Abstract : The competitiveness of a company depends on its organization ability to improve the efficiency of the manufacturing process by controlling its variability while maintaining low costs, reduced delays and, sometimes, a certain capacity to produce at high volumes. Process monitoring is a set of activities performed by an operational process of control according to the control plan which is predetermined with specific goals in terms of risk control. The implementation of the control plan is often undermined by: the uncertainties associated with physical and informational flows, the interaction of the control process with other operational processes and the limitations of control resources. The objective of this thesis was to address this problem by proposing new approaches to the design of control plans. For this, we propose an approach for defining an insurance-based control plan that limits exposure to risk and optimizes control resources utilization. A simplified formalization has allowed explaining this approach through examples. The results of experiments, done on an industrial case study, demonstrate the value of the approach for operational risk management in a manufacturing process. Subsequently, a generalized formalization of the approach has been proposed to design the control plan of a generalized process with a set of control resources interposed in several layers along the process which is subject to multiple risks. Keywords : Control plan, Risks monitoring, Inspection allocation, Capability, Capacity, Performances.
