  • closed loop supply Chain network with interaction of Forward and reverse logistics
    Sustainable Production and Consumption, 2021
    Co-Authors: Qiang Qiang, Zuqing Huang
    Abstract:

    Abstract Beneficial to the environment but complex in nature, closed-loop supply Chain (CLSC) has been understandably a topic of studies for a lot of researchers. However, most of the literature focuses on the homogeneity of CLSC products and on the dyadic structure of the CLSC mostly involving single manufacturers, distributors, or retailers. Very seldom do we find studies conducted in the analysis of the CLSC with network structure, in which multiple agents compete and coordinate. Inspired by some recent business cases, we develop a coupled CLSC network model dealing with heterogeneous products facing different market demands. The end-of-life product from the Forward supply Chain is collected and recycled so that raw material can be extracted and used as an input for the reverse supply Chain which produces another type of product. Moreover, in each supply Chain, raw material suppliers, manufactures, and retailers have to compete and coordinate to satisfy the demand while the Forward and reverse supply Chains have to work together to materialize the supply Chain “loop”. Additionally, a CLSC network equilibrium is defined and studied by using variational inequalities. The properties of the equilibrium solution are also examined. By applying the modified projection method, we analyze a series of numerical examples. Based on the proposed model, the managerial insights are provided to show how the market size of the Forward Chain, raw material costs in both Forward Chain and reverse Chain impact the demand, equilibrium prices and total profits of the CLSC network. It is also worth noting that the consumers' environmental awareness is critical to make the coupled CLSC networks viable.

  • A multi-criteria optimization approach to manage environmental issues in closed loop supply Chain network design
    Journal of Cleaner Production, 2015
    Co-Authors: Kiran Garg, Ali Diabat, Devika Kannan, P. C. Jha
    Abstract:

    Imposition of strict environmental protection acts and the imperative need of best possible allocation of resources have given birth to the concept of “low carbon logistics.” Environmental laws force the manufacturers to extend their existing supply Chains to form a closed loop supply Chain (CLSC) through the setup of an efficient recovery system. In this paper, we attempt to deal with the environmental issues presented in the design of CLSC networks. The CLSC network proposed in the paper consists of four echelons in the Forward Chain and five echelons in the backward Chain. To consider the environmental issues in the proposed CLSC network, we formulate a bi-objective integer nonlinear programming problem, and in order to solve it we propose an Interactive Multi- Objective Programming Approach Algorithm. This model determines the optimal flow of parts and products in the CLSC network and the optimum number of trucks hired by facilities in the Forward Chain of the network. A numerical experimentation of the proposed model to validate the applicability of the model is done with the help of data from a real life case study. The case presented in the paper is based on a geyser manufacturer, and its application on the model provides us with the underlying tradeoffs between the two objectives. The model also results in a very interesting fact that with the implication of the extended supply Chain, a firm can create a green image of their product which eventually results in an increase in their demand while significantly reducing their usage of transportation in both directions.

  • economic social and environmental benefits through poultry Forward and reverse supply Chain
    Social Science Research Network, 2011
    Co-Authors: Mohammad Shamsuddoha, Des Klass, Mohammed Quaddus
    Abstract:

    In addition to profit, industries are becoming more responsive to social and environment issues that are striving to become stakeholder friendly. Executives must maintain supply Chain issues more efficiently to reach such credentials. Supply Chains along with sustainability are being practiced to attain such success as sustainability use triple bottom line theory. The poultry industry in Bangladesh, which is the focus of this paper, has a long Forward and reverse supply Chain. The perception is that this Chain can be taken advantage of in achieving economic, social and environmental sustainability utilizing Forward Chain and waste resources. Understanding the Forward and reverse supply Chain is seen as the key for social, economic and environmental development. The objective of this paper is to review related literature and develop a conceptual sustainable supply Chain model for the poultry industry. The model will be tested using real life data to study the impact of Forward and reverse supply Chain over society, economy and the environment.
