Presentation Goals

Is the current state of our project well defined?

Is the information presented relevant to the project goal?

Is there any missing information that you believe would be helpful?

Feedback and questions are encouraged

Project Scope

Establish synchronized flow between scaling, mixing, dividing and packaging steps in frozen cookie production for optimal productivity.

Scaling

Mixing StageDividing

Defining Current State

Undefined variability in and around the production line There is a bottleneck between the mixing and dividing steps Underutilization of resources Scheduling issues Use of overtime Lack of standardization Production delays

Dividing

Dividing Station

The following timeline shows value-added (colored sections) vs. non-value added (white sections) activities.

Each color represents one troughThere is not continuous flow within the

station

Planned vs. Actual Dividing Time

The following graph shows the scheduled vs. the actual time for frozen cookies on the divider

Actual vs. Scheduled Packaging Times

Conclusions

Variability derives from other production lines that are sharing resources Mixer with Commercial cookies Blast Freezer with Cakes, Muffins & Doughnuts

Changeover time is not accounted for in scheduling

Planned vs Actual cycle times are not consistent

Labor intensive tasks on Mixer yields high variability in cycle times

Unplanned production adjustments affect scheduled availability of shared resources

Open items & future work

Observation on the pre-scaling stationFurther analysis on commercial line change

over timesFurther analysis on variability in the cake,

muffin and doughnut lines Identify most effective and feasible solutions
