Improving the US Army's Furnishing Management Process using the Lean Six Sigma methodology

Trujillo, Allen Matthew 11 December 2013 (has links)
This report describes the major steps used in the Army’s LSS methodology, provides a brief overview of the Unaccompanied Personnel Housing and the Army Family Housing and briefly describes some of the initial steps intended to start improving the process. In the improvement phase, two detailed models (The EOQ Model and the Hadley and Whitin (Q,r) Model) used for inventory management are discussed. This report also provides a series of recommendations that include suggestions for baseline inventory levels, some ideas for future data collection, example improvements to some data input sheets as well as a few tasks for UPH and AFH managers to reduce cost and improve the overall efficiency of the system. / text

Blažej, M. Stock management in corporation. Diploma thesis. Brno: Mendel University, 2019. This thesis is focused on the optimization of the process of purchasing stocks for a selected section of a manufacturing company. After analyzing the inventory management process and ABC analysis, the economically advantageous order quantity of the stock items is calculated. According to these calculations, a suggestion for an economically advantageous order size for stock items is presented. The benefits are proven by the impact on total costs of holding and ordering. Also, a suggestion for saving storage space in selected section´s warehouse is presented.

Optimizing within the Supply Chain: A Mathematical Model for Inventory Optimization with respect to Demand Planning / Optimering inom värdekedjan: En matematisk modell för lageroptimering med avseende på efterfrågeplanering

Bork, William, Giedraitis, Martynas January 2023 (has links)
This thesis examines how to design a mathematical inventory model for a ”Fast Moving Consumer Goods”-company (FMCG-company), which determines the optimal reorder point and order quantity such that the average inventory cost is minimized. The thesis was made in collaboration with a ”Software as a Service”- company which provided the data containing information about the products and inventory management of one of their customers, a FMCG-company. The thesis first considers a basic EOQ-model, with constant demand rate, that suggests a reorder time and order quantity for the products. Since constant demand rate might be an unrealistic assumption for a FMCG-company, the thesis also considers a (R,Q)-model, where the demand was based on a forecast made by using the Holt-Winters model on previous sales history. The solutions were found by investigating the singular points and comparing them to the critical point. The thesis shows that the EOQ-model gives useful results for the most indemand products, while the reorder times for the less popular products are instead impractically high. The (R,Q)-model showed more stable solutions for all products and therefore proves to be a better inventory model for FMCG-companies, as expected. Simulations of the (R,Q)-model showed various inventory cases, where some showed a mismatch between the inventory level and the demand. The cases shows how demand planning can be applied for different products for when to consider changing inventory strategy or discontinuing products and how the orders can be made optimally. / Detta examensarbete undersöker hur en matematisk lagermodell kan utformas för ett ”Fast Moving Consumer Goods”-företag (FMCG-företag), som bestämmer den optimala beställningspunkten och orderkvantiteten så att den genomsnittliga lagerkostnaden minimeras. Examensarbetet gjordes i samarbete med ett ”Software as a Service”-företag som tillhandahöll data innehållandes information om produkter och lagerhantering hos en av deras kunder, ett FMCG-företag. Avhandlingen behandlar först en grundläggande EOQ-modell, med konstant efterfrågan, som föreslår en återbeställningstid och orderkvantitet för produkterna. Eftersom att en konstant efterfågan kan anses vara ett orealistiskt antagande för ett FMCG-företag, tar avhandlingen även upp en (R,Q)-modell, där efterfrågan baserades på en prognos gjord med hjälp av Holt-Winters-modellen på tidigare försäljningshistorik. Lösningarna hittades genom att undersöka de singulära punkterna och jämföra dem med den kritiska punkten. Avhandlingen visar att EOQ-modellen ger användbara resultat för de mest efterfrågade produkterna medan beställningstiderna för de mindre populära produkter är ofta opraktiskt höga. (R,Q)-modellen visade mer stabila lösningar för alla produkter och visar sig därmed vara en bättre lagermodell för FMCGföretag, som förväntat. Simuleringar av (R,Q)-modellen visade olika fall, där vissa visade en obalans mellan lagernivån och efterfrågan. De olika fallen visar hur efterfrågeplanering kan tillämpas för olika produkter för när man ska överväga att ändra lagerstrategi eller avveckla produkter och hur beställningarna kan göras optimalt
