We studied the inventory control of deteriorating items for suppliers under VMI model. The cost structure and the optional strategies for this model were first discussed. Bi-level programming models of integrated delivery strategies were established. We introduced the genetic algorithm to solve the problem. Finally the merit and demerit of each model and the adaptability were analyzed. 2011 Els...

The authors consider in this paper an integrated forecasting production system of the tracking type. The demand rate during a certain period depends on the demand rate of the previous period. Also, the demand rate depends on the inventory level. Items on the shelves are subject to deterioration. Using a model predictive control approach, the authors obtain the optimal production rate, the optim...

A significant amount of work has investigated inventory control problems associated with fresh produce. Much of this work has considered deteriorating inventory control with many models having been proposed for the various situations that exist. However, no researchers have specifically studied fresh produce which has its own special characteristics. Most research categorise fresh produce into ...

This paper assumes each user has more than one queue, derives a new packet-dependant proportional fairness power allocation pattern based on the sum of weight capacity and the packet’s priority in users’ queues, and proposes 4 new cross-layer packet-dependant OFDM scheduling schemes based on proportional fairness for heterogeneous classes of traffic. Scenario 1, scenario 2 and scenario 3 lead r...

<p style='text-indent:20px;'>In recent years, numerous studies have been conducted regarding inventory control of deteriorating items. However, due to the complexity solution methods, various real assumptions such as discrete variables and capacity constraints were neglected. In this study, we presented a multi-item model for items with limited carrier capacity. The proposed research cons...

In this paper, we use market segmentation approach in multiproduct inventory production system with deteriorating items. The objective is to make use of optimal control theory to solve the production inventory problem and develop an optimal production policy that maximize the total profit associated with inventory and production rate in segmented market. First, we consider a single production a...
