Many companies have automated their inventory management processes and rely on an information system in critical decision making. However, if the information is inaccurate, the ability of the system to provide high availability of products at the minimal operating cost can be compromised. In this paper, analytical and simulation modelling demonstrate that even a small rate of stock loss undetec...

This paper derives optimal production-shipment policy for a single-producer multi-retailer integrated inventory model with rework. We assume that a product is manufactured by a producer. All items are screened for quality assurance. Random defective items will be picked up and reworked in the same cycle when regular production ends. Upon entire lot is quality assured, multiple shipments are del...

We study a single-product fluid-inventory model in which the procurement price of the product fluctuates according to a continuous time Markov chain. We assume that a fixed order price, in addition to state-dependent holding costs are incurred, and that the depletion rate of inventory is determined by the sell price of the product. Hence, at any time the controller has to simultaneously decide ...

Background: There is limited understanding about the development of the online one-stop shops for evidence in a limited-resource setting, such as Uganda. This study aimed to provide a comprehensive account of the development process of the online resource for local policy and systems-relevant information in this setting. Methods: We utilized a case study design to address our objective where ...

In this research, an integrated inventory problem is formulated for a single-vendor multiple-retailer supply chain that works according to the vendor managed inventory policy. The model is derived based on the economic order quantity in which shortages with penalty costs at the retailers` level is permitted. As predicting customer demand is the most important problem in inventory systems and th...

This paper deals with the single machine multi-product lot scheduling problem in which defective items are produced in any production run of each product. We have adopted the common cycle scheduling policy and assumed that the setup times for production of each product can be non-zero. Further, we have assumed that defective items will be reworked and the inspection costs during the normal prod...

a facile co-precipitation method for the synthesis of well-dispersed ndfeo3 nanocrystals is developed in the presence of octanoic acid as surfactant. co-precipitation can produce fine, high-purity, stoichiometric particles of single and multicomponent metal oxides. the product is characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd), scanning electron microsc...

A result in the Bayesian inventory management literature is: If lost sales are not observed, the Bayesian optimal inventory level is larger than the myopic inventory level (one should “stock more” to learn about the demand distribution). This result has been proven in other studies under the assumption that inventory is perishable, so the myopic inventory level is equal to the Bayesian optimal ...

The single-vehicle cyclic inventory routing problem (SV-CIRP) is concerned with a repeated distribution of a product from a single depot to a selected subset of retailers having stable demands. The objective is to determine the subset of retailers to cyclically replenish, the quantities to be delivered to each, and to design the vehicle routes so that the expected total distribution and invento...
