Simulation of dynamics behaviors for shipping equipment support with system dynamics analysis approach
Abstract: The exactly and
precisely supply of carrying spare parts has a crucial impact on support and
could improve the performance of equipment. Spare parts support is the crux
work which will be limited by spare parts allocation and support cost input.
Reasonable support strategy can help in making good use of available resources
and support the equipment in normal operational status. The purpose of this
paper is to propose a dynamics model of spare parts support process based on
considering the interaction of multiple factors, and explores the regulation of
dynamics behavior in the system. In order to achieve the optimization strategy
to improve the effect of support so that will enhance the relevant support
parameters of equipment.
Design/methodology/approach: Meditate the feedback relationship among
some important factors of support that involve support cost, support time and
maintenance ability. System dynamics theory is adopted to propose a dynamics
model of spare parts support process, on the analysis of multiple factors and
casual relationship to find some major ones which have crucial impact on spare
parts support. Spare parts support cost and availability was regarded as the
control objective, moreover, adjust the control paramours and improve the
effect of cannibalization and lateral supply scheduling strategy for spares
support.
Findings: The factors of spare parts supply, demand and maintenance have
relationship of control feedback, and adjust the value of some crucial factors
can reduce the support cost and improve the availability value. The main
finding is that adopting cannibalization strategy under condition of available
materials can relieve the mission and operational availability decline caused
by shortage of spare parts. Combining the lateral supply and cannibalization
strategy can reduce the inventory of warship carrying spare parts.
Practical implications: By controlling the value of key factors regarding
aspect of spare parts supply, logistics and maintenance planning. Decision
makers can have a visualization guideline to make the adjustment of support
strategy, and can achieve better management of equipment and spare parts.
Originality/value: This paper proposes a dynamics model and focuses on
exploring the dynamics behavior of the support system that could help in
improving the ability of warship equipment to make supply support strategy
easily. It can provide visualization guideline for decision maker in the
enterprise.
