摘要:

AbstractIn some factories production epochs occur that allow system components to be replaced at reduced cost. Over a long production run the unit cost of replacing these stochastically deteriorating components can be controlled by decisions which govern when production is to be interrupted for component replacement and when components are to be replaced at the reduced cost replacement opportunities. This paper develops and analyses models for optimizing "interrupt and opportunistic" replacement strategies in simple systems. Numerical results are given that illustrate the advantages of combining interrupt replacement with opportunistic replacement.

摘要:

AbstractTo date, large geometric programs have been difficult to solve. This paper presents a simplex-based approach to the solution of such programs which is indifferent to the degree of difficulty of the problem. Furthermore, unlike many gradientsearch techniques its success is not dependent upon a "good" starting point.

摘要:

AbstractThe paper describes initial simulation work on various factors associated with production and inventory decisions. The machine shop model which was used comprised one machine only on which a small product range is manufactured. The effects of variations in output mix and demand levels on the rate of return on investment is examined. The necessary adjustments in stocking policy for an economic level of capacity utilization are indicated, and a "capacity profile" is produced which reveals the efficient operating frontier for the different cases. The direction of further experiments is indicated.
