Inventory Service-Levels In The Customer Supply Chain
TLDR
It is shown that the standard $\alpha-$, $\beta-$ and $\gamma$-service-levels used in inventory theory, when considered from the point of view of a downstream node in the supply chain, provide only limited information about the delay the orders observe.Abstract:
In this paper we consider an inventory location that serves downstream nodes (e. g. production processes, regional warehouses or customers) in a supply chain. It is pointed out, that the overall optimization of logistical processes should be based on the order delivery time as a critical unifying dimension. It is shown that the standard (\alpha-), (\beta-) and (\gamma)-service-levels used in inventory theory, when considered from the point of view of a downstream node in the supply chain, provide only limited information about the delay the orders observe. A procedure for the determination of the probability distribution of the order waiting time in a discrete time periodic (r,S)-inventory system is developed. Implications for the optimization of sub-processes in the supply chain are discussed. Key words: Inventory management - Service levels - Customer order waiting time - Supply chain optimizationread more

Simulation-based optimization methods for setting production planning parameters
TL;DR: A framework for hierarchical production planning is presented which is used to identify good settings for three planning parameters, namely planned leadtimes, safety stock, and lotsizes, within a discrete-event simulation which mimics the production system.

Supply chain inventory optimization with two customer classes in discrete time
TL;DR: In this paper, a single-item inventory system where two demand classes with different service requirements are satisfied from a common inventory is considered, and a critical level, reorder point, order quantity or (s, q, k) policy is in use.
