Economic production quantity model for items with imperfect quality
Abstract The assumptions necessary to justify the use of economic production quantity (EPQ/EOQ) models are rarely met. To provide mathematical models that more closely conform to actual inventoriesExpand

Economic order quantity for items with imperfect quality: Revisited
We rectify a flaw in an economic order quantity (EOQ) model with unreliable supply, characterized by a random fraction of imperfect quality items and a screening process, developed by Salameh andExpand

Coordinating a three-level supply chain with multiple suppliers, a vendor and multiple buyers
This paper investigates the coordination of order quantities amongst the players in a three-level supply chain with a centralized decision process. The first level of the supply chain consists ofExpand

Environmentally responsible inventory models: Non-classical models for a non-classical era
Mathematical models of inventory typically include the three inventory associated costs of surplus, shortage and ordering. These classic inventory models are then analysed so as to choose inventoryExpand

Incorporating human factors in order picking planning models: framework and research opportunities
Order picking (OP) activities, essential to logistics operations, are laborious and time-intensive. Humans are central actors in the OP process and determine both OP effectiveness and efficiency.Expand

Lot sizing with learning and forgetting in set-ups and in product quality
Abstract Managers at manufacturing firms make every effort to improve the performance of their operations through the adoption of continuous improvement programmes, e.g. reducing set-ups times,Expand

A production/remanufacturing inventory model with price and quality dependant return rate
Inventory management of produced, remanufactured/repaired and returned items has been receiving increasing attention in recent years. The available studies in the literature consider a productionExpand

Production breaks and the learning curve: The forgetting phenomenon
Abstract In this paper, the forgetting slope is shown to be mathematically dependent on the following factors: 1. (1) the learning slope, 2. (2) the quantity produced to date, and 3. (3) the minimumExpand

A review of the extensions of a modified EOQ model for imperfect quality items
Imperfect items in the raw material and production stages of a supply chain directly impact the coordination of the product flow within a supply chain. In response to this concern, production andExpand

The EOQ repair and waste disposal model with switching costs
This paper addresses the problem of determining the optimal batch sizes for production and recovery in an EOQ (economic order/production quantity) repair and waste disposal model context. This paperExpand
