This article presents an integrated approach for designing a reverse logistics network by minimizing the carbon emissions and the transportation distances between different candidate centers while considering several system design and operational issues of a Hybrid Manufacturing-Remanufacturing System operating within the abovementioned reverse logistics network. Accordingly, the article attempts to integrate various sustainability aspects indoctrinated in the Sustainable Manufacturing philosophy. In view of this, a mixed integer programming model for designing a reverse logistics network is developed. The model considers the carbon foot print, facility location, and the material flow aspects of the reverse logistics network; in which a hybrid manufacturingremanufacturing system is integrated. A detailed discussion of a numerical example is presented to illustrate the proposed model. The model has potential applications for supply chain managers designing a reverse logistics networks as well as for production managers at the operations level.

When a product ceases to be of any further use to the customer in it is current condition, it is relinquished. Accordingly, there is a need for a product recovery options in a sustainable environment. Recycling and remanufacturing are the most two advanced product recovery options. An efficient recycling and remanufacturing network leads to an efficient design of Sustainable Manufacturing enterprise. This article presents a simultaneous investigation of Reconfigurable Cellular Manufacturing Systems and Hybrid Manufacturing-Remanufacturing Systems (HMRSs), and proposes an integrated approach in design optimization, analysis, and process planning aspects as an attempt to address to a large number of design issues for Sustainable Manufacturing Systems. The options of remanufacturing, recycling, and disposing are introduced. A mixed integer linear programming (MILP) model, which considers a classical cell formation problem in Cellular Manufacturing Systems (CMSs), bridged with a production planning problem, in Hybrid Manufacturing-Remanufacturing Systems, while addressing to "reconfiguration" issues for the CMS for different production periods, has been developed. A numerical example is presented to illustrate the proposed model.

While sustainability appears to be a popular research area in general, one cannot observe much emphasis on research in design issues of sustainable manufacturing systems presently. In wake of this, this article presents a simultaneous investigation of reconfigurable cellular manufacturing systems (CMSs) and hybrid manufacturing-remanufacturing systems and proposes an integrated approach in design optimization, analysis, and process planning aspects as an attempt to address to a number of design issues for “sustainable manufacturing systems.” A mixed integer linear programming (MILP) model, which considers a classical cell formation problem in CMSs, bridged with a production planning problem, in hybrid manufacturing-remanufacturing systems, while addressing to “reconfiguration” issues for the CMS for different production periods, has been developed. Numerical examples are provided. A detailed discussion of a numerical example is presented to illustrate the proposed model.

The proposed DCMS model considers several manufacturing attributes such as multi period production planning, dynamic system reconfiguration, duplicate machines, machine capacity, the available time for workers, worker assignments, and machine procurement. The objective is to minimize total costs; consisting of holding cost, outsourcing cost, inter-cell material handling cost, maintenance and overhead cost, machine relocation cost. While a study of published articles in the area of Cellular Manufacturing Systems (CMS) shows that workforce management issues have not sufficiently been addressed in the literature, the model presented also incorporates CMS workforce management issues such as salaries, hiring and firing costs of workers in addition to the manufacturing attributes. In-depth discussions on the results for two numerical examples are presented to illustrate applications of the proposed model. The model developed aims to raise the envelope by expanding and improving several CMS models previously presented in the literature.

Traditional manufacturing systems, such as job shops and flow lines, cannot provide such requirements efficiently coupled with flexibility to handle these changes. Cellular Manufacturing (CM) is an alternate manufacturing system combining the high throughput rates of line layouts with the flexibility offered by functional layouts (job shops). The benefits include reduced set-up times, material handling, in-process inventory, better product quality, and faster response time. The benefits of CM can only be achieved by sufficiently incorporating the real-life structural and operational features of a manufacturing plant when creating the cellular layout. This research presents integrated CM models, with an extensive coverage of important manufacturing structural a...

Even though, there is a relatively growing interest from both academic researchers and practitioners in various design aspects of sustainability, one can see that design issues of sustainable manufacturing systems have not received adequate attention. Through an extensive literature review on design for sustainability and sustainability issues, it is observed that, attaining sustainability in manufacturing needs a huge amount of effort and needs to take into consideration many aspects from different perspectives. These include considering the sustainability in both the closed loop supply chain (CLSC) and the manufacturing system levels simultaneously, considering Cellular Manufacturing Systems (CMSs), considering reconfigurability for the production systems, considering Hybrid Manufacturing-Remanufacturing Systems as well as considering the recovery options such as recycling and remanufacturing.

In remanufacturing network, products are collected from the customer zone, disassembled and remanufactured at a suitable remanufacturing facility. In this respect, another issue to consider is how the returned product to be remanufactured, in other words, what is the best layout for such facility. In order to achieve a sustainable manufacturing system, Cellular Manufacturing System (CMS) designs are highly recommended, CMSs combine high throughput rates of line layouts with the flexibility offered by functional layouts (job shop). Introducing the CMS while designing a remanufacturing network will benefit the utilization of such a network. This paper presents and analyzes a comprehensive mathematical model for the design of Dynamic Cellular Remanufacturing Systems (DCRSs). In this paper, the proposed model is the first one to date that considers CMS and remanufacturing s...
