Abstract:

In the classical economic order quantity (EOQ) inventory model, it was assumed that the retailer must pay for the received items immediately. However, in practice, the supplier not only allows retailer to settle the account after a certain fixed period but also may offer a cash discount to encourage the retailer to pay for his purchases as soon as possible. On the other hand, it is common practice in most inventory systems to hold excess stocks in a rented warehouse whenever the storage capacity of the owned warehouse is insufficient. Therefore, the purpose of this paper is to establish an EOQ

Abstract Decision makers in various sectors, such as manufacturing and transportation, strive to minimize downtime costs. Often, brief-planned stoppage times allow for changes in shifts and line configurations and longer periods are scheduled for major repairs. It is quite important to proactively make use of these downtimes to reduce the costs of unexpected downtimes due to failures. Among many aspects, the availability of spare parts significantly affects the operational costs of such systems. Current sensor technologies enable the condition monitoring of critical components and degradation-

Abstract:

This study explores the association between working capital management and the profitability of textile firms in Pakistan. The efficiency of working capital management is reflected by three variables: cash conversion efficiency, days operating cycle, and days of working capital. We use return on assets, economic value added, return on equity, and profit margin on sales as proxies for profitability. A balanced panel dataset covering 160 textile firms for the period 2000–05 is analyzed and we estimate an ordinary least squares model and a fixed effect model. Return on assets is found to be signi

This paper presents an analytical and numerical analysis of an inventory model incorporating credit periods, focusing on major business concerns that face cash flow constraints. In such circumstances, credit periods serve as a crucial tool for determining optimal production inventory strategies. The foremost objective of the research is to assess the benefits accrued by both producers and buyers within a fixed credit period framework. The analytical solution model developed in this study aims to optimize production inventory costs by considering the cycle periods and interest earned during sho

A single item, single cycle economic production quantity model for perishable products is proposed where the demand is two-component and stock dependent. The production inventory scenario of products like cake, bread, fast foods, fishes, garments, cosmetics etc in the festival season is considered. The profit function is formulated under the assumption that the time period of the festival seasons is fixed and the display capacity of the produced item is limited. In the formulation process, to introduce more flexibility, a goal programming technique is incorporated to achieve the producer's des

In this inventory model, the deterioration rate follows a three-parameter Weibull distribution.

The paper investigates a single period imperfect inventory model with price dependent stochastic demand and partial backlogging. The backorder rate is a nonlinear non-increasing function of the magnitude of shortage. Two special cases are considered assuming that the percentage of defective items follows a truncated exponential distribution and a normal distribution respectively. The optimal order quantity and the optimal mark up value are determined such that the expected total profit of the system is maximized. Numerical example is given to illustrate the proposed model which is compared wit

One more constraint is taken into consideration: once the bottle of the medicine is opened, it has to be given to a fixed number of patients requiring swine flu vaccine simultaneously, failing which, the proportion of unused medicine becomes obsolete a

Introduction: Inventory management is a critical challenge for small and medium-sized enterprises (SMEs), particularly in the food sector, due to the perishable nature of goods and fluctuating demand. Traditional inventory models often fail to adapt to these dynamic conditions, leading to inefficiencies and increased costs. Objectives: This study aims to develop a cost-effective and adaptive framework for inventory optimization in food-sector SMEs. The focus is on applying deep reinforcement learning techniques in single-stage or single-agent environments to simplify complex inventory systems

Abstract:

This study presents a novel approach to a mixed-integer linear programming (MILP) model for periodic inventory management that combines reinforcement learning algorithms. The rolling horizon method (RHM) is a multi-period optimization approach that is applied to handle new information in updated markets. The RHM faces a limitation in easily determining a prediction horizon; to overcome this, a dynamic RHM is developed in which RL algorithms optimize the prediction horizon of the RHM. The state vector consisted of the order-up-to-level, real demand, total cost, holding cost, and backorder cost,

To achieve the objective, analytical formulas of the EOQ model based on the asymptotic approach under conditions of minor changes in the input parameters were obtained. The discrete increase in the order fulfillment costs and the inventory storage costs which depend on the "small parameter" as well as periodic fluctuations in demand for products were taken as variable parameters of the system.
