Abstract
When printing orders change, the reconfigurable printing manufacturing system (RPMS) needs to be reconfigured, which produces many feasible reconfiguration schemes. To find the optimal reconfiguration scheme and verify its integrity, an operation chain model (OCM) of an RPMS is proposed to describe the operating process of an RPMS. First, a comprehensive evaluation algorithm considering both subjective and objective evaluation probabilities is designed by analyzing the characteristics of the printing production process. Then, the syntax of stochastic process algebra is conservatively extended to meet the operation chain's specifications. The syntax and transition rules of the OCM are defined and the semantic model of the operation chain is constructed. Finally, we carried out experiments on the RPMS of a printing enterprise and provide the experimental results. The results show that the optimal printing scheme that is selected by the OCM is in line with expectations. In addition, the measurement result I CP = true shows that the optimal reconfigurable printing scheme process has good integrity.

Summary
With the continuous improvement of living standards and technology, people tend to customize and diversify products. The reconfigurable printing manufacturing system (RPMS) has this capability. The existing RPMS cannot make decisions on the optimal reconfiguration printing scheme, and it cannot verify the integrity of the system’s functions. Based on basic process algebra, stochastic process algebra (SPA) adds some performance characteristics such as time and probability. We propose a comprehensive evaluation method considering both subjective and objective evaluations to calculate the probability of selecting the optimal reconfiguration scheme. This paper takes the RPMS as the research object and studies its optimal printing scheme and integrity based on SPA.
