Kartläggning och analysering av produktionsplanering av order med specialkvalitet hos Stora Enso Packaging AB
Abstract (Summary)This investigation’s task was to map manufacturing of special qualities at Stora Enso Packaging under a certain period, analyze if rules concerning special qualities is followed, which consequences this results in concerning use of paper, waste and costs and to give suggestions on alternative solutions. The goal was to give sugges-tions that help the company to reach its business ratio that the production de-partment uses within use of paper and productivity in the corrugated cardboard machine.Stora Enso Packaging is a part of the forest group Stora Enso and is one of Swe-den’s leading producers of corrugated cardboard. Stora Enso Packaging acts pri-mary on the Swedish market, where they have a market share of 25 %.To be able to analyze orders with special qualities we did a data collection during two months, where we mapped incoming orders. The period for this mapping was set to 1 February – 31 March 2006. It was considered enough to see it as an aver-age for the whole year, as there were no mentionable season variations.There is given written rules for special qualities in Stora Enso Packaging’s manual for quality standard. The rules say that an order shall be at least 5000 m2. 177 of 270 orders in our investigation were less than 5000 m2, while 93 orders fulfilled the demands. The result clearly shows that most of the orders are not following the rules, which is quite remarkable considering the importance of effective plan-ning of the corrugated cardboard in the machine.One of Stora Enso Packaging’s four business ratio in the production department is the use of paper. Therefore we examined the use of paper for every single order dur-ing the data collection period and we show the result in three diagrams, partly for all orders and partly for orders over respectively under 5000 m2. The result shows that all orders that have a use of paper less than 50 % has also fewer than 5000 m2. It also shows that most of the orders have a use of paper between 91 100 %.The additional cost for the waste of corrugated cardboard was 83 % higher in SEK for orders over 5000 m2, compared with order under the same square meter limit. An important comparison is that orders over 5000 m2 are 7 times bigger in square meters than orders under 5000 m2. Of this comparison one can see that the addi-tional cost is bigger per ordered square meter for orders under 5000 m2. Further-more, the same indication shows when we compared the additional cost for waste with the revenue for every single order. Order under 5000 m2 shows a result of 12,5 %, while the same result for orders over 5000 m2 is 9,5 %. This shows an indi-cation of that orders under 5000 m2 increases the costs and decreases the productiv-ity in the plant.
