This paper considers the multi-item inventory lot-sizing problem with supplier selection. The
problem consists of determining an optimal purchasing plan in order to satisfy dynamic …

This paper investigates a dynamic lot-sizing problem with supplier selection, where the
manufacturer develops an aggregate plan to meet product delivery demand with the …

In this study, a two-phase algorithm has been developed to address the single-product
supplier selection and order allocation problem (SP-SSOAP). In the first phase, a novel …

The multilevel capacitated lot-sizing problem (MLCLSP) is a vital theoretical problem of
production planning in discrete manufacturing. An improved algorithm based on the genetic …

In this paper, we consider the capacitated three-level lot-sizing and replenishment problem
with a distribution structure (3LSPD-C), recently proposed in the literature. In 3LSPD-C, a …

Purpose: In this paper, the flexible manufacturing system lot-sizing with the co-production
problem is modeled. It is also simplified using the relationships between variables. One of …

The goal of production planning in a refinery is to produce as many valuable products as
possible such as gasoline, jet fuel, diesel, etc., while meeting market demand and other …

هدف از برنامه‌ریزی تولید در یک پالایشگاه، تولید هرچه بیشتر محصولات با ارزش مانند بنزین،
سوخت جت، گازوئیل و غیره و درعین‌حال تأمین تقاضای بازار و سایر محدودیت‌ها است. پالایش نفت …‎
