Abstract:T his study investigates the value of a supplier sharing information about the quality-distribution (i.e., dimensional mean or variance) of components with an assembler who matches such parts with the selective assembly of an intermediary component. Selective assembly is a strategy that is widely used by high-precision manufacturing companies to gain a competitive advantage in product quality. The use of inexpensive intermediary components (e.g., bearings) to ensure that all mating components are matched with … Show more
“…Information about both and values was more valuable for FBSA than information about only , which in turn was more valuable than information about only . Clottey and Benton (2020) obtained a similar result in a different selective assembly context, when the focus was safety‐stock reduction due to shared information. The current study indicates that this result also applies to FBSA with matchable degree as a criterion.…”

“…To determine the benefit of receiving information about , , or both from the RB supplier, we adopted a Bayesian lens. A Bayesian approach to evaluating the impact of shared information has a firm grounding in statistical decision theory (Raiffa and Schlaifer 1959) and has likewise been employed in other studies (Clottey and Benton 2020, Eppen and Iyer, 1997, Milner and Kouvelis 2002) involving the effect of shared information on predicted quantities. In this study, we want to evaluate the impact of shared information, vs. using just historical data, to estimate the mean and/or variance of incoming part dimensions.…”

“…Additionally, we found that such information becomes more valuable for reducing mismatches if existing tolerances are loosened. While Clottey and Benton (2020) employed a more reactive approach by adapting safety-stock to manage quality in a selective assembly context, the current approach can be described as a proactive one in which information sharing and design techniques are used instead.…”

F ixed-bin selective assembly (FBSA) is a method for producing high-tolerance specification assembly from lower precision components. This study investigates the design tolerance implications of an external supplier sharing dimensional information about shipped parts to be used for FBSA. An approach for reducing surplus components in FBSA is to predictively adjust the assembler's manufacturing process so that components produced internally better match those of incoming parts. However, it is unclear how the assembler's use of timely dimensions information-that is fully shared or is shared for a limited period, about the mean, variance, or both-of an externally sourced mating part would influence procedures for setting tolerances in an FBSA context. We develop and evaluate a Bayesian prediction-based model with estimated parameters from a US assembler of bearings. Our results indicate that adjustments made using predictions from solely historical data produced comparable assembly efficiency to those made with shared information about only the dimensional variance of incoming parts. Prediction-based adjustments, when only information about the dimensional mean was shared, yielded comparable matchable degrees to that when the mean and variance were both known. Furthermore, contrary to convention, looser tolerances were required to increase selective assembly efficiency. The shared information had a larger effect on the matchable degree than the modification of design tolerances in the absence of such information sharing. The insights have implications for coordinated component design and quality control.

“…An extensive review of this stream of literature can be found in Guan and Chen (2015). Arya et al (2014), Clottey andBenton (2020), andGuan et al (2020) also consider the disclosure and sharing of quality information. Kuksov and Lin (2010) develop a game-theoretic model and examine the interaction of information provision, product quality, and pricing decisions by competitive firms.…”
In a two‐stage supply chain comprising a manufacturer and a retailer selling secondhand products and new products, we incorporate the manufacturer's channel decisions to examine the retailer's quality disclosure strategy of secondhand products. The quality disclosure of secondhand products may or may not be implemented, but the direct channel is always introduced. Interestingly, the retailer withholds (discloses) information of secondhand products with sufficiently high quality when it is lower (higher) than consumers' acceptance of direct channel in dual‐channel structure. If the secondhand product quality is lower than consumers' direct channel acceptance, the quality is disclosed only when it is medium.
