Pet Food Production Optimization Using Manufacturing Process Simulation Software

Pet Food Production Optimization Using Manufacturing Process Simulation Software

Problem

Perfection Pet Foods is a US manufacturer of extruded pet food, with a focus on ultra-premium products for dogs and cats. For three consecutive years, demand for the company’s products increased annually by approximately 35%, while demand profiles changed as people switched their preferences from big dogs to smaller ones. This was the reason the company decided to optimize their production line and adjust it to the current demand.

The individual stages of the company’s current production line had enough capacity to fulfill new demand profiles, but the altogether production process was not harmonized enough. It was also not sustainable because a lot of waste was generated during the process. All these factors resulted in congestions in storage facilities and great financial losses.

To discover solutions for underperformance in the production process, the company’s executives needed to analyze process phases, schedule them in relation to one another, and then optimize the schedule. They tasked ITE Consult, a strategic planning and simulation consulting company, with the project, which aimed to:

To reach these goals, the ITE Consult team decided to apply manufacturing simulation as a perfect approach for better production scheduling and bottleneck visualization. It would help the team visualize the manufacturing process, get insights into process phases, see how they affect each other, and test various scheduling and production profiles in a risk-free environment.

Production optimization using manufacturing simulation software

Solution

The production process was complicated, so the consulting team split it into three major phases with assigned restrictions, including:

The company produced various types of pet food, so the consultants considered this when analyzing the production process.

To build a production simulation model, the team applied AnyLogic manufacturing simulation capabilities. Using the AnyLogic Fluid Library, the engineers created a model of the shop floor with the production line. With the AnyLogic agent-based modeling approach, they linked all production phases so that they would exchange data, and included the current scheduling and production portfolio in the model.

Then, the engineers used the OptQuest optimizer, which is built in the AnyLogic production optimization software, and set a pool of strategies for each production phase, including parameters for food constraints, restrictions, and time frames for each production phase. The optimizer acted as a global agent and determined strategies that could be used together in the most efficient way, and gave users the optimal decision.

End-users of the manufacturing simulation model would benefit from the easy-to-use interface when applying the model for everyday scheduling. With Excel input files, they could specify demand, production limits, and extruders characteristics. After running the model, they would get a detailed simulation-based schedule of all the processes and all the metrics presented in charts.

AnyLogic process simulation software also enabled the engineers to incorporate Python analyzer into the model. It made data post-processing easier. Users could move back to the production simulation launcher and navigate to Python’s queries, which allowed for a deeper visualization of specific cases and a better understanding of the simulated process.

Outcome

With the help of the multi-objective AnyLogic manufacturing simulation model, built by ITE Consult, Perfection Pet Foods company managed to:

Currently, the model is used on a regular basis for detailed weekly production scheduling to maximize production capacity in the environmental uncertainty.
