Production costs in general, and workforce and inventory costs in particular, constitute a large fraction of the operating costs of many manufacturing plants. We introduce cooperative aggregate production planning as a way to decrease these costs. That is, when production planning of two or more facilities (plants) is integrated, they can interchange workforce and products inventory; thus, thei...

In a manufacturing system with flexible capacity, inventory management can be coupled with capacity management in order to handle fluctuations in demand more effectively. A typical example is the effective use of temporary workforce. In this paper, we discuss an integrated model for inventory and flexible capacity management under nonstationary stochastic demand with the possibility of positive...

This paper presents a vendor-buyer integrated inventory model. This paper considers the problem of a vendor and buyer integrated production inventory model for the vendor and the buyer optimization model under quality improvement investment and setup cost reduction in the production system such that the total profit is maximized. The relationship between demand and price is considered as a line...

An integrated scheduling system with demand forecasting has been developed. The SARIMA (seasonal autoregressive integrated moving average) model is automated to forecast the demand. In order to reduce the cost and instability of production scheduling, a safety inventory determination is also automated additionally. A scheduling system based on the mathematical model and the efficient optimizati...

The integrated production, inventory and distribution routing problem (PDRP) is concerned with coordinating the production, inventory and delivery operations to meet customer demand with an objective to minimize the cost. The particular PDRP that we consider in this study also involves heterogeneous transporters with non-instantaneous traveling times and many customer demand centers each with i...

Background and Objectives: Monotheistic integrated psychotherapy is regarded as a multidimensional and comprehensive therapy recommended for the treatment of abnormal behaviors, mood and anxiety, personality, and drug use disorders. The purpose of this study was to investigate the effect of monotheistic integrated psychotherapy on the resilience, anxiety, and depression levels among prisoners. ...

Under the assumption that the replenishment lead time is dependent on both lot size of the buyer and production rate of the vendor, an integrated production inventory model is presented in this paper. The decision-making interaction of lead time between a buyer and a vendor in the integrated inventory model is analyzed. In terms of the model, a solution procedure has been developed to obtain th...

An efficient humanitarian inventory control model and emergency logistics system plays a crucial role in maintaining reliable flow of vital supplies to the victims located in the shelters and minimizing the impacts of the unforeseen disruptions that can occur. This system should not only allow the efficient usage and distribution of emergency supplies but should also offer the ability to be int...
