Order crossovers
نویسنده
چکیده
The control policies that are used in inventory management systems assume that orders arrive in the same sequence as they were ordered. Due to changes in supply chains and markets, this assumption is no longer valid. Therefore, traditional control policies have to be modified in order to be able to manage inventories in case of order crossovers. This paper aims at providing an improved understanding of the phenomenon of order crossovers and the conditions for the occurrence of order crossovers. Order crossovers are caused by differences in lead times and in the time between orders. This paper distinguishes several types of order crossovers according to the source of the differences encountered. It reviews literature on these sources of differences that may cause crossovers. Next, the paper provides a detailed analysis for the case of a tobacco firm that encountered order crossovers. The paper concludes that the type of order crossovers this firm encountered are predominantly expected order crossovers. General order crossovers also occur. Modern ERP systems are not able to handle these types of order crossovers effectively.

High-order jamming crossovers and density anomalies.
We demonstrate that particles interacting via core-softened potentials exhibit a series of successive density anomalies upon isothermal compression, leading to oscillations in the diffusivity and thermal expansion coefficient, with the latter reaching negative values. These finite-temperature density anomalies are then shown to correspond to zero-temperature high-order jamming crossovers. These...
متن کاملDifferential stability of DNA crossovers in solution mediated by divalent cations
The assembly of DNA duplexes into higher-order structures plays a major role in many vital cellular functions such as recombination, chromatin packaging and gene regulation. However, little is currently known about the molecular structure and stability of direct DNA-DNA interactions that are required for such functions. In nature, DNA helices minimize electrostatic repulsion between double heli...
متن کاملAnalysis and management of periodic review, order-up-to level inventory systems with order crossover
In this paper we investigate the (R, S) periodic review, order-up-to level inventory control system with stochastic demand and variable leadtimes. Variable leadtimes can lead to order crossover, in which some orders arrive out of sequence. Most theoretical studies of order-up-to inventory systems under variable leadtimes assume that crossovers do not occur and, in so doing, overestimate the sta...
متن کاملNew Order-Based Crossovers for the Graph Coloring Problem
Huge color class redundancy makes the graph coloring problem (GCP) very challenging for genetic algorithms (GAs), and designing effective crossover operators is notoriously difficult. Thus, despite the predominance of population based methods, crossover plays a very minor role in most state-of-the-art approaches to solving the GCP. Two main encoding methods have been adopted for heuristic and G...
متن کاملA single-item inventory model for expected inventory order crossovers
Expected inventory order crossovers occur if at the moment of ordering it is expected that orders will not arrive in the sequence they are ordered. Recent research has shown that (a) expected inventory order crossovers will be encountered more frequently in future, and that (b) use of a myopic order-up-to policy based on a stochastic dynamic programming approach leads to improved performance co...
