Problem StatementImprove efficiency of facility layoutReduce non-value added work & work in processDecrease drying time for painted/primed hive bodies

#

Kelsey

Meaningful employment + exemplary products...a. Optimize the facility layout to increase throughput and decrease productionist man-hours spent on material handling while accounting for the influx of temporary jobs and the space needed to accommodate them.b. Integrate seconds frame production into new schematic.c. Reduce non-value added work and work in process.d. Decrease drying time of primed and painted boxes by investigating solutions to increase air flow.

ObjectivesConduct time studiesUse Systematic Layout Planning (SLP)Line Balancing AnalysisEstablish and improve paint/primer drying timeConduct economic analysisRecommend improvements

Kelsey

Conduct time studies. An understanding of the length of time that it takes for one beehive box to be constructed from start to finish is necessary in order to track overall metrics (man-hours/piece) from the start and end of the project. Analyze the probability of frame reworking and seconds frames. To add robustness to the time studies it is important to account for the probability that a frame needs to be reworked or is damaged during the stapling process. Use Systematic Layout Planning Method (SLP) to determine optimal layout. The project team will utilize a software add on to AutoCad called FlowPlanner which simulates the distance of product travel from start to finish. Adjustments to the layout can be made and distances recalculated until an optimal layout is determined. Research options to increase air flow. The project team will investigate options to decrease drying time for the primed and painted boxes, which is currently highly variable depending on humidity, temperature, and air flow. Recommend improvements in accordance with ISO standards. A set of recommended improvements will be compiled that satisfies the technical (layout and inventory efficiency) and social (employ the most consumers/increase workload) goals of Bridgeway. All recommendations should complement Bridgeway's goal of becoming certified by the International Standards Organization (ISO).

Line Balancing- Introduction

Arielle

Line Balancing- Unique ChallengesTypical Line BalancingInvolves assigning different tasks to same workstation or worker to balance workloadThe ChallengeConsumers and Productionists are limited to very specific tasks based on abilities#

Arielle

Line Balancing- Typical Method#

A new unit enters next workstation every 15 minutesNumber of tasks/worker varies

Arielle

Line Balancing- Alternative Approach#

A new unit enters the next workstation every 5 minutesNumber of workers/task varies

ConclusionsLoss of profit each month due to layoutHive body drying process is longBridgeway's supply from Dadant is inconsistent

#

JordanLoss of profit each month due to improper work cell placement. Hive body drying process must be shortened. Bridgeway's irregular resupply timing and quantities are dragging down the Dadant project's contribution margin.

Project ConstraintsThere are some constraints that the project team must account for, including: Tasks, and how they are completed, must remain the same. Both consumers and productionists are trained by an outside team, and restructuring training and specific tasks is not an option. Productionists must complete all steps involving the movement of materials around the plant. Frame stapling and box hammering must be kept away from the office as they interfere with communication. Stapling equipment is not owned by Bridgeway, and thus is not eligible for possible design updates.
