologically heterogeneous approach is adopted. This involved in‐depth qualitative interviews with 25 member businesses of AsCo (out of a total membership of 80); ten interviews with non‐members; observations of a number of AsCo executive committee meetings; interviews with key TEC officers; and an insider’s view (the second author) of how the research has actually informed TEC policy.

The study aims to verify and establish the result of the most suitable optimization approach for higher performance and lower emission of a variable compression ratio (VCR) diesel engine. In this study, three types of test fuels are taken and tested in a variable compression ratio diesel engine (compression ignition). The fuels used are conventional diesel fuel, e-diesel (85% diesel-15% bioethanol) and nano-fuel (85% diesel-15% bioethanol-25 ppm Al₂O₃). The effect of bioethanol and nano-particles on performance, emission and cost-effectiveness is investigated at different load and compression ratios (CRs). The optimum performance and lower emission of the engine are evaluated and compared with other optimization methods.

The test engine is run by diesel, e-diesel (85% diesel-15% bioethanol) and nano-fuel (85% diesel-15% bioethanol-25 ppm Al₂O₃) in three different loadings (4 kg, 8 kg and 12 kg) and CR of 14, 16 and 18, respectively. The optimum value of energy efficiency, exergy efficiency, NO_X emission and relative cost variation are determined against the input parameters using Taguchi-Grey method and confirmed by response surface methodology (RSM) technique.

Using Taguchi-Grey method, the maximum energy and exergy efficiency, minimum % relative cost variation and NO_X emission are 24.64%, 59.52%, 0 and 184 ppm, respectively, at 4 kg load, 18 CR and fuel type of nano-fuel. Using RSM technique, maximum energy and exergy efficiency are 24.8% and 62.9%, and minimum NO_X emission and % cost variation are 208.4 ppm and –6.5, respectively, at 5.2 kg load, 18 CR and nano-fuel. The RSM is suggested as the most appropriate technique for obtaining maximum energy and exergy efficiency, and minimum % relative cost; however, for lowest possible NO_X emission, the Taguchi-Grey method is the most appropriate.

Waste rice straw is used to produce bioethanol. 4-E analysis, i.e. energy, exergy, emission and economic analysis, has been carried out, optimized and compared.
