Quality Incentive Method For The Complex Product Supply Chain Based On The Dynamic And Static Reference Points

Complex products refer to a group of large products or systems,such as aviation systems and ships,that have high R&D costs(research and development costs),complex structures,high engineering technology content,high integration level of components,and are customized in small batches.Due to the complexity of products,the products’ quality cooperation is usually completed by multiple agents.The agents can divide into two types,main manufacturer and supplier.The supplier provides raw materials for the outsourcing product.And the main manufacturer is responsible for the process of components assembling and the product delivering.Affected by the sequence of product manufacturing,the main manufacturer probably stays in a passive position in the cooperation.Nevertheless,the main manufacturer’s psychological utility is not only affected by the quality of this delivery but also affected by the previous product’s quality,such as the industry average quality,the highest quality of previous deliveries,etc.Those factors that influence the main manufacturer’s psychological utility are defined as the quality reference points.The main manufacturer can effectively control the supplier’s behavior by combining the supplier’s payment with its psychological utility,which will result in the delivery of outsourcing components in standard quality level and the negative impacts of the project manufacturing sequence being avoided.Consequently,from the perspective of reference points,this thesis proposes a new income settlement method for the quality cooperation of the complex products,which concludes domains as follows.The quality incentive method based on the static reference point with a single batch delivery design for the supply chain quality management of the complex products.Based on the previous experience and data,without reference points,the suppliers will provide outsourcing products that meet the qualifications for opportunity benefit.With reference points,the main manufacturer tends to compare the supplier’s delivery quality with the industry average quality.Considering the psychological impact of the reference point on the main manufacturer,the suppliers will ensure the outsourcing product quality to maintain a good quality reputation.The quality equilibrium in the cooperation is calculated by constructing the goal programming model,the contract risk attitude coefficient,risk and return loss coefficient,the economic value function is adjusted to reach the maximum expected profit.This part is divided into two cases for conclusion comparison,without reference points,and with reference points.The quality incentive method based on the dynamic and static reference points in multi-batch delivery proposes for the supply chain quality management of the complex products.In the multi-batch delivery,the main manufacturer’s psychological utility is not only influenced horizontally by the industry average quality but also vertically by the highest quality in the previous delivery.Besides,after several cooperation,the main manufacturer will encourage suppliers to continually enhance the quality level with quality reward.The quality equilibrium point will be further improved.A cooperation goal programming model is proposed to calculate the maximum prospect about the quality of the equilibrium.The prospect value function concludes the economic profit and the main manufacturer’s psychological utility value.This part contains two cases,with and without quality reward.Four measures put forward to implement the new income settlement method.More specifically,first,the information database is built to provide data references for the determination of quality reference points and future cooperation.Second,an information-sharing platform between the main manufacturers is built to break the information asymmetry of the industry.The most updated industry average quality can be defined as the reference point.Thirdly,the supplier credit system in the industry is established to score each supplier in cooperation with several indicators.The main manufacturer can stay in a strong position in cooperation where the importance of quality reputation is emphasized.Fourth,quality evaluation system is established to realize collaborative quality management,which obtained a comprehensive performance index by evaluating the performance of both parties multi-dimensionally and ensures the satisfaction of both parties by combining it with the economic benefits.
