Title: Bottleneck management through materials administration  Course:  4FE05E Authors:  Mikael Karlsson and Johannes Mueller   Examiner: Helena Forslund Key words:  Bottleneck management, material management, process description, timber, procedures Purpose:   The objective of this study is divided into three parts, all three parts of the purpose aim for the same goal. Namely, to improve the material management so that this enables the bottleneck in the planing mill to keep a continuous  flow, and thereby minimizing the risk for production stops at LB-Hus.   Part.  1:  Identify  and  analyze the material management  connected to  the planing mill  in order to identify problem areas. Part.2:  Identify  improvement potential  in the material management connected to the planing mill.   Part.3: Suggest improvements in the material management connected to the planing mill.  Theoretical framework: Process mapping, inventory accounting, balance safety, inventory availability / service levels, safety stock and reorder point, forecasting and routine descriptions. Empirical foundation:  Interviews carried out at LB-House,  illustrated with the help of process maps and a description of each process.   Conclusions:  To work with  the  suggestions  given  and  to  follow  clear procedures  in  all  processes would  result in  a more  efficient  inventory management,  it would also present  a  solution  to  the problem regarding the planing mill being a bottle neck. Suggestions for further research: Review and map the information flow from demand to production start. Determine what is needed for production planning to be carried out. Review the possibility of introducing bar codes and a new and more sophisticated business software.
