Pull scheduling

Pull scheduling. This ensures that production is pulled by demand and not just pushed, for example, by forecasts which may result in levels of stock that are either too high or too low. Pull scheduling is usually implemented through a simple but effective signal card system (the kanban system). 

Leveled production. This is a production planning technique which aims at aligning the product mix and lot sizes with demand in order to capture the full benefits of pull scheduling. 

Samples are scheduled to be pulled based on the time points listed in the stability protocol. Many companies allow a brief time window at the scheduled time point for this activity. This is to allow for weekend pull dates or other unanticipated situations. Pulling schedules should depend on the age of the sample as well as the conditions at which it is stored. 

Delegating routine material control transactions to the shop floor, this simple to operate, visible control system provides a means to organise supply as appropriate, to synchronise part movements during the course of manufacture. Pull scheduling sees parts pulled from preceding processes in line with demand. Kanban can be classified into three basic categories ... 

Improvements in relational as well as operational performance developed a virtuous circle for both parties. Implementing pull scheduling in the supply base necessitated the simultaneous implementation of a partnering strategy. The demise of the traditional arm s length approach to managing the buyer-supplier exchange helped both parties to improve their business volumes and performance over this period. 

Given zero changeover costs, the EBQ formula obeys the JIT ideal of pull scheduling - only make in response to actual demand. Actual demand, of course, is likely to vary from one day to the next, unlike the assumption for demand rate shown in Figure 6.3 above. Pull scheduling is more sensitive to demand changes, because only what is needed is made. 

Explain the difference between pull scheduling and push scheduling. Under what circumstances might push scheduling be appropriate ... 

In the longer term, suppliers should integrate demand information into their organisation and develop the capability to drive production with it. This helps to replace the traditional push scheduling, based on forecasts and buffer stocks, with pull scheduling, based on meeting known demand instantaneously out of manufacturing. 

In contrast to the minds-on approach of the study guide is Explorations in Conceptual Chemistry A Student Activity ATzwzW written by Jeff Paradis of California State University—Sacramento. Unlike the laboratories of a traditional lab manual, these activities are short and relatively easy to set up. They can be scheduled direcdy into the course syllabus or alternatively pulled together on the fly based upon student need as the semester progresses. The majority of these activities can be performed by students during class, which is a surefire way to maintain student interest. Many can also be performed by students outside of class as prescribed by the instructor. The primary goal of this booklet is to allow the student to learn chemistry by doing chemistry. 

Linda McGown It is really terrible, but I do think a lot of the problem is perception, because it hasn t been that way for me. I am not always happy, but I still choose to remain in academia. I have never opted out because deep down I love it, and I hope that I am an example to my students and to other people that you don t have to do things according to some schedule that other people give you. Just take the flak and tell your students to take the flak because academia is worth it. Others have no business telling you what to do with your time, if you are pulling your load. 

A few alternatives to scheduling the work are possible. All samples can be taken based on their pull date and the samples remain in the laboratories... 

The Englishman could not contain his excitement. He canceled all his commitments and pulled together the most important of his books, and now here he was, sitting inside a dusty, smelly warehouse. Outside, a huge caravan was being prepared for a crossing of the Sahara, and was scheduled to pass through Al-Fayoum.

As inventory is maintained at various warehouses as well as the manufacturer, a large amount of material can be sitting in inventory in the supply chain. As replacement orders pass down the supply chain, the orders are pulled from the inventory that is available. If we look at a simple example of a retail store to a warehouse to the manufacturer, the order quantities will be smaller from the retail store to the warehouse, which will try to cover the orders quickly with inventory. When the inventory reaches a low level at the warehouse, a larger replacement order is placed with the manufacturer. The retail store may order 10 items per week, and the warehouse has an inventory of 100 items. For nine weeks there are no orders placed to the manufacturer and in the tenth week an order for 100 items is placed. If the manufacturer had 100 items in inventory they would have been held for more than nine weeks before they could be shipped to the customer. This adds storage costs to the manufacturer and can disrupt the production schedule when the large order arrives. This reaction in the supply chain is called the bullwhip effect. ... 

Implementation of the Pull System There are two basic principles of production planning and control, the push and the pull principle. The push principle targets the maximum efficiency of given capacities. Hence, it is a typical representative of the ideology of mass production. One of its main characteristics is a centrally planned production schedule. While typical sellers markets of the last century could be served satisfy-ingly with this principle, today s buyers markets require more flexibility of production systems. Since real customer demands are not considered accurately by the push principle, big stocks and delivery problems - and with it waste - occur often.
