Carbon footprinting of products and services is getting increasing attention due to the growing emphasis on carbon related policies in many countries. As a result, many enterprises are focusing on the design of green supply chains (GSCs) with research on supply chains (SCs) focused not only on cost efficiency, but also on its environmental consequences. The review presented in this paper focuses on the implications of carbon policies on SCs. The concept of content analysis is used to retrieve and analyze the information regarding drivers (carbon policies), actors (for example, manufacturers and retailers), methodologies (mathematical modeling techniques), decision-making contexts (such as, facility location and order quantity), and emission reduction opportunities. The review shows a lack of emissions analysis of SCs that face carbon policies in different countries. The research also focuses on the design of carbon policies for emissions reduction in different operating situations. Some possible research directions are also discussed at the end of this review.

The problem of product service forecasting in hierarchical service structure is common in many contexts. It is common that the results of the higher level forecasting are in conflict with the sum of the lower level forecasts. The phenomenon has confused the managers in decision making. This aim of this research is to forecast the product services demands in a hierarchical service structure context. By integrating the methods combination forecasting approach and the information combination forecasting approach, the paper provide a multi-level combined forecasting model with six steps. A case of air compressor services forecasting is employed to verify the developed approach. The in-sample and out-of-sample test indicates that the proposed model outperforms the individual models and the direct combination of individual methods. The proposed method could be easily customized for solving other product service forecasting problems, especially when the hierarchical time series data are involved.

The emergence of concerns over environmental protection, resource conservation as well as the development of logistics operations and manufacturing technology has led several countries to implement formal collection and recycling systems of solid waste. Such recycling system has the benefits of reducing environmental pollution, boosting the economy by creating new jobs, and generating income from trading the recyclable materials. This leads to the formation of a global reverse supply chain (GRSC) of solid waste. In this paper, we investigate the design of such a GRSC with a special emphasis on three aspects; (1) uncertainty of waste collection levels, (2) associated carbon emissions, and (3) challenges posed by the supply chain’s global aspect, particularly the maritime transportation costs and currency exchange rates. To the best of our knowledge, this paper is the first attempt to integrate the three above-mentioned important aspects in the design of a GRSC. We have used mixed integer-linear programming method along with robust optimization to develop the model which is validated using a sample case study of e-waste management. Our results show that using a robust model by taking the complex interactions characterizing global reverse supply chain networks into account, we can create a better GRSC. The effect of uncertainties and carbon constraints on decisions to reduce costs and emissions are also shown.

The service industry has become an engine of regional and global economic development, and the employment and revenue of the service industry are increasing dramatically in recent years. This chapter discusses product-service supply chain (PSSC) design by outlining the PSSC implications and focusing on the crucial elements of PSSC design. Viewing the subject from the perspective of manufacturers, several presentations are used in practice, such as the supply chain for after-sales service; maintenance, repair, and operations; and product-service systems providing. It first explains what is the PSSC and then moves on to the prominent features and the structure of the PSSC. In a general sense, PSSC design is designed toward the value of all supply chain members by configuring the service resource reasonably. From the viewpoint of supply chain design , five elements are elaborated in this chapter, which include the PSSC strategy, service facility location, outsourced service supplier selection, service network configuration, and process design for PSSC. The approaches for the PSSC design are reviewed, suggested, and elaborated.
