Priority Allocation Decisions in Large Scale MTO/MTS Multi-product Manufacturing Systems : Technical report
نویسنده
چکیده
We consider a single stage multi-product manufacturing facility producing a large number of end-products for delivery within a service constraint for the customer lead-time. The manufacturing facility is modeled as a multi-product, multi-priority queuing system. In order to reduce inventory costs, an efficient priority allocation between items consists in producing some items according to a Make-To-Stock (MTS) policy and others according to a Make-To-Order (MTO) policy depending on their features (costs, required lead-time, demand rates). We propose a general optimization procedure that gives a near-optimal flow control (MTO or MTS) to associate with each product and the corresponding near-optimal priority strategy. We illustrate efficiency of our procedure via several examples and by a numerical analysis. In addition, we show numerically that a small number of priority classes is sufficient to obtain near-optimal performances. KEY-WORDS: Make-to-Stock (MTS); Make-to-Order (MTO); Priority allocation; Scheduling rule; Heterogeneous multi-product queuing system.

Case Study for Lot-sizing Problem in Mto Supply Chain Based on Simulation Optimization Approach
Recently, manufacturers are taking a hybrid approach between MTS and MTO. However, most of literature research on production planning concentrates principally on MTS systems. The MTO area has not received the same degree of attention. There are only some research papers which are based on queueing network models that explicitly talk about the Lot Sizing Problem (LSP) in MTO sector. This paper p...
متن کاملMulti-site production planning in hybrid make-to-stock/make-to-order production environment
Today competitive environment has enforced practitioners and researchers to pay great attention to issues enhancing both production and marketing competitiveness. To do so, it has been obligatory for the firms to consider production side activities while customer requirements are on the other side of competition. In this regard, hybrid make-to-stock (MTS)/make-to-order (MTO) production systems ...
متن کاملA Proposed Hierarchical Production Planning Structure for Combined MTS/MTO Environments
From the viewpoint of the relationship between production release and order arrival, production system can be classified into make-to-stock (MTS), make-to-order (MTO), assemble-to-order (ATO), and engineer-to-order (ETO) systems. Production planning is a complicated task which requires cooperation among multiple functional units in an organization. Planning is the consequence of a hierarchy of ...

The research into multi-product production/inventory control systems has mainly assumed one of the two strategies: Make-to-Order (MTO) or Make-to-Stock (MTS). In practice, however, many companies cater to an increasing variety of products with varying logistical demands (e.g. short due dates, specific products) and production characteristics (e.g. capacity usage, setup) to different market segm...
متن کاملMTO-MTS Production Systems in Supply Chains
Increasing cost pressures have led supply chain managers to focus on running increasingly lean and efficient supply chains, with minimal inventory. Indeed, more and more firms are relying on pull or make-toorder (MTO) supply chains to minimize cost and waste. At the same time, increasing competitive pressures are leading to an increased emphasis on customer service. An important element of cust...
