Job-Shop Lot Release Sizes
TLDR
In those cases where management is already using an EOQ method for determining lot release sizes, the input data and system required for the implementation of ELRS is basically similar and therefore the new and improved analysis can be substituted at relatively minor inconvenience to the user.Abstract:
A new model ELRS for determining optimal job-shop lot sizes is presented. Since the setting of the lot release size is one of the most important controlling parameters in the scheduling of a job-shop, the improvement in technique described in the article should result in substantial savings to job-shop operation costs. In those cases where management is already using an EOQ method for determining lot release sizes, the input data and system required for the implementation of ELRS is basically similar and therefore the new and improved analysis can be substituted at relatively minor inconvenience to the user. For those job-shops which set lot release sizes by informal means, the ELRS concept may provide enough of an improved technique to induce this use of this analysis.read more

Determining lot sizes and resource requirements: A review
TL;DR: The fitting of some of these techniques to continuous variables problems gave very promising results; that question is not discussed in detail in the paper, but useful references allowing to deepen the subject are given.

OR Practice-Determining Lot Sizes and Resource Requirements: A Review
TL;DR: It is concluded that capacity limitations, as well as other realities of plant environments, such as scrap, demand uncertainties or inaccurate data, are the Achilles heel of lot-sizing research.

Economic lot size determination in multistage assembly systems
TL;DR: This work considers the optimal lot size problem for multi-stage assembly systems where each facility may have many predecessors but only a single successor, and it is proven that the optimal lots size at each facility is an integer multiple of the lot size at the successor facility.

TL;DR: It is proved that the ratio between the production interval and delivery interval must be an integer in an optimal solution, which provides the basis for a very simple, optimal solution procedure.
