The Effect of Alternate Periods of Learning and Forgetting on Economic Manufacturing Quantity

Abstract A method for incorporating the effects of learning and forgetting in the calculation of economic manufacturing quantity is presented. A solution procedure is derived and illustrated by an example.

Sequency on two and three machines with setup, processing and removal times separated

n jobs are to be processed on two or three machines. Each job must be processed in sequence, first on machine I than on machine II, etc. For each job, setup time, processing time, and removal time is known in each machine. Algorithms are developed which determine an optimal sequence that minimizes the total elapsed time. Numerical examples illustrate the algorithms.

The need for worker training in advanced manufacturing technology (AMT) environments: A white paper

The international globalization of the World markets for manufactured goods, particularly consumer goods, has placed an emphasis on nations to improve manufacturing productivity. This need to improve productivity is further prompted by a potential loss of competitive edge in the global marketplace. The market competitiveness and e

Effect of learning and forgetting on economic lot size scheduling problem

Abstract An economic model of maintenance planning for a machine shop is developed. Maintenance can be performed on an individual machine or the entire group of machines simultaneously. The coordinated maintenance on the group would save on the fixed costs associated with separate overhauls. The frequencies of maintenance on each machine within two consecutive coordinated overhauls and the time between these coordinated overhauls is determined. The resulting model selects a solution that is close to the minimum of the total cost of production and maintenance.

A generalized reliability block diagram (RBD) simulation

The paper develops a procedure in Group Technology environment to determine the number of machines, their groupings and the amount of material transfer between the groups, so that all components can be processed within the plant with minimum total cost. The procedure involves further analysing and modifying the solution of an existing GT cell formation method. The factors used in the analysis are machine capacity requirements and between group material handling transfer cost, for each component, as well as the machine cost for each machine. Sequential or non-sequential processing of the components plays an important role in the final grouping and cost.

A framework for training workers in contemporary manufacturing environments

Abstract Production time under the influence of learning and forgetting is examined. Though it can be better described by a power function or by a second degree equation, a linear relationship proves to be a very good approximation. It is also convenient to use in determining optimum manufacturing quantity to a degree of accuracy generally required.

A heuristic procedure for makespan minimization in job shops with multiple identical processors

The paper determines the sequence of set-ups and quantity to produce in each setup if two products are to be produced on a single facility, considering the effects of learning and forgetting. The cost expression which is to be minimized, consists of three factors: set-up cost, carrying cost and the cost of idle facility. A solution procedure is developed and the analysis is extended for the n-product system.
