| Tiivistelmä: | A simple model of a production process for two products is analyzed. The basic problem is to find an optimal solution to the conflict that production has to meet a given, generally time-varying demand but the sum of costs for variations in production rate and for inventory-holding has to be minimized. A constant production rate results in high inventory-holding costs, whereas small inventory requires variations of the production rate according to variations in demand. In general, the result is some 'production-smoothing'. Conditions for the optimality of simultaneous and separate production are given. Variations of the parameters yield convex and nonconvex Hamiltonians and substantially different solutions. Two examples illustrate the results. |
