Ruttplanering

This report is the final part within our education, Industrial Organization and Economy focusing on Logistics and Management at Jönköping School of Engineering. The aim with this report is to coordinate recycle drives for deposited aluminum-cans and bottles collected from grocery stores within Jönköping county and locality.In the present situation both aluminum cans and bottles filled with drinks are distributed to the grocery stores by the brewery?s own distributers. At the same time as they supply the drinks they also discharge the grocery stores units with restored aluminumcans and bottles. To make it easier for the grocery stores to handle the goods in the future, all distribution of drinks ought to be directly delivered to the grocery stores own separate central warehouse. This means every brewery ought to instead supply their drinks to the grocery stores central warehouse instead of taking them directly to the grocery stores. The drinks will then be distributed from the central warehouse to the grocery stores in connection with their orders of provisions. Due to hygienic reasons it is not possible that the deposited units are transported together with the provision.Therefore a kind of recycle drive needs to be organized.By using computer-aided route planning systems every transport are optimized, which means the transportation and labour costs will be reduced. At the same time the strain on the environment will also be a reduced. The company, DPS Europe, an international supplier of professional designed route planning systems. They have assisted with computer software and support during the study. The software PlanLogix build optimized drive routes based on different presumptions, restrictions and parameters which is based on information given by Returpack, responsible for the Swedish bottle refund system.A week?s work requires 19 shifts, three shifts on every work day and two shifts on the weekends. How many times the deposited units need to be collected varies between each grocery store. It differs from seven times a week to one time every forth week. This will lead to a four-week schedule with 76 routes. The total cost for the bottle refund system is 603 459 SEK/four weeks, and the filling degree on the vehicles will be approximately 50 percent.If a bottle refund system is to be implemented it needs to be profitable for the environment, meaning the positive effects need to exceed the negative effects, which the transports cause. To implement deposit drives, the units of aluminum-cans and bottles needs to be higher so the filling degree increases. A proposal to increase the filling degree could be to decrease the number of times each grocery store gets their deposits collected. This will increase the filling degree since at every occasion there will be more units to collect and at the same time decrease the transportation.
