“…Modelling and evaluation can be used to improve waiting time based on system bottlenecks and using techniques such as workflows and new arrangements [ 28 ]. Modelling represents an executable illustration of system characteristics and their behaviour at the time of execution [ 12 ]. Various models exist to serve an executable system [ 6 ].…”

The COVID-19 epidemic has spread across the world within months and creates multiple challenges for healthcare providers. Patients with cardiovascular disease represent a vulnerable population when suffering from COVID-19. Most hospitals have been facing difficulties in the treatment of COVID-19 patients, and there is a need to minimise patient flow time so that staff health is less endangered, and more patients can be treated. This article shows how to use simulation techniques to prepare hospitals for a virus outbreak. The initial simulation of the current processes of the heart clinic first identified the bottlenecks. It confirmed that the current workflow is not optimal for COVID-19 patients; therefore, to reduce waiting time, three optimisation scenarios are proposed. In the best situation, the discrete-event simulation of the second scenario led to a 62.3% reduction in patient waiting time. This is one of the few studies that show how hospitals can use workflow modelling using timed coloured Petri nets to manage healthcare systems in practice. This technique would be valuable in these challenging times as the health of staff, and other patients are at risk from the nosocomial transmission.

“…The IFSVC pre-supposes that the SVC (and sanitation economy) cannot be effective unless all stages are working connectively in an integrated synergistic systemic manner (Koottatep et al, 2019) across local, regional and international arenas focusing on vertical and horizontal relationships between actors (Trienekens, 2011). Traditional value chains are linear processes, where upstream suppliers provide material for products or services, and downstream units provide distribution and point of sale (Chofreh et al, 2019;Reese et al, 2016). However, the IFSVC is a non-linear system that links all enterprises, businesses and actors across the sanitation spectrum from local, regional, national and international systems involved in adding value to each stage of Re-conceptualizing the sanitation value chain the sanitation value chain until the products and/or services reach the hands of the end-users.…”

Thus, the value chain has become a critical tool that, not only identifies the potential stage to increase customer value and to reduce costs, but also understands business relationships with stakeholders [33].…”

Agrifood value chain assessment in developing countries: a case of Indonesia’s cashew sector

2021

View full text Add to dashboard Cite

A value chain approach is increasingly used in the agrifood sector to help respond to the globalised food system. However, the agrifood value chain in many developing countries faces additional challenges to address any changes regarding the prevalence of smallholder players. Meanwhile, value chain studies are still limited in many developing countries, such as in Indonesia. Therefore, this paper aims to assess agrifood value chain in a developing country context. A qualitative methodology was applied in Indonesia’s cashew sector, specifically in the Sumenep Regency of Madura Island. A value chain mapping tool was used by focusing on governance (vertical-horizontal coordination and information flow) and value addition (safety, quality, and value orientation). The results showed that value chain mapping is a powerful tool to draw the complex interaction within the dynamics between different value chain actors. The exploration in Indonesia’s cashew sector showed that there is a gap in practices between actors in terms of governance and value addition. Therefore, it is recommended that smallholders’ governance participation and value adding activities be improved in order to minimize the gap of practises. The potential follow-up research is to address the maturity level of value chain practice to obtain a rigorous improvement route.
