This study presents a cost optimisation model for multi-variety (or multi-type) Recycled Waste Reverse Logistics System (RWRLS). A linear analytical model is formulated which minimises the total reverse logistics costs for multi-variety Recycled Waste Reverse Logistics System (RWRLS) subjected...

In a recent paper, Hoque (2011) developed two single-vendor multi-buyer models with synchronization by transferring the vendor′s lot with equal and/or unequal sized batches. He reported that his proposed models lead to significant cost reductions when compared to the existing related ones in...

Inventory management augments business operations by effective flow of goods and services. It adds to profitability, competitive ability, service optimization, market diversification, etc. This article investigates the role of inventory management in fostering small firms’ growth. The...

Information and communication technologies (ICT) for health or eHealth solutions hold great potential for generating systemic efficiencies by strengthening five critical pillars of a health system: human resources for health, supply chain management, health care financing, governance and service...

Bei dem ifo Konjunkturtest Verarbeitendes Gewerbe werden auch Aspekte der Lagerhaltung und des Auftragsbestands abgefragt. Der Artikel wirft einen Blick auf diese Variablen und den Zusammenhang zwischen diesen. Es zeigt sich, dass auf oberster aggregierter Ebene das Fertigwarenlager und der...

This paper considers model uncertainty for multistage stochastic programs. The data and information structure of the baseline model is a tree, on which the decision problem is defined. We consider “ambiguity neighborhoods” around this tree as alternative models which are close to the...

We consider a problem of dynamic replenishment of parts in the supply chain consisting of single class of customers, company, and supplier. Customers request a service via the WEB-based ordering system and the company supports service using parts which are procured from the supplier. The...

Models of money demand, in the Baumol (1952)-Tobin (1956) tradition, describe optimal cash management policy in terms of when and how much cash to withdraw, an (s, S) policy. However, today, a vast array of instruments can be used to make payments, opening additional ways to control cash...

In this study, we focus on inventory management issues under simultaneously horizontal (equivalently inter-brand) and vertical (equivalently intra-brand) substitution. The analysis is divided into two distinct scenarios: centralized inventory management, where all brands are managed by a central...

The stochastic variability measures the degree of uncertainty for random demand and/or price in various operations problems. Its ordering property under mean-preserving transformation allows us to study the impact of demand/price uncertainty on the optimal decisions and the associated objective...
