Purpose: This paper mainly focuses on the exactly and precisely supply of carrying spare parts\udproblem which has a crucial impact on supporting work and improving the performance of\udequipment. Spare parts support has been the crux work that will be limited by allocation of\udspare parts and input support cost. Reasonable support strategy may subserve the high\udefficiency of available resources allocation and supporting the equipment in normal operational\udstatus. The purpose of this paper is to propose a dynamics model of spare parts support\udprocess based on considering the interaction of multiple factors, and explore the regulation of\uddynamics behavior in the system. Further, findings indicate that it is more helpful to achieve the\udoptimization strategy than to cut inventory, results of the former suggest that improve on the\udeffect of support so that will enhance the relevant support parameters of equipment.\udDesign/methodology/approach: Consider the feedback relationship among some important\udfactors of support that involves support cost, support time and maintenance ability. System\uddynamics theory is adopted to propose a dynamics model of spare parts support process, on\udthe analysis of multiple factors and casual relationship to find some major ones which have\udcrucial impact on spare parts support. Spare parts support cost and availability was regarded as\udthe control objective, moreover, adjust the control paramours and improve the effect of\udcannibalization and lateral supply scheduling strategy for spares support.\udFindings: The factors of spare parts supply, demand and maintenance have relationship of\udcontrol feedback, and adjust the value of some crucial factors can reduce the support cost and\udimprove the availability value. The main finding is that adopting cannibalization strategy under\udcondition of available materials can relieve the mission and operational availability decline\udcaused by shortage of spare parts. Combining the lateral supply and cannibalization strategy can\udreduce the inventory of warship carrying spare parts.\udPractical implications: By controlling the value of key factors regarding aspect of spare parts\udsupply, logistics and maintenance planning. Decision makers can have a visualization guideline\udto make the adjustment of support strategy, and can achieve better management of equipment\udand spare parts.\udOriginality/value: This paper proposes a dynamics model and focuses on exploring the\uddynamics behavior of the support system that could help in improving the ability of warship\udequipment to make supply support strategy easily. It can provide visualization guideline for\uddecision maker in the enterprise.
