Fuzzy set theory has a remarkable progress in the field of research. It initiates many areas in
both practical & theoretical studies. It is really useful for several people engaged in research …

This article investigates the effects of lost sales reduction and quality improvement in an
imperfect production process under imprecise environment with simultaneously optimizing …

In this paper, an inventory model considering items with imperfect quality is developed in
fuzzy environment, wherein shortages are allowed and are backlogged. In order to detect …

The present paper aims to develop an economic order quantity (EOQ) model for the items of
imperfect quality with a joint effect of proportionate discount, backorder, clustering with …

In this paper, a multi-item classical newsboy problem is formulated, occurring both fuzziness
and randomness with floor space constraint. Here, the demand is considered as a random …

This paper presents both crisp and fuzzy EOQ models for defective items present in each lot
when shortages are allowed and backorder takes place. The aim of the work is to first …

The basic assumption of the classical inventory (EOQ/EPQ) models is that% 100 of items
ordered/produced are perfect. However, in most of the production processes, it is …

In this paper, we are going to exhibit an inventory model in which shortages are permitted
and that can be completely replaced. The model is derived to compute the economic order …

Quantity (EOQ) inventory model where the lot produced with a fraction of imperfect items.
Firstly, to explore this model two different categories are considered, without back order as …

Klasik ekonomik sipariş/üretim miktarı (EOQ/EPQ) modelinin en önemli varsayımlarından bir
tanesi sipariş verilen/üretilen partideki ürünlerin tamamının kusursuz olmasıdır. Ancak bu …
