The relationship between CIS and CIC with new product performance is also examined. Hypotheses were tested using survey data gathered from 155 manufacturing firms in China and were analysed using partial least squares regression. Long-term orientation is positively related to using both CIS and CIC, but trust is only related to using CIS. We expected that the relationships of trust and long-term orientation would be stronger when CIC was used compared to CIS, but this was not supported. Further, CIS, but not CIC, is positively related to product performance. Future research should explore development processes, capabilities, and product characteristics better to understand the use of and outcomes from CIC. Journal: Int.

Abstract: This paper examines a supply chain comprising an online marketplace retailer, an authentic manufacturer, and a counterfeit manufacturer. The counterfeit manufacturer sells its products through agency selling. The authentic manufacturer chooses between wholesaling and agency selling where the revenue share is stipulated by the retailer. I study how the presence of counterfeits and how a retailer's profit maximisation objectives impact the authentic manufacturer's choice of contracts, decisions, and profits. I find that when the number of committed consumers to authentic products is low, the cost of counterfeits is low, the perception of counterfeits among uncommitted consumers is high, and quality is cost-efficient, wholesaling tends to be a better choice for the authentic manufacturer. However, if the retailer factors in revenue from counterfeits, the role of wholesaling in ensuring authenticity may be significantly diminished. Journal: Int.

This paper proposes a fuzzy possibilistic programming model for designing a multi-echelon reverse logistics network to optimise return management under uncertainty from returned demand, transportation and inventory costs. The model determines the optimal number and location of facilities, material flow and inventory level. Finally, a case study is conducted on an e-commerce business in Vietnam to evaluate the model's effectiveness. The network includes 36 collection sites, six intermediate warehouses and a regional hub with many convenience stores serving as collection centres. Sensitivity analyses on pertinent parameters have been performed to provide valuable managerial insights. Using the fuzzy model with a confidence level of 90%, the total cost is 326,281.6 USD, while the deterministic model generated a total cost of 361,004.5 USD. As a result, our model is efficient in providing solutions for enhancing business performance. Journal: Int.

It will also evaluate the relationship between these practices and different levels of operational performance. Data collection for the study was done by surveying 217 employees of the modern retail sector in Bangladesh. Data analysis was done through structural equation modelling, which explored the relation of operational performance with the various components GSCM, for example, internal environmental management, green purchasing, and green information systems. According to the study, GSCM procedures have a positive and robust correlation with operational performance. For owners and managers to get the most out of their operations, they need to think about green buying, green information systems, and internal environmental management all at once. This study explores the viewpoints of developing countries, contributing to the body of knowledge on green supply chain operations and performance in modern trade. Journal: Int.

This approach allows for the representation of binomial daily demand and geometrically distributed lead time, capturing various demand patterns, including smooth, intermittent, or rare occurrences. The study provides a comprehensive mathematical derivation of the closed-form expression for the steady-state probabilities of on-hand inventory levels. This leads to concise and exact formulations for key performance measures such as the average inventory level, inventory cycle length, stock-outs per cycle, and fill rate. Notably, the proposed estimator for the average inventory level shows improved accuracy over existing formulas. Finally, some numerical examples are provided to demonstrate the effectiveness of the proposed modelling approach. Journal: Int.
