This paper develops a fuzzy two-layer supply chain for manufacturer and retailer with defective and non-defective types of products. The manufacturer produces up to a specific time, including faulty and non-defective items, and after the screening, the non-defective item sends to the retailer. The retailer’s strategy is to do the screening of items received from the manufacturer; subsequently, the perfect quality items are used to fulfill the customer’s demand, and the defective items are reworked. The retailer considers that customer demand is time and reliability dependent. The supply chain considers probabilistic deterioration for the manufacturer and retailers along with the strategies such as production rate, unit production cost, cost of idle time of manufacturer, screening, rework, etc. The optimum average profit of the integrated model is evaluated for both the cases crisp and fuzzy environments. Managerial insights and the effect of changes in the parameters’ values on the optimal inventory policy under fuzziness are presented.

Abstract Supply Chain makes the flow of goods, services and information from suppliers, through transport, producers, distributors, retailers to end customers. Big producers opt for a strategy of outsourcing logistic services, especially storage, delivery, and distribution services to end-customers. Commitment to the strategy of outsourcing, at the same time, is the strategy of focus on the core business. Small producers, especially manufacturers of agricultural food products, have recently opted to avoid intermediaries in the transport and distribution of the product to the end customer. All in order to increase the quality of their own products and increase the competitiveness by eliminating the costs of intermediaries in transport and distribution. This is achieved by merging and shortening the supply chain. The EU has established an institutional framework regulating the operations of producers through a short supply chain. The market situation requires further optimization by producers due to lack of labour and the need to increase competitiveness and leads to the emergence of a reversible supply chain phenomenon. In the paper, the author, by applying general and special scientific methods of cognition, explores the advantages and shortcomings of the short and reversible supply chain, derived from the traditional and modern supply chain model.

This article is focused on a sub domain of quality, namely, quality of service. Considering supply chain management, the authors believe that it is important to distinguish between a quality of product (also service) offered by producers and service providers and a quality of service which is achieved between any supplier and customer, not only a consumer, along a supply chain. Quality of product represents producer’s/service provider’s commitment and is subject of various quality certificates issued by inspection authorities. This research examines the quality of service, which is provided by a supplier to its customer along the supply chain, between any pair of chain elements fulfilling this relation, including the common retailer-consumer relation. The authors introduce measurement points into a consumer-centric supply chain model for the defined criteria and defined the method of their monitoring and overall supply chain quality of service evaluation. Finally, the authors assess the envisaged impact of the results of their measurements on supply chain excellence, providing management with an opportunity to identify weak spots.

This research aimed to understand the flow of fish commodity, information, and financial in the fish supply chain at the traditional market, through case study in the Beringharjo market Yogyakarta. Data was collected through systematic interview with 18 fish businesspersons and observation on the study site. The study showed fish commodities in the market consisted of marine, freshwater and processed fish (salted/dried fish and soft bone milkfish/bandeng presto). The fish majorly supplied by suppliers from outside Yogyakarta, that reached 86-90% for fresh fish (marine and freshwater) and 100% for salted fish and raw material of bandeng presto. Suppliers and traders in Beringharjo market used flexible methods of payment, such as manual receipt and trust-based relation (for instance pay on other day). The suppliers and traders had been work together for more than five years. The emerging problems were the lack of fresh fish supply and the low quality of processed fish. The supply chain model for fresh fish involved three stages (supplier-seller-ultimate customer/household) and the supply chain model for processed fish in four stages (supplier-wholesaler-trader/seller-ultimate consumer). The supply chain model for the milkfish also consisted of four stages (supplier-fish processor-seller-ultimate consumer). The study indicates the importance of improving local fish production systems to fullfill growing fish consumption in DIY.
