Cooperativa Lavoratori Agricoli Imolesi (€300M in revenue, 500 employees), namely CLAI, is an Italian agri-food cooperative with two plants producing fresh meats and salami. Logistics & Automation Consulting (LAC), a consulting and software company specializing in solving supply chain optimization problems, has developed an optimization solution for CLAI to optimize the packing of food products into boxes for customer delivery. This food box packing optimization solution relies on LocalSolver as a general-purpose optimization engine.
Food box packing optimization problem
200 customer orders per day
For each customer, up to 100 food products to pack into boxes
- Different types of boxes are available, with various capacities
- All products cannot be packed together into all kinds of boxes (mutual exclusion)
- Some products have to be packed into a box before others (precedences)
- Minimize the number of used boxes
- Minimize the number of types of used boxes
- Maximize the use of small boxes
- Minimize the number of different products within each box (to make control on delivery easier)
- Balance the content of all boxes (to make palletization more stable)
Here are the key figures about the resolution of the problem by LocalSolver:
- 10 seconds of running time per customer order
- Solutions with an optimality gap < 0.01% for all objectives
LAC relied on LocalSolver to efficiently model and solve CLAI’s food box packing optimization problem. The resulting optimization software solution is integrated into CLAI’s ERP system and used daily in production. The key factors which convinced LAC to choose LocalSolver against traditional MIP solvers to carry out its service projects are speed, robustness, ease of use, dedicated and responsive support, and last but not least, straightforward licensing and competitive pricing.
