Modern market scenarios are imposing a radical change in the production concept, driving companies’ attention to customer satisfaction through increased product customization and quick response strategies to maintain competitiveness. At the same time, the growing development of Industry 4.0 technologies made possible the creation of new manufacturing paradigms in which an increased level of autonomy is one of the key concepts to consider. Taking the advantage from the recent development around the semi-heterarchical architecture, this work proposes a first model for the throughput control of a production system managed by such an architecture. A cascade control algorithm is proposed considering work-in-progress (WIP) as the primary control lever for achieving a specific throughput target. It is composed of an optimal control law based on an analytical model of the considered production system, and of a secondary proportional-integral-derivative controller capable of performing an additional control action that addresses the error raised by the theoretical model’s. The proposed throughput control algorithm has been tested in different simulated scenarios, and the results showed that the combination of the control actions made it possible to have continuous adjustment of the WIP of the controlled production system, maintaining it at the minimum value required to achieve the requested throughput with nearly zero errors.

现代市场场景正在对生产理念进行根本性的改变，通过增加产品定制和快速响应策略来保持竞争力，促使公司关注客户满意度。与此同时，工业 4.0 技术的不断发展使得新的制造范式的创建成为可能，其中提高自主性是需要考虑的关键概念之一。利用最近围绕半分层架构的发展，这项工作提出了第一个模型，用于由这种架构管理的生产系统的吞吐量控制。提出了一种级联控制算法，将在制品 (WIP) 作为实现特定吞吐量目标的主要控制杠杆。它由基于所考虑的生产系统的分析模型的最优控制律和能够执行附加控制动作的二级比例积分微分控制器组成，以解决理论模型引起的误差。所提出的吞吐量控制算法已经在不同的模拟场景中进行了测试，结果表明控制动作的组合使得对受控生产系统的 WIP 进行连续调整成为可能，将其保持在实现目标所需的最小值。请求的吞吐量几乎为零。以及能够执行额外控制动作的二级比例积分微分控制器，以解决理论模型引起的误差。所提出的吞吐量控制算法已经在不同的模拟场景中进行了测试，结果表明控制动作的组合使得对受控生产系统的 WIP 进行连续调整成为可能，将其保持在实现目标所需的最小值。请求的吞吐量几乎为零。以及能够执行额外控制动作的二级比例积分微分控制器，以解决理论模型引起的误差。所提出的吞吐量控制算法已经在不同的模拟场景中进行了测试，结果表明控制动作的组合使得对受控生产系统的 WIP 进行连续调整成为可能，将其保持在实现目标所需的最小值。请求的吞吐量几乎为零。
