To model this type of distributionally robust contract design problem, the Wasserstein ambiguity set is employed to characterize the ambiguous multi-output probability distribution. Two decision criteria are adopted by the principal to evaluate the designed robust contract under partial distribution information, the first is the worst-case expected criterion, and the second is the worst-case risk criterion. Furthermore, the concept of distributionally robust incentive compatibility is defined with respect to a pair of ambiguity sets. In virtue of two decision criteria, this paper develops a new reward-risk distributionally robust contract design model as well as its extension models based on different risk measures and globalized distributionally robust incentive compatibility condition. The distributionally robust counterpart and globalized distributionally robust counterpart problems of the developed distributionally robust contract design models are linear programming or mixed-integer linear programming models. According to the structural characteristic of the resulting mixed-integer linear programming model, a new tailored Benders decomposition algorithm is designed. At the end of this paper, an inventory decision with backorder problem is addressed and some numerical experiments are performed to demonstrate the influences of three risk measures on robust optimal contracts. The computational results demonstrate that the developed distributionally robust contract design models can facilitate the principal to make the informed contract decisions.</div></div>","PeriodicalId":10542,"journal":{"name":"Computers & Operations Research","volume":"180 ","pages":"Article 107061"},"PeriodicalIF":4.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759494","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Notably, the Operating Room Scheduling Problem (ORSP) is prominent in literature due to its substantial cost and revenue implications. ORSP is structured into three hierarchical decision levels: strategic, tactical and operational, with higher-level decisions influencing subsequent ones. While most studies focus on single decision levels, there has been a growing interest in integrated models, as these offer a more holistic view and often result in better outcomes, despite their complexity of resolution. Although various literature reviews have explored different aspects of ORSP, few have focused on models integrating multiple decision levels. This study addresses that gap by systematically reviewing the literature focusing on contributions presenting mathematical programming models and optimization algorithms that simultaneously address multiple decision levels of the ORSP. Following the PRISMA 2020 protocol, the review spans works published until October 2024, totaling 46 articles. It outlines objectives, characteristics, solution approaches, and identifies gaps in literature.

This paper addresses these characteristics by studying the identical parallel machine scheduling problem, aiming to minimize total weighted tardiness under constraints of arbitrary release times and multiple machine unavailability periods. To address this research problem, a decoding mechanism based on machine idle periods is first proposed, effectively solving the impact of machine unavailability periods on the scheduling scheme. Secondly, a multi-population cooperative evolutionary algorithm is designed in which the mechanisms of selection, crossover, mutation, and information exchange between populations are improved. The optimal scheduling properties of two jobs on the same machine and different machines are analyzed, resulting in the design of two local search mechanisms. Additionally, Q-learning is introduced to enhance the adaptability of algorithm parameters by dynamically adjusting them within the multi-population cooperative evolutionary algorithm, resulting in a Q-learning-driven multi-population cooperative evolutionary algorithm with local search (Q-MPCEA-LS). Finally, comparative experiments between the Q-MPCEA-LS algorithm and various metaheuristic algorithms are conducted. The experimental results show that, across all instances, the average relative error in the average value metric of the Q-MPCEA-LS algorithm is 40.0%, 0.1%, 44.2%, and 75.9% lower than that of Q-MPCEA-LS without local search, Q-MPCEA-LS without Q-learning-based dynamic parameter adjustment, the iterative hybrid metaheuristic algorithm, and the hybrid genetic immune algorithm, respectively. These results validate the effectiveness of the individual components and the overall effectiveness of the Q-MPCEA-LS algorithm.</div></div>","PeriodicalId":10542,"journal":{"name":"Computers & Operations Research","volume":"180 ","pages":"Article 107076"},"PeriodicalIF":4.1,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since scheduling problems have discrete search spaces with complex constraints, metaheuristic algorithms are commonly used by a notable number of researchers and practitioners. Although these algorithms do not guarantee optimality, they offer notable opportunities. Moreover, employing machine learning methods in such algorithms draws significant attention due to their promising capabilities such as learning patterns out from data for autonomous decision-making. Accordingly, this study introduces an Iterated Greedy Search algorithm enhanced by Q-learning method. In this regard, a new state evaluation method so as to process inputs in an aggregated fashion is proposed first. Different modifications of this function are adopted by two distinct Q-learning mechanisms. Accordingly, the proposed method autonomously tunes both algorithm parameters and local search procedures. Secondarily, a cloud-integrated scheduler adopting the proposed method is developed as a prototype model. Thus, information derived out from data can be shared among devices and plants at any location. The proposed strategy is tested on a hybrid flexible flowshop scheduling problem with sequence-dependent setup times and release times, which has numerous applications in industry. The performance of the proposed approach is compared to a number of well-regarded and commonly used algorithms. In this context, synthetic problem data is used first. Subsequent to demonstration of the superiority of the proposed approach in these problems and conducting comparisons with CPLEX solver, it is tested on production data.

Location modeling too is central in addressing sustainability, resilience, efficiency and effectiveness across a range of urban and environmental contexts. Over the past three decades geographic information systems, and more generally GIScience, has emerged as a critical complement to location modeling. This paper seeks to articulate and demonstrate how GIScience is now a central component of location modeling, one that fundamentally bridges geographic information systems and optimization in many ways. GIScience primitives are formally structured and specified in order to make linkages explicit in the context of location modeling.
