An Optimal Production Planning and Maintenance Policy for a Multiple-Product and Single Machine under Failure Rate Dependency

چکیده
This paper addresses the production and maintenance problem of multiple-product manufacturing system satisfying several random demands corresponding to every product. The goal of this study is to establish an economical production planning followed by an optimal maintenance strategy, taking into account the influence of the multiple-product production rate on the materiel degradation. Analytical models are developed in order to minimize sequentially the production/holding costs and the total maintenance cost. A numerical example is presented to prove the developed approach.

Optimization of single outsourcer–single subcontractor outsourcing relationship under reliability and maintenance constraints
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...
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...
متن کاملJoint optimization approach of maintenance planning and production Scheduling for a multiple-product manufacturing system
In this paper, we deal with the problem of maintenance planning and production planning for a multiple-product manufacturing system. The manufacturing system under consideration consists of one machine which is subject to random failures and produces several products in order to satisfy some random demands. At any given time, the machine can only produce one type of product. The purpose of this...
متن کاملIntegrated Inspection Planning and Preventive Maintenance for a Markov Deteriorating System Under Scenario-based Demand Uncertainty
In this paper, a single-product, single-machine system under Markovian deterioration of machine condition and demand uncertainty is studied. The objective is to find the optimal intervals for inspection and preventive maintenance activities in a condition-based maintenance planning with discrete monitoring framework. At first, a stochastic dynamic programming model whose state variable is the ...
متن کاملA forecasting system by considering product reliability, POQ policy, and periodic demand
This paper presents an economic production quantity (EPQ) model with a periodic order quantity (POQ) policy, product reliability and periodic demand. The machine reliability has decreased over time; therefore, the rates of perfect and defective products reduce and increase over time, respectively. A fixed percentage of these products are reworked while the rest is wasted. Some equipment in thei...
