چکیده:
We examine the role of inventory in a hybrid Make-to-Stock (MTS)/Make-to-Order (MTO) production environment, based on a case study performed in a fruit juice company. In this example, demands for Finished Good (FG) inventories follow normal distribution .We propose a model to calculate economic order quantity (EOQ) by obtaining demands for Raw Material (RM) inventories through Work-in-process (WIP) and FG inventories. For validity of our claim we illustrate some samples of production in different days and compare it with old method estimation of WIP and EOQ.

"ir ABSTRACT We examine the role of inventory in a hybrid Make-to-Stock (MTS)/Make-to-Order (MTO) production environment, based on a case study performed in a fruit juice company.
2. Related works Hybrid MTS/MTO system have attracted attention of the researchers in recent years and there are some studies about lead time, accepting or rejecting orders, controlling and sequencing ,investigating three level of hierarchical production planning (HPP), prioritizing MTO over MTS, etc… Williams [3] proposed a method for analyzing one-stage systems by considering the demand as stochastic with limited interactions and capacity using queuing theory.
Carr and Duenyas [7] developed a model for addressing the joint admission control and sequencing in a hybrid MTO/MTS system was as a simple two-class (MTO and MTS) M/M/1 queue, making suggestions on how a company should react to an extra order, accept it or reject it and then on type of products and quantity of orders when signing a new contract to in the case of MTS.
[10] proposed a decision support system for order acceptance/rejection in hybrid MTS/MTO production system, for helping both company and customer to obtain their desirable need.
They assumed that a production system as single equipment, which was determined by limited capacity, and stochastic demand, measuring several run-out time scheduling and sequencing heuristics and achieved to a comprehensive managerial understanding in the hybrid MTO-MTS environment through an extensive simulation study.
In this paper we examine the role of inventory in a hybrid MTS/ MTO production environment, based on a case study performed in a fruit juice company."
