Summary: This study aims to investigate the factors influencing passenger loyalty in Indonesian low-cost carriers, including service quality, price, customer satisfaction, and perceived value. Quantitative methods were employed, and a survey was conducted on 313 Indonesian respondents using online questionnaires. The results, analyzed through LISREL structural equation modeling, confirm 4 hypotheses and reject 3 hypotheses. The findings indicate that consumer behavior exhibits atypical manifestations in the context of Indonesian consumers, where good service quality does not necessarily lead to increased satisfaction and lower prices do not necessarily result in increased satisfaction. Additionally, this study emphasizes the significance of consumer loyalty for the survival of low-cost carriers in the market.

Summary: This study presents a supply chain model with a manufacturer and a retailer facing customer returns, where the manufacturer is uninformed about the returns rate. The manufacturer has different strategies to acquire returns rate information, while the retailer may benefit from certain strategies but is always worse off from the manufacturer's channel encroachment strategy. Both the manufacturer and the retailer may have consistent preferences regarding the manufacturer's strategy.

Summary: This paper investigates the dynamical behaviors of the classical dual-channel supply chain from the perspective of fractal theory. The definition of filled Julia set in supply chain price competition model is introduced, and it is divided into several sub basins based on the periodicities of the attractors. The importance of mixed coexisting attraction basins' connectivity is illustrated. The inner characteristics of filled Julia sets under different online preferences are analyzed, indicating the negative influence of online preference increase on filled Julia sets' structures. Three control strategies are adopted for unstable cases caused by high online preference, and their control effects are analyzed by quantifying the connectivity restorations.

Summary: This study uses a game theoretical model to examine the supply strategy of manufacturers in response to retailers introducing store branded products with lookalike packaging. The findings suggest that manufacturers will supply store branded products to retailers when the production cost is low or the in-house cost is high, leading to consumer confusion and a win-win situation. The proportion of confused consumers has a non-monotone effect on the profitability of both the retailer and manufacturer. The study's results remain robust under various scenarios.

Summary: This paper examines competition and cooperation strategies in pricing and green marketing in a dual-channel supply chain, taking into account customer satisfaction. The study finds that the optimal price is not always proportional to green marketing efforts due to the influence of customer satisfaction. In some cases, the manufacturer should actively assist retailers in improving green marketing to increase profits.

Summary: In multitier supply chains, the selection of exclusive channel strategies becomes a critical decision for brand owners, resulting in three typical structures. This study formulates these structures in a three-tier supply chain and considers observable and unobservable contracts. It builds game-theoretical models and finds that the exclusive retailing channel is more beneficial for brand-owners, regardless of the contract observability. The level of channel substitutability and contract unobservability also have significant effects on brand owners' performance.

Summary: This study examines the brand promotion strategies of retailers in a competitive model and investigates the decision model and equilibrium outcomes of stakeholders under supply uncertainty. The results show that retailers are less likely to promote product brands when the promotion cost is high, but more likely to do so when the cost is low. When the promotion cost matches market expansion, only one retailer will promote the product brand. Supply uncertainty diminishes retailers' affordability and motivation to promote product brands, but reduces the likelihood of them being in a prisoner's dilemma. Additionally, market expansion improves social welfare while supply uncertainty diminishes it.

Summary: This study investigates the optimal selection strategy of green product R&D and its impact on prices, green levels, and enterprise profits in a competitive supply chain. The study identifies three types of green product R&D strategies and finds that price competition intensity and green R&D cost negatively affect these variables. The research results provide insights for the strategic choice of green product R&D in competitive supply chains.

Summary: This paper examines the optimal financial hedging strategy and sustainable development in four different supply chain structures. It proposes the use of an index-based price contract to transfer risk from manufacturers to downstream retailers and achieve risk-sharing in the supply chain. The study discusses the optimal hedging strategy and the level of product sustainability in monopoly, monopoly with Nash bargaining, retailer competition, and manufacturer competition structures. The findings suggest a positive relationship between the hedge ratio and consumer preference for green products, while it is inversely related to green product research and development costs. Notably, in a manufacturer competition supply chain, slight fluctuations in input commodity prices significantly increase the profits of both manufacturers, but as the fluctuations continue to increase, one manufacturer's profit declines while the other's rises slowly. Furthermore, competition based on product sustainability negatively impacts manufacturers' and retailers' profits and reduces the overall level of sustainability.

Summary: In a modern supply chain, the quality of the final product depends on the joint efforts of multiple firms. Traceability technologies, such as blockchain, can enable affordable supply chain traceability. This study investigates the impact of traceability on a two-echelon supply chain, finding that it can decrease the supplier's quality effort while weakly increasing their profit, and also weakly decreasing the buyer's profit. However, the total profit of the supply chain can be increased with the presence of traceability.

Summary: This study analyzes the optimal supply quality and price subsidy strategies of producers and sellers in the agricultural supply chain. The findings suggest that centralized control decision can effectively improve the quality and safety of agri-foods as well as the overall profit of the supply chain. Additionally, quality improvement actions driven by demand-side consumption are more effective than those driven by supply-side producers.

Summary: The Connected Max-k-Cut Problem is an extension of the well-known Max-Cut Problem, where the objective is to partition a graph into k connected subgraphs by maximizing the cost of inter-partition edges. The researchers propose a new integer linear program and a branch-and-cut algorithm for this problem, and also use graph isomorphism to structure the instances and facilitate their resolution. Extensive computational experiments show that, if k > 2, their approach outperforms existing algorithms in terms of quality.

Summary: This paper studies a variant of the orienteering problem known as the clustered orienteering problem. In this problem, customers are grouped into clusters and a profit is associated with each cluster, collected only when all customers in the cluster are served. The proposed evolutionary algorithm, incorporating a backbone-based crossover operator and a destroy-and-repair mutation operator, outperforms existing algorithms on benchmark instances and sets new records on some instances. It also demonstrates scalability on large instances and has shown superiority over three state-of-the-art COP algorithms. The algorithm is also successfully applied to a dynamic version of the COP considering stochastic travel time.
