Production/maintenance Policies Optimization with Linear Degradation in a Subcontracting and Withdrawal Constraints
نویسنده
چکیده
In this paper, we deal with the problem of joint maintenance and production under a subcontracting and withdrawal right constraints. The manufacturing system consists of a machine M that produces a single product in order to satisfy a random demand under given service level constraint. We first establish an optimal production plan which minimizes the total inventory and production cost taking into consideration the subcontractor and the withdrawal right constraints. Secondly, using this optimal production plan we derive an optimal maintenance plan which minimizes the total maintenance cost and takes into account the influence of production rates on the machine degradation. Finally, a numerical example is studied in order to apply the developed approach.

متن کاملDevelopment of joint maintenance and production strategies in a subcontracting environment
This article, inspired by an industrial problem, develops efficient maintenance and just-in-time production policies in a subcontracting environment according to two orientations. The first invokes subcontracting with the objective of satisfying a constant customer demand knowing that our production system, composed of a machine M1, cannot satisfy the totality of demand. Subcontracting is repre...

In this paper, we focus on outsourcing activities optimization problem in single period setting. In some situations, capacity planning or outsourcing is a one-time event and can be modeled as a single period problem. The aim of this research is to balance the trade-off between two echelons of a supply chain consisting of a single outsourcer and a single subcontractor. Each part is composed of a...

A constraint is a limitation or a restriction that poses a threat to the performance and efficiency of a system. This paper presented a tactical review approach to production constraints modeling. It discussed the theory of constraints (TOC) as a thinking process and continuous improvement strategy to curtail constraints in other to constantly increase the performance and efficiency of a system...
متن کاملAn economic-statistical model for production and maintenance planning under adaptive non-central chi-square control chart
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...
