Your production orders are caused by sales orders. The ERP system must have strong statistical capabilities in order to support the sales forecasting process. An ERP system geared to make-to-stock production can in one aspect make life for your purchasing department easier: You should take measures to reduce the risk of inefficiency and wastage.

Sales orders must be translated into production orders. We then approximate the production time distribution with a phase-type distribution and show that the optimal policy can be characterized by a reorder point and state-dependent rationing levels.
In this case production planning is based on a sales forecast for a certain time, a year, six months or a quarter. Your ERP system must enable you to be flexible. Some purchase components you keep in stock, others you purchase when needed. The major difference is that in make-to-order, production orders are linked to one or more sales orders whereas in make-to-stock production, orders are the result of production planning, which in its turn is based on a sales prognosis.
Our numerical examples indicate that a critical stock level policy, which ignores information on the status of current production, performs very well.
Your purchasing department must be able to act quickly and look for alternative suppliers fast when a preferred supplier cannot deliver. Research Area s batch production, inventory rationing, make-to-Stock, production and inventory control Fingerprint.
Let us have a look at make-to-order first and see what implications it has for your ERP system, then focus on make-to-stock and finally draw our conclusions. Some components are used in different machine models. If you are a registered author of this item, you may also want to check the "citations" tab in your RePEc Author Service profile, as there may be some citations waiting for confirmation.
However there is still need for flexibility to adjust to suddenly changing market circumstances. We have no references for this item. The ERP system must have a strong and intelligent link between the sales order module and the production process module in order to transfer sales orders into production orders.
More services and features. There is much room for achieving a highly efficient and effective manner of production. The ERP system should strongly support the inventory manager and the purchasing department, to ensure an uninterrupted flow of components and to keep stocks as low as possible.
You can help correct errors and omissions. Just-in-time delivery arrangements must be made beforehand. Assuming that there is at most one order outstanding at any point in time, we first address the case with the general production time distribution.

Combining production orders as much as possible and refining the production process to its maximum potential can reduce this risk. The optimal production policy can also be characterized by a critical work storage level.
Please note that corrections may take a couple of weeks to filter through the various RePEc services. The components for the machine are either to be manufactured or purchased. Sorry, we are unable to provide the full text but you may find it at the following location s: The purchasing module of the ERP system must have this information readily available.
In a make-to-order environment production planning and purchasing can be quite hectic. The transformation of a sales forecast to a production planning is roughly similar to that described above.
We show the monotonicity of the optimal reorder point and rationing levels for the outstanding orders, and generate new theoretical and managerial insights from the research findings.Inventory rationing in a make-to-stock production system with several demand classes and lost sales.
Abstract: We consider production and inventory rationing of a product to fulfill multiple demand classes in a make-to-stock production system with a failure-prone machine. Demand that cannot be satisfied immediately is lost and incurs a lost sales cost, which differs from class to class.
Production Control and Stock Rationing for a Make-to-Stock System with Parallel Production Channels Önder Buluta, Mehmet Murat Fadıloğlu*b aDepartment of Industrial Engineering, Yaşar. In this article, we study optimal production and admission control policies in manufacturing systems that produce two types of products: one type consists of identical items that are produced to stock, while the other has.
This article considers the problem of production control and stock rationing in a make-to-stock production system with two priority customer classes and backordering.
The problem is formulated as a queueing control model. With Poisson arrivals and exponential production times. The processes of make-to-order and make-to-stock are similar at first sight.
The major difference is that in make-to-order, production orders are linked to one or more sales orders whereas in make-to-stock production, orders are the result of production planning, which in its turn is based on a sales prognosis.Download
