Your average material planner has to take care of from 100.000 up to one million bits of data - and keep them up to date as well. Which means, there is more data for him to keep accurate than he has minutes of work time in an entire year! For that reason, A&K’s CEO Dr. Bernd Reineke has developed a simple plan, containing eight steps, to readjust things and make planning and scheduling more comfortable.
Finally demands boom – and then the readiness for delivery fails! Does it take a more visible sign of too many companies relying on imperfect demand forecasts? Companys which work with more precise forecasts, in contrast, were able to react much faster to recession as well as the booming market.
Are my stocks too high? How much could we reduce stocks and still keep up our readiness for delivery? Will hiring external specialists be profitable? These and similar questions are surely familiar. The E:S:A – Excess Stock Assessment developed by Abels & Kemmner can answer these questions precisely, comfortably and quickly, basing on item specific data.
The stock market demonstrates how it works: Supply and demand dictate the price. But can the forces which apply to stock exchange be applied to demand forecasts? Could it be possible to produce much more in syncronism with the market?
Lot size optimisation is one of the favourite topics of dissertations. And yet more concepts for and dissertations about the determination of correct lot sizes appear, proving that there is apparently a need for more theories about lot size optimisation. Prof. Dr. Kemmner explains the most recent theories in this professional article.
The perfect material planning has two goals: it is supposed to maintain the demanded readiness for delivery and keep stocks as low as possible at the same time. As stock lists usually contain many thousands of items, keeping every single forecast and planning parameter up to date and optimised is beyond the ERP systems settings and even beyond the material planners experience. Depinding on the ERP system, each item has between 30 and 130 of these parameters. Configuring them according to the numerous, company specific influences and dependences requires expert knowledge and mathematically exact forecasts.
Material planning’s and process controlling’s meaning for your company may be best analogized by your body’s heart: They ‘keep pumping’ value and material streams through the entire company’s supply chain. Yet management often shows so little concern for these important tasks, they do not even notice the cardiovascular problems their company has. There are several basic principles, however, which may help to stimulate the commercial circulation.
Prof. H.-P. Wiendahl’s statement “Production is a process which cannot be planned in detail” is just as much set in stone as is Heisenberg's uncertainty principle for quantum physics. With simple words, Prof. Dr. Kemmner will explain, how these theories effect the optimisation of process control.
Stocks generate costs. They also offer safety. But how much safety stock do you need to keep your company from harmfully high or low stock levels? Most companies have the wrong safety stocks in the wrong places – and thus too much stock in total.
Implementation of a factory 4.0 concept in the plastics processing industry requires “scheduling 4.0”. Two management experts explain that this term does not just describe a vision but is already a reality at a well-known injection molder of pond accessories. In the best case, the extra revenue from this essential exercise can finance a company’s own 4.0 strategy.
Long replenishment time and purchasing restrictions such as container completion are a constant challenge in planning. Combined with an enormous variety of changes in the range of goods plus fluctuation in amounts and schedules of demands, this will quickly lead to overstocking or low delivery readiness, when managed in mainly manual planning processes. The trading company Gremlin Electronics Inc.*) in Great Britain has accepted this challenge and reduced stock while raising delivery readiness in the face of slow purchasing and highly fluctuating demands. With the help of some consultancy advice and the application of an APS system, demand planning and material planning improved significantly alongside with IT support.
In projects concerning stock optimisation, the subject of material efficiency is often neglected due to the massive effort that comes with it. Yet, making material efficiency part of the project helps with doing more of the right thing at once.
