Production Planning and Opportunistic Preventive Maintenance for Unreliable One-Machine Two-Products Manufacturing Systems
نویسنده
چکیده
This paper develops an effective joint production, setup and maintenance control policies in an unreliable one-machine two-products manufacturing system. The main objective is to reach a higher synchronization level of the preventive maintenance (PM) interventions in the planning of production activities. The proposed joint control policy integrates the concept of the opportunistic maintenance by taking advantage of the machine stoppage during setup operations in order to conduct preventive actions. This aims to increase the machine availability and to reduce the risk of shortages. Performance evaluation of the proposed control policy is carried out using a combined continuous/discrete event simulation model. It is subsequently analyzed by statistical techniques of optimization such as design of experiments, analysis of variance and response surface methodology. An illustrative numerical example followed by an in-depth comparison study for a wide range of the system configurations are performed in order to demonstrate the usefulness and the robustness of the results.

Adaptive policy of buffer allocation and preventive maintenance actions in unreliable production lines
The buffer allocation problem is an NP-hard combinatorial optimization problem, and it is an important design problem in manufacturing systems. The research proposed in this paper concerns a product line consisting of n unreliable machines with n − 1 buffers and a preventive maintenance policy. The focus of the research is to obtain a better trade-off between the buffer level ...
متن کاملAn integrated production and preventive maintenance planning model with imperfect maintenance in multi-state system
Production planning and maintenance are two important problems in manufacturing systems. Despite the relationship exists between these two problems due to sudden failures and production capacity occupied by maintenance activities, each of these problems planned separately and as a result program and model efficiencies reduce in the real world. The aim of integrated production and maintena...
متن کاملPeriodic flexible maintenance planning in a single-machine production environment
Preventive maintenance is the essential part of many maintenance plans. From the production point of view, the flexibility of the maintenance intervals enhances the manufacturing efficiency. On the contrary, the maintenance departments tend to know the timing of the long term maintenance plans as certain as possible. In a single-machine production environment, this paper proposes a simulation–o...

Most of the inventory control models assume that quality defect never happens, which means production process is perfect. However, in real manufacturing processes, the production process starts its operation in the in-control state; but after a period of time, shifts to the out-of-control state because of occurrence of some disturbances. In this paper, in order to approach the model to real man...

In today's competitive market, quality has an important role in manufacturing system. The manufacturers attempt to maintain their production system in a proper condition to produce high quality products. One of the key factors to achieve this goal is maintenance policy. Most studies on maintenance focused on machines and less attention has been paid to human resources as the most important fact...
