Full textThis research project proposes a supply management model in a consumer goods company in Lima, Peru, to improve stock control and avoid raw materials stockouts and overstock. A Kraljic matrix was used to identify products based on their criticality considering material segmentation, warehouse capacity and times, and ABC segmentation to classify products on each quadrant of the matrix. This project also focuses on defining purchasing and supply strategies in each quadrant of the matrix. This model involves the development of three processes that are related to a new purchasing strategy: economic order quantity, lot-for-lot ordering, and just in time. This new system is based on a more accurate inventory because continuous improvement attracts employees’ attention and engages them in reducing the number of manual notifications made by operators every month. Moreover, after implementing the new procedure for recording inventories, the inventory record was 87% accurate, whereas, in the past, the inventory was not counted and was performed by employees of other areas.

This thesis addresses the challenges of improving the on-time delivery performance of a high-volume critical part type in a high-product-mix manufacturing facility of valves. Preliminary analysis on the push-type production system of the valve manufacturing cell shows that long production lead time caused by excessive inventory queuing and accumulation as well as lack of standardized finished goods inventory management policy are the major factors that limit the on-time delivery performance. A new pull-type production system is developed with the design of a highly responsive fabrication line which enables faster material movement and an efficient inventory review framework for real-time monitoring of inventory positions. A dedicated production line with the placement of effectively controlled Work-In-Process (WIP) buffers is constructed, which is capable of reducing the production lead time by more than 80%, along with a 40% reduction in overall WIP volume. Moreover, a finished goods inventory review policy is proposed based on the (s, S) policy which significantly eliminates the possibilities of backlog and inventory explosion by the setup of both lower and upper control limits on inventory positions. The suggested policy is expected to ensure a service level of at least 95% during peak demand period, with up to 50% potential reduction in average inventory level held by the system. A Kanban system is also established to coordinate operations in the proposed pull-type production system.

The mission of the Always Available retail replenishment business at NIKE is to ensure consumer-essential products are in-stock at retailers at all times. To achieve this goal, NIKE has developed a forecast-driven, make-to-stock supply chain model which allows retailers to place weekly orders to an on-hand inventory position in a distribution center. The challenge facing the business is how to design an inventory strategy that achieves a high level of service to its customers while minimizing inventory holding cost. Specifically, safety stock holding cost is targeted as it accounts for the majority of on-hand inventory and can be reduced without significantly impacting the underlying supply chain architecture. This thesis outlines the application of multi-echelon inventory optimization in a retail replenishment business model. This technique is used to determine where and how much safety stock should be staged throughout the supply chain in order to minimize safety stock holding cost for a fixed service level. Provided a static supply chain network, the ideal safety stock locations and quantities which result in minimal total safety stock holding cost is determined. For this business, the optimal solution is to stage lower-cost component materials with long supplier lead times and high commonality across multiple finished goods at the manufacturer in addition to finished goods at the distribution centers. Safety stock holding cost reduction from component staging increases significantly when the distance between manufacturers and the distribution center decreases and for those factories producing a variety of finished goods made from the same component materials due to inventory pooling. Forecast accuracy drives the quantity of safety stock in the network. The removal of low volume, highly unpredictable products from the portfolio yields significant inventory holding cost savings without a detrimental impact to revenue. By deploying the optimal safety stock staging solution and by removing unpredictable products, this analysis shows that finish goods safety stock inventory would be reduced by 35% for the modeling period (calendar year 2012) while only decreasing topline revenue by 5%.

While festivals bring a reason to cheer for everyone, businesses dealing with a spike in demand for perishables may have to live with the misery of lost sales and/or expired items. In the case of the dairy industry that deals with liquid milk, both raw material, and finished goods are perishable, which implies that merely stockpiling inventory of either item, without paying attention to potential inventory losses, cannot be an optimal strategy. In developing countries, the supplier base for perishables like milk, fruits, vegetables, flowers, etc. mostly comprise of small farmers instead of corporate/professional agencies, thus leading to supply variability. During special occasions like festivals, as individuals set aside more of the raw material for their own consumption, we encounter a reduction in supply. Around the same time, we notice a spike in customer demand, leading to a demand-supply mismatch. Companies dealing with perishables need an analytical approach to manage this.
In this thesis, we present a framework to address this problem of intermittent demand-supply mismatch using a 3-stage stochastic optimization model. We decide on the sourcing targets, the production plans based on supply realized, and finally, the dispatch plan based on orders received. As a case study, we analyze the operations and data from a private dairy company in eastern India, to understand the research problem and the applicability of the resulting model. We notice the impact of demand spikes and supply reduction in two areas: we increase supply targets in the periods preceding the demand spike; and we increase supply targets in periods when supply is expected to decrease, while demand is as usual. When there are multiple festival days within the time series, the compounding of impact depends on the sequencing of the events.
Finally, when we introduce the realistic constraint that the supply target needs to be constant throughout the time series, we see a degradation in the profitability, as we need to tradeoff between lost sales and wasted products. While the focus of this case study is the dairy industry, the conclusions from this research are broadly applicable to other industries dealing with perishables.

Full textIn general, lean strategies in the textile sector are applied in production to improve productivity, reduce production time, and reduce errors, among other aspects. However, there are also documented studies, which are not common in the literature that uses these strategies to improve storage operations. This study shows the implementation of the Lean 5S Hybrid tool in the warehouse of a textile company based in Lima. The objective of the implementation was to improve productivity in the warehouse, as there were high response times when searching for materials, which reduced production time, warehouse redistribution, better using available space, and being able to strategically locate main materials. The results revealed an increase in warehouse productivity 3.95 times the initial one, an Inventory Record Accuracy of 98.17%, a decrease in the requirement search time by 66.12% (from 25 to 8 min), and stock rotation of 6.22 times.

Currently, demand and inventory planners at NIKE Always Available (NIKE's replenishment business) experience difficulty in managing long-lifecycle highly-seasonal products like soccer equipment and fleece apparel. Very often items are either stocked out at retailers or piling up at Distribution Centers (DCs). NIKE manages inventory to a 95% item fill rate for all replenishment products. Highly seasonal products generally have unpredictable demand patterns which lead to either stock outs or excess inventory. These imbalances in inventory occur without fully understanding the cost and benefit of holding the inventory. To understand the cost and benefit of holding inventory for long lifecycle highly seasonal products, the author analyzed the current profitability, revenue, service level, and inventory position of soccer equipment, sandals, and fleece apparel. From these results, the author modeled the benefits to the above metrics of managing inventory via a dynamic service level approach that varies the service level over the season. Next, the author modeled the benefits of managing inventory via dual-sourcing. Lastly, the author modeled the profitability impact of reducing lead times for these items. These models have shown that long lead times and high seasonality are key drivers of large safety stock quantities. Also, with highly seasonal long lead time products, dynamically managing the service level by increasing the service level at the beginning of a product's life and lowering it in its last season of life offers greater profitability than managing to a static service level. Lastly, there is an opportunity to increase the profitability of these products by changing the supply chain to enable dual-sourcing or by reducing lead times.

This following project describes and assesses the current inventory-stocking model used by Commander Submarine Pacific (CSP) to manage its SSN repair parts stocking levels during a deployment work-up period. We also introduce a proposed demand based inventory management tool called Pacific Regional Inventory Stocking Model (PRISM), and compare it with the model currently being used within CSP. This analysis will then evaluate the effectiveness of each system as a management tool utilizing data from CSP's SSN-688 Fast-Attack Submarines. Decision criteria estimated are operational readiness and cost. The results of this comparison also demonstrate a management tool that optimizes inventory stocking. This will increase an SSN-688 submarine's operational readiness while on station and potentially achieve cost savings through optimizing onboard inventory. Recommendations will be provided, based on the results of the comparison, with respect to the feasibility of implementing PRISM, maintaining CSP's current stocking system, or developing a new submarine stocking system to replace the status quo.

Full textThrough digital transformation, company processes that are, or could be, conducted manually are reduced; moreover, human tasks are automated when software-based processes are established. This paper analyzes the adoption of a digital transformation tool to manage inventory through the application of agile models, such as Just-In-Time, and the use of Enterprise Resource Planning (ERP), employing the Deming cycle method, as several unclear empiric processes exist for managing inventory and purchases. It also upholds that as defined processes are established and the companies exert higher control over inventory turnover and outflows, they could apply methods, such as demand forecasting, to avoid stockout, supply shortage, and inventory loss.

Full textOne of the most important problems affecting companies that assemble and market vehicles is stock depletion of finished products. Therefore, many small and medium-sized enterprises (SMEs) have attempted to manage this situation by using tools such as the Q mode, which continuously reviews inventories but does not indicate when and in what quantity a company must supply its sales outlets but requires a more complex level of supplier development and supply chain management efficiency than SMEs can achieve. Likewise, with our proposal we achieved a 50% decrease in stock depletion, based on an analysis of model results, with a confidence level of 95% and a certainty level of 75.30%, projecting a profit of 59000 soles with a return cost of 1.41 and a recovery period of 2 years and 4 months, ensuring both the sustainability and profitability of the proposal.

Full textThe present research seeks to show the importance of applying process management techniques and food safety norms in the operational processes of the supply chain to know the meaning and the need for an integrated hybrid model. The article reviews the sugarcane distillery sector of Peru and its main operational problems. Based on the literature reviewed and discussed with academics who have knowledge of the food supply chain, an integrated hybrid model was developed to help any distillery with lower levels of competitiveness than its competitors in other sectors, such as pisco, applying techniques of process management and food safety to increase the efficiency of liquor distilleries. The findings confirm that distilleries can increase their efficiency, thanks to the higher performance of their operations after their alignment with the integrated model.

Full textIn the past years, logistics in Peru manifested a drop in fourteen positions in the global logistics performance index (LPI) rank, due to the high cost in logistics operations in which 30% comes from distribution centers. Of this volume, 60% represents the workforce cost whereas manual tasks correspond to 42% of the mentioned workforce cost. Order picking in distribution centers is manual in most of the cases. Previous studies have shown the existing relationship between workforce performance and an adequate work method designed with the consideration of human factors, which are described by ergonomics. Nevertheless, change management in an order picking management model has not yet been proven successful. Thus, in the current investigation, an order picking management model that aligns ergonomics and work-study techniques is posed. This will help the performance improvement of pickers; on the other hand, change management will be a supportive technique throughout the validation. The investigation will have a case study in a distribution center where a diagnostic will be run and further on the workforce will be trained with a change management perspective in the new model, which helps reduce the damaged inventory in the logistics operation. Finally, results will be shown, as the model must be evaluated in four aspects: the final percentage of damaged inventory, ergonomics index, efficiency in order picking and total cost of overtime. The main metric for performance evaluation of the model is presented by the reduction of damaged inventory from 4% to 1%.

Full textThis work analyses the viability of an application of the inventory management systematic, which allows to choose and to parameterize replenishment decision models to support supermarket replenishment coordinators in their tasks, using real data. The main objective of this systematic is to contribute to the product availability improvement in the supermarket store considering the following equation: minimize the operational and inventory costs from retail having as a restriction the minimum customer service level in items available at the retail store. This experimental applied research identified CALNEC as the inventory model that presented the best performance in 80% of the sample. The best configuration (configuration of the best performance from all models) showed a saving of 42% compared to the current costs. The current inventory management model presented the worst performance even compared to the non-winners models.

Full textDen kraftigt varierande efterfrågan på snabbt mode gör att aktörer i branschen står inför stora osäkerheter vid initiala lagerallokeringar. Längre in i försäljningscykeln kan lagerobalanser uppstå till följd av avvikelser från den förväntade efterfrågan. För att hantera obalanserna kan företag flytta lager från de regioner med lageröverskott till de som i närtid riskerar att få slut i lager. Sådana flyttar kräver modeller för att avgöra vad och hur mycket som ska flyttas samt när det ska flyttas. Detta examensarbete undersöker hur en sådan modell kan appliceras inom branschen för snabbt mode. Studien genomfördes som en kvantitativ fallstudie i samarbete med Hennes & Mauritz (H&M), en av världens största aktörer inom snabbmodebranschen. En lämplig existerande modell som baseras på konceptet om servicenivå identifierades och anpassades efter H&M:s egenskaper. Till skillnad från majoriteten av modeller i literature användes empiriska sannolikhetsfördelningar för att dynamiskt modellera kortsiktig efterfrågan. Den föreslagna modellen utvärderades och visades föreslå flyttar som genererar signifikanta intäktsökningar drivet av lägre prisnedsättningar. Denna studie skiljer sig från existerande litteratur genom sitt bidrag med en unik fallstudie av hur en modell för lagerflyttar kan appliceras i praktiken samt hur den presterar på empirisk data från en av världens största snabbmodeaktörer.

Full textAtualmente, a redução dos custos de aprovisionamento é bastante importante para qualquer empresa. O custo total de inventário é um dos custos que, se for bem gerido, pode proporcionar uma poupança significativa para as empresas. Este trabalho aborda algumas das classificações e modelos académicos de gestão de stocks e ilustra a sua aplicação numa empresa real, com o objetivo de otimizar a sua gestão de stocks através da redução do seu custo total anual de inventário. Neste estudo optou-se por uma classificação ABC, de forma a ordenar os vários itens em stock consoante a sua relevância financeira. O modelo de gestão de stocks aplicado foi o da Quantidade Económica de Encomenda, que indica qual a quantidade ótima que deve ser encomendada em cada ordem de encomenda, satisfazendo a procura total anual e tendo em conta os custos relacionados com a sua efetivação e com a posse de stocks. Os resultados obtidos pela aplicação de métodos académicos de gestão de stocks demonstraram que pode ser feita uma poupança de mais de 25% relativamente ao custo total anual de stocks registado pela empresa no ano 2015.
Currently, the reduction of supply costs is very important for any company. The total cost of inventory is a cost that if well managed, can provide significant savings for companies. This paper addresses some of the classifications and academic models of stock management and illustrates its application in a real company, in order to optimize their inventory management by reducing its total inventory annual cost. In this study we chose an ABC classification, in order to sort the various items in stock according to their financial importance. The applied inventory management model was the Economic Ordering Quantity, which indicates the optimum amount that must be ordered in each purchase order, satisfying the total annual demand and taking into account the costs related to its ordering and stock ownership. The results obtained by applying academic methods of stock management have shown that it can be made more than 25% in savings when compared to the company's total inventory annual cost in 2015.

Full textAtualmente, a globalização está mais estabelecida do que nunca e com isso observa-se elevado níveis de concorrência entre empresas. Mercados dinâmicos, promovem uma maior competição, exigem padrões cada vez mais elevados de eficiência e qualidade, e tal obriga a otimização da cadeia de abastecimento. Com vista aos resultados, as empresas carecem de maximizar a sua cadeia de valor, com as cadeias de abastecimento e logística desempenhando papéis cruciais. O presente estudo aborda a importância de processos logísticos avançados e modelos de gestão de stocks, enquanto ilustra a sua aplicação numa empresa real, agroindustrial que atua no setor de FMCG (Fast Moving Consumer Goods). Através da análise das suas principais restrições logísticas, foi identificada a gestão de packing materials como a principal limitação para manter os custos baixos. Assim, neste projeto para realização da otimização de gestão de stocks, definiu-se que a procura anual foi igual às vendas de 2016, acrescendo 10%, de desperdício do processo produtivo. Consecutivamente, aplicou-se uma classificação ABC aos valores da procura anual com o objectivo de identificar os itens com maior impacto. Através do modelo de Quantidade Económica de Encomenda (QEE), determinaram-se as quantidades ótimas para um custo total de inventário mínimo, dos artigos definidos como muito importantes. Finalmente, efectuou-se os cálculos do custo total com inventários em 2016 e quais seriam os custos utilizando a QEE, e foi observado que a utilização de um método de gestão de stocks permite à empresa uma poupança anual de cerca de 15,22% face aos custos totais reportados anteriormente.
Today, globalization is more established than ever before and with this we see high levels of competition between companies. Dynamic markets, which fosters competition, demands higher levels of efficiency and quality, for that is required true expertise in supply chain optimization. Deliver a good product or service that consumers' want is not enough to be competitive and sustainable in the long term in this hostile market. Looking for results, companies need to maximize their value chain, with supply chain and logistics playing really important roles. Therefore, the present study addresses the importance of advanced logistics processes and stock management models, while it illustrates its application in a real company, an agroindustrial company operating in FMCG sector. Through the analysis of its main logistic constraints, it was identified the management of packing materials as one limitation to maintain costs low. Hence, in this project for the optimization of stock management, it was defined that the annual demand for packaging materials was equal to the sales of 2016, adding 10% of the average waste process. Thus, ABC classification in order to identify the items with the highest impact. Through the Economic Order Quantity (EOQ) model it was determined the optimal for a minimal cost of, of the articles defined as very important. Finally, we calculated the total cost with inventories in 2016 and what costs would be using the EOQ, we observed that the use of a OEQ method allows the company an annual saving of 15,22% over total costs reported before.

This dissertation studies the application of a periodic review inventory model based on the multiperiod newsboy problem, as an effective alternative to reach a well balanced inventory planning policy of subcontractors primary parts area of the aerospace industry. In Brazil, the aerospace industry is responsible for a large amount of the country exports and this industry competes with other globally aerospace supply chains in a scenario increasingly turbulent and demanding for fast deliveries, with high quality levels and low cost. The purpose of this work is to study and propose this alternative for optimizing the inventory planning by means of a quantitative approach, applied in a primary parts sector of the aerospace industry, it will focus in a specific group of items with high annual demand value. The main objective of this approach is to balance the high inventory costs with a high service level demanded in this industry, and efficiently respond the stakeholders expectations, with superior performance of the usual models adopted by this industry, and give a better support to the decision makers in a tactical-operational level. The result obtained show the potential of the method to improve the performance of these inventory management and planning systems.
Este trabalho estuda a aplicação de um modelo analítico de revisão periódica de estoques, baseado no problema do jornaleiro multiperíodo (Multiperiod Newsboy Problem), como uma alternativa efetiva para determinação da política de planejamento de estoques do setor de peças primárias subcontratadas da indústria aeroespacial. No Brasil, a indústria aeroespacial é responsável por grande parte das exportações do país e compete globalmente com outras cadeias aeroespaciais num cenário cada vez mais turbulento e exigente por entregas rápidas, com altos níveis de qualidade e baixos custos. O objetivo deste trabalho é estudar e propor essa alternativa para otimizar o planejamento de estoques por meio de uma abordagem quantitativa, aplicada no setor de peças primárias da indústria aeroespacial, para um grupo de peças com características especificas, principalmente as de alto valor para demanda anual. O intuito desta abordagem é equilibrar os altos custos de estoque com os altos níveis de serviço exigidos por esta indústria, e responder de forma eficiente às expectativas dos stakeholders, com desempenho superior aos modelos atualmente utilizados no setor e auxiliar de forma mais precisa e sistematizada a tomada de decisão no nível tático-operacional. Os resultados obtidos mostram o potencial do método para melhorar o desempenho desses sistemas de gestão e planejamento de estoques.

Full textIn such an important area and with great contribution to the GDP of the country, as it is in the mining sector, to carry out a supply management model that helps to generate greater profitability, is to have won the lottery. That is why, said management model is based, firstly, on carrying out a kraljic matrix to obtain a purchasing strategy, secondly, an approval of suppliers who are mainly willing to work with a VMI (Managed Inventory) system is carried out. by suppliers), this process has the purpose of reducing the delay time of acquiring the components of the R1600 charger in order to meet the customer in 52 days, this date is established by the company under study, which was referenced by the sector of the same item that on average is 45 days. Currently, the delivery time of the R1600 charger to the client is 72 days, being the company that delays the longest in delivery, this delay is due to the delay in the acquisition of parts and pieces. Faced with this problem, an innovative technique is proposed that consists of carrying out a set of methodologies, the Kraljic matrix, then developing the supplier approval and VMI software. What generated being able to meet the client in the agreed time without generating contract penalties, reducing the costs of overtime by the operators and increasing the profits of the company under study.

Full textAs questões relacionadas com a melhoria da gestão de stocks têm assumido uma importância maior no seio das organizações, e nesse sentido têm-se desenvolvido estudos com vista a procurar soluções para minimizar o Custo Total de Aprovisionamento. No presente trabalho de projeto pretende-se demonstrar que é possível reduzir o atual Custo Total de Aprovisionamento da empresa Imarpec, sendo que para isso foram utilizados modelos académicos, como o QEE (Quantidade Económica de Encomenda) para encontrar a resposta à pergunta "Quanto encomendar?", que satisfaça a procura anual e que ao mesmo tempo minimiza os custos, assim como o MPE (Modelo do Ponto de Encomenda), de forma a encontrar a resposta à pergunta "Quando encomendar?", determinando o nível de stock para efetuar-se nova encomenda. Para este estudo foi escolhida a Classificação ABC, ferramenta útil para distinguir os três tipos de itens em inventário, de acordo com o peso financeiro que cada um representa, focando depois nos itens tipo A para a análise de custos. Os resultados obtidos permitem tirar conclusões sobre a importância que a gestão de stocks tem nas empresas, devendo ser feita de forma diferenciada para cada classe de stock, sendo os itens tipo A, aqueles que merecem uma gestão mais rigorosa pelos custos financeiros que incorrem. Por fim é apresentada uma proposta específica que a empresa pode seguir com vista a melhorar a gestão de stocks atual, permitindo obter uma poupança até 86% relativamente ao Custo Total de Aprovisionamento incorrido em 2016.
The related issues with stocks management improvement has considered an huge importance in the center of organizations, thus has been developed studies to looking for solutions to minimize the total inventory cost. In the present work project, intend to show that is possible reduce the current total inventory cost of Imarpec, then are used academical models, than EOQ (Economic Order Quantity) to find the answer to the question "How much to order?", that both satisfy annual demand and minimize costs, as well as ROP (Reorder Point) model, to find the answer to the question "When to order?", to determine the stock level and place new order. For this study was chosen the ABC classification, it's a useful tool to distinguish the three types of itens in inventory, according with the financial proportion that each one represent, and then focused in itens type A to costs analysis. The results obtained allow drawing conclusions about the importance that stocks management have in companies, that should be done in a differentiated way to each classe of stock, and classe A are the ones that deserve more rigorous stocks management because of financial costs that incur. At the final, is presented a specific proposal that enterprise can follow to actual stocks management improve, allowing achieve a save until 86% about total inventory cost incurred in 2016.
