Supply Chain and Inventory Management

Demand, inventory, and production continuously influence one another in supply chains. Sudden demand changes, inaccurate records, production disruptions, and external factors can create irregular fluctuations. Although demand or sales data are often available, inventory and production information may be incomplete or…

Bu çalışmada, talep esnekliği temelli firma fiyatlama davranışı mikro iktisat teorisi çerçevesinde analitik ve ampirik olarak incelenmiştir. Mikro iktisat teorisine göre firmaların temel amacı kâr maksimizasyonudur ve bu amaç doğrultusunda firmalar fiyat ve üretim kararlarını marjinal analiz temelinde belirlemektedir.…

In make-to-order (MTO) manufacturing, customer-side issues involving payment, documentation, logistics, or site readiness may postpone shipment after order acceptance, increasing finished-goods inventory, capital tie-up, and capacity inefficiency. Although prior studies mainly address in-production delays or pre-order…

Purpose This study aims to examine how the strategic value of additive manufacturing (AM) is created in edible product supply chains, using the resource-based view (RBV) as a theoretical lens. Design/methodology/approach Drawing on 29 semi-structured interviews with experts from the food, pharmaceutical and AM sectors…

Abstract This paper develops new closed form normal approximations for the ergodic distribution of a renewal–reward process $X(t)$ describing a semi-Markovian inventory model of type $(s, S)$. When demand sizes follow a Weibull distribution with shape parameter $\alpha \ge 3$, the renewal function can be well approxim…

Üretim sistemlerinde belirli bir oranda kusurlu ürün üretilmesi ile ilgili çalışmalar literatürde önemli ve geniş bir yere sahiptir. Bu çalışmalardaki temel varsayımlar; belirli bir oranda kusurlu üretimin varlığı, kusurlu üretim oranının belirli bir olasılık dağılımına göre dağılması, kusurlu ürünlerin kendi içinde h…

Humanitarian supply chains operating in conflict environments face compounding pressures from security checkpoint congestion, demand volatility, and infrastructure disruption – challenges that existing distribution models inadequately address. This study develops the Relief Aid Distribution Planning with Safety Stock…

In modern, globally interconnected markets, supply chain agility, or the competency for rapid adaptation, has become increasingly important. Traditional approaches to enhancing supply chain agility are certain to fall short because none of them capture either the dynamic or decentralized nature of modern supply chains…

Stockouts pose persistent challenges to supply chain management, causing profit losses, damaging customer loyalty and reducing future orders. This paper studies risk-based decision models for a dyadic supply chain, incorporating opportunity costs due to stockouts. We first examine unconstrained mean-risk newsvendor mo…

Global bidders in sequential auctions face exposure risk when bidding for complementary goods whose values differ in uncertainty. We study how auction order affects this risk in a sequential second-price auction with heterogeneous products, where one good has relatively high valuation variance and the other has low va…
