Over the last few decades, microfinance industry is argued to have played a constructive role in alleviating poverty level and providing the underprivileged with access to financial services. Statistics from the World Bank reveal that, currently, only 4% of the underprivileged have been served out of the 3 billion+ potential clients. Such results are due to several claims, particularly the operational and financial challenges faced by microfinance institutions (MFIs) in the constant flux inviting more attentions towards its performance. While explicit attention is given by many researchers towards mobile banking and information and communication technology (ICT) in improving the MFIs’ performance, the study on how social media, as a rapidly growing online phenomenon, can impact on the MFIs’ performance remains scarce. As such, this study aims to investigate this impact based on four dimensional performance indicators: efficiency, financial sustainability, portfolio quality and outreach.

A model is proposed and tested to ascertain the relationship between social media applications and organisational performance. In so doing, web-based questionnaires have been used to collect data from MFI employees in developing countries. Results reveal a significant influence of the social media over the MFIs’ performance, offering valuable insights into both researchers and practitioners in the domain of microfinance, as well as social media—conforming that the adoption of social media as marketing, advertising and communication tools may significantly improve the MFIs’ performance.

The results demonstrate that there is a positive and significant impact of social media use within microfinance on the key indicators of MFIs. They also show that the highest impact of social media usage within the microfinance is on the portfolio quality. In addition, it was found that marketing and advertising; communication and sales and distribution are the main areas where social media is able to support while social networking websites are the most popular platforms employed in MFIs.

This study adds to the existing literature few theoretical and practical aspects. First, this study developed a model for assessing the value of social media as a new phenomenon within this type of organisation. Second, it offers microfinance sponsors, managers and policy makers with a frame of reference to understand what social media platform can be deployed for each purpose. Third, with the identification of the main MFIs’ performance indicators, this research provided a reference of performance measurement guide for microfinance industry when assessing different technological employment.

The purpose of this paper is to consider a number of issues around the poor adoption of healthcare simulation models and reflect whether there has been a broad failure of academic healthcare simulation modellers to build models that reflect real healthcare problems as acknowledged by healthcare stakeholders. This paper will also review the role of healthcare planners within the health sector and propose that they are well suited to act as change agents to improve the adoption of simulation within the sector.

This paper reviewed academic evidence around poor adoption of simulation modelling in healthcare, including differences to other sectors, its size and complexity, stakeholder issues and current and future challenges to improve operational efficiency. This paper also reviewed the role of healthcare planning and its valuable links with health stakeholders, suggesting that these links could be exploited to increase simulation modelling within the healthcare sector to improve operational efficiency.

This paper highlights the strong links between healthcare planning and the healthcare stakeholders and proposes that healthcare planning can play a key role in adoption of healthcare simulation modelling to achieve operational efficiency improvements.

This paper illustrates the potential link between healthcare planning and healthcare stakeholders to achieve operational improvements within the health sector.

With the ever-expanding online shopping, electronic word-of-mouth (eWOM) has become a significant factor affecting the consumer decision-making behaviour. This is specially the case when considering Generation Y (Millennials), who are old enough to be independent buyers and young to be almost immersed in online living. This article aims to assess the impact of eWOM on purchase intention by developing a conceptual model of hypotheses encompassing a multitude of factors that may be associated with this relationship.

The researcher investigates what factors impact eWOM credibility and make the consumer may adopt it when making a purchase. To examine our research model, a quantitative approach is employed for this purpose using a sample through online survey from Thailand – where there is a large number portion Generation Y consumer base.

It was found that source style as a visual attribute information is the most significant factor that may impact eWOM credibility in addition to source credibility, argument quality and source homophily, respectively.

From a practical point of view, it helps firms to understand what needs to be taken into consideration when building their marketing strategy.

This is believed to add significant insights into the eWOM literature by identifying its route of impact toward the purchase intention on Generation Y.

This paper looks at a number of approaches to health informatics that support decision‐making relevant to the integrated development and management of information systems with clinical and managerial practices in healthcare. Its main aim is to explore three such approaches for integrated development, the soft information systems and technologies methodology, participative simulation modelling and stakeholder analysis. A description of the health informatics research and development environment in the UK is given as necessary background to the paper. Organisational and social aspects are examined through these approaches including information and clinical process development, telemedicine, ethical issues of drug use and management, health policies and information management and strategies, tele‐education and modelling structures. In the conclusion the synergies between the three approaches are discussed and some principles are extracted for future research and development in integrated approaches to health informatics research.

The purpose of this paper is to identify the existing literature on the wide range of operations research (OR) studies applied to healthcare, and to classify studies based on application type and on the OR technique employed. The scope of the review is limited to studies which have been undertaken in the UK, and to papers published since the year 2000.

In total, 142 high‐quality journal and conference papers have been identified from ISI Web of Knowledge data base for review and analysis.

The findings categorise the OR techniques employed, and analyse the application type, publication trends, funding, and software packages used in the twenty‐first century in UK healthcare. Publication trends indicate an increasing use of OR techniques in UK healthcare. The findings show that, interestingly, the distribution of the OR techniques employed is not uniform; the majority of studies focus on simulation, either as the only technique employed or as one element of a multi‐method approach.

Several studies have focused on the use of simulation in healthcare modelling, but none has methodologically reviewed the use of the full range of OR techniques. This research is likely to benefit healthcare decision makers since it will provide them with an overview of the different studies that have utilised multiple OR techniques for investigating problems in the stated domain.

The purpose of this paper is to carry out the business process re‐engineering (BPR) of a surgical ward in a hospital in order to improve the efficiency of the ward.

This work was developed using a case study on a surgical ward. In this type of ward, in which scheduled and unscheduled operations often have to coexist and be managed, ways to minimise patient inconvenience need to be studied. A framework based on event‐driven process chains (EPCs) methodology, the entity‐relationship model and discrete event simulation is presented to define and analyse the current state of a surgical ward and design a future system. The modelling of the processes, activities and sub‐activities, which took up a great amount of ward resources, allowed a what‐if analysis to be developed which simulates various scenarios and assesses their performance.

Using Delphi methodology, it was possible to identify a number of areas for improvement: number of operating sessions, preparation of the operating rooms for each operation, availability of specific surgical instruments. Moreover, the discrete event simulation approach led to an understanding of the most efficient management choices.

The decision to use Delphi methodology for the information collection stage before starting the BPR process is not found in other studies in the literature. Moreover, the use of models based on EPCs methodology allowed the panel of experts to develop models to examine and understand the resource requirements of medical assessment units and to provide a framework or develop standards that hospital developers and clinical managers can consult.

The purpose of this paper is to develop a generic framework for hybrid (integrated deployment of system dynamics and discrete event simulation) simulation which can be applied in the healthcare domain.

As hybrid simulation in an organisational context is a new topic with limited available data on deployment of hybrid simulation in organisational context, an inductive approach has been applied. On the basis of knowledge induced from literature, a generic conceptual framework for hybrid simulation has been developed. The proposed framework is demonstrated using an explanatory case study comprising an accident and emergency (A&E) department.

The framework provided detailed guidance for the development of a hybrid model of an A&E case study. Findings of this case study suggest that the hybrid model was more efficient in capturing behavioural impact on operational performances.

The framework is limited to only SD and DES; as agent‐based is another simulation method which is emerging as a promising tool for analysing problems such as spread of infectious diseases in healthcare context, inclusion of this into the framework will enhance the utility of the framework.

This framework will aid in the development of hybrid models capable of comprehending both detail as well as dynamic complexity, which will contribute towards a deeper understanding of the problems, resulting in more effective decision making.

It is expected that this research will encourage those engaged in simulation (e.g. researchers, practitioners, decision makers) to realise the potential of cross‐fertilisation of the two simulation paradigms.

Currently, there is no conceptual framework which provides guidance for developing hybrid models. In order to address this gap, this paper contributes by proposing a conceptual framework for hybrid simulation for the healthcare domain.

The purpose of this paper is to present a business process reengineering (BPR) framework of process and data integration with patient journey as the basis for process evaluation and the improvement of patient-flow.

A BPR framework is developed using a mixed-method research design, which incorporated a case study to demonstrate a healthcare scenario with associated processes and data elements, using process models based on event-driven process chain methodology as well as patient and data models, based on unitary structuring technique. The framework includes key processes including patient booking and rebooking, and associated inputs, outputs, and control parameters. In this case, the framework is demonstrated through application to computed tomography (CT) services in a hospital to improve patient-flow, with numerical simulation of CT data collected over time.

The framework supports flexible patient scheduling and the associated planning of healthcare operations and logistics – this in turn helps to improve patient-flow. Furthermore, mathematical modelling and simulation precisely reveal the impact of booking and rebooking on the performance of the CT department.

This innovative framework has potential value for other services, within and beyond the hospital setting.

The proposed framework of process modelling, data, and patient journey addresses the lack of a holistic approach to monitoring and evaluating service performance in hospital settings. Patient journey modelling is an integral part of process and data models that can be implemented in an integrated system environment such as an enterprise resource planning system for real-time monitoring of patient-flow under dynamic conditions.

The design of manufacturing systems is a complex and expensive task for both SMEs and large organisations alike. Many problems relating to the design and operation of manufacturing systems are too complex to allow for mathematical treatment, and as a result there is increasing recognition of the applicability of simulation in the manufacturing environment. This has in turn resulted in a growth in simulation software products available in the marketplace, and manufacturers of such products are naturally keen to extol the virtues of what they sell. In a rapidly changing workplace, there is some suggestion that simulation tools may not have developed to deal with the new demands, and so it is timely to review what is on offer. This paper presents the results of a survey of European simulation specialists, both working in industry and in an academic environment, on the use of simulation software. The main purpose of this survey was to determine how satisfied users are with simulation software and to highlight the most positive and negative features. The findings offer an insight into current software, and how this can be further enhanced.

Discrete event simulation (DES) application is not as widely perceived as being useful for problem solving in the health‐care arena as in other application areas. Suggests that this might be due to the way DES is applied in health‐care modelling, as it follows a traditionally based‐on‐engineering approach. This may not be a problem in itself; however, health‐care systems are often complex in that they involve multiple decision‐makers and thus understanding and communication between the various stakeholders are potentially problematic. Thinks that problem understanding and efficient communication tools largely contribute to the solution; consequently, proposes a modelling approach to enhance stakeholder understanding and communication. The approach is based on participation of stakeholders; it is also iterative rather than step‐based. To demonstrate this approach, gives an example, aiming to show how this approach has been used successfully to facilitate the understanding process, concluding that involving stakeholders throughout not only helps them to understand their problem better, but also enables them to more fully appreciate the findings resulting from the model. This approach thus serves usefully to enrich the communication between the stakeholders.
