This work is devoted to the study of the Uncertain Quay Crane Scheduling Problem (QCSP), where the loading /unloading times of containers and travel time of quay cranes are considered uncertain. The problem is solved with a Simulation Optimization approach which takes advantage of the great possibilities offered by the simulation to model the real details of the problem and the capacity of the optimization to find solutions with good quality. An Ant Colony Optimization (ACO) meta-heuristic hybridized with a Variable Neighborhood Descent (VND) local search is proposed to determine the assignments of tasks to quay cranes and the sequences of executions of tasks on each crane. Simulation is used inside the optimization algorithm to generate scenarios in agreement with the probabilities of the distributions of the uncertain parameters, thus, we carry out stochastic evaluations of the solutions found by each ant. The proposed optimization algorithm is tested first for the deterministic case on several well-known benchmark instances. Then, in the stochastic case, since no other work studied exactly the same problem with the same assumptions, the Simulation Optimization approach is compared with the deterministic version. The experimental results show that the optimization algorithm is competitive as compared to the existing methods and that the solutions found by the Simulation Optimization approach are more robust than those found by the optimization algorithm.

Halal supply chain management, with its focus on Islamic values in tourism, is increasingly recognized for enhancing destination competitiveness and visitor satisfaction. This study examines how Islamic attributes, motivations, and norms influence visitor satisfaction and word of mouth in Medan City's tourism sector. In the halal tourism industry, supply chain management plays a crucial role in ensuring that every stage from procurement, production, distribution, to service delivery complies with halal standards. The research aims to evaluate the impact of Islamic Physical Attributes, Islamic Non-Physical Attributes, Push Motivation, Pull Motivation, and Islamic Norms on visitor satisfaction and their subsequent effect on word of mouth. By employing a quantitative approach, the study utilizes structured questionnaires based on previous research and applies Structural Equation Modeling (SEM) for analysis. Data were collected from 300 tourists in Medan City, including both local and international visitors. The study finds that Islamic Non-Physical Attributes and Pull Motivation significantly enhance visitor satisfaction. Islamic Physical Attributes also positively affect satisfaction, while Push Motivation does not. Satisfaction strongly influences word of mouth, but Islamic Norms negatively moderate this relationship. Islamic attributes and motivations play a crucial role in shaping visitor satisfaction in the tourism context. Islamic norms, however, may complicate the satisfaction-word of mouth link. The implementation of effective halal supply chain management can ensure that all aspects of supply chain management in halal tourism, from products to services, meet the expected halal standards. Practically, destination managers should emphasize Islamic attributes and motivational factors to improve visitor satisfaction. Theoretically, the study contributes to understanding the complex dynamics between satisfaction, norms, and word of mouth in halal tourism.

The objective of this study is to assess the joint effect of corporate entrepreneurship (CE) and supply chain management (SCM) strategies on firm performance in the circumstance of Saudi Arabian manufacturing firms. This is interesting in the sense that while previous scholars have focused on CE and SCM separately, the combinative aspect of the two particularly in nonwestern countries seems still to be short of attention. In this respect, this paper attempts to apply a resource-based view and suggest that CE and SCM complement each other and in the end performance of the firm will be increased. Out of the 84 Saudi manufacturing firms covered in the structured survey, data was analyzed using Ordinary Least Squares (OLS) regression. The results indicate that CE, particularly dimensions such as new business venturing, product innovation, technological entrepreneurship, mission reformulation, reorganization and system-wide changes, significantly enhances firm performance. Additionally, SCM strategies were found to have a positive and statistically significant impact on firm performance, highlighting the critical role of effective supply chain management in operational efficiency and competitive positioning. The findings contribute to the literature by providing empirical evidence from a Middle Eastern context, thereby enhancing the generalizability of existing theories on CE and SCM. The study also offers practical implications for managers and policymakers, suggesting that aligning CE initiatives with SCM strategies can drive sustained competitive advantage. These insights are particularly relevant for firms operating in emerging markets, where economic reforms and diversification efforts, such as Saudi Arabia's Vision 2030, necessitate strategic innovation and supply chain optimization.

Designing a production process normally is involved with some important constraints such as uncertainty, trade-off between production costs and quality, customer’s expectations and production tolerances. In this paper, a novel multi-objective robust optimization model is introduced to investigate the best levels of design variables. The primary objective is to minimize the production cost while increasing robustness and performance. The response surface methodology is utilized as a common approximation model to fit the relationship between responses and design variables in the worst-case scenario of uncertainties. The target mean ratio α is applied to ensure the quality of the process by providing the robustness for all types of quality characteristics and with a trade-off between variability and deviance from the ideal point. The Lp metric method is used to integrate all objectives in one overall function. In order to estimate target value of the quality loss by considering production tolerances, the process capability ratio (Cpm) is applied. At the end, a numerical chemical mixture problem is served to show the applicability of the proposed method.
