Abstract: Achieving a high quality product corresponding consumer requirements involves organizing and supporting the production process with a suitable and flexible logistics process. The more the process/ production flow is better organized, divided into subdomains (production, maintenance, quality), each with clearly defined indicators and responsibilities, the more the process will be stable, easier to follow and to intervene on perturbations that can appear. In a stable system, disturbance variables can be controlled, thus losses can be reduced. Everybody is looking for "the optimal process", "best method" that would remove the uncertainty, ambiguity, defect, doubt and error. This study aims to present ways of correcting the uncertainties arising in production systems through standardization, communication, waste awareness, efficient logistics, states incertitude interpretation, analysis and performance indicators, applying neutrosophy theory, because a product that has several options increases the grade of uncertainty in the manufacturing process.
