Closed Loop Two-Echelon Repairable Item Systems
In this paper we consider closed loop two-echelon repairable item systems with repair facilities both at a number of local service centers (called bases) and at a central location (the depot). The goal of the system is to maintain a number of production facilities (one at each base) in optimal operational condition. Each production facility consists of a number of identical machines which may f...
متن کاملPeriodic Resource Reallocation in Multi-Echelon Repairable Item Inventory Systems
Given stock allocation in an inventory system, it is necessary to do reallocation periodically to address inventory imbalance and maximize availability. In this paper, we allow two opportunities to perform reallocation within a replenishment cycle. We derive a mathematical model to dynamically determine when to reallocate and how to reallocate. Experimental results show that multiplereallocatio...
متن کاملTwo-echelon Repairable Item Inventory System with Limited Repair Capacity under Nonstationary Demands
We study a repairable item inventory system under limited repair capacity and nonstationary Poisson demands, motivated by corrective maintenance of military equipment. Our goal is to minimize the cost of both spare and repair resource allocation. We propose an efficient analytical model that combines optimization modeling and queuing theory.
متن کاملModeling Multi-Echelon Multi-Supplier Repairable Inventory Systems with Backorders
This paper considers an inventory system responsible for repairable equipments located at several operational sites, each in different area. When a failure occurs at the operational site, spare parts are required. We analyze a multiple-supplier inventory system that includes an internal repair shop that offers several modes of repair with different repair times and an external supplier of spare...
متن کاملInterval Availability Analysis of a Two-echelon, Multi-item System
In this paper we analyze the interval availability of a two-echelon, multi-item spare part inventory system. We consider a scenario inspired by a situation that we encountered at Thales Netherlands, a manufacturer of naval sensors and naval command and control systems. Modeling the complete system as a Markov chain we analyze the interval availability. We compute in closed and exact form the ex...
