Available in PDF, EPUB and Kindle. Book excerpt: The United States is moving into a new era in which the enemy no longer provides symmetric opposition. The Navy and Marine Corps will face new challenges in the way they deploy and conduct future operations. One important way in which these challenges will be met involves sea-based operations, which provide the sustainment necessary for prolonged operations and prevent unwanted operational pauses. Recent combat operations in Operation Iraqi Freedom (OIF) demonstrated difficulties when sustaining forces from logistics bases ashore. For example, advancing the Army and Marines to Baghdad in OIF consumed large amounts of fuel and ammunition. The resupply could not replenish supplies and an operational pause began on 29 March, 2003. To prevent operational pauses, rapid movement from the sea to the objective must be implemented. This thesis analyzes the problem of finding an optimal mix of Combat Logistics Force shuttle ships required to sustain the sea base. This is accomplished through two optimization models. The first one determines a shuttle mix that guarantees minimum inventory levels at the sea base at all times. Since this requirement may cause some shuttles to be partially loaded, the second model manually assigns the shuttle mix and then minimizes unmet demand. This model yields a mix of shuttles that strikes a balance between shuttle cost and meeting sea-base demand. The analysis in this thesis involves three Marine Corps Combat Development Command (MCCDC) scenarios. The scenarios differ by distances from the closest ALSS to the sea-base. Each scenario emulates a small-scale contingency war and the supported war is tailored to a 2015 Marine Expeditionary Brigade. The operation lasts 45 days in all tested scenarios. The commodities dealt with in these scenarios are fuel, provisions, and ordnance. Demand is initially consumed at a 5-day surge rate and the remaining 40 days of the operation are consumed at a sustain rate. (7 tables, 10 figures, 20 refs.).

Available in PDF, EPUB and Kindle. Book excerpt: At the request of the Chief of Naval Operations, the National Research Council (NRC) conducted a study to determine the technological requirements, operational changes, and combat service support structure necessary to land and support forces ashore under the newly evolving Navy and Marine Corps doctrine. The Committee on Naval Expeditionary Logistics, operating under the auspices of the NRC's Naval Studies Board, was appointed to (1) evaluate the packaging, sealift, and distribution network and identify critical nodes and operations that affect timely insertion of fuels, ammunition, water, medical supplies, food, vehicles, and maintenance parts and tool blocks; (2) determine specific changes required to relieve these critical nodes and support forces ashore, from assault through follow-on echelonment; and (3) present implementable changes to existing support systems, and suggest the development of innovative new systems and technologies to land and sustain dispersed units from the shoreline to 200 miles inland. In the course of its study, the committee soon learned that development of OMFTS is not yet at a stage to allow, directly, detailed answers to many of these questions. As a result, the committee addressed the questions in terms of the major logistics functions of force deployment, force sustainment, and force medical support, and the fundamental logistics issues related to each of these functions.

Download or read book Optimization of a Marine Corps Artillery Battalion Supply Distribution Network written by and published by . This book was released on 2007 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: Currently, the Marine Corps does not have a process or system to distribute supplies in support of combat operations in an optimal manner. We consider the problem of re-supplying a forward-deployed United States Marine Corps artillery battalion. Specifically, we model a supply distribution network of roads between the battalion supply area, the firing batteries, and the headquarters battery. Our objective is to develop a decision support tool to help a logistics officer build efficient supply convoys that deliver all demanded supplies to the requesting units in the shortest convoy route. The supply distribution network consists of a set of locations connected by roads of known length. A small number of these nodes are logistics nodes that either supply or demand the commodities in our model, while the majority of the nodes are transshipment nodes. We use Dijkstra's algorithm to calculate the associated shortest travel distance between each pair of logistics nodes and then enumerate all possible tours through the logistics nodes. From this list of potential convoy routes, we determine the best combination of vehicles and supplies to assign to each in a manner that satisfies operational constraints and meets the mission objectives. The decision the logistics officer has to make is to determine the convoy(s) that will deliver the demanded supplies in the shortest convoy route with the number of available vehicles to support the convoy. This model provides insight to the logistics officer about how to build convoys to distribute supplies optimally within the network.

Download or read book Sea Based Logistics Full Speed Ahead written by Joseph Haviland and published by . This book was released on 1999 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reduced access to and availability of forward-based military installations can impede the operational commander's reach in projecting combat power and constrain his logistics effort. Emerging concepts have been proposed that mitigate infrastructure reduction without sacrificing support to the fluid nature of logistics. Sea Based Logistics (SBL) is the conceptual centerpiece of how the United States Marine Corps (USMC) envisions logistics support and sustainment for the next century. This research project enthusiastically advocates SBL. After defining SBL and presenting the thesis, the paper begins with a brief historical perspective of sea basing and SBL. A summation of adopted business practices and developments in modern logistics as they pertain to SBL follows. The importance of sealift and current SBL capabilities provides a point of departure for SBL's future. Emphasis is placed on what present-day naval expeditionary forces can do to further exploit and encapsulate the fusion of SBL. The author's principal focus includes an analysis of what SBL offers the operational commander. The brief scope of this effort leaves opportunities for others to argue the many unresolved and difficult SBL issues. SBL provides the operational commander the means to further extend his operational reach through the integration of business practices, emerging technologies, and the use of available sealift platforms. With continued refinement and increased sophistication of SBL platforms, naval expeditionary forces will continue to provide the operational commander an added dimension and enhanced force multiplier. SBL provides the operational commander with the synchronization of the right forces, material, and support, in the right quantity, at the right place and right time.

Available in PDF, EPUB and Kindle. Book excerpt: New warfare doctrine for the U.S. Marine Corps emphasizes small, highly mobile forces supported from the sea, rather than from large, land based supply points. The goal of logistics planners is to support these forces with as little inventory on land as possible. We show how to configure the land based distribution system over time to support a given battle plan with minimum inventory. Logistics planners could use the model to support tactical or operational decision making.

Download or read book Analysis of the Seaborne Mobile Logistic System SMLS Maintenance Subsystem Using the the Maintenance Optimization Model Version II written by Michael Gray and published by . This book was released on 1975 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Seaborne Mobile Logistic System (SMLS) defines operational procedures and allocation of resources for the logistic support of a Marine Corps Landing Force ashore from a seabase afloat. In evaluating the SMLS approach, ground maintenance of Marine Corps end items of an Amphibious Task Unit/Marine Amphibious Unit (ATU/MAU) and an Amphibious Task Group/Marine Amphibious Brigade (ATG/MAB) is considered independently because of its effects on requirements for amphibious shipping and large resources. A computer simulation model of the maintenance system was developed to demonstrate the feasibility of, and to determine the requirements for, performing maintenance under SMLS. A user's guide to the model has been documented separately.

Book excerpt: ' ... From the Sea', the Navy and Marine Corps vision statement published in 1992, is examined from an operational logistics perspective. The four conditions that will shape the context of logistics challenges are increased demand for use of naval expeditionary forces, defense cutbacks, fewer forward logistics bases and the need to support multiple geographic CINCs or JTFs. To evaluate the goals of operational logistics two effectiveness measures are developed. Responsiveness measures whether logistics can support a wide range and scope of operations. REACH measures the where, when and duration of sustainment. Seven logistics imperatives are proposed to focus attention on vital command and staff planning matters. The fusion of intelligence, CINC staff and liaison team logistic data must form the planning basis. The precise tailoring of embarked assets will ensure the relevance of self-contained forces. Two additional imperatives stress the need for new forward bases and power projection infrastructure. Realistic training must occur to guarantee confidence between combat and logistic forces and to isolate shortfalls. The professional development of operational logistics leaders and planners must continue and, finally, seamless staff integration between naval expeditionary and CINC joint staffs is vital to best exploit the joint use of scarce logistics resources.

Download or read book Integrated Logistics Optimizing the USMC Quadrant Model Using Intelligent Agent Technologies written by and published by . This book was released on 2002 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1998, the Marine Corps initiated the Integrated Logistics Capability (ILC) to specifically address issues related to Marine Corps logistics doctrine, policy, and processes. The purposes of ILC initiatives were to define, measure, and improve core logistics capabilities to meet the challenges of the new millennium and beyond. During a four week Best Business Practices seminar hosted by Penn State, several key concepts were analyzed that would improve cost leverage, enhance the robustness of supplier relationships, and substitute technology and information for inventory. In an effort to successfully integrate these issues, a segmentation methodology or Quadrant Model approach was introduced. The Quadrant Model is essentially a two-by-two matrix that classifies products, services, and inventory items into four mayor cells. Each cell is further categorized by uniqueness and valve, and each cell implies different approaches to managing inventory, supply chains, and vendor relationships. The objective of this thesis is to determine how Intelligent Agent (IA) technologies may innovate the logistical processes associated the critical quadrant, which categorizes materials, products and services that are unique, high valve in terms of cost, and therefore high risk. These materials may only be available from a few sources, are in limited quantities, and require extensive coordination and sharing of information between parties. The researcher applies a model derived from previous thesis work that examined the application of IA technology as a method to innovate the Standard Procurement System (SPS). Using a high-level process model of the 'critical' quadrant, the researcher identifies two applications of IA technology that may support attributes within the 'critical' quadrant.

Available in PDF, EPUB and Kindle. Book excerpt: The Navy has to choose the number of, and designs for, ships in the Combat Logistics Force (CLF), and then plan how to use them to provide logistical support to our Carrier Strike Groups, Expeditionary Strike Groups, and Seabasing platforms engaged in any variety of worldwide conflicts. CLF ships are very expensive to build and equip and our budget is limited we need to make sure the ships we buy and the way we integrate these with our CLF fleet can continue to provide the flexible support our Navy requires. We introduce a decision support tool using a global sea route and resupply base model, and a daily time resolution optimization of CLF ship activities to support any complete, worldwide scenario. Our result is an optimal, face-valid daily operational logistics plan a schedule of evolutions for each available CLF ship. We discover exactly how to use CLF ships to support a notional, but particularly relevant, preemptive combat scenario with follow-on humanitarian assistance missions. Finally, we study how changing CLF ship numbers and missions can enhance operational effectiveness.

Book excerpt: There can be only one logistics infrastructure to provide attainable flexible and responsive sustainment in support of operational movement and maneuver. While warfighting needs set logistics requirements, the logistics capabilities available for Operational Maneuver from the Sea will, if left unrevised, limit warfighting potential and the courses of action available to field commanders. The Navy and Marine Corps should create an integrated Operational Maneuver from the Sea logistics concept that supports the concept of operations at each stage in the sustainment process.

Download or read book Sea Based Logistics Does It Satisfy the Operational Commander s Need written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Naval logistics leaders of today have proposed sea-based logistics as the operational concept for supporting the future commanders in the battlespace environment. This concept eliminates the traditional need for Ground Combat Support Service (GCSS) element and bases all logistical operations at sea. This new concept espouses the same precepts as put forth in JV2010 within its focused logistics premise. For this concept to work as stated, the Navy must work together with the other services to eliminate the current stovepipe logistics support doctrine of today. Even with modifying current logistics doctrine, there are several conditions that make the 100% conversion to sea-based logistics impracticable. The current limitations of technology in throughput capability, lack of defense against asymmetric threats, and the inability to provide flexible maneuver options for the joint commander questions whether this concept is the ultimate solution. In light of past history and the uncertain nature of future warfare, the United States Naval Service must not abandon its GCSS capabilities. Instead, the ability to use GCSS elements along with sea-based logistics will provide the Joint Commander the flexibility to counter the full spectrum of conflict from military operations other war to war.

Download or read book Optimization of Logistics and Supply Chain Systems written by Turkay Yildiz and published by . This book was released on 2016-12-07 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the collection of my own studies in the optimization of logistics and supply chain systems, targeted to a broad readership. In this book, first few chapters of the optimization concepts come out of the materials I used to refer while doing my research. I brought together some of these materials to form a guidance material on the fundamentals of the optimization concepts along with my own studies in the application of optimization methods. For a macro level logistics and supply chain systems optimization perspective, I added several chapters that are the results of my studies, which use the Global Trade Analysis Project (GTAP and GDyn) simulations. The static and dynamic computable general equilibrium (CGE) concept is also the essential part of the optimization study of logistics and supply chain systems. Therefore, the fundamentals of the static and dynamic (CGE) models are introduced. As the demand for logistics depends mostly on the volume of trade and trade patterns, international trade affects the transport and logistics, as it might generate a higher or lower demand for transport and logistics services, which are calculated by various approaches of optimization studies. This book consists of six parts and twenty chapters. The first part of the book, which includes three chapters, is about introduction to optimization with typical base problems and algorithms for solving these problems. The second part of this book includes five my own researches in the application of optimization methods. The third part of the book shortly introduces you to the general concepts of the computable general equilibrium models (CGE) and presents you the fundamentals of a CGE model. In each chapter of the fourth part, short articles that include five simulations based on various scenarios are presented. The fifth part of the book briefly introduces you to the basic concepts of the computable general equilibrium models (CGE) and then, presents you the fundamentals of dynamic general equilibrium models. In each chapter of the sixth part, two short articles that simulate various scenarios are presented. All the chapters in this book are independent of each other. I hope you will find this book informative, beneficial and appropriate for your needs. Turkay Yildiz, M.A., Ph.D.
