“…The VSC can be distinguished from a traditional SC because of its flexibility to quickly accept and adapt to changes in the business environment. The VSC is the cooperation in an SC, via the Internet, by a dynamic network of associate organizations whose ordinary operations are basically Internet-based (Scott and Mula, 2009). SC partners work together in their business operations to gain or maintain a competitive advantage in the global marketplace (Ahmed et al, 2021).…”

“…SC partners work together in their business operations to gain or maintain a competitive advantage in the global marketplace (Ahmed et al, 2021). The goal of these partner organizations is to take advantage of business opportunities to deliver unique goods promptly (Scott and Mula, 2009).

“…Sharing information in a VSC can enrich general information to recover the results of operations. The integration of information systems and internet-based technology can assist to develop a VSC (Scott and Mula, 2009). The concept of the VSC has been introduced in the light of e-commerce systems to meet the need for SC transparency (Helo et al, 2014).…”

PurposeSupply chains (SCs) have been growingly virtualized in response to the market challenges and opportunities that are presented by new and cost-effective internet-based technologies today. This paper designed a virtual closed-loop supply chain (VCLSC) network based on multiperiod, multiproduct and by using the Internet of Things (IoT). The purpose of the paper is the optimization of the VCLSC network.Design/methodology/approachThe proposed model considers the maximization of profit. For this purpose, costs related to virtualization such as security, energy consumption, recall and IoT facilities along with the usual costs of the SC are considered in the model. Due to real-world demand fluctuations, in this model, demand is considered fuzzy. Finally, the problem is solved using the Grey Wolf algorithm and Firefly algorithm. A numerical example and sensitivity analysis on the main parameters of the model are used to describe the importance and applicability of the developed model.FindingsThe findings showed that the Firefly algorithm performed better and identified more profit for the SC in each period. Also, the results of the sensitivity analysis using the IoT in a VCLSC showed that the profit of the virtual supply chain (VSC) is higher compared to not using IoT due to tracking defective parts and identifying reversible products. In proposed model, chain members can help improve chain operations by tracking raw materials and products, delivering products faster and with higher quality to customers, bringing a new level of SC efficiency to industries. As a result, VSCs can be controlled, programmed and optimized remotely over the Internet based on virtual objects rather than direct observation.Originality/valueThere are limited researches on designing and optimizing the VCLSC network. This study is one of the first studies that optimize the VSC networks considering minimization of virtual costs and maximization of profits. In most researches, the theory of VSC and its advantages have been described, while in this research, mathematical optimization and modeling of the VSC have been done, and it has been tried to apply SC virtualization using the IoT. Considering virtual costs in VSC optimization is another originality of this research. Also, considering the uncertainty in the SC brings the issue closer to the real world. In this study, virtualization costs including security, recall and energy consumption in SC optimization are considered.HighlightsInvestigates the role of IoT for virtual supply chain profit optimization and mathematical optimization of virtual closed-loop supply chain (VCLSC) based on multiperiod, multiproduct with emphasis on using the IoT under uncertainty.Considering the most important costs of virtualization of supply chain include: cost of IoT information security, cost of IoT energy consumption, cost of recall the production department, cost of IoT facilities.Selection of the optimal suppliers in each period and determination of the price of each returned product in virtual supply chain.Solving and validating the proposed model with two meta-heuristic algorithms (the Grey Wolf algorithm and Firefly algorithm).

“…Organizations engaged in interorganizational relationships can use IOISs to collaborate for achieving mutual goals. IOISs, as well as other information systems, can collect, store, transform, and share data, being shared by two or more organizations and supporting the interorganizational relationship lifecycle phases [Barrett andKonsynski 1982, Scott andMula 2009]. However, the characteristics of interorganizational relationships or the lack of deeper knowledge about them affect the adopted systems, thus causing the non-specification of a complete IOIS and the difficulty of identifying and managing people involved in IOIS development [Boonstra e de Vries 2008].…”

“…An important tool in these relationships is the Interorganizational Information Systems (IOIS). These systems are, by definition, shared by two or more organizations, thus supporting the performed activities, information processing, and communication between stakeholders, which implies a level of cooperation that goes beyond the relationships and interactions commonly observed between organizations [ Barrett andKonsynski 1982, Scott andMula 2009]. However, although some academic works aim to understand interorganizational relationships and IOISs better [Diirr e Cappelli 2018, Diirr e Santos 2019, there is still an investigation gap regarding real cases.…”

Interorganizational relationships are initiatives between organizations that aim to facilitate resource sharing and information exchange. In this context, information systems are developed to support the involved organizations, often encompassing several smaller systems. However, little is known about interorganizational information systems (IOIS), especially regarding their state of practice. This paper investigates the use of IOISs in real scenarios. For this, we performed a non-systematic search of IOISs examples and identified repositories on GitHub about these systems. Hence, it was possible to map a set of sources and requirements that help understand how IOISs work and why they are adopted.
