You will design a management plan over the next 100 years (p = 5 periods of 20 years each). This plan is defined by the area cut in each age class in each period (Xij). To begin, you plan on cutting 25% of the total forest area in each 20-year period, preferentially cutting from the oldest age classes. You will then explore other management plans that depend on the objectives you set. 1 Mbf stands for thousand board field
