K Power K Power has 2 fields from which they obtain fuel for their plants. It is sent to one of two facilities for refinement before being sent to generating plants. Refinery A produces 1 unit from 2 units of input and has a capacity of 50 units per year. Refinery B produces 1 unit from 3 units of input and has a capacity of 75 units per year. Refined fuel is sent to one of two plants. Each unit of fuel produced by refinery B produces 1 unit of power. Each unit of fuel produced by refinery A produces 0.8 units of power.

K-Binding K-Binding is considering a book binding operation at its RC plant. There are 9 steps that include open boxes, collate pages, trim pages, blue backs, attach binding, emboss binding, box books, attach mailing labels and load trucks. Mgmt has asked for a model of the process, the capacity, and recommendations for increasing capacity at minimal cost.
