Abstract:

In this paper, the aviation supplies inventory in maintenance process is taken as the study subject. Based on reasonable hypothesis, aviation supplies consuming process in a fixed period is regarded as stochastic process, and inventory process and inventory control system model are built. Take tire inventory as an example and then the model parameters have been identified. On this basis, aviation supplies inventory control system is designed by means of stochastic control theory, which could optimize inventory quantity. Finally, simulate inventory control process by MATLAB simulation software. The results show that inventory variance and average inventory quantity decrease, which can significantly reduce the stock fund and maintenance cost.

Abstract:

Now-a-days, supply chain management is one of the crucial factors in business for identifying the flow of goods, raw material storage, movement of products and inventory process so on. The main aim of the supply chain management process is to provide the valuable business services, infrastructure, logistic control and inventory control to the business for improving the business. Among the various supply chain factors, inventory control is one of the difficult tasks in supply chain management process because of high cost inventory, consistent stockouts, low rate of inventory turnover, high value of obsolete inventory, maximum working capital, huge cost for storage and lot customers. Then, several supply chain management techniques are introduced in traditional to control the inventory process but they are failing to detect with greatest accuracy due to the low convergence rate in computation techniques. So, in this paper introduce the effective and optimized neural network computational approach for managing the inventory control. In addition to this, the system ability to select the product based on the few factors that improve the inventory control system accuracy. Then the excellence of the system is evaluated using experimental analysis and respective performance metrics.

Abstract:

Inventory plays an important role in a company's production process, especially in the sustainable manufacturing industry. The inventory of raw materials such as rayon, polyester, and cotton is an essential element that needs to be controlled to maintain a smooth production process. This research aims to plan and control raw materials through the min-max method, with a focus on evaluating inventory control to identify and overcome existing problems in the raw material warehouse at a yarn and textile manufacturing company. The results show that each type of raw material has a different reorder level, which guides the company in avoiding the risk of shortage or excess stock. By applying the right reorder level, the company can improve its production efficiency and inventory management. This research contributes to the practice of inventory control in the sustainable manufacturing industry, which supports operational stability and minimizes resource wastage. The implications of the findings could expand the application of min-max method-based inventory control in other industries to support operational sustainability.

Abstract:

The inventory control system has a strategic role for the business in managing inventory operations. Management of conventional inventory creates problems in the stock of goods that often runs into vacancies and excess goods at the retail level. This study aims to build inventory control system that can maintain the stability of goods availability at the retail level. The implementation of Vendor Managed Inventory (VMI) method on inventory control system provides transparency of sales data and inventory of goods at retailer level to supplier. Inventory control is performed by calculating safety stock and reorder point of goods based on sales data received by the system. Rule-based reasoning is provided on the system to facilitate the monitoring of inventory status information, thereby helping the process of inventory updates appropriately. Utilization of SMS technology is also considered as a medium of collecting sales data in real-time due to the ease of use. The results of this study indicate that inventory control using VMI ensures the availability of goods ± 70% and can reduce the accumulation of goods ± 30% at the retail level.

Abstract:

Inventory management is a challenging problem area in supply chain management and companies need to have inventories in warehouses in order to satisfy customer's needs. Meanwhile, these inventories have holding costs and this is a frozen fund that can be lost. Therefore, the task of inventory management is to find the right quantity of inventories that will fulfill the demand with the right price, avoiding overstocks. The aim of this paper is to carry out a comparing study of continuous inventory control policies in a stochastic environment of demand and lead time, in order to find out the impacts of the decision variables of each inventory control policy. For this purpose, the discrete event simulation approach has been chosen to generate various scenarios of inventory control policies of the procurement process by taking into account the production planning of the manufacturing company. The comparison of these configurations based on the essential key performance indicators of the supply chain, namely the cost and service level.

Abstract:

This article deals the problem of optimally controlling the perishable inventory with exponential perishable rate and exponential lead time in a finite capacity retrial service facility system. Arrival of demands to the system is assumed as Poisson and service times are assumed to follows an exponential distribution. Here, the customers are not allowed to form a queue. A customer who sees the server busy joins the orbit and reattempts the system with exponential distributed time. For the given values of maximum inventory and reorder level, we determine the optimal ordering policy at various instants of time. The system is formulated as a Semi-Markov Decision Process and the optimum inventory control to be employed by using linear programming method so that the long–run expected cost rate is minimized. Numerical examples are provided to illustrate the model.

Abstract:

The concept of minimum display quantity (MDQ) is unavoidable in brick-and-mortar retailing format owing to which, retailers need to ensure a minimum level of inventory displayed at each store irrespective of the revenue or inventory turns generated by a particular store. It is observed that majority of bricks-and-mortar retailers in India assume;(a) existing inventory management system is ideal to their store, (b) software solutions record accurate inventory movement, (c) involving store management team in inventory related decision making is risky/biased and most importantly (d) loss of sale due to stockouts is inevitable. Such assumptions and widely followed practice have created a predisposition and mindset in store managers and they believe that their store delivers revenue and profit to the best of its potential with the inventory which is made available to them through existing inventory management system and we cannot avoid a number of instances consumers are unsatisfied due to stockout situations. In this research, we have analysed the existing decision-making process and control systems related to inventory management of a select retailer, attempted to design a new framework and applied the same through an experiment to evaluate the change in (a) overall store profitability and (b) inventory related key performance indicators.

Abstract:

This control study was carried out at the PT AW Printing Company which had quite a number of problems that were often used from its store. The approach is action research with a focus on distributing and storing raw materials for lean manufacturing. The analysis is production staff who need a lot of excess paper that can still be used, and use too much paper in print production. The company then enforces a new procedure that is not possible to get printouts that can still be used using the principle of 7 waste, to use those that cannot be used. Scope of study for the process of distribution, selection and use of raw materials, understanding the meaning of supply preparation (logistics) by employees and delivery of finished products. The results of the study show that product delivery is low to customers because of the low inventory turnover. In the PT XY preparation division, there are approximately 80% of which have potential factors. The contributing factors are long demand for goods, unclear forecasting, not understood standards for demand, inaccurate recording, vital factors affecting raw materials is the selection and use of raw materials.

Abstract:

Controlling the amount of inventory value is not an easy thing for companies, starting from recording the purchase price of goods, determining prices to presenting these inventories into financial statements. To facilitate inventory control, a decision support system is needed that aims to simplify the inventory control process which is expected to help the problems that exist in the company. The same thing is needed by PT. Source of Mutual Sustenance. This private company engaged in the distribution of food products also needs a decision support system that can control the inventory of goods so as to facilitate the process of controlling inventory. Previously, inventory at PT. Sumber Rezeki Bersama experienced problems where the company did not prioritize ordering goods, especially those with the highest sales. So that when there are many messages from consumers for these goods, the company cannot fulfill orders on time, given the stock of goods that are not always available (because they are not prioritized).

Full text

Abstract:

Demand variability directly affects inventory management. The variability of intermittent demand causes high lost sales or holding costs. While lost sales reduce customer satisfaction, keeping excessive stock also creates high costs for companies. This situation can be prevented with an appropriate inventory policy. In this study, a Markov-based proactive inventory management approach supported by metaheuristic methods is proposed in the inventory management of intermittent demands. The main contribution of the proposed approach is to find a lower and upper limit for stock by modeling the intermittent demands in the past period with the Markov process. With these optimized limits, it is aimed to balance the largest costs caused by intermittent demands, namely stock and lost sales costs. The intermittent demands used were randomly generated in 4 different sizes from small to large. The proposed approach contributes to inventory management by minimizing the negativities caused by demand variability through the Markov process. A mathematical model has been proposed for stock level optimization, but no feasible solution has been found. The mathematical model was transformed into a fitness function and a solution was provided with the Tabu Search Algorithm and Simulated Annealing. The inventory management process of intermittent demand was first evaluated without the Markov approach, and then the Markov approach was included in the process. The results showed that the Markov approach was a good tool for inventory management of intermittent demand. When the results were examined, the stock limits computed with the Markov process balanced the increased inventory cost and lost sales costs due to intermittent demand.

Abstract:

In today’s fast-paced business environment, efficient inventory management is crucial for minimizing operational waste and maximizing productivity. Traditional inventory control systems often suffer from inefficiencies such as overstocking, stockouts, and delays due to manual processes. To address these challenges, this presents a process automation framework for smart inventory control, integrating JIRA-driven workflows with lean practices to enhance efficiency, transparency, and agility in inventory management. The proposed framework leverages JIRA’s automation capabilities to streamline key inventory processes, including demand forecasting, stock tracking, procurement approvals, and replenishment workflows. By utilizing JIRA’s Kanban boards, automation rules, and reporting features, organizations can achieve real-time visibility into inventory levels, ensuring timely decision-making and reducing waste associated with excess inventory or shortages. Additionally, Lean principles such as just-in-time (JIT), continuous improvement (Kaizen), and waste elimination (Muda) are embedded into the workflow design to enhance operational efficiency. This outlines the step-by-step implementation of the framework, mapping inventory control processes to JIRA-driven automation and integrating with enterprise resource planning (ERP) and warehouse management systems (WMS). A case study is presented to demonstrate real-world applications, highlighting tangible benefits such as faster inventory turnover, improved accuracy, and cost savings. Key challenges, including system integration and user adoption, are also discussed, along with mitigation strategies. By combining workflow automation and Lean methodologies, the proposed framework provides a scalable and adaptive solution for modern inventory control. Furthermore, emerging trends such as AI-driven inventory optimization and IoT-enabled real-time stock monitoring are explored as future enhancements. This offers practical insights for organizations seeking to reduce operational waste and improve supply chain efficiency through smart automation solutions.

Abstract:

Introduction: inventory control is the internal management of the merchandise or stock that exists in the company. The inventory, regardless of its function or nature, is an ordered, valued and classified list within a company or premises.Objective: to characterize aspects related to the inventory control process in companies.Method: a review of the bibliography available in databases such as SciELO, Scopus and ClinicalKey was carried out, of which a total of 14 related articles were consulted, empirical methods such as logical history and analysis and synthesis were used.Results: there is no unique formula or method for carrying an adequate stock, but a correct application of those defined in the company. A Manual is a document that allows to synthesize, systematize and standardize procedures, norms, policies. A policy is a light that helps to see the path where you want to go, seeking to avoid making mistakes. Maintaining controls, policies, norms in the inventory is of utmost importance not only for its control but also helps in generating dividends for the company. Conclusions: this process is currently deficient in many companies; adequate inventory control is reflected in cost reduction, improved cash flow and customer service, and increased operational efficiency and decision-making

Abstract:

The study aims to test the effectiveness of the implementation of several inventory control methods to improve the smooth operation in a trading company of industrial equipements components that have difficulty in maintaining inventory data accuracy, inventory shortages and in other hand excess unrequired inventory. The research data used is taken from the ERP report data and manual reports created by the perpetrators of the operational activities of the Inventory Control for the period 2016 - 2018. The sampling method used is purposive sampling of the product sales data in years 2016 – 2018 as much as 2498 Stock Keeping Unit (SKU) which is then processed using the method of ABC analysis and FSN (Fast Moving, Slow Moving and None Moving) analysis to get 10 SKUs that belongs to the category A and F (Fast Moving) group as a sample of research. The research method uses the Quantitative method with the use of ABC analysis, Forecasting and Economic Order Quantity. The results shows that the implementation of ABC analysis effectively reduced the workload of periodic counting and is able to improve data accuracy to be higher level. The exponential smoothing forecast method shows the least gap to the actual value and EOQ effectively optimizes ordering and holding costs and reduces the risk of failure in Inventory Control and positively affects the smoothness of the operation process.

Abstract:

AbstractWe consider continuous review inventory systems with general doubly stochastic Poisson demand. In this specific case the demand rate, experienced by the system, varies as a function of the age of the oldest unit in the system. It is known that the stationary distributions of the ages in such models often have a strikingly simple form. In particular, they exhibit a typical feature of a Poisson process: given the age of the oldest unit the remaining ages are uniform. The model we treat here generalizes some known inventory models dealing with partial backorders, perishable items, and emergency replenishment. We derive the limiting joint density of the ages of the units in the system by solving partial differential equations. We also answer the question of the uniqueness of the stationary distributions which was not addressed in the related literature.

Abstract:

Purpose: The aim of this article is to present the determinants of a properly conducted inventory process in local governments and to demonstrate the role of local Government Shared Service Centers (SSCs) in improving the quality of the inventory process. Design/methodology/approach: The authors, based on a research tool - a case study, presented the results of inventory conducted in a rural municipality using a selected municipality in the Kuyavian-Pomeranian Voivodeship as an example. The inventory process was preceded by an analysis and development of appropriate internal documents, as well as employee training. After the inventory was completed, surveys were conducted among the employees involved in this process. The collected responses and the conducted literature studies, especially the analysis of post-control findings of national control organizations such as the Regional Audit Offices, allowed for drawing conclusions and achieving the set research goal. Research limitations/implications: The conducted studies on the literature related to the subject and the available post-control findings in the area of public finances of local government units allow for drawing conclusions regarding the complexity of the inventory process. Despite the legally and substantively well-defined process of conducting inventory in the Accounting Act, public entities, and particularly the local government units examined in this article, still make many mistakes in this process. The inventory process is especially crucial for the accurate preparation of financial statements for entities, including local government units. Originality/value: The research highlights the need to distinguish between the organizational and substantive aspects of the inventory process. While local government units can handle the substantive part (selecting proper methods and principles for individual assets), the organizational aspect poses challenges, especially in rural municipalities with complex structures and limited staff. The study reveals the close connection between the inventory process and internal documents like Municipal Office Regulations, employee records, and asset responsibilities. The findings identify problematic areas in the inventory process. The authors suggest that utilizing SSCs could enhance efficiency and security. Keywords: inventory, Local Government Shared Services Centers, public finance, public management. Category of the paper: research paper.

Abstract:

Information system innovation progress is turning out to be speedier and simpler to use. In many cases, there are an organization that still utilize the customary route in preparing their information.Â Customary routes will require people to move from one place to another to achieve their goals. In the case of Finance Department, UiTM Kampus Kuala Terengganu, the manual process involving the staffs to fulfill and submit the form and officer will approval and validation. The storekeeper will verify the availability of the item in the store. Using manual processes consumes a lot of time, high risk of human error and involves a lot of papers as well as files. Therefore, Bendahari Inventory Control System (BICS) was proposed to help the Finance Department to be more systematic in handling the inventory control. The implementation of the Waterfall Model in this research was turned to be useful and appropriate to help building up the system.Â Â

Abstract:

Purpose This paper aims to optimise the dynamic performance of production–inventory control systems in terms of minimisation variance ratio between the order rate and the consumption, and minimisation the integral of absolute error between the actual and the target level of inventory by incorporating the Pareto optimality into particle swarm optimisation (PSO). Design/method/approach The production–inventory control system is modelled and optimised via control theory and simulations. The dynamics of a production–inventory control system are modelled through continuous time differential equations and Laplace transformations. The simulation design is conducted by using the state–space model of the system. The results of multi-objective particle swarm optimisation (MOPSO) are compared with published results obtained from weighted genetic algorithm (WGA) optimisation. Findings The results obtained from the MOPSO optimisation process ensure that the performance is systematically better than the WGA in terms of reducing the order variability (bullwhip effect) and improving the inventory responsiveness (customer service level) under the same operational conditions. Research limitations/implications This research is limited to optimising the dynamics of a single product, single-retailer single-manufacturer process with zero desired inventory level. Originality/value PSO is widely used and popular in many industrial applications. This research shows a unique application of PSO in optimising the dynamic performance of production–inventory control systems.

Abstract:

Abstract: The rapid rise of e-commerce has increased pressure on warehousing operations, where inventory accuracy is crucial for timely order fulfillment and cost control. Despite advanced Warehouse Management Systems (WMS), issues like misplacements, bin overstuffing, and picking errors persist. This study applies the Six Sigma DMAIC framework to analyze and improve inventory accuracy in e-commerce warehousing, using insights from a leading Indian e-commerce company and simulated operational data. Key issues were identified using Pareto analysis, with inventory misplacement accounting for over 40% of errors. Root causes were explored through Fishbone diagrams, 5 Whys, and FMEA. Solutions are proposed across people (training, SOP compliance), process (task validation, audits), and infrastructure (dynamic binning, visual aids), with control mechanisms such as KPI dashboards and scan enforcement. The study offers a scalable, data-driven approach to smart inventory management applicable to major platforms like Amazon, Flipkart, and Blinkit.

Abstract:

Increasing the rate of converting raw material into finished product and delivering it on time is a main driver for each manufacturing industry to achieve continuous improvement in its business operation. This case study demonstrates the improvement of the work-in-progress inventory in a non-lean company seeking to adopt lean management. Introducing the value stream mapping (VSM) lean technique to identify the waste in the current production operation. A selection of lean tools such as Kanban card, supermarket racking and one-piece flow are applied to control and monitor the WIP inventory after justification of the factors (process cycle time, production facilities layout and facilities capacity allocation) that influence the change from the current production operation situation.The construction of the current VSM had identified the major waste in WIP inventory handling in the final fabrication process. The fluctuation of WIP inventory has been resolved by the implementation of supermarket racking; therefore, an improvement base for WIP inventory control has been established. Throughout this study, the lean management concept had been fostered into the production floor team and will continue developing to the organization.

Abstract:

A good raw material and consumables control planning system is important in the production process so that the process runs according to schedule and target. Brake system company is a manufacturing company engaged in brake systems. Concerning the control of consumable material, this company often experiences overstock in warehouses, causing an overrun in inventory costs and investment cannot develop. One of these conditions can be influenced by the ordering method applied by the company which is still not appropriate. The purpose of this study is to find out and provide proposed to companies related to the cost of consumable inventory by comparing the three methods of determining lots based on Fixed Order Quantity (FOQ), Economic Order Quantity (EOQ), and Fixed Order Quantity Proposed (FOQ Proposed) is the FOQ method combined with the Lot for Lot (LFL) principle to determine the method with the most optimal inventory cost. From the results of the study, it is known that the Proposed FOQ method has the lowest total inventory cost compared to the other two methods. The proposed FOQ approach could reduce inventory costs by up to one-third times the previous cost.
