Change control is considered as the prime power and obstruction of growth. During product research and development, it is difficult to avoid various engineering changes (ECs). Appropriate control of ECs can improve the design and quality of products. This study examines aerospace products from development to production over 17 years including 1180 cases of EC. We use statistical methods to analyze the central and dispersion tendency of the products research and development and then test it to find which key capability factors are important to EC. Some required ECs for a typical aerospace product development are investigated. In this study, key factors for aerospace products are classified into nine categories: Structure, subsystem, electrics, control, electronics, interface, manufacture, engine and others. The results show that the life cycle of electronic parts and time to implement ECs is four to seven years and the electronics manufacturer must improve risk management in product research and development stages to reduce engineering changes effectively. Further, a regression model is developed to recompose integrated planning for controlling the cost and scheduling. Thus, the communication of various designs and the control of ECs can be improved in the initial stages of product research and development.

Conventional methods for assessing the quality of components mass produced using injection molding are expensive and time-consuming or involve imprecise statistical process control parameters. A suitable alternative would be to employ machine learning to classify the quality of parts by using quality indices and quality grading. In this study, we used a multilayer perceptron (MLP) neural network along with a few quality indices to accurately predict the quality of “qualified” and “unqualified” geometric shapes of a finished product. These quality indices, which exhibited a strong correlation with part quality, were extracted from pressure curves and input into the MLP model for learning and prediction. By filtering outliers from the input data and converting the measured quality into quality grades used as output data, we increased the prediction accuracy of the MLP model and classified the quality of finished parts into various quality levels. The MLP model may misjudge datapoints in the “to-be-confirmed” area, which is located between the “qualified” and “unqualified” areas. We classified the “to-be-confirmed” area, and only the quality of products in this area were evaluated further, which reduced the cost of quality control considerably. An integrated circuit tray was manufactured to experimentally demonstrate the feasibility of the proposed method.

Abstract Tag ownership transfer is an important process for RFID system. Besides the user needs to obtain the information concerning the quality of products in some scenarios, which are attached by tags. In this paper, we proposed an ownership transfer protocol with retrospective ability and analyzed its security level by using GNY logic. The results indicate that the ownership transfer protocol provides high-quality security to RFID systems. It provides an authentication between the tag and owners and location privacy of the tag. The protocol enables to resist a replay attack, man-in-the-middle attack and desynchronization attack. It also protects forward security and backward security. Moreover, it provides the information concerning the quality of the product attached by tags. We analyzed the performance of the protocol and implemented it. The results of the empirical study show that the cost time of a tag is less than some other protocols and suitable for low-cost tags.

Many firms buy cloud services from cloud vendors, such as Amazon Web Services to serve end users. One of the key factors that affect the quality of cloud services is congestion. Congestion leads to a potential loss of end users, resulting in lower demand for cloud services. Although discount can stimulate demand, its effect under congestion is ambiguous; a higher discount leads to higher demand, but it can further lead to higher congestion, thereby lowering demand. We explore how congestion moderates both cloud vendor pricing and the buyer’s fulfillment decisions. We seek to answer how the congestion sensitivity of the end users and the cost of technology impact buyer profitability and the cloud vendor’s choice of discount. We also examine how the cost of technology determines the buyer’s willingness to pass on savings to end users. Our results show that the buyer is not necessarily worse off even when the end users are more intolerant to congestion. In fact, when end users are more congestion sensitive, the demand for cloud services can sometimes increase, and the discount offered by the vendor can decrease. We also observe that a lower cost of technology can sometimes hurt the buyer, and the buyer can pass on lower benefits to end users.

In online purchasing, customers may return products due to dissatisfaction with the quality of the product, and receive a refund based on the return policy, which is determined by online distributors. Online distributors can offer generous policies to attract more customers, but at the cost of reducing total profits. In this paper, the effect of the pricing and quality of complementary products (products sold together with other items) in online selling under the return policy is investigated. For this purpose, a mathematical model is developed to obtain optimal values for selling price, refund amount, and quality of products. Based on analytical results, a solution algorithm is proposed to solve the numerical examples and perform sensitivity analysis. Findings reveal that, while increasing the sensitivity of demand with respect to the refund amount, the price, quality, and refund on returned products should be increased. In addition, the online distributor should increase the quality of products when customers are more sensitive to the quality of products. Among other results, the selling price is shown to be negatively affected by demand elasticity with respect to price. In this situation, the online distributor should reduce the quality level and the refund amount for returned products to avoid a sharp decline in profit. In addition, when the quality cost is high, the price and quality should be decreased and the refund amount unchanged.
