Supply chain simulation

There are a number of simulations on the market that provide indications of imminent threats to future order, operational and supply situations. 

Logically, you will no longer find all of these complex, expensive ERP modules on the right half of figure 38. 

We needed them as long as the previous manual ERP functions were transferred 1 1 to data processing systems. That was progress in the 1960s  

Today we have to ask what we want to do differently and much more efficiently with the computer. What does it offer  

ERP experts recognized as far back as the 1960s that a data processing simulation was needed to replace the restricting manual feasibility study (Fig. 38).

In general, supply chain simulation can be used along the lifecycle of supply chains, that is from supply chain design to support of supply chain operation. In supply chain design, simulation models can support supply network design (decisions on the location, ramp up or shutdown of production or warehousing sites) as well as the adjustment of control parameters such as safety stock at different... 

At present, the trend is moving from the analysis of individual production and logistics systems towards the optimization of entire production networks, that is, the optimization of the distribution to different production locations taking account of the procurement and distribution chain as indicated by the remarks on supply chain simulation earlier in this chapter. However, in particular for these applications there are some challenges in the basic work of providing consistent and coherent data describing the processes at different sites which most likely are located in different countries.

The simulations and models can be as simple as management of databases performing some statistical analysis, or as complicated as a full supply chain simulation. 

The above overview of selected works on supply chain management allows us to draw the following conclusions about the common characteristics of supply chain simulation ... 

Model development complexity is a major issue in supply chain simulation. 

What can be done Our supply chain simulation software visualizes these backlog situations (Fig. 11). Supply chain management can now shorten the critical path in order to make the processes "Procurement Part 1395" and "Sawing" feasible in the near future (Fig. 12). SCM was able to keep the confirmed cus-... 

With our Supply Chain Simulation software (Fig. 13) you pretend to produce the desired services and products requested by your customers. In doing so, you simulate the future order and material flows in your enterprise. But, you only do it in the form of a what if scenario. 

The supply chain simulation initially shows to the SCM the critical paths of work orders dated in the past. The SCM will find in practically 100% of the cases ways of bringing this backlog into the future without changing the confirmed customer deadlines. This work requires highly qualified specialists who are able to assess the processes and is not suitable for automation (Fig. 13). 

The SCM services the process drivers. Using the supply chain simulation, it ensures that not only the feasibility of all process activities is guaranteed, but also their accurate scheduling. Every process driver now has his... 

Depending on the target figures of sales or - even better - the actual customer orders, the supply chain simulation recognizes as far in advance as you want where bottlenecks and oversupply may occur. The specific countermeasures result in the availability of precisely the right amount of resources on schedule and on time in the current and future performance process that are actually required by your orders. 

For consistent planning and control, our supply chain simulation software sets up Wassermann Supply Chains for every order. These can be used to visualize, simulate, control and ensure the feasibility of all processes to be planned and controlled, including resource distribution (materials, capacity, floorspace, etc.). 

By setting up competent supply chain management in your firm - in which you combine all planning, distributing, buying, and controlling functions - the activation of the supply chain simulation and communication with the process drivers, you achieve for the present the optimization ofvour business. 

Our customers simulate all orders, target figures, and queries with our supply chain simulation before making any delivery commitments and before they give the go-ahead for production. 

The SCM is equipped with an electronic supply chain simulation system which reveals all imminent backlog as well as all imminent bottlenecks and waste for all resources required and indicates the causes. Knowledge is better than guesses. 

Due to the responsibility held by supply chain management, the impression could arise that such a "superhero" capable of heading the SCM does not exist. Please defer your judgment until you know more about the indispensable software tool, the Supply Chain Simulation. This tool constantly shows SCM employees where backlog, bottlenecks and oversupply will occur. 

For this reason, we developed a completely different approach to process mapping the Wassermann Supply Chain. The Supply Chain Simulation takes the bills... 

We now have the Supply Chain Simulation which fulfills the requirements of consistent proactive transparency of the entire performance process, such as e.g. 

Overhead activities, provided they affect time or costs of the process, must be included in the supply chain simulation and processed similar to the worksheet work processes. 

Powerful, programmed tools for eliminating backlog rapidly. This ability of the supply chain simulation has proven extremely important, absolutely necessary to its practical application. If these tools are not truly excellent, the SCM has no chance of ever achieving a state free of backlog, let alone maintain it once it is achieved. 

Moiv does the Supply Chain Simulation aid supply chain management ... 

You have to believe that your SCM will do his job with the help of a corresponding Supply Chain Simulation and the cooperation of your most important employees. Practical experience shows time and again that it works. 

If the supply chain simulation notifies supply chain management of an imminent overload for a real bottleneck, the SCM s last recourse - provided changes in the orders (supply chain) do not help - is to contact sales. 

The supply chain simulation is to calculate within seconds data for the future on the basis of the current primary demand (customer orders, targeted goals, queries).
