The Process System Engineering community has an extensive knowledge and skills on supply chain design: from the time dimension (production and flow planning) to the space dimension (geographic position of facilities). Nevertheless, supply chains are also social networks where multiple stakeholders have to collaborate while they have different, and sometimes, diverging objectives. For this reason, having a more realistic model representing collaboration between the various stakeholders involved is necessary and new methods that facilitate the development of a shared representation of the system must be introduced. We propose to import a participatory method, PARDI (Problematic, Actors, Resources, Dynamics and Interactions), from the Socio-Environmental System community to the practices of the Process System Engineering community. Based on this method, we develop a participatory process in order to collect the necessary knowledge on the supply chain and its context. Following this participatory process, we then develop an Agent-Based Model as a simulation and decision making tool to support collective scenario analyses and collectively draw solutions with stakeholders. Our participatory modeling approach necessarily imposes a multi stakeholders vision (within the modeling but also in the result analyses) and therefore the search for a modeling consensus. Thus, it brings a better inclusion of social aspects in problem solving which are usually poorly considered leading to implementation failure sometimes. By comparing our approach with the classic one of the Process Systems Engineering community, we highlight the strengths and weaknesses of both and how complementary they can be. A case study on the already existing supply chain of the chestnut wood in Cévennes area (France) illustrates the capabilities of our participatory methodology. It focuses on the socio-economic model design of the first two steps (forestry activities to harvest) in the supply chain as the latter is locked because of economic and social organisation issues. The objective is to find the best action levers to unlock the resistance that forest plot owners have to remove declining wood from their land.

过程系统工程社区在供应链设计方面拥有广泛的知识和技能：从时间维度（生产和流程规划）到空间维度（设施的地理位置）。然而，供应链也是社交网络，多个利益相关者必须在其中进行协作，同时他们的目标不同，有时甚至是不同的目标。出于这个原因，有一个更现实的模型来表示所涉及的各个利益相关者之间的协作是必要的，并且必须引入促进系统共享表示的开发的新方法。我们建议将参与式方法 PARDI（问题、参与者、资源、动态和交互）从社会环境系统社区导入到过程系统工程社区的实践中。基于这种方法，我们开发了一个参与式流程，以收集有关供应链及其背景的必要知识。在这个参与过程之后，我们开发了一个基于代理的模型作为模拟和决策工具，以支持集体情景分析并与利益相关者共同制定解决方案。我们的参与式建模方法必然会强加多利益相关者的愿景（在建模中，也在结果分析中），因此寻求建模共识。因此，它在问题解决中更好地包含了社会方面，这些方面通常被考虑得很差，有时会导致实施失败。通过将我们的方法与过程系统工程社区的经典方法进行比较，我们强调了两者的优势和劣势以及它们的互补性。对塞文地区（法国）现有板栗木材供应链的案例研究说明了我们参与式方法的能力。它侧重于供应链中前两个步骤（林业活动到收获）的社会经济模型设计，因为后者因经济和社会组织问题而被锁定。目标是找到最佳的行动杠杆，以解除林地所有者必须从他们的土地上移除衰退木材的阻力。它侧重于供应链中前两个步骤（林业活动到收获）的社会经济模型设计，因为后者因经济和社会组织问题而被锁定。目标是找到最佳的行动杠杆，以解除林地所有者必须从他们的土地上移除衰退木材的阻力。它侧重于供应链中前两个步骤（林业活动到收获）的社会经济模型设计，因为后者因经济和社会组织问题而被锁定。目标是找到最佳的行动杠杆，以解除林地所有者必须从他们的土地上移除衰退木材的阻力。
