A recursive exact algorithm for weighted two-dimensional cutting

Article Abstract:

A new exact algorithm is suggested which is better than Gilmore and Gomory's algorithm for solving unconstrained guillotine two-dimensional stock cutting problems and Herz's algorithm which is applicable only for unweighted conditions. The new algorithm works well both for weighted and unweighted situations. The algorithm employs dynamic programming processes and one-dimensional knapsack problem to derive efficient lower and upper bounds and significant optimality criteria which allow an important branching cut in a recursive tree-search process.

A multi-product continuous review inventory system with stochastic demand, backorders, and a budget constraint

Article Abstract:

Budgetary or storage space constraints are characteristics of inventory systems. A multi-item stochastic inventory system is examined to reduce the expected value of approximate total annual cost.
