Given multiple products with unique lumpy demand patterns, this paper explores the determination of both the lot size for each product and the resource allocation among the products, given an investment budget for production rate improvements. Each product’s optimal production policy takes on only one of two forms: either continuous production or lot-for-lot production. A heuristic procedure de...

biodegradable nanoparticulate carriers, have important potential applications for administration of therapeutic molecules. chitosan based nanoparticles have attracted a lot of attention upon their biological properties such as biodegradability, biocom-patibility and bioadhesivity. the aim of the present investigation was to describe the synthesis and characterization of novel biodegradable nano...

It is now widely accepted that both large and small lot sizes can cause long lead times and consequently bad customer service in terms of late deliveries. The impact of the lot size on the lead time consists of a convex relationship, implying an optimal lot size minimising average lead time. In order to educate people with this undoubtedly correct, but yet controversial issue, we developed an e...
