Scm models and optimisation

All models can be created quickly and provide good solutions in less than one week. More sophisticated optimization algorithms take into account stackability constraints, load and unloading rules, palletizing logic, warehouse efficiency and load stability with an objective to reduce transportation spend minimize 'shipping air'.

That demand information can be in the form of forecasts, with defined time fences that convert those forecasts to order, or blanket orders.

Simulation models, on the other hand, can represent uncertainty with underlying distributions. But does your customer know what it actually wants—and when it wants it?

Incorporating probabilities such as these into models can be "mathematically and computationally difficult," Gue says. Despite a down market, inventory turns have increased from six to eight a year. Model results are easily implemented. Whilst most software vendors are offering supply-chain optimization as a packaged solution and integrated in ERP software, some vendors are running the software on behalf of their clients as application service providers. All partners in the supply chain will work toward the same set of intentions simultaneously. Because the movement of product to meet the model stock, called the stock transfer, needs to be in economic shipping units such as complete unit loads or a full truckload, there are a series of decisions that must be made. Changes in variables such as demand patterns, carriers, product lines, and customer and supplier locations can make models obsolete. Models are percent accurate. The technical ability to record and manipulate larger databases more quickly has now enabled a new breed of supply-chain-optimization solutions to emerge, which are capable of forecasting at a much more granular level for example, per article per customer per day.

You know which suppliers you already use, so the RFI is an opportunity to understand the infrastructure, financial strength, and capabilities of new suppliers. How often you need to model depends upon your supply chain environment.

It should also factor in risks and unexpected constraints that often affect a global supply chain's efficiency, including sudden spikes in fuel costs, material shortages, natural disasters such as hurricanes, and instability of global politics. Applications[ edit ] Typically, supply-chain managers are trying to maximize the profitable operation of their manufacturing and distribution supply chain.

And, yes, your customer might even send you long-term or blanket orders. Today, Saturn is nearly two-thirds of the way to converting its transportation to the dedicated delivery system it shares with GMSPO. Gathering the data to support the modeling effort is quick and painless. This is generally achieved by continuing to add time-phased requirements until the loads meet some minimum weight or cube. Consider these supply chain modeling myths identified and dispelled in a white paper by Schneider Logistics Inc. Saturn manages inventory for its retailers, so the bulk of deliveries are replenishment shipments. But does your customer know what it actually wants—and when it wants it? But where do you start? Then, using this forecast demand, a supply-chain manufacturing Production Planning and distribution plan is created to manufacture and distribute products to meet this forecast demand at lowest cost or highest profitability. They do, however, need to know enough "to be smart consumers of modeling technologies, and be able to ask smart questions and understand the terminology," he says. You know which suppliers you already use, so the RFI is an opportunity to understand the infrastructure, financial strength, and capabilities of new suppliers. The algorithms used are similar to those used in making financial investment decisions; the analogy is quite precise, as inventory can be considered to be an investment in prospective return on sales. Supply chain modeling is purely a mathematical exercise. Agere's move to daily planning was driven by its desire to provide customers with better service and the ability to carry less inventory.

Approaches and solutions[ edit ] The classic supply-chain approach has been to try to forecast future inventory demand as accurately as possible, by applying statistical trending and "best fit" techniques based on historic demand and predicted future events.

Optimization solutions are typically part of, or linked to, the company's replenishment systems distribution requirements planning, so that orders can be automatically generated to maintain the model stock profile.
