The primary aim of this paper is to explore theoretical and practical aspects of the soft system methodology (SSM) and simulation combination as a multi-paradigm multi-methodology approach through action research. The important theoretical findings from a systematic literature review show that previously published researches have mainly applied SSM to structure contents of messy problems and for model building. We identified two types of combination designs: (i) simulation enhancement and (ii) mixed methods. To further investigate the practical aspects of combined methodologies, we apply SSM in the conception phase of agent-based modelling to an Iranian upstream oil and gas company. We show that a combined model offers the following advantages: It (i) improves our understanding of the problem, (ii) reflects upon the modelling process, (iii) provides learning for interveners and (iv) enables the proposition of technically sound, systematically feasible and culturally desirable agreed solutions for improving the situation.

结合软系统方法和基于代理的多方法建模仿真

本文的主要目的是通过行动研究探索软系统方法论（SSM）和仿真组合作为多范式多方法论方法的理论和实践方面。系统文献回顾的重要理论发现表明，以前发表的研究主要将 SSM 应用于结构混乱问题的内容和模型构建。我们确定了两种类型的组合设计：（i）模拟增强和（ii）混合方法。为了进一步研究组合方法的实际方面，我们在基于代理的建模的概念阶段将 SSM 应用于伊朗上游石油和天然气公司。我们表明，组合模型具有以下优点：它（i）提高了我们对问题的理解，（ii）反映了建模过程，
