Abstract:In order to improve the standard of management in hospitals and effectively control the cost of clinical treatments, this research primarily focuses on optimizing the scheduling of clinical pathways (CPs). A mathematical model for CP scheduling is constructed, and the hybrid genetic algorithm (HGA, combining a genetic algorithm with particle swarm optimization) is proposed for solving this problem so as to distribute medical resources and schedule the treatments of patients reasonably and effectively.

“…The majority of the hybrid methods are the combinations of different metaheuristics, such as the combination of Genetic Algorithm and Tabu Search procedures (as discussed by Zhang et al [258], Meeran and Morshed [259], Li and Gao [260], Yu et al [261], and Noori and Ghannadpour (2012)) and the integration of Genetic Algorithm and Simulated Annealing (as discussed by Safari and Sadjadi [262], Rafiei et al [263], and Bettemir and Sonmez [264]). In recent years, the combination of Genetic Algorithm and Particle Swarm Optimization (PSO) had been widely applied in both scheduling and vehicle routing problems (as discussed by Du et al [265], Yu et al [266], Liu et al [267], and Kumar and Vidyarthi [268]). Some other Genetic Algorithm-based hybrid methods were also observed in the literature, such as the hybrid Genetic-Monkey algorithm [269], hybrid Genetic Algorithm combined with the LP-relaxation of the targeted model (as discussed by Mohammad and Ghasem [270]), and the combination of Genetic Algorithm and Local Search procedure with Fuzzy Logic Control, where Fuzzy Logic Control is used to enhance the search ability of the Genetic Algorithm (as discussed by Chamnanlor et al [271]); some Pareto-based hybrid Genetic Algorithms were also developed for dealing with multiobjective problems (as discussed by Zhang et al [272] and Tao et al [273]).…”
Over the past decades, optimization in operations management has grown ever more popular not only in the academic literature but also in practice. However, the problems have varied a lot, and few literature reviews have provided an overview of the models and algorithms that are applied to the optimization in operations management. In this paper, we first classify crucial optimization areas of operations management from the process point of view and then analyze the current status and trends of the studies in those areas. The purpose of this study is to give an overview of optimization modelling and resolution approaches, which are applied to operations management.

“…Wolf [7] has proposed a mathematical programming model with constraints for clinical pathway and pointed out the difficulty of the clinical path optimization, which involved the trade-off of multiple clinical indicators. Other researchers [8][9][10][11] have introduced hybrid genetic algorithm into clinical pathway scheduling to optimize the execution of the routine diagnostic activities, which has only considered the local human resources constraints and mainly been for single or multiple clinical pathway scheduling in specific departments. Aiming to…”
Abstract-The clinical pathway execution is a complex system engineering related to multidisciplinary or multi-department collaboration such as examination, laboratory test, operation, nursing, etc. This paper has proposed a multi-agent based simulation method from the hospital system level, and some key technologies including simulation model specification for hospital system, patient behavior model specification based on clinical pathway, and the multi-agent simulation model scheduling mechanism are discussed.

“…Health-care organizations seek for a better control of their medical services not only to satisfy treatment requirements but also to leverage cost-saving opportunities through standardization of treatment behaviors in clinical pathways (CPs) [1][2][3][4][5][6]. With this respect, compliance checking is important as it ensures that treatment behaviors of a healthcare organization act in accordance with the established CP specifications [7].…”
Compliance checking for clinical pathways (CPs) is getting increasing attention in health-care organizations due to stricter requirements for cost control and treatment excellence. Many compliance measures have been proposed for treatment behavior inspection in CPs. However, most of them look at aggregated data seen from an external perspective, e.g. length of stay, cost, infection rate, etc., which may provide only a posterior impression of the overall conformance with the established CPs such that in-depth and in near real time checking on the compliance of the essential/critical treatment behaviors of CPs is limited. CP specification and support online compliance checking, this article presents a semantic rule-based CP compliance checking system. In detail, we construct a CP ontology (CPO) model to provide a formal grounding of CP compliance checking. Using the proposed CPO, domain treatment constraints are modeled into Semantic Web Rule Language (SWRL) rules to specify the underlying treatment behaviors and their quantified temporal structure in a CP. The established SWRL rules are integrated with the CP workflow such that a series of applicable compliance checking and evaluation can be reminded and recommended during the pathway execution. The proposed approach can, therefore, provides a comprehensive compliance checking service as a paralleling activity to the patient treatment journey of a CP rather than an afterthought. The proposed approach is illustrated with a case study on the unstable angina clinical pathway implemented in the Cardiology Department of a Chinese hospital. The results demonstrate that the approach, as a feasible solution to provide near real time conformance checking of CPs, not only enables clinicians to uncover non-compliant treatment behaviors, but also empowers clinicians with the capability to make informed decisions when dealing with treatment compliance violations in the pathway execution.
