TLDR
A material requirements planning simulator with a two-level bill-of-material is used to study the impact of introducing component commonality into an assemble-to-order environment when demand is subject to random variations, and component procurement orders experience random delays.Abstract:
A material requirements planning simulator with a two-level bill-of-material is used to study the impact of introducing component commonality into an assemble-to-order environment when demand is subject to random variations, and component procurement orders experience random delays. By using simulated data, our ANOVA results show that component commonality significantly interacts with existence of demand and supply chain uncertainties, and benefits of component commonality are most pronounced when both uncertainties exist.read more

Design of the optimal feeding policy in an assembly system
TL;DR: This paper describes an innovative and integrated approach to component management optimization within a production/assembly system using an integrated framework that considers both aspects of the problem: the centralization/decentralization of components in order to minimize the total storage costs and the right feeding policies.

Managing uncertainty through supply chain flexibility: reactive vs. proactive approaches
TL;DR: In this paper, a framework that links supply chain uncertainty, the two types of strategies for achieving supply chain flexibility and the relevant objectives to be achieved is presented, where strategies are classified into reactive buffering and proactive redesign strategies.

Uncertainty Factors in Real Manufacturing Environment
TL;DR: In this article, a comprehensive and up-to-date review of the existing literatures on manufacturing under uncertain conditions is presented, where the authors have identified the various sources and factors of uncertainty in manufacturing/production environment and adjusted the focus on the techniques and models used to tackle the storms.

“Supermarket warehouses”: stocking policies optimization in an assembly-to-order environment
TL;DR: In this paper, the authors apply an innovative step-by-step procedure to support materials management decision-making policies in order to define when, how, and where it is convenient to install a supermarket warehouse, considering the typical aspect of an ATO environment: number, type, position of the assembly systems, demand rate and commonality degree of components used, internal transportation equipment and transportation costs, load unit capacity, space cost for stocking, space availability in the plant, inventory costs, and safety stock dimension.

The Effect of Commonality on Safety Stock in a Simple Inventory Model
TL;DR: In this article, the authors examined the effects of component commonality on optimal safety stock levels in a two-product, two-level inventory model, where the criterion is to minimize system safety stock subject to a service level constraint.

Aggregate Safety Stock Levels and Component Part Commonality
TL;DR: In this article, the authors developed a relationship between aggregate safety stock inventory levels and component part commonality, and a simulation experiment strongly supported the functional form of this relationship in an uncertain operating environment.

Component Commonality with Service Level Requirements
TL;DR: In this article, the effect of commonality on safety stocks in a simple inventory model was investigated and the results were not all intuitive, while utilizing commonality is beneficial, nothing general can be said about the resulting change in the components' stock levels.

Inventory-Service Optimization in Configure-to-Order Systems
TL;DR: A nonlinear optimization model with multiple constraints, reflecting the service levels offered to different market segments is developed, and an exact algorithm for the important case of demand in each market segment having (at least) one unique component is developed.
