The paper proposes both statistical and simulation-based analysis and evaluation of the bullwhip effect in supply chains. The demand distortion, called the bullwhip effect, is considered as an important characteristic of supply chain operation stability. A mathematical justification of the stochastic demand as a cause of the bullwhip effect is discussed. Results of simulation studies to analyse...

We study a supply chain economy that comprises heterogeneous supply chains involving multiple products and competing for multiple markets. The proposed network model is built upon operation links and interface links, representing, respectively, substantial supply chain operations and coordination functions between the operations. The paper presents a variational inequality formulation of the pr...

Following the increasing intensity of competition in the market, more and more enterprises choose supply chain as its model of business operation. In this paper, a multi-agent based model of supply chain system in manufacturing is constructed on the basis of supply chain system with complex adaptive system. The same agent model is constructed respectively from the enterprise entity perspective ...

the aim of this study was to represent effective componentsin demand chain which help organizations attain high performance levelsthrough identification of these components and determining theirdegree of importance. the following questions were major ideas of thisstudy: what are the most effective components in demand chain? andhow are they effective on organizational performance? to this end,m...

In the contemporary global market, managing the entire supply chain has become crucial for competitive advantage in different industries. However, the realization and success of supply chain management (SCM) depends significantly on the previous supply chain modeling and simulation for analyzing complex systems. This study develops a modular approach for system analysis and design of supply cha...

Supply chain managers are trying to maximize the profitable operation of their manufacturing and distribution supply chain, but due to global competition in process industries and complexities of the supply chain processes together with large computational times, it has made optimization of supply chain management (SCM) quite difficult. Recently, Knowledge management (KM) is a new important inf...

We are experiencing a digital revolution that is rapidly changing the way business is conducted. In this new economy, information is shared speedily and many participants are collaborating. Effective and seamless collaboration between distributed supply chain members is therefore crucial. To understand how this may be done, we describe a knowledge based framework for abstracting, enriching, ana...

Supplying chain cooperation has already become an important strategy that enterprises use to tackle market competition; however, the supply chain crisis caused by supply chain risk makes the supply chain operation of enterprises very fragile. This paper applies Portfolio Theory to explain the suppliers’ combination plays an important role in dispersing the supplying chain risk and controlling i...

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 ...

in recent years, there has been a great concern about strategic supply chain management. the supply chain configuration approach is related to strategic management of material and information flows. most of suggested configurations in the part of strategic direction are based on environmental factors and structure-conduct-performance approach. exploring supply chain configuration with emphasis ...
