Over the years since the advancement of inventory management and fuzzy set theories, a
vast number of studies have been published to integrate these concepts. Nonetheless, no …

In this paper, a multi-period, multi-product, multi-site, multi-sales channel aggregate
production planning problem including ordering preferences is presented in an integrated …

Multi-objective integer linear and/or mixed integer linear programming (MOILP/MOMILP) are
very useful for many areas of application as any model that incorporates discrete …

This paper addresses the differential pricing and lot-sizing problem for a perishable item
with multiple demand classes under a two-level trade credit. The distributer sells a single …

In this paper, a novel method is proposed to support the process of solving multi-objective
nonlinear programming problems subject to strict or flexible constraints. This method …

In the real world markets, demand is influenced by different parameters. Recently, many
researchers have been interested in integrated production and marketing planning …

Fuzzy geometric programming (GP) is an important optimization type. In this paper, first the
origin of fuzzy GP is introduced, some recent research findings of its theory have been …

In this paper, we proposed a generalized economic order quantity (EOQ)–based inventory
model using a trade credit policy in a fuzzy sense. The trade credit policy adopted here is a …

This paper investigates the uncertain maximum flow of a network whose capacities are
random fuzzy variables. We have developed the expected value model (EVM) and the …

We address an inventory-marketing system to determine the production lot size, marketing
expenditure and selling prices where a firm faces demand from two or more market …
