Posturing Spares for Great Power Competition

NPS NRP Executive SummaryEffectively posturing spares is essential to support forces for Great Power Competition. The purpose of this project is to study the effectiveness of spare posturing strategies towards the improvement of operational availability. Possible strategies for positioning of spare parts include inventory augment and sparing models such as readiness-based sparing (RBS) and demand-based sparing (DBS). An alternative strategy is the use of a depot ship with repair and production capabilities through a combination of subtractive manufacturing and additive manufacturing (AM). The different strategies will be simulated to identify their effect on operational availability and operating cost to improve the readiness of the warfighter.N4 - Fleet Readiness & LogisticsThis research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE 0605853N/2098). https://nps.edu/nrpChief of Naval Operations (CNO)Approved for public release.

Navy Expeditionary Readiness Cost Modeling

NPS NRP Project PosterOPNAV N834 (Expeditionary Readiness) presently uses an N81 accredited Capability Costing Model (CCM) to inform the annual sustainment requirements for the Navy Expeditionary Combat Enterprise (NECE). The CCM is dated, limited in capability, and lacks adaptability for incorporating measures such as readiness. The lack of a readiness cost model limits proper programmatic assessments on force readiness issues, including costs of readiness achieved and impacts to readiness based on "what-if" drills. The objective of this research is to analyze execution data, phases of Optimized Fleet Response Plan (OFRP), readiness, and other relevant unit and OFRP phase data to identify the cost drivers of the annual sustainment requirements of NECE. We will dissect the existing CCM, assess the importance of factors in accurately predicting sustainment spending, and explore avenues for model enhancement.N8 - Integration of Capabilities & ResourcesThis research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE 0605853N/2098). https://nps.edu/nrpChief of Naval Operations (CNO)Approved for public release.

Theater Torpedo Inventory Optimization

NPS NRP Executive SummaryAnti-submarine warfare (ASW) is a core mission area for the U.S. Navy and an essential component in achieving sea control. The allocation of torpedoes in support of ASW across a U.S. Fleet is currently a manual process based on shore-based personnel's experience or historical norms. This study will analyze the impact of torpedo loadouts incorporating a complex set of constraints ranging from platform capabilities to probability of kill. A mixed-integer program will be used to compare the effectiveness of different torpedo loadouts. The goal of this work is to maximize the probability of a successful outcome in a theoretical campaign against anticipated submarine threats.N8 - Integration of Capabilities & ResourcesThis research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE 0605853N/2098). https://nps.edu/nrpChief of Naval Operations (CNO)Approved for public release.

Naval Logistic Network for The Great Power Competition and Operation in Contested Environment

NPS NRP Project PosterThis research will look at the current naval logistical concept to determine possible avenues to strengthen the current force, to sustain the logistics operations and to prepare it for a contested and degraded environment. We will investigate how degraded communication could affect the current coordination capabilities of the supply chain and its ability to support our forces in phase 0-2. The uncertainty surrounding the industrial ability to adapt to new demand signals and to the lack of real time demand signals will be investigated. Lastly, we will seek to find new concepts and technology that can be used to mitigate cyber-attacks and subsequent degradation of the communication network that support the supply chain. This research builds on the researchers' current and recent research into in-theater repair, phase II sustainment, HSP in contested environment, fuel logistics, and OPSEC consideration in overseas operations.N4 - Fleet Readiness & LogisticsThis research is supported by funding from the Naval Postgraduate School, Naval Research Program (PE 0605853N/2098). https://nps.edu/nrpChief of Naval Operations (CNO)Approved for public release.
