This study investigated how greenhouse managers should invest in preservation and green technologies and introduce trade credit to increase their profits. We propose a supply chain inventory model with controllable deterioration and emission rates under payment schemes for shortage and surplus, where demand depends on price and trade credit. Carbon emissions and deterioration are factors affecting global warming, and many greenhouse managers have focused on reducing carbon emissions. Carbon caps and tax-based incentives have been used in many greenhouses to achieve such reduction. Because of the importance of reducing carbon emissions for developing a green supply chain, various studies have investigated how firms deal with carbon emission constraints. In this continuation, we have used green technology to curb the excessive emissions from the environment or make it clean from CO2. In a seller–buyer relationship, the seller can offer a trade credit period to the buyer to manage stock and stimulate demand. Deterioration may become a challenge for most firms as they are under time constraints control, and preservation technology could help. This study proposes three novel inventory strategies for a sustainable supply chain (full backorder, partial backorder, and no backorder), linking all these important issues. The solution optimizes total annual profit for inventory shortage or surplus. We conducted a numerical study with three examples to evaluate the model’s authenticity and effectiveness and demonstrate the solution technique. The deterioration and emission rates can be included in a trade credit policy to increase greenhouse profits. The results suggest that greenhouse managers could apply the proposed model to manage real-world situations.

Total Profit

Carbon cap-and-trade and carbon offsets are common and important carbon emission reduction policies in many countries. In addition, carbon emissions from business activities can be effectively reduced through specific capital investments in green technologies. Nevertheless, such capital investments are costly and not all enterprises can afford these investments. Therefore, if all members of a supply chain agree to share the investments in the facilities, the supply chain can reduce carbon emissions and generate more profit. Under carbon cap-and-trade and carbon tax policies, this study proposes a production–inventory model in which the buyer and vendor in the integrated supply chain agree to co-invest funds to reduce carbon emissions. We planned to integrate production, delivery, replenishment, and technology to reduce carbon emissions so as to maximize the total profit of the supply chain system. Several examples are simulated and the sensitivity analysis of the main parameters is carried out. The optimal solutions and joint total profit under various carbon emission policies are also compared. The future carbon emission control trend is expected to enable companies to share risks by co-investing and developing sustainable supply chains.

Conventional EOQ models always discussed profit maximization for one player at a time. But modern approach of supply chain suggests that growing and sustainable supply chain is possible only when benefits of all members of chain are protected. This chapter proposes an integrated model of supply chain where units in inventory are subjected to time dependent deterioration. Since demand is inversely proportional to selling price of the item, it is assumed selling price dependent. To make it more practical and feasible permissible delay on payments is offered only on purchase of a certain amount of quantity. This chapter helps to offer an algorithm to attain optimal number of orders, quantity, selling price and trade credit to maximize the joint profit of supply chain. Isolated profit of supply chain is compared with overall system profit. Results are validated by numerical examples and further sensitivity analyses of important parameters are discussed. Conclusion obtained from the chapter is useful to supply chains involved with FMCGs, Drugs, Fashion goods and home decor textile.

Fresh Food

The production, processing, transportation, and consumption of fresh food have a significant impact on the sustainable development of the whole fresh food supply chain. There are relatively few methods and techniques to qualitatively analyze the dynamic driving factors of fresh food sustainable supply-chain management (SSCM). To solve this problem, this paper first sorts out the drivers dimensions and specific impact indicators of fresh food SSCM through the literature. Then, the integration of rough set theory and decision laboratory analysis reveals the internal strength, external connection, and comprehensive influence degree, while the prominence and relation of the driving factors are tested which reflects their priority. The results show that the competitiveness of the supply chain, food security, and strategic are the main driving factors of SSCM. Attention should be paid to green technology, product design, and green logistics. The creation and distribution of added value, as well as food security management, should be improved.

The Government

Malaysia has committed to a 40% reduction of carbon emissions by 2020. The government has encouraged industry, society, and non-government organizations to work together to achieve this objective. The government has provided incentives through several energy programmes such as energy efficiency, renewable energy, green technology, and green building. One key area that has been targeted is logistics and supply chain, which has been contributing to high carbon emissions in manufacturing industries. Scholars and practitioners have only recently begun to pay attention to creating a low carbon supply chain. Furthermore, Small Medium Enterprises (SMEs) have faced several challenges in adopting low carbon activities. SMEs are unable to take the advantage of energy initiatives because of a lack of knowledge, a shortage of funds, and inadequate facilities. Almost 90% of firms are in the service industry working with large manufacturing firms and some SMEs working in manufacturing industry are working closely with their supply chain networks; achieving low carbon targets is hampered by the readiness of the manufacturing itself. This chapter discusses the challenges and future agenda of creating low carbon supply chains in manufacturing in Malaysia. Possible solutions are provided at the end of the chapter.
