There are 23 instances for OPL based models:
- 5 instances with 3 products, 3 periods and low production capacity (cp=0.9)
- 5 instances with 3 products, 3 periods and high production capacity (cp=0.75)
- 5 instances with 3 products, 3 periods and low production capacity (cp=0.9)
- 5 instances with 3 products, 3 periods and high production capacity (cp=0.75)
- 3 instances with 7 products, 8 periods and low production capacity (cp=0.9)
There are complementary instances for stochastic programming models:
- For the two-stage stochastic programming with 10, 50, 100, 200 and 500 scenarios
- For the multistage stochastic programming with 12, 20, 30, 39, 42, 110, 155, 240, 258, 399, 420 and 584 nodes
- Remarks: 1) the number of nodes depends on the size of instances.
2) there are instances with small number of nodes that were not considered in the computational experiment.
Characteristics of instances:
