Spare Parts Transportation Optimization Considering Supportability Based on Uncertainty Theory

چکیده
Ensuring a consistent, continuous, and efficient spare parts supply is critical issue that must be addressed in the equipment support system. In order to effectively improve coverage level handle common asymmetry information present practical applications, transport vehicle routing scheduling model was further optimized. We integrated supportability requirements uncertainty theory into better describe actual uncertain demand of each site. selected three indicators as constraints, redefined them with variables, then completed chance-constrained on this basis. Once confidence specified, constraints can transformed deterministic finally, equivalent solved easily. addition, feasible solution found through genetic algorithm, numerical example provided validate model’s rationality. The proposed method successfully seeks balance between total cost supportability.

On spare parts optimization
In the book “Optimal inventory modeling of systems: multi-echelon techniques” the author Craig Sherbrooke, who has developed several important model in this area, describes a part of the model cosidered in this manuscript as follows (in “aircraft language”): “When a malfunction is diagnosed on an aircraft, the malfuncioning item is removed from the aircraft and brought into base supply. If a sp...
متن کاملCondition based spare parts supply
We consider a spare parts stock point that serves an installed base of machines. Each machine contains the same critical component, whose degradation behavior is described by a Markov process. We consider condition based spare parts supply, and show that an optimal, condition based inventory policy is 20% more efficient on average than a standard, state-independent base stock policy. We further...
متن کاملInventory-transportation integrated optimization for maintenance spare parts of high-speed trains
This paper presents a 0-1 programming model aimed at obtaining the optimal inventory policy and transportation mode for maintenance spare parts of high-speed trains. To obtain the model parameters for occasionally-replaced spare parts, a demand estimation method based on the maintenance strategies of China's high-speed railway system is proposed. In addition, we analyse the shortage time using ...
متن کاملEfficient aircraft spare parts inventory management under demand uncertainty
In airline industries, the aircraft maintenance cost takes up about 13% of the total operating cost. It can be reduced by a good planning. Spare parts inventories exist to serve the maintenance planning. Compared with commonly used reorder point system (ROP) and forecasting methods which only consider historical data, this paper presents two non-linear programming models which predict impending...
متن کاملResearch on Equipment and Spare Parts Management Based on Theory of Constraints
On the basis of analyzing the relationship between the equipment system and spare parts inventory, this paper proposes two-level equipment and spare parts system management based on the Theory of Constraints. From the system point of view and according to the Theory of Constraints, the manufacturing organization identifies bottleneck equipments in equipment system and makes the bottleneck equip...
