Background: The present work is related to a project developed in a company dealing with the security and communication systems, fire alarms, and electronic displays sector, located in the district of Aveiro. This work aims to improve the logistics flow of material reception in the warehouse of...

Das Ziel dieser Arbeit ist es Verfahren zu entwickeln, welche Lösungen zur Re-duzierung des Bestandes bei den obsoleten Artikeln mit unregelmäßigem oder keinem Bedarf anbieten werden. Hierfür erarbeitete der Autor zwei Algorithmen, welche Berechnung der Logistikkosten beinhalten. Die...

Inventory affects the production process and supply chain activities. Integrated decision inventory improves performance and optimizes supply chain activities. However, its disadvantage is the Integrated Procurement Production (IPP) inventory model, which manages the raw material inventory in...

Effective management of perishable inventory systems is often strewn with challenges, especially when a strong trade-off relationship exists between shortage and wastage of perishables: A smaller inventory increases the chance to lose sales (leading to higher expected shortage cost), while a...

Purpose: A rising global container throughput has necessitated the need for more efficient terminals. This work focuses on identifying past developments, important methods, key performance indicators and the future trends, related to the main decision tasks in an inland rail-road terminal. Prime...

Purpose: To enable reliable food supply and to remain competitive, grocery retailers need to operate efficient distribution networks. Therefore, the purpose of this paper is to develop and apply a multi-criteria evaluation framework considering the complexity of grocery retail warehouses while...

The inventory carrying cost has been assumed uniform for all products in an organization or a warehouse. This assumption is not valid for a diversified range of items in an organization or warehouse. This paper tested this hypothesis of variations in inventory holding costs in a warehouse in two...

Epidemics require dynamic response strategies that encompass a multitude of policy alternatives and that balance health, economic and societal considerations. We propose a simulation-optimization framework to aid policymakers select closure, protection and travel policies to minimize the total...

Purpose: The objective of this research was to implement new inventory management in a footwear company through the analysis of indicators obtained from inventory data collection. Design/methodology/approach: The methods of ABC analysis, demand forecasting, safety stock, reorder point and...

This paper analyses literature contributions in the search for safety stock problem under uncertainties and risks in the procurement process, focusing on the dimensioning problem (determination of the safety stock level). We perform a systematic literature review (SLR) from 1995 to 2019 in...

Because prior knowledge may not generalize to the COVID-19 setting, scholars are racing to test the efficacy of existing theoretical frameworks during COVID-19. Most business studies are conceptual or surveys of damage. The main purpose of the paper is to extend the forthcoming stream that tests...

This paper presents a travel time model for multi-deep AS/RS, which determines the average travel times during a single command storage or retrieval and a dual command cycle. The model can determine the relocation probability, the number of expected relocations and the travel times in storage...

The VSTOXX index tracks the expected 30-day volatility of the EURO STOXX 50 equity index. Futures on the VSTOXX index can, therefore, be used to hedge against economic uncertainty. We investigate the effect of trader inventory on the price of VSTOXX futures through a combination of stochastic...

Inventory management is becoming very challenging for the retailer over the years due to the uncertainty in the demand and supply of products in financial risk and management systems. In a competitive market, running a business smoothly in a highly suitable place is day by day becoming tough due...

Durch die Digitalisierung ergeben sich neue Möglichkeiten der Optimierung der gesamten Wertschöpfungskette von Unternehmen. Spezialisierte Anbieter haben dies erkannt und dafür digitale B2B-Lösungen entwickelt. Unternehmen müssen entscheiden, ob sich der Einsatz der neuen Technologien für...

In this study, we are primarily motivated by the research problem of recognizing heterogeneous customer behavior towards waiting for order fulfillment under the 'threshold rationing policy' (also known as the 'critical level policy'), and aim to find its effect on system stock levels and...

We consider an assortment optimization problem where a customer chooses a single item from a sequence of sets shown to her, while limited inventories constrain the items offered to customers over time. In the special case where all of the assortments have size one, our problem captures the...

Storage technologies – such as batteries or hydrogen – are crucial for a transition towards a low-carbon economy as they complement intermittent wind and solar power generation without the emission of carbon dioxide to the atmosphere. Rapidly growing shares of these renewables, combined with...

Lean retailing philosophy appears to be manifested in retail industry patterns showing decreasing and historically low retailer inventories. Whether these lean inventory developments translate to better retailer operational performance is still an open question. We empirically examine...

Single-sourcing lost-sales inventory systems with lead times are notoriously difficult to optimize. In this work, we propose a new family of capped base-stock policies and provide a new perspective of constructing a practical hybrid policy combining two well-known heuristics: base-stock and...

We study a multi-location newsvendor network when the only information available on the joint distribution of demands are the values of its mean vector and covariance matrix. We adopt a distributionally robust model to find inventory levels that minimize the worst-case expected cost among the...

Existing literature on dealer liquidity provision and inventory management has focused on dealer inventory costs. I uncover a new inventory benefit channel: dealers strategically build inventory in order to compete for market share. I assess the relative impact of the inventory benefit and costs...

We consider a periodic-review perishable inventory system with multiple demand classes, each characterized by a different lost-sales cost and a least freshness requirement. Demands of different classes in the same period can be correlated, while demands across periods are independent but not...

Problem definition: We study the bullwhip effect and analyze the impact of human behavior. We separate rational ordering in response to increasing incoming orders from irrational ordering. Academic/Practical Relevance: Prior research has shown that the bullwhip effect occurs in about two-thirds...

Service level constraint is often used as a metric to directly control the quality of service (e.g., managing the probability of stock-out) in practice. Many inventory problems with service level constraints are often difficult to solve and are typically approximated by deterministic...

This paper considers a stochastic inventory management problem where a capital-constrained firm can obtain additional working capital through an inventory-based financing facility by pledging its inventory to obtain loans from a lender. We show that it is optimal to deploy a state-dependent...

This article constitutes a first presentation of the prospectus analysis tool developed through a cooperation between the Banque de France and the Autorité des marchés financiers (AMF). This work aims to identify the liquidity management tools (LMT) implemented funds regulated by the AMF under...
