As today’s supply chain (SC) networks are globalized complex systems planning and optimizing SC processes is harder than ever. Unexpected deviations and disruptions can lead to devastating and far-reaching consequences. Hence, the management of SC risk (SCR) is of fundamental importance. The literature on SCR is, however, mostly of anecdotic nature; only few authors present empirical research. ...

In order to understand the dynamic behavior of the variables that can play a major role in the performance improvement in a supply chain, a System Dynamics-based model is proposed. The model provides an effective framework for analyzing different variables affecting supply chain performance. Among different variables, a causal relationship among different variables has been identified. Variable...

The research work on supply-chain management has primarily focused on the study of materials flow and very little work has been done on the study of upstream flow of money. In this paper we study the flow of money in a supply chain from the viewpoint of a supply chain partner who receives money from the downstream partners and makes payments to the upstream partners. The objective is to schedul...

The revenue management concept and techniques are applied to model the coordination of supply chain elements. The fundamental premise of this approach is synchronization of a group of business entities consist-ing of a manufacturer and multiple suppliers to achieve an optimal supply chain capacity plans. The output of the supply chain can be various products and thus it is measured in terms of ...

Numerous researchers and practitioners are attracted to sustainability in supply chains (SCS) and it has become one of the favorite topics among academics and industries. The purpose of this paper is to review and analyze the research studies that have been published in the field of sustainable supply chain management (SSCM). A total 242 articles published between 2000 and 2019 reviewed. Conten...

Abstract: The implementation of government legislation, social responsibility, environmental concerns regarding the reduction of waste, hazardous material and other consumer residuals have made the competition between the firms stricter than ever and nowadays firms that want to survive need a more productive and innovative approach toward the financial aspects of their businesses.his pape...

This paper provides a risk modeling approach for Supply Chain Networks (SCNs) operating under uncertainty. It recognizes three event types to characterize the future SCN environment: random, hazardous and deeply uncertain events. A three-phase hazard modeling approach is proposed. It involves a characterization of SCN hazards in terms of multihazards, vulnerability sources and exposure levels, ...

The purpose of this research is to understand the Wine industry Supply Chain (WSC) structure from a social networks approach. This analysis will identify the appropriate measure of performance of the WSC. To achieve that objective, this paper will at first tackle the supply chain modeling on the one hand through a generic approach, and on the other hand we will propose a WSC representation from...

Uncertainty in Supply Chain Management can lead to unsuitable services to customers, but it can be overcome through having an emergency inventory. Due to high costs of inventory, a general inclination exists towards a minimum inventory. So, one of the objectives of Supply Chain Management is to coordinate all activities throughout the chain, so that simultaneously with reducing commodity invent...

This paper proposes a novel simulation-modeling framework that combines discrete-event simulations with system-dynamics simulations. The former represents both operational processes inside of a supply-chain, and the later represents management environment outside of a supply-chain. Further, the paper also discusses modeling capabilities of the proposed framework for supply-chain systems in real...
