RGSGAN–MACRNet: A More Accurate Recognition Method for Imperfect Corn Kernels Under Sample-Size-Limited Conditions [PDF]

Foods
Under sample-size-limited conditions, the recognition accuracy of imperfect corn kernels is severely degraded. To address this issue, a recognition framework that integrates a Residual Generative Spatial–Channel Synergistic Attention Generative ...

Replenishment policies for imperfect inventory system under natural idle time and shortages [PDF]

Yugoslav Journal of Operations Research, 2020
Most of the offline businesses do not run continuously for the entire day, therefore, the concept of idle time is inevitable. Natural idle time is referred to as the closing time when no demand is being fulfilled by the seller, the unproductive time when

Proposing an Economic Order Quantity (EOQ) model for imperfect quality growing goods with stochastic demand [PDF]

مدیریت تولید و عملیات, 2022
Purpose: The main aim of inventory control and production planning problems is to optimize the economic quantity of the order or determine the size of the production batch according to the capacities and limitations to minimize the total costs related to

An Inventory Model in a Three-Echelon Supply Chain for Growing Items with Imperfect Quality, Mortality, and Shortages under Carbon Emissions When the Demand Is Price Sensitive

Mathematics, 2022
This research develops an optimization model for growing items in a supply chain with three stages: farmer, processor, and retailer while considering imperfect quality, mortality, shortages with full backordering, and carbon emissions.

Economic order quantity model for imperfect quality items with environmental regulations [PDF]

Yugoslav Journal of Operations Research, 2022
In real life situation, advance technologies are used to produce items but due to some technical error imperfect items are produced. Therefore it is necessary to separate these imperfect items by complete screening process and such items are ...

Economic production quantity concerning learning and the reworking of imperfect items [PDF]

Yugoslav Journal of Operations Research, 2012
The classical economic production quantity (EPQ) model assumes that items produced are of perfect quality and the production rate is constant. However, production quality depends on the condition of the process.

An Inventory Model for Imperfect Quality Products with Rework, Distinct Holding Costs, and Nonlinear Demand Dependent on Price

Mathematics, 2021
Traditionally, the inventory models available in the literature assume that all articles in the purchased lot are perfect and the demand is constant. However, there are many causes that provoke the presence of defective goods and the demand is dependent ...
