OK - not in line with current "lean" or "just-in-time" thinking but if that's what management wants to do, then let's talk about how to do it. For the assembly portion of the business, it sounds like you're doing OK with MRP and MPSP driving from the forecast and customer orders. That should continue. For the components, you will have to generate your master schedule by hand. You can do this in MPSP using the "manual" source of demand. This would require that you code each of these component items as a "master scheduled item" in order to have MPSP see them. You cannot "production plan" schedule these items because you are not allowed to include anything but level 0 items in a planning family. So, each component must be manually scheduled through MPSP. You could also use master scheduling in MRP but this has some unique problems. MRP master scheduling always "nets" inventory against demand. This means that you would have to continually inflate the requirement to be able to generate more planned orders for items that you already have in stock. These topics are explored in my book "MAPICS Planning". I have about 100 copies left in stock if you're interested. Just as another tip - I have been working with a company called Systems Plus that has a product called OTTO that provides outstanding visibility for those times when you are building components to fulfill customer orders at the same time you're building for stock. It sorts out where everything is going and allows you to properly prioritize the items that are really needed soon against the ones being built for stock. Check out www.systemspluscorp.com for more information. OTTO embodies a process I call "RPM" which is explained in the press release found on my web site www.daveturbide.com Good luck. Subject: RE: Need ideas please. Outside the Box(for us) To: mapics-l@midrange.com From: mbennett@kimray.com Date: Thu, 27 Jun 2002 16:03:44 -0500 Reply-To: mapics-l@midrange.com Manufacturing has the capacity to produce more parts than Assembly has the capacity to transform into end items based on a 40 hour week at the current manpower levels. There is a no layoff and a no reduction in hours paradigm that must be honored. There is also a reluctance to move people from manufacturing to assembly. Therefore the decision has been made to run manufacturing at its current full capacity and build manufactured parts inventory. They are aware of the higher inventory $ and that's OK. We want to try to use inventory as a way to level capacity in manufacturing and stick to 40 hour weeks Our typical peak end unit periods are the winter months. It is better for us to put in overtime in assembly because of the short lead times (1 day), the smaller lot sizes (5 - 20) and less expertise. Obsolescence is not a problem. 54 years old and still selling repair parts for units built back then. Dave Turbide <dave@daveturbide To: mapics-l@midrange.com Sent by: Subject: RE: Need ideas please. Outside the Box(for us) Why does management want to drive the component operation differently from the product? Is it a matter of excess capacity at the component level and they're looking for "efficiency" or "utilization"? If so, they'd netter be prepared to swallow a higher inventory and some obsolescence risk. If it's a lead-time issue - want to stockpile major parts and components to support assemble-to-order, - the challenge is making the right components and holding the right quantities. That's going to be tough to do if the lower level items are not being driven by forecast.
