Integrated maintenance policy for transportation system according to a supply chain
Abstract
Competition between firms and government incentives is driving researchers to look for optimal ways and strategies to ensure the optimal running of their systems, taking into account various constraints, sometimes conflicting, like economical, operational and environmental. The aim of workout study consists in developing an optimal maintenance policy of the transportation system in a supply chain. The transported product may be considered as a perishable product that must be supplied to the consignee within the agreed time. In this context, the means of transport must be available for distribution missions. Indeed, synchronization between the availability of transport means and maintenance becomes compulsory, in order to realize on economic success and attract with reducing operation costs. The task is to satisfy the demand over time with high service level, based on the maintenance strategy while respecting the fixed environmental constraints. It is easy to see that the simultaneous considering of these economical and operational goals induce the improvement of a logistics chain. In the proposed study a survey targeting two types of transportation systems is conducted according to logistic services and the maintenance plan conforming to every proposed type. Then we investigated the used tools in order to build an objective function integrating system reliability and high logistic service.
