Industry 4.0 proposes the incorporation of information technologies at all levels of the production process. By incorporating these technologies, Industry 4.0 provides new tools for production planning processes, allowing to address problems in an innovative and efficient manner. Then, in this work a One-of-a-Kind Production (OKP) process is approached, where the products tend to be highly customized. OKP implies to work with a very large variability within production, which demands very efficient planning systems. For this, a planning model based on CONWIP-type strategies was proposed, which seeks to level the production of a shop floor configured in the form of a job shop. In turn, different dispatching rules were proposed to study the performance and analyze the behavior of the system. From the obtained results, it is observed that, when the production demand is very exigent for the capacity of the system, the dispatching rules that analyze the workload generated by each job tend to perform better. But, when the demand on the capacity of the production system is a little less intense, the rules associated with due dates are the ones that obtain the best results
