When the demand is sensitive to retail price, revenue sharing contract and two-part tariff contract have been shown to be able to\r\ncoordinate supply chains with risk neutral agents.We extend the previous studies to consider a risk-averse retailer in a two-echelon\r\nfashion supply chain. Based on the classic mean-variance approach in finance, the issue of channel coordination in a fashion supply\r\nchain with risk-averse retailer and price-dependent demand is investigated. We propose both single contracts and joint contracts\r\nto achieve supply chain coordination. We find that the coordinating revenue sharing contract and two-part tariff contract in the\r\nsupply chain with risk neutral agents are still useful to coordinate the supply chain taking into account the degree of risk aversion\r\nof fashion retailer, whereas a more complex sales rebate and penalty (SRP) contract fails to do so.When using combined contracts\r\nto coordinate the supply chain, we demonstrate that only revenue sharing with two-part tariff contract can coordinate the fashion\r\nsupply chain. The optimal conditions for contract parameters to achieve channel coordination are determined. Numerical analysis\r\nis presented to supplement the results and more insights are gained....
Mathematical models of inventory-distribution routing problem for two-echelon agriculture products distribution network are\r\nestablished, which are based on two management modes, franchise chain and regular chain, one-to-many, interval periodic order,\r\ndemand depending on inventory, deteriorating treatment cost of agriculture products, start-up costs of vehicles and so forth. Then,\r\na heuristic adaptive genetic algorithmis presented for the model of franchise chain. For the regular chain model, a two-layer genetic\r\nalgorithmbased on oddmentmodification is proposed, inwhich the upper layer is to determine the distribution period and quantity\r\nand the lower layer is to seek the optimal order cycle, quantity, distribution routes, and the rational oddment modification number\r\nfor the distributor. By simulation experiments, the validity of the algorithms is demonstrated, and the two management modes are\r\ncompared....
The remanufacturing industry as a whole and the automotive sector in particular have, over the years, proven to be\r\nbeneficial to the environment and economically lucrative to the companies involved as well as to their customers.\r\nHowever, remanufacturing is associated with complicating characteristics, not least to mention the process of core\r\nacquisition.\r\nThe automotive industry is one of the earliest adapters of remanufacturing. Parts like engines, brake calipers and\r\nservo pumps are common targets for remanufacturing. Modern cars also have several embedded computers, often\r\nreferred to as electronic control units that communicate, share information and verify each other over a Controller\r\nArea Network (CAN) bus. Due to their high value and an increasing trend in the amount of CAN bus mechatronic\r\ndevices, interest in their remanufacture is growing.\r\nPrevious research has shown that it is preferable that the remanufacturer is an original equipment manufacturer\r\n(OEM), or has a close relation to the OEM, in order to achieve a well-performing remanufacturing business. In the\r\nautomotive industry, there are many small and medium-sized enterprises (SMEs) that perform remanufacturing; for\r\nthese enterprises, the challenges to have a profitable business are even harder. This is because the OEMs will not\r\nrelease any information on the communication parameters and therefore will not support the independent\r\nremanufacturing business. As a consequence, the independent remanufacturers, often SMEs, have to perform\r\nsubstantial reverse engineering.\r\nThis paper presents a qualitative research study, based on interviews at SMEs regarding challenges linked to the\r\nreverse logistics of SMEs remanufacturing and trading used automotive mechatronic devices, to identify specific\r\nchallenges concerning the collection phase of automotive mechatronic remanufacturing. Challenges previously\r\nidentified by researchers are confirmed, additional challenges within the collection phase are recognized, and\r\nchallenges expected to arise when remanufacturing and trading automotive electronic CAN bus mechatronic\r\ndevices are identified. The major concern for the involved companies when commencing future challenges is the\r\nhandling, transportation and storing of cores. Even though the cores today mainly consist of mechanical devices,\r\nthese challenges are still present; they are expected, however, to become even more crucial when cores contain a\r\nhigher degree of mechatronic devices....
Thestudy of the logistics project evaluationmodel features reviews the traditional value evaluationmodel.On the basis of this, using\r\nthe fuzzy theory, we establish several logistics project evaluation models under fuzzy environment. The analysis of the respective\r\ncharacteristics and the comparison of the calculated results of the three models show that these models are important methods of\r\ninvestment value of logistics evaluation....
The purpose of this paper is to explore the impact of supply chain flexibility on the\r\ncompetitiveness and firm performance and to explain the role of competitiveness as mediator\r\nfor the relation between supply chain flexibility and firm performance. Methods of data collection was survey. The sample was the manager of large-scale fishery firms in the\r\nSoutheast Sulawesi. Research results showed the high supply chain flexibility has a\r\nsignificant effect on higher competitiveness, but does not has significant effect on firm\r\nperformance, there for competitiveness has significant effect on firm performance. Finally,\r\ncompetitiveness becomes a complete mediation relationship between supply chain flexibility\r\non firm performance. The practical implications of this study was to provide insight and\r\nknowledge to fishery firm managers, particularly in Southeast Sulawesi and Indonesia and\r\ngenerally in other developing countries, in implementing the concept supply chain flexibility\r\nby observing the capability of their partners in the supply chain to respond market changes in\r\nachieving and maintaining competitiveness and firm performance. Originality of this research\r\nwas to provide the basis for an integrated configuration model in testing the relationship\r\nbetween supply chain flexibility on competitiveness and firm performance, and also on the\r\nrole of competitiveness as mediator in improving firm performance....
